Increasing concern has been expressed about the potential effects of both synthetic and natural estrogenic endocrine disruptors (EEDs) on human reproductive health in our environment in the last decade. However, little attention is paid to histomorphometric structural changes of the epididymis. We aim to evaluate the chronic exposure effects of phytoestrogens found in aqueous extract of Sesame radiatum leaves on the male Sprague Dawley (SD) rats’ epididymes. Thirty adult male SD rats were randomly divided into three groups (2 treated and 1 control groups respectively). In the treated groups, a single daily dose of aqueous leaves extract of S. radiatum (14.0 mg/kg and 28.0 mg/kg body weight) were administered via gastric garvage, while, equal volume of normal saline was administered in control group for six weeks. Histomorphometric study of the epididymal tissues and hormonal assay were analyzed using SPSS software and P < 0.05 was considered statistically significant. Significant (P < 0.05) body weight gain in a dose dependent was observed in all the animals. Also, there was significant weight gain in both raw weight and relative organo-somatic weight of the epididymis per 100 g body weight. However, the weight gain was more in the high dose than the low dose group. The epididymal lumen appeared wider and fuller with spermatocytes when compared to the control. There is significant (P > 0.05) increases in testosterone level compared to control, however, the low dose was also significantly lower than the control. Sesame improves the storage capacity for the spermatozoa in the epididymis in a dose related manner.

Spermatotoxic impact of bonny light crude oil (BLCO) ingestion on adult male ...lukeman Joseph Ade shittu
Increasing concern has been expressed about the possible declining trend in the sperm quality and sperm count of man as a result of exposure to environmental estrogenic agents in the past few years now. There is a general paucity of knowledge of BLCO ingestion on the reproductive effect. Hence, we aim to evaluate the impact of sub-lethal dose of BLCO ingestion on semen parameters of adult male mice. Initial acute toxicity study was carried out to determine the lethal dose of BLCO, which was calculated to be 37.4 mg/Kg body wt. A sub-lethal dose of 20 mg/Kg bwt /day of BLCO were then given to 8 male mice in the experimental group. While, the control group of 7 animals received equal volume of 0.9% normal saline via oral garvage for 2 weeks. Data were analysed using SPSS 12 statistical software with P < 0.05 considered statistically significant. There was a significant (P < 0.05) weight gain in the treated group with a significant (P < 0.05) reduction in sperm motility in the treated compared with control. The sperm density of treated and control were 14.5 x 106 /ml and 20.5 x 106 /ml respectively. However, there were also no significant difference in the relative testicular weight and sperm density of treated from that of the control respectively. Thus, it was concluded that BLCO ingestion is spermatotoxic in the adult male Swiss mice

This study assessed the effects green leaf tea extract on male reproductive function of male albino wistar rats. Twenty rats weighing between 150 250g, grouped into 4 of 5 rats each, were used for the research that lasted for four weeks. Group I, the control group, received normal rat chow and water ad libitum. The three test groups II IV, received 2.5gm 100ml 0f water, 5gm 100ml of water, 7.5gm 100ml of water of green leaf tea extract given via oral administration with normal rat food and water for four weeks. Blood was collected via ocular puncture and serum was assayed for testosterone levels. Semen was also analyzed for sperm motility and sperm count. The testicular weight was recorded and net body weight gain was also recorded. The study showed significant decrease in net body weight gain and testicular weight. It has been shown that the reduction of body weight after application of green tea extract may be due to inhibition of catechol O methyl transferase transferase COMT enzyme by epigallocatechin gallate EGCG of the green tea. The study also showed significant decrease in sperm motility and sperm count. It also showed a significant decrease in testosterone levels. In conclusion, green leaf tea extract had a negative effect on male reproductive function and its use as a daily tea should be curtailed. Okonkwo, C. O. J | Maduka, S. O | Akude Harrison | Mmaju, C.

Abstract— In ovo studies on the effect of 1,3,5, ppm Bioneem (0.03%) formulation on Biochemical aspect of chick embryo revealed that there was dose dependent total protein reduction in 96 hrs old embryo (treated at 24 hrs) as compared to the control. Also there was reduction in total protein concentration Liver, Brain and Heart of 15 day old chick embryo (treated with Bioneem at 96 hrs. stage) as compared to that of control. Protein carbonyl concentration of 96 hrs old embryo (treated at 24 hrs with Bioneem) and that of Liver, Brain and Heart of 15 day old chick embryo (treated with bioneem at 96 hrs) increased in dose dependent manner. Most affected organ was Liver and least affected organ was Heart. Blood analysis of 15 day old chick embryo (treated with Bioneem at 96 hrs) showed increased level of Blood urea, LDH, SGOT, SGPT, while Serum alkaline phosphatase and serum cholesterol were decreased in dose dependent manner as compared to the control. Thus Bioneem though ecofriendly pesticide can adversely affect vertebrate non target organisms and therefore should be carefully used in pest management programs.

ABSTRACT- Objective: In this experiment adult male albino rats were treated with 50% ethanolic extract of Tephrosia
purpurea fruits at the dose levels of 50, 100 and 200 mg/kg body weight for 60 days, to evaluate antifertility effects in
search of a reversible male contraceptive agent from medicinal plants.
Materials and Methods: Body and organs weight of all treated animals was recorded, blood and serum were analyzed for
hematological indices and clinical biochemistry. To observe effects on reproductive system of animal’s protein, fructose,
sialic acid, ascorbic acid, and glycogen contents were estimated in their testes and sex accessory organs. The treated male
rats were mated with proestrous females and sperm motility, sperm density was determined and FSH, LH and testosterone
hormones were measured to evaluate the effects on fertility. For histopathological observation testes were fixed in Bouin's
fluid, sections were cut at 6 μ and stained with Harris's Haematoxylin and eosin.
Results: Analysis of blood and serum revealed no significant effect after 60 days of the extract treatment. Body weight of
the extract treated rat had no significant alteration, whereas the weight of reproductive organs was decreased significantly
as compared to animals of control group. Protein, sialic acid, fructose contents and level of LH and testosterone hormones
was decreased significantly after treatment in extract treated rats as compared to control.
Conclusions: The fertility, sperm density and motility were declined significantly in rats treated with the ethanolic extract
of Tephrosia purpurea fruits. It is concluded that it might be due to androgen inhibition effects.

