It then covers evaluation of azoospermia including history, physical exam, hormonal assessment, imaging, and genetic testing to determine if the cause is obstructive or non-obstructive. For non-obstructive cases, pretreatment with gonadotropins may help. Surgical sperm retrieval techniques are discussed including micro-TESE which has a 50% success rate. Varicocele repair in non-obstructive azoospermia is also reviewed. The summary emphasizes improved evaluation and management options have increased treatment success rates for many azoospermic men.
This document discusses male infertility, including its causes, classification, investigations, and normal semen values. It covers pre-testicular, testicular, and post-testicular causes of infertility. Key tests include semen analysis, hormonal assessment, immunological tests, and genetic testing. The document also provides details on the process and interpretation of semen analysis, including sperm motility, morphology, and vitality.
The cause for infertility could be in the male or the female or both or neither-as in ‘Unexplained Infertility.’
Male infertility is usually caused by problems that affect either sperm production or sperm transport.
ROLE OF PATHOLOGIST IN DIAGNOSIS & MANAGEMENT OF DISEASEIra Bharadwaj
A pathologist plays two key roles in patient care: diagnosis of disease and management of disease. For diagnosis, the pathologist uses laboratory tests to confirm clinical diagnoses and determine the specific cause of disease. This informs evidence-based treatment. For management, the pathologist assesses treatment effectiveness through laboratory parameters and ensures safe blood transfusions when needed through the blood bank. As an example, a pathologist would diagnose and monitor the specific cause and treatment of a patient's anemia through hematological tests.
This document discusses primary immune deficiency diseases. It covers the general features, etiology, and types of congenital immune deficiencies including defects of B lymphocytes like X-linked agammaglobulinemia and common variable immunodeficiency. It also discusses defects of T lymphocytes including severe combined immunodeficiency. Other conditions mentioned include DiGeorge syndrome, Wiskott-Aldrich syndrome, and complement deficiencies. Multiple choice questions are provided to test understanding of these conditions.
Wet gangrene occurs due to venous obstruction leading to tissue ischemia and bacterial proliferation in moist tissues. It presents as soft, swollen, foul-smelling black tissue without a clear line of demarcation. Diabetic foot gangrene results from peripheral vascular disease, neuropathy, and infection facilitated by hyperglycemia. Dry gangrene occurs from arterial insufficiency and presents as a dry, shrunken black tissue with a well-demarcated border. Gas gangrene involves Clostridium bacteria producing tissue-damaging toxins and crepitus. Prompt surgical debridement and antibiotics are critical for treatment.
This document discusses cell injury, including its definition, types, causes, and pathogenesis. It defines cell injury as a change that occurs in a cell due to external or internal factors in its environment. There are two types of cell injury - reversible and irreversible. Reversible injury is when the cell is damaged but viable, while irreversible injury means the cell is nonviable. Common causes of cell injury include hypoxia, chemicals, infections, physical factors, and genetic factors. The pathogenesis of cell injury involves mitochondrial damage, disturbances in calcium metabolism, damage to cellular membranes, DNA and proteins. Reversible injury can progress to irreversible injury when ATP production ceases, cell membranes lyse, vital proteins are absent, and vital

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

ejaculated specimen by masturbation,
following 2-7 days of sexual abstinence
• Sample is collected in a clean wide mouthed
glass or plastic container or in a properly
washed dry condom.
• Sterile collection is needed for microbiology
examination & assisted reproductive therapy
[ART]
6. SAMPLE TRANSPORT
• Specimen should be delivered as early as
possible to the laboratory
• And not later than one hour after collection
• Sample should be maintained between
20-37 *c
7. GROSS EXAMINATION
The following normal features are present:
• Color: translucent whitish, grey white or
yellowish
• Volume : between 2.5 to 5ml
• Viscosity : viscous and falls drop by drop
• Reaction: alkaline with pH of more than 7.2
• Liquefaction : liquefaction occurs because of
presence of fibrinolysin. Normally occurs
between within 10-30 minutes
8. SEMEN VOLUME & ITS SIGNIFICANCE
Low semen volume
• Collection problems like loss of a fraction of the
ejaculate & partial retrograde ejaculation
• Obstruction of the ejaculatory duct
• Congenital absence of the vas deferens,
• Poorly developed seminal vesicles
• Androgen deficiency
High semen volume
• Active inflammation
9. SEMEN pH & ITS SIGNIFICANCE
pH less than 7.0 with low volume and low
sperm count:
• Ejaculatory duct obstruction or
• Congenital absence of the vas deferens
• Poorly developed seminal vesicles
High pH values provide little clinically useful
information.