One of the testes' primary functions is to produce the haploid germ cells needed for sexual reproduction. Good vitality can be achieved through a healthy biological pattern and require lasting persistence throughout a productive male's life. This study aims to detect protein expression in rats' testes after being treated with ethanol Fenugreek seeds. As many as 32 male rats (Rattus norvegicus), aged 2-3 months (250-300 g) without anatomical abnormalities were used as experimental animals. They were divided into four groups: P0 as a control group was treated with normal drinking water, while groups of P1 to P3 were given 500, 1000, and 1500 mg kg-1 body weight/day of ethanol extract from Fenugreek seeds. The experiment of testicular protein expression was conducted with Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). The testes data were analyzed by One-way Analysis of Variance (ANOVA) and the Duncan Mean Range Test. The study concluded that Fenugreek's effect is believed to have an inducing impression on protein synthesis in the cells making up the testes. Besides, body weight, body weight gain, testicular weight, and testicular protein showed no significant difference (P> 0.05).

Abstract— Agave sisalana (sisal) is a monocotyledonous plant of great economic interest because it is a source of hard fiber in semi-arid areas. It has also been widely used by rural smallholders for animal feed in several countries. The toxic effects of plant on the animal reproduction are unknown. Then, the study investigated the possible side effects of different extracts derived from the processing of sisal leaves on the reproductive organs weight and testicular tissue of adult rats. The animals were treated with the extract obtained by acid hydrolysis (100 mg/kg body weight– b.w.; EHA/100), dry precipitate extract (250 and 500 mg/kg b.w.; EPS/250 and EPS/500), hexane extract (50 and 100 mg/kg b.w.; HEX/50 and HEX/100) or distilled water (Control group). Treatments were performed daily for 30 consecutive days, oral route (gavage) a single time daily. The results showed that in the group treated with EHA/100 extract only the weight of the seminal vesicles has been changed, but in the EPS/250, EPS/500, HEX/50 and HEX/100 groups there was significant increase (p<0.05) in the testes, epididymides and seminal glands weight, in comparison to the control group. All groups treated with the different extracts showed histopathological changes in the testes, characterized mainly by depletion of seminiferous epithelium, detachment of immature germ cells, scarcity sperm in the tubular lumen and interstitial hemorrhage, which occurred in a dose-independent manner in EPS and HEX groups. In conclusion, the different extracts of A. sisalana changed the reproductive organs weight and were promoters from gonadotoxic effect in rats.
In recent years as a result of the observation that the toxic effects of boron and its
products have increased intensive studies have been initiated in our country and in the world
regarding its effects, especially in the central nervous system, digestive system and reproductive
system. The aim was to determine the histopathological changes caused by boric acid in rat testis,
liver, kidney and brain tissues by light microscopy after oral administration of toxic dose of acute
boric acid.

Twenty sexually matured (24 weeks old) healthy Harco cocks were used to determine the effect of Gonadotrophin (Diclair®) on haematology and serum biochemistry. The cocks were divided into 4 treatment groups of 5 cocks per group identified as T1 (control) administered with 1ml physiological saline, T2, administered with 6.75i.u Diclair® and T4, administered with 20.25i.u Diclair®, with one cock per replicate in a completely Randomized Design (CRD). The injections were dividedinto three doses each and administered intramuscularly in the thigh for three consecutive days. One week after Diclair® treatments, five birds from each group were bled from the wing veins for haematology and serum biochemistry. Results of this study showed significant differences (P<0.05)>0.05) among the treatment groups. Basophils were not detected among the treatment groups. The results further showed significant differences (P<0.05)>0.05) among the treatment groups. However, the values were within the normal ranges, indicating that Diclair® had no deleterious effect on these parameters.

The leaf of lakum (Cayratia trifolia (L.) Domin.) contains compounds that are expectedly antihyperlipidemic. This study aims to determine the liver histological response to the lakum leaf extract and its effect on the levels of SGOT and SGPT in hyperlipidemic male rats (Rattus norvegicus). The male Wistar rats were randomly divided into 4 treatment groups. P0 was a group of rats that were given standard feed, P1 was a group that were fed with high fat diet, P2 was a group that were fed high fat diet and lakum leaf extract with a dose of 40mg/200g BW (body weight)/day, and P3 was a group were fed high fat diet and simvastatin at a dose of 0.18mg/200g BW/day. High fat diet was given for 30 days, whilst treatments were implemented for 28 days. The histological descriptions showed that the hepatocyte cell repair occurred in the treatment group that was given lakum leaf extract but there were no significant differences in liver weight as well as SGOT and SGPT levels. Lakum leaf extract can be used as an antihyperlipidemic agent whilst maintaining the histology of hepatocytes and would not interfere with the liver function of the hyperlipidemic male rats.

Increasing concern has been expressed about the declining sperm count of humans and the potential environmental effects of both synthetic and natural estrogenic endocrine disruptors (EEDs) on human reproductive health in the last few decades. However, due to paucity of knowledge, we evaluate the chronic reproductive toxicity of sesame phytoestrogenic lignans on the male Sprague Dawley (SD) rats’ testis. Thirty adult male SD rats weighing 150-200g were divided into three groups. Two treated groups received a daily dose of aqueous leaves extract of Sesamum radiatum at 14.0 mg/kg bw and 28.0mg /kg bw respectively via gastric gavage, while equal volume of normal saline was administered to the control group for six weeks. Seminal analysis and hormonal assay study were analyzed using SPSS software and P< 0.05 was considered statistically significant. The results showed significant (P< 0.05) body weight gains observed in all the animals with significant (P< 0.05) weight increase in their raw testicular weights compared to control. The relative testicular weight per 100g bw was significantly (P< 0.05) higher in control than treated. However, theweight gain was dose related with a reversal in their relative testicular weight. The cauda sperm count including the motility and morphology of the treated were significantly (P< 0.05) higher than control in a dose related manner. In addition, significant (P > 0.05) increases in testosterone and a significant decrease in FSH in the high dose (treated) compared to control. Sesame phytoestrogenic lignans improves spermatozoa quality in a dose related manner.