11. MICROSCOPIC EXAMINATION
Motility
Method:
• Place a drop of liquefied semen on a clean glass
slide & cover with a cover slip
• Examine under the microscope – first low power
and then high power
• Assess at least 300 sperms
• Motile or non motile
• Progressive[PR] or non progressive motility[NP]
12. MICROSCOPIC EXAMINATION
Motility
Normal range:
• Within 1 hr – 70 – 90% motility
• 2 hrs – 40 - 70% motility
• 6 hours – 25 -50% motility
• The lower reference limit for total motility (PR
+ NP) is 40%
• The lower reference limit for progressive
motility (PR) is 32%
13. SPERM MOTILITY & ITS SIGNIFICANCE
• If motility is less than 50%; stain for viability [ eg
eosin] should be done to differentiate between
dead & viable non motile sperms
• Red dye accumulates in the head of dead sperms.
• Viable but immotile sperms are associated with
structural defects in the flagellum eg immotile
cilia syndrome [Kartagener syndrome-
bronchiectasis, situs inversus, sinusitis, infertility]
• Non-viable cells (necrozoospermia) may indicate
epididymal pathology
15. SPERM MOTILITY & ITS SIGNIFICANCE
• Temperature - sperm motility value will be
inaccurately low if the semen sample gets cold.
• ASTHENOZOOSPERMIA – sperm motility less
than 40%
• Test should be repeated under ideal
conditions to rule out laboratory error
16. SPERM MOTILITY & ITS SIGNIFICANCE
Causes of asthenozoospermia:
• Abnormal spermatogenesis
• Epididymal sperm maturation defect
• Abnormalities in transport
• Varicocele
17. MICROSCOPIC EXAMINATION
sperm count [concentration]
• Manual method: Using Neubauer’s Chamber
& WBC pipette
• Normal range: 40-140 million/ml
• Oligospermia : < 15-20 million/ml
• Azoospermia: no sperms
18. MICROSCOPIC EXAMINATION
Sperm concentration & total number
The terms “total sperm number” and “sperm
concentration” are not synonymous.
• Sperm concentration refers to the number of
spermatozoa per unit volume of semen
• Total sperm number refers to the total
number of spermatozoa in the entire ejaculate
and is obtained by multiplying the sperm
concentration by the semen volume.
19. MICROSCOPIC EXAMINATION
Sperm concentration & total number
• Lower reference limit for sperm concentration
is 15 million spermatozoa per ml .
• Lower reference limit for total sperm number
is 39 million spermatozoa per ejaculate .
20. SPERM COUNT & ITS SIGNIFICANCE
AZOOSPERMIA is total absence of sperms. Common
causes are:
Pretesticular causes
• Deficient gonadotropin secretion by pituitary
Testicular causes
• Undescended testis
• Maldeveloped testis eg Klinefelter’s syndrome
• Severe testicular damage eg mumps, radiation
Post-testicular causes
• Ductal obstruction at any level eg ejaculatory duct
21. SPERM COUNT & ITS SIGNIFICANCE
OLIGOSPERMIA is sperm concentration less than
15 million per ml. Common causes are:
Pretesticular causes:
• Hormonal imbalance (testosterone, luteinizing
hormone (LH), follicle-stimulating hormone
(FSH), or prolactin excess
• Long term illness such as diabetes &
hypothyroidism
• Excess estrogen & corticosteroids
22. SPERM COUNT & ITS SIGNIFICANCE
Testicular causes:
• Orchitis
• Radiation treatment to the testicles
• Diseases that can cause shrinking (atrophy) of
the testicles (such as mumps).
Post –testicular causes:
• Varicocele
23. MICROSCOPIC EXAMINATION
MORPHOLOGY
• Prepare a thin smear of liquefied semen &
stain it with Romanowsky Stain, Pap Stain or H
& E Stain after fixing it in 95% ethanol
• Examine under oil immersion and look for
normal and abnormal form of sperms, RBCs,
WBCs & epithelial cells.