The results further showed significant differences (P<0.05)>0.05) among the treatment groups. However, the values were within the normal ranges, indicating that Diclair® had no deleterious effect on these parameters.
Liver Histological Response of Hyperlipidemic Male Rat (Rattus norvegicus) to...AI Publications
The leaf of lakum (Cayratia trifolia (L.) Domin.) contains compounds that are expectedly antihyperlipidemic. This study aims to determine the liver histological response to the lakum leaf extract and its effect on the levels of SGOT and SGPT in hyperlipidemic male rats (Rattus norvegicus). The male Wistar rats were randomly divided into 4 treatment groups. P0 was a group of rats that were given standard feed, P1 was a group that were fed with high fat diet, P2 was a group that were fed high fat diet and lakum leaf extract with a dose of 40mg/200g BW (body weight)/day, and P3 was a group were fed high fat diet and simvastatin at a dose of 0.18mg/200g BW/day. High fat diet was given for 30 days, whilst treatments were implemented for 28 days. The histological descriptions showed that the hepatocyte cell repair occurred in the treatment group that was given lakum leaf extract but there were no significant differences in liver weight as well as SGOT and SGPT levels. Lakum leaf extract can be used as an antihyperlipidemic agent whilst maintaining the histology of hepatocytes and would not interfere with the liver function of the hyperlipidemic male rats.

Sesame radiatum Phytoestrogens Stimulate Spermatogenic Activity and Improve S...lukeman Joseph Ade shittu
Increasing concern has been expressed about the declining sperm count of humans and the potential environmental effects of both synthetic and natural estrogenic endocrine disruptors (EEDs) on human reproductive health in the last few decades. However, due to paucity of knowledge, we evaluate the chronic reproductive toxicity of sesame phytoestrogenic lignans on the male Sprague Dawley (SD) rats’ testis. Thirty adult male SD rats weighing 150-200g were divided into three groups. Two treated groups received a daily dose of aqueous leaves extract of Sesamum radiatum at 14.0 mg/kg bw and 28.0mg /kg bw respectively via gastric gavage, while equal volume of normal saline was administered to the control group for six weeks. Seminal analysis and hormonal assay study were analyzed using SPSS software and P< 0.05 was considered statistically significant. The results showed significant (P< 0.05) body weight gains observed in all the animals with significant (P< 0.05) weight increase in their raw testicular weights compared to control. The relative testicular weight per 100g bw was significantly (P< 0.05) higher in control than treated. However, theweight gain was dose related with a reversal in their relative testicular weight. The cauda sperm count including the motility and morphology of the treated were significantly (P< 0.05) higher than control in a dose related manner. In addition, significant (P > 0.05) increases in testosterone and a significant decrease in FSH in the high dose (treated) compared to control. Sesame phytoestrogenic lignans improves spermatozoa quality in a dose related manner.

Development of novel natural dietary adjunct/agent with significant therapeutic effects on metabolic disease conditions such as obesity and heart disease raises concern in recent times. We studied chronic toxicity of the combined active ingredients present in the sesame leaves and their interaction on the fasting serum lipid profiles with their ratios in thirty adult male non-obese Sprague Dawley (SD) rats. Such that, both treated groups received 14.0 and 28.0 mg/kg body weight doses of aqueous leaves extract of Sesamum radiatum respectively on a daily basis via gastric gavage, while, the control received equal volume of normal saline daily for six weeks. Significant (P < 0.05) weight loss observed in the treated groups was associated with significant (P < 0.05) reductions in both serum cholesterol and triglycerides (TG). The effect on the serum lipoprotein cholesterol components and ratios were significant in a dose related manner, such that increase in HDL accompanied a corresponding decrease in both LDL and LDL/HDL ratio. In addition, to increased in TG/HDL ratio. However, no significant differences in the relative reduction level of VLDL and triglycerides in the treated groups were found compared to control. Thus, LDL/HDL ratio is significantly a better indicator than the TG/HDL ratio in assessing the impact of sesame treatment with evidence of weight loss and hypolipidaemia especially in hypertensive heart diseases.

This study was carried out to evaluate the effect of ethanolic leaf extract of Sida acuta on the micro-anatomy of the liver and some biochemical parameters in adult Wistar rats. Thirty rats weighing between 140-180g were assigned to three groups (A, B and C) with ten animals each. Group A served as the control while groups B and C served as the experimental groups and received 100mg/kgbw and 200mg/kgbw of the extract respectively for fourteen days. All the animals were sacrificed after fourteen days. Blood was collected by cardiac puncture for biochemical analysis of serum liver enzymes s The liver was removed, preserved and processed for paraffin sections and hematoxylin and eosin (H&E) staining. The animals in the control group showed normal histological and biochemical parameters. Conversely, animals that received 100mg/kgbw of the extract showed slight difference in their hepatic cyto-architecture while animals that were administered with 200mg/kgbw of the extract revealed distorted morphological feature showing shrunken sinusoid and dilation of the central vein suggesting that the extract has adverse effect on the morphology of the liver. Results of the serum liver enzymes of animals treated with 100mg/kgbw and 200mg/kg revealed significantly decreased values of AST, ALP and ALT (P <0.05) relative to the control. From the result of this experiment, it is concluded that administration of ethanolic extract of Sida acuta leaves may be toxic to Wistar rats at the doses administered.
Carcass, Organ Weights and Histo-morphology of Internal Organs of Sows Fed Fe...Premier Publishers
Fresh cassava peels were subjected to submerged fermentation, sundried for 3-5 days and also subjected to proximate analysis. Fermentation reduced cyanide and improved crude protein. A group of 27 weaner gilts (Largewhite x Duroc), aged 8-9 weeks and weighed 10.61±0.27kg were fed fermented cassava-peels-based-diets. They were allotted to three treatments comprising T1 (control), T2 (fermented CPM) and T3 (fermented CPM + enzyme) in a completely randomized design and fed for 22 weeks. Data on carcass and some visceral organs weights were subjected to analysis of variance and means separated using Duncan’s Multiple Range Test. Histo-morphology on the organs was conducted. The dressing percentages were 66.53, 60.25 and 64.11% for T1, T2 and T3 respectively whereas the head, heart, lungs and kidney were the weightiest for T1, the stomach/intestine for T2 and the liver and spleen for T3 while the histo-morphology of T1 sows were all normal except for mild architectural deviation in the duodenum and ileum. Histo-morphological changes were observed in the ileum and duodenum of T2 and T3. It is therefore recommended that fermented peels be supplemented with enzyme for improvement in dressing percentage and watch-out for pathological lesions in the visceral organs.
Biochemical and histological changes associated with methanolic leaf extract ...Open Access Research Paper
This study examined the biochemical and histological changes associated with methanolic leaf extract of Gongronema latifolium in acetaminophen-induced hepatic toxicity in wistar albino rats. The serum liver enzymesALT, AST and ALP decreased significantly (p<0.05) in the test animals treated with 600mg/kg of the leaf extract. Protein concentration increased significantly (p<0.05) in the test animals treated with 600mg/kg of the leaf extract.The effect of the G. latifolium leaf extract seems to be dose dependent on the liver enzymes and protein concentration measured. The results showed that acetaminophen-induced hepatic toxicity in the wistar albino rats as observed in the negative control was reversed with the administration of the leaf extract of Gongronema latifolium (in groups 3, 4 and 5) in the test animals. The histological analysis of the liver showed that the extract had a normalising effect on the effected liver. These results indicate that the leaf extract of Gongronema latifolium exhibits biochemical and histological changes and can be used against some hepatic inflammations.

Intensive studies on extracts and biologically active compounds isolated from medicinal plants have doubled in the last decade worldwide. However, as a result of paucity of knowledge and folkloric claim on the effectiveness of sesame leaves in infectious disease treatments, we aimed to determine the synergistic antimicrobial activity of essential oils and lignans present in the crude leaves extracts of Sesame radiatum and Sesame indicum. Ethanolic, methanolic and aqueous extracts of both leaves were studied for their in-vitro synergistic antimicrobial activity against both Gram positive and Gram negative micro-organisms, and Yeast using Agar diffusion method. The GC-MS phytochemical screening of methanolic extract showed that the major compounds in essential oils are of carboxylic acids and phenolic groups especially, the most potent antioxidants known to man like sesamol, sesamolin and sesamin among others. Methanolic and ethanolic extracts have broad spectrum antimicrobial effect against all the tested pathogenic micro-organisms except Streptococcus pneumoniae and Staphylococcus aureus respectively, while the aqueous extract exhibited inhibitory activity on Staphylococcus aureus, Streptococcus pneumoniae and Candida albicans. The result confirmed the folkloric claims of the antimicrobial effectiveness of locally consumed sesame leaves extracts especially against bacterial and common skin infection in many areas of Nigeria .

Concern about the rising prevalence of antibiotics-resistant strains of pathogenic microorganisms has been expressed in the last three decades. However, intensive studies on extracts and biologically-active compounds isolated from medicinal plants have also doubled in the last decade. As a result of paucity of knowledge and folkloric claim on the leaves effectiveness in infectious disease treatments, we aimed to determine the antimicrobial activity of essential oils and lignans present in the crude Sesame radiatum leaves extracts. Ethanolic, Methanolic and Aqueous extracts of Sesame radiatum leaves were studied for their in-vitro antimicrobial activity against both Gram positive and Gram negative micro-organisms and Yeast using Agar diffusion method. The GC-MS phytochemical screening of methanolic extract showed the presence of carboxylic acids and phenolic groups in essential oils especially some of the most potent antioxidants like Sesamol, Sesamolin and Sesamin. Both the methanolic and ethanolic extracts have broad spectrum antimicrobial effect against all the tested micro-organisms except Streptococcus pneumoniae, Candida albicans and Staphylococcus aureus respectively, while the aqueous extract exhibited no inhibitory effect on Staphylococcus aureus and Streptococcus pneumoniae except on Candida albicans. The result confirmed the folkloric claims of the antimicrobial effectiveness of locally consumed Sesame leaves extracts especially against bacterial and common skin infection in many areas of the Country (Nigeria).
The negative impacts of adolescent sexuality problems among secondary school ...lukeman Joseph Ade shittu
This study was conducted to focus on the negative health outcomes related to sexual behaviour in adolescents and young adults attending public school in the Oworonshoki region of Lagos, Nigeria, Africa. Since, there is a relative dearth of knowledge on adolescents who face unique and challenging economics, health and education problems in our society. Data on the socio-demographic characteristics, prevalence and knowledge towards STD including HIV/AIDS, prevalence of sexual abuse practice/sexual behaviour, family planning awareness and acceptance including abortion practice were sorted out using self structured questionnaires and administered to 60% of student’s population using a stratified random sampling technique. 55.8% lived with both parents. While, 50.3% of the mothers had basic secondary school qualifications, 72.4% of them are traders. 61.5% had sex education were from misinformed friends/peers while 51% had no basic knowledge about sexual behavioral practice and attitude towards STDs/AIDS (HIV). STD has a prevalence of 34 and 41% of boys used condoms for preventing STI/HIV transmission and unwanted pregnancies. One out of every five sexually active teenagers has experienced forced sex, especially among the circumcised girls who were more sexually active than the uncircumcised girls. 60% of girls between ages of 12 and 18 years had more than one unsafe abortion with severe vaginal bleeding (haemorrhage) as the chief complication. However, 65% of the girls did abortion for fear of leaving school and financial hardship as the reasons.
STEREOLOGICAL EVIDENCES OF EPITHELIAL HYPOPLASIA OF SEMINIFEROUS TUBULES INDU...lukeman Joseph Ade shittu
BACKGROUND: Anabolic-androgenic steroid compounds are one of the most widely abused drugs by athletes and muscle builders with the goal of improving performance/ability, appearance, or muscle mass. In addition, these steroids are widely used in the treatment of male infertility and subfertility. However, increasing concern has been shown that these compounds may not only offer unappreciable benefits to infertile and subfertile males, but might have deleterious effects on both human and animal physiology and sperm quality. There is a dearth of knowledge on the structural and quantitative changes of the testis secondary to this group of compounds. Objective: The present study was carried out to evaluate the effects of mesterolone (proviron), an anabolic-androgenic steroid, on some of the histomorphometric and stereological parameters of the seminiferous tubules in Sprague-Dawley rat. Materials and Methods: Two groups of 10 adult male rats were used. The treated group was given 0.06 mg/kg body weight/day of mesterolone by gavage for six weeks while the control group received equal volume of 0.9% normal saline per day. Five µm of uniformly random serial sections of the processed testicular tissues were analyzed using un-biased stereological and histomorphometric studies. Results: The results showed that the percentage mean volume density of both the tubular lumen and epithelial height increased by 35% (p< 0.05) and decreased by 50% (p<0.05), respectively compared to the control. mesterolone also caused a significant decline in sperm concentration. Conclusion: Mesterolone produces epithelial hypoplasia in the testis post continuous management.