• Normally 60% sperms are of normal
morphology
24. MICROSCOPIC EXAMINATION
SPERM MORPHOLOGY
Spermatozoa is about 60 um in length, it consist of :
• Head &neck,
• Middle piece (midpiece),
• Tail and
• Endpiece, which is difficult to see with a light
microscope, so practically sperm consists of three parts
• Head and neck & midpiece and tail.
• For a spermatozoon to be considered normal, all three
parts should be normal.
• All borderline forms should be considered abnormal.
26. SPERM MORPHOLOGY & ITS SIGNIFICANCE
HEAD OF SPERM
• The head should be smooth, regularly contoured
and generally oval in shape.
• It measures 4-5um in length & 2.5-3.5 um in
diameter
• There should be a well-defined acrosomal region
comprising 40–70% of the head area
• Neck is short & connects head to midpiece
• Abnormalities are small, large, tapering & tear
drop shaped heads.
• Large vacuoles in the head are also abnormal
27. SPERM MORPHOLOGY & ITS SIGNIFICANCE
MIDPIECE OF SPERM
• The midpiece is 5-7um in length
• It should be slender, regular and about the same
length as the sperm head.
• The major axis of the midpiece should be aligned
with the major axis of the sperm head.
• Residual cytoplasm is considered an anomaly
only when in excess, i.e. when it exceeds one
third of the sperm head size
• Abnormalities are thick, thin or bent midpiece
with asymmetric connection to head
28. SPERM MORPHOLOGY & ITS SIGNIFICANCE
TAIL OF SPERM
• The tail piece should have a uniform caliber
along its length,
• It should be thinner than the midpiece
• Approximately 45 um long (about 10 times the
head length).
• Abnormalities are short, multiple, spiral tails
• Kinked tail or tail of irregular thickness are also
abnormal.
29. MICROSCOPIC EXAMINATION
MORPHOLOGY
OTHER CELLS WHICH MAY BE PRESENT IN
SEMEN ARE:
• IMMATURE GERM CELLS – suggest some
defect of maturation
• LEUKOCYTES – suggest some inflammatory
disease of genital tract
• AGGLUTINATION OF SPERMS – suggest some
immunological cause eg autoantibodies
30. CHEMICAL EXAMINATION & ITS
SIGNIFICANCE
• Routinely tested chemical is Fructose
• Normal seminal fructose is 150-600 mg/dl
• It is low in androgen deficiency or ejaculatory
obstruction
• This test is used for seminal stain and vaginal
aspirate in medico legal cases
31. OTHER SPECIAL TESTS
IMMUNOLOGICAL ASSAYS
• Presence of antisperm antibody binding to head or
tail antigens suggest some defect of immunity
MICROBIOLOGICAL ASSAYS
• If WBC are present in large numbers, semen should
be cultured to rule out microbial infection
SPERM FUNCTION TESTS
• These tests assess the functional aspects of the
sperm like, abilities related to transport in female
genital tract & fertilization of ovum
32. WHO 2010
Parameter Lower Reference Limit
Semen volume (ml) 1.5
Sperm concentration (106/ml) 15
Total sperm number (106/ejaculate) 39
Progressive motility (PR, %) 32
Total motility (PR +NP, %) 40
Vitality (live sperms, %) 58
Sperm morphology 40% normal forms
pH >/=7.2
Leucocyte (106/ml) <1
Fructose 1.5-6.5 mg/ml
33. REPEAT SEMEN ANALYSIS
• Should be undertaken if any abnormalities are
present
• It is best to repeat SA after a period of 10
weeks (64-70 days), as this is the time taken
for a new batch of sperm to be generated by
the testes
• There are several causes of transient defects
in semen analysis
34. TRANSIENT DEFECTS IN SA
• Incorrect semen collection technique –
spillage, dirty container, long delay in
delivering sample
• History of recent illness like flu or high fever
may depress sperm counts
• Long period of abstinence, may lead to
increased abnormal sperm morphology and
decrease motility
• Short abstinence period may cause lower
semen volume and sperm count
35. QUALITY CONTROL IN SA
• Quality Assurance Program
– Standard Operating Procedures
– Laboratory Manual
– Documentation
– Sample ID and Tracking
• External QC
– Comparison of tests with an external source
• Internal QC
– Minimized variation by training
– Purchased QC samples with known values
– Video recordings for motility