Concern about the rising prevalence of antibiotics resistant strains pathogenic micro-organisms has been expressed in the last three decades. However, intensive studies on extracts and biologically active compounds isolated from medicinal plants have also doubled in the last decade. Ethanolic and aqueous extracts of Sesame radiatum leaves were studied for in-vitro antimicrobial activity using agar diffusion method. The gas chromatography-mass spectrometry (GC-MS) phytochemical screening showed the presence of essential oils mainly the phenolic and carboxylic acids groups. The ethanolic extract mildly inhibited the growth of Streptococcus pneumoniae and Candida albicans, while there was no inhibitory effect on Staphylococcus aureus, Pseudomonas aurogenosa and Escherichia coli. However, aqueous extract exhibited no inhibitory effect on all the five tested micro-organisms

Anabolic-androgenic steroid compounds are one of the most widely abused drugs by athletes and muscle builders with the goal of improving performance/muscle mass. However, increasing concern has been expressed because these compounds not only offer unappreciable benefits to infertile and subfertile males, but also might have deleterious effects on both human and animal physiology including sperm quality. In addition, there is the conflicting outcome of AAS usage in the clinical settings with its attendant reduced spermatogenesis and hypopituitarism in patient management. Hence, we aim to evaluate the effects of mestorolone, an anabolic-androgenic steroid, on the histomorphometry of seminiferous tubules with serum hormonal and seminal analyses in adult male Sprague-Dawley rat. Twenty adult male Sprague dawley rats divided into two groups of 10 each. The treated group received 0.06 mg/g body weight/ day of mesterolone (proviron) by oral gavage for six weeks while the control group received equal volume of 0.9% normal saline per day. SPSS analysis of data generated with P< 0.05 considered statistically significant. The result showed significant (P< 0.05) body weight gain in all the animals. However, both the raw testicular weight and relative testicular weight per 100 g bwt was significantly (P< 0.05) higher in control than treated. The mean sperm count significantly decreased by 28% (P< 0.05) and the motility reduced significantly by 56% (P< 0.05) in the treated compared to control. In addition, both FSH (follicle stimulating hormone) and T (testosterone) of the treated were significantly lowered by 73% (P< 0.05) and 63% (P< 0.05) respectively compared to the control. The use of mesterolone is with caution and short intermittent therapy is desirous for better semen quality and improved overall fertility.

This study was designed to assess the convergent validity of the professional anatomy (a multifaceted examination) with other markers of success (the various interactive assessment components of the curriculum) in determining the overall performance of third-year medical students. The aim was to isolate area of academic weakness among the students and to readjust the curriculum content to balance the weakness. A total of 66 third year medical students with records of their grades in the various assessments criteria were analyzed. Parameters on the average End-in course assessment, Short Essays Question (SEQ), Multiple-Choice Questions (MCQ), and Practical (Steeple-chase) were considered. The Practical significantly correlated with overall performance (r = 0.89, P< 0.01). The Practical, MCQ, SEQ and End incourse showed an overall rank order of relative performance in assessment tasks and therefore indicate that, in general, students performance in the Professional examination was better than in the End-incourse examination.

Concern has been expressed about the motivational impact of neuro-anatomy award/prize in determining the overall student performance in the final professional anatomy examinations by comparing it with the result outcome of a high stake examination like neuro-anatomy incourse examination using the concept of convergent validity. A total of 57 third year medical students with the records of their grades/scores (Mean ± SD) in the various assessments criteria, were analyzed. In this study, the neuro-incourse examination was consistently a high predictor (r = 0.80; P<0.01)><0.01>< 0.01 respectively). However, the neuro-incourse examination tests students’ performance in a relatively difficult module and was found to be consistently correlated and highest when compared with the overall professional examination as a result of student motivation.

The development of a new dietary adjunct with a novel natural antioxidant impact on diabetes mellitus with prevention of its long term deleterious effect on the male fertility in general has been increasingly expressed in recent time. Hence, we aim to evaluate the effects of aqueous extract of Sesame radiatum leaves on adult male Sprague Dawley rats’ testis using unbiased stereological, biochemical and hormonal studies. Thirty adult male rats were divided into three groups of 10 rats each. The treated groups; 1 and 2 received 28.0 and 14 mg/kg bwt of aqueous extract of sesame leaves via oral garvage, respectively, while the control group received equal volume of 0.9% (w/v) normal saline per day for 6 weeks. Serum follicle-stimulating hormone (FSH), testosterone and blood glucose were assayed. In addition five microns of uniformly random transverse sections of processed testicular tissues were equally analyzed using an un-biased stereological study. The result showed that the mean percentage volume fractions (Vf) of epithelial cells and lumen of the testis were 76% (P<0.05)><0.05),>0.05) higher than the control in a dose related manner. Serum testosterone and FSH were significantly higher and lower, respectively, in the high dose sesame when compared to control. Sesame leaves intake improved glucose profile and testicular parameters in a dose related manner via possible improved insulin activity on the cells with a stimulatory impact on sperm production. This also confirmed its folkloric claims.

This study was designed to assess the impact of swim up preparation of both fresh and cryopreserved sperm on the pregnancy outcome in a private fertility centre in Lagos. A cross-sectional prospective analysis of 34 asthenozoospermic semen samples of men whose wives were undergoing assisted reproduction was studied. The basic semen parameters comprising of the volume, count, and motility of the sperm before and after swim up preparations with pregnancy outcome were measured. For fresh semen (n = 28, mean age = 37.0 ± 1.1 years, mean volume = 2.16 ± 0.1 ml), the sperm count decreased significantly (p<0.01)><0.01)><0.01)><0.01) from 25.1 ± 4.01 to 32.8 ± 6.18%. The pregnancy outcome of cryopreserved was 30%. The pregnancy outcome was higher with fresh than the cryopreserved semen. However, the motility was a significant indicator for the successful outcome. Swim up procedure improve the motility of both cryopreserved and fresh semen with a better pregnancy outcome in this study.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Sesame plant is one of the richest food source of lig-
nans, a major type of phytoestrogens known to man sin-
ce the dawn of civilization (Thompson et al., 1991) and is
increasingly being incorporated into human diets because
of its reported health benefits. However, sesame lignans
such as sesamin, episesamin, sesamolin, and -tocophe-
rol isolated from Sesamum indicum and Sesamum radia-
tum seeds among other species have been implicated as
having anti-tumorigenic (Hirose et al., 1992), estrogenic
and/or anti-estrogenic (Collins et al., 1997; Shittu, 2006)
and antioxidant (Kang et al., 1999; Hou et al., 2004; Shit-
tu, 2006) properties. Moreover, the ROS scavenging
moiety of sesame lignans may contribute important com-
ponents which prevent body cells from the free radical
injury (Jeng et al., 2005).
Sesame is reputed in folk medicine in Africa and Asia.
All parts of the plant are useful.
Sesame plant especially the seed, oil and leaves are
consumed locally as a staple food by subsistence far-
mers in South-West and Middle Belt areas of Nigeria (Ak-
pan –Iwo et al., 2006) and this may account for the high
fecundity among the adult male population in these areas
(Shittu, 2006). In the South-Western Nigeria, decoction of
the leaves is used for the treatment of bruised or erupted
skins, catarrh and eye pains. However, leaves decoction
has been found to have antimicrobial effects (Shittu et al.,
2006; Bankole et al., 2007).
The spermatocytes released from the testis, upon rea-
ching the epididymis will undergo additional physiological
maturation (capacitation) and gain fertilizing capacity and
motility. However, sperm maturation in the epididymis
involves various morphological and biochemical changes
with the initiation of progressive motility and acquisition of
fertilizing ability. The acquisition of sperm motility is a key
element of epididymal sperm maturation (Orgebin-Crist,
1967), which occurs in the microenvironment provided by
the epididymal secretory products such as Sialic acid,
acetyl carnitine, Glyceryl phosphoryl choline (GPC) amo-
ng others, to help maintain the osmolarity of epididymal
luminal fluid (Wales et al., 1966), thereby serving as sta-
bilizer of the spermatozoal membrane (Scott et al., 1963),
and playing a vital role in the metabolism of spermatozoa
after capacitation (Mitra and Chowdhury, 1994).
However, estrogen (E2) has been implicated to regula-
te ions transport and luminal fluid reabsorption in the
efferent ductules of the male. Since, most of the testicular
fluid (about 96%) is reabsorbed by the non-ciliated cells
in the efferent ductules (Clulow et al., 1998) and without
this re-absorption, the sperm will remain diluted and inca-
pable of maturation in the epididymis and as such any
blockage in the estrogen receptor’s function may result in
infertility. Moreover, estrogen is responsible also for ma-
intaining the differentiated epithelial morphology through
an unknown mechanism. Thus, estrogen or its receptor is
important for normal functioning of the male reproductive
tract in numerous species (Hess and Carnes, 2004).
As a result of paucity of knowledge, we aim to carry out
this study on the chronic toxicity effect of aqueous extract
of S. radiatum leaves on the adult male Sprague Dawley
(SD) rat epididymis using histomorphometric study and
hormonal assay.
MATERIALS AND METHODS
Collection of plant materials
Sesame plants (S. radiatum, Schum and Thonn - Pedaliacaea fami-
ly) were bought from a vendor in Agege market, Lagos. The plant
was authenticated by the herbarium section of Forestry Institute of
Research (FRIN) with FHI # 107513 on the 5th
of August, 2005 (Shi-
ttu et al., 2006). Voucher specimens were deposited in Botany Dep-
artments of University of Ibadan and Lagos State University, res-
pectively.
Preparation of extracts
The leaves of the plants were air dried for 2 weeks and powdered.
For the preparation of the aqueous extraction of sesame leaves,
100 g of the powdered leaves was added to 1.0 litre of distilled wat-
er at a ratio of 1:10 in a beaker and allowed to boil to boiling temp-
erature after intermittent stirring on a hotplate for one hour. The
decoction was filtered into another clean beaker using a white sieve
clothing material and the filtrate evaporated at 50o
C to dryness in a
desiccator to produce a black shinning crystal residue form with a
yield of 83% w/w of the extract. The crude extract was kept in the
refrigerator (4o
C) before being reconstituted and used for the in vivo
study.
To prepare the ether extracts, 100 g of the powdered leaves
were extracted with 500 ml of 40% diethyl ether for 72 h with Sox-
hlet equipment using modified method of Alade and Irobi (1993).
Phytochemical screening using gas chromatography-mass
spectral
Gas chromatography of crude ether extract of sesame leaves was
performed using a Hewlett Packard GCD system (model 6890),
equipped with a flame ionization detector and injector MS transfer
line temperature maintained at 230°C respectively as described in
our previous study (Shittu et al., 2006). Compound identification
was accomplished by comparing the GC relative retention times
and mass spectra to those of authentic substances analyzed under
the same conditions, by their retention indices (RI) and by com-
parison to reference compounds (Shittu et al., 2006).
Animal experiment
Thirty mature and healthy adult male Sprague Dawley rats weighing
120 to 216 g were procured from Ladoke Akintola University, Col-
lege of Medicine, Ogbomosho and housed in well ventilated wire-
wooden cages in the departmental animal house. They were main-
tained under controlled light schedule (12 h light and 12 h dark-
ness) at room temperature (28o
C) and with constant humidity (40 -
50%). The animals were allowed to acclimatize for a period of 7
days before treatment during the experiments. During this period
they were fed with standard rat chows/pellets supplied by Pfizer
Nigeria Limited and water ad libitum. Individual identification of the
animal was made by ear tags.

The rats were randomly divided into three groups (A to C) compri-
sing of ten rats each. The group A served as the control while B
and C constituted the treated groups. The animals in group A recei-
ved equal volume of 0.9% (w/v) normal saline daily while group B
received aqueous extract of sesame leaves at 14.0 mg/kg body
weigh /day(half the group B dose). The animals in group C were
given aqueous extract of sesame at 28.0 mg/kg body weight/day
(twice the group B dose). All the doses were given via gastric gava-
ge (oro-gastric intubation) daily for a period of 6 weeks. All proce-
dures involving animals in this study conformed to the guiding prin-
ciples for research involving animals as recommended by the decal-
ration of Helsinki and the guiding principles in the care and use of
animals (American Physiological Society, 2002) and were approved
by the departmental committee on the use and care of animals. All
animals were observed for clinical signs of drug toxicity (such as
tremors, weakness, lethargy, refusal of feeds, weight loss, hair-loss,
coma and death) throughout the duration of the experiment.
The rats were anaesthetized at the time of sacrifice by being pla-
ced in a sealed cotton wool soaked chloroform inhalation jar bet-
ween 0900 and 1100 h done the following day after the termination
of the experiment following over night fasting of the animals. The
weights of the animals were taken weekly and before the sacrifice.
The epididymes were carefully dissected out, trimmed of all fat and
blotted dry to remove any blood. Their weights were noted and
volume measured by water displacement with the aid of a 10 ml
measuring cylinder. Later, the sizes (length and width) were recor-
ded by use of a sliding gauge (d = 0.1) before being fixed in freshly
prepared 10% formol saline solution. The fixed tissues were trans-
ferred into graded alcohol and then processed for 17.5 h in an
automated Shandon processor after which was passed through a
mixture of equal concentration of xylene. Following clearance in
xylene the sections were then infiltrated and embedded in molten
paraffin wax. Prior to embedding, it was ensured that the mounted
sections to be cut by the rotary microtone were orientated perpen-
dicular to the long axes of the epididymes. These sections were
designated “vertical sections”. Serial sections of 5 µm thickness
were cut, floated onto clean slides coated with Mayer’s egg albu-
min for proper cementing of the sections to the slides and were
then stained with haematoxylin and eosin as previously described
(Shittu, 2006).
Hormonal assay
The estimation of testosterone was carried out using the procedure
enclosed with the kit purchased from Amersham International Plc.
(UK) by ELISA technique as previously described (Shittu, 2006).
The inter- and intra-assay coefficients of variation for the testoste-
rone were <15%.
Statistical analysis
The weight data were expressed in mean ± S.D. (standard devia-
tion) while other data were expressed as Mean ± S.E.M (standard
error of mean). Statistical analyses were done by using the student
t-test and ANOVA as the case may be with input into SPSS 12
software Microsoft computer (SPSS, Chicago, Illinois). Statistical
significance was considered at P 0.05.
RESULTS AND DISCUSSION
The GC/MS showed the presence of essential oils mainly
the carboxylic phenolic groups such as (sesamol, sesa-
min) and other compounds such as thiazole, pyrroles,
disulphide, ketones and aldehyde (Shittu et al., 2006).
No obvious toxicity signs such as weakness, lethargy,
tremors, refusal of feeds, weight loss, hair loss, coma and
death were seen in any of the animals. However, most of
the animals exhibited calmness; improve appetite for food
and water and general sense of well-being, all through
the duration of the study. Evidence of significant (P <
0.05) weight gain was observed in all the animals. The
weight gain observed in the treated groups were dose
dependent such that weight gain in the high dose was
more than that in the low dose as observed in Table 1.
The epididymal weight increased significantly (P < 0.05)

in the high dose as compared to the low dose with no
significant weight difference in the relative epididymo-
somatic weight (weight/100 g body weight) of the high
dose compared to control. However, the low dose weight
was significantly lower as observed in Table 2. The epidi-
dymal lumens in the sesame treated were wider, fewer
with irregular tubular formation and significantly filled with
spermatocytes when compared to the control group whi-
ch are relatively numerous with smaller luminal sizes as
shown in the Figure 1.
There is significant (P > 0.05) increases in testosterone
level compared to control, however, the low dose was
also significantly different from the control as shown in
Table 3.
This is the first study, to our knowledge, to look at the
role of sesame lignans on the male reproductive tracts
after extensive literature review. There is increasing role
of sesame lignans research contribution to medicine.
However sesame, being rich in trace elements or mine-
rals, vitamins, antioxidant lignans (phytoestrogens), have
the ability of improving fertility potential of the male repro-
ductive tract but its mechanism of action need to be
elucidated in this study.
The beneficial effects derived from the high intake of
fruits and vegetables on the various metabolic disease
conditions (such as diabetes mellitus, obesity, heart dis-
eases and cancer), that may impact on one’s reproduc-
tive life may not be due to the effect of their well charact-
5. erized antioxidants, such as -carotene, vitamins C and E
only, but rather to some other antioxidants or non-antioxi-
dant phytochemicals or by an additive actions of the diff-
erent compounds present in foods (fruits and vegetables)
such as alpha-linolenic acid (poly unsaturated fatty
acids), various phenolic compounds (sesamin, sesamol)
and fibres, which are present in sesame leaves for exam-
ple (Shittu et al., 2006).
All the animals that were used in this study, irrespective
of their aggressive nature, exhibited calmness (non-aggr-
essive state) during treatment. More so, there was a
general state of well-being observed in all the animals
during the whole experimental period. This may reflect
the positive effect of some of the active agents present in
the plant on their neuropsychological and neuro-endo-
crine pathways. The sesame-treated rats showed signifi-
cant weight gain (P < 0.05, using ANOVA), unlike in other
studies where no significant difference in the animal wei-
ghts was observed (Awoniyi et al., 1997).
The relative epididymal weight difference is a reflection
of the site of action of the sesame estrogenic lignans whi-
ch may also be hormonally influenced. Since the efferent
ductile and epididymis of rats are rich in estrogens recap-
tors; α and sub-types (Hess et al., 1997; Hess and Car-
nes, 2004) just like any other part of the body such as
uterus and mammary glands among others (Williams et
al., 2000; Nie et al., 2002), any disruption of these
receptors as a result of abnormalities in the efferent
ductules or epididymis have been hypothesized to lead to
impairments of male fertility in mice (Hess, 1997; Hess
and Carnes, 2004). However, efferent ductile or epididy-
mis is also richer in androgen receptor, the site for action
of the testosterone (TT), dihydrotestosterone (DHT) and
probably estradiol (E2) (Oliveira et al., 2003).
Testosterone level in the high dose sesame was signi-
ficantly higher than the control and the low testosterone
level observed in the low dose group could be due to the
fact that some of the testosterone were aromatized to
estradiol and/or converted to dihydrotestosterone by the
aromatase and reductase enzymes present within the
epididymis. Moreover, Huang et al. (1987) demonstrated
that as little as 25% of normal testicular testosterone con-
centration is sufficient to support all stages of spermato-
genesis and that consistency in testosterone concentra-
tion is important for normal spermatogenesis to occur as
evidence by the low dose epididymal lumen with fuller
spermatocytes compared to control in the present study.
Moreover, sesame phytoestrogenic lignans will tend to
promote aromatization of testosterone to estradiol, such
that, the low dose sesame will make available less endo-
genous estradiol and compete less, although there is sy-
nergism at this level between the testosterone and estra-
diol to favour spermatogenesis. However, reverse is the
case for the high dose, which will cause more estradiol
production and compete more with dihydrotestosterone
for aromatization to occur in its favour if possible. The low
testosterone observed here is not as a result of destruct-
Shittu et al 323
tion of the Leydig cells but a reflection of the complex
hormonal interplay at the level of the hypothalamic-
pituitary-testicular axis.
Brown and Chakraborty (1992) have suggested that
agent like clomiphene will decrease the synthesis and/or
release of gonadotrophins such that decreased serum LH
(Luitenising Hormone) and testosterone concentration
(ng/ml) were found in male rats. However, low dose est-
radiol is also needed for spermatogenesis than high dose
as evidence in the present study.
Little is known about the mechanism of action of sesa-
me phytoestrogen lignans with antioxidative properties.
But, contrary to speculation that phytoestrogen disrupt
male reproductive development through mechanisms wh-
ich are independent of the estrogens receptors, in which
there is estradiol (E2)-induced transactivation of the and-
rogen receptor (AR) (Degen and Metzler, 1987). We are
able to demonstrate that sesame lignans has no negative
impact on the male reproductive tract through its binding
on the estrogen receptors but also modulate the activity
of the androgen receptor in the epididymis, thereby ultim-
ately influencing the hypothalamic-pituitary-testicular pa-
thway as evidence in this study.
In general, aromatase has not been found in rat testis,
efferent ductules, epididymis or vas deferens (Hess and
Carnes, 2004). However, various reports are found on
the epididymal presence of aromatase in human efferent
ductules and proximal epididymis (Carpino et al., 2004)
and cultured rat cells, (Wiszniewska, 2002).
We also hypothesized that the action of sesame on the
-estrogens receptors as an agonist is more pronounced
than that of the α-estrogens receptors with transactivation
of the androgen receptor together with its antioxidative
property have all contributed to enhancing spermato-
genesis with improve male fertility (through production of
quality spermatocytes) found in this study. However, stu-
dy is on to confirm this hypothesis further.
Conclusion
Sesame improve epididymal sperm reserve with larger
spermatocytes being produced in a dose related manner
as evidence in this study through a complex hormonal
interplay at the level of the male hypothalamic-pituitary-
testicular axis and estrogens receptors.
