complete human reproduction
At copulation, or sexual intercourse, the erect penis is inserted into the vagina, and spermatozoa contained in the seminal fluid (semen) are ejaculated into the female genital tract. Spermatozoa then pass from the vagina through the uterus to the fallopian tube to fertilize the ovum in the outer part of the tube.
The reproductive events in humans include formation of gametes (gametogenesis), i.e., sperms in males and ovum in females, transfer of sperms into the female.
Human reproduction is any form of sexual reproduction resulting in human fertilization. It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
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.

3. Reproductive Anatomy of the Human
Male.
External:
- penis
- scrotum
Internal:
- gonads
- accessory sex glands and ducts.
Human reproduction involves intricate
anatomy and complex behavior
8. Testis are the male gonads.
seminiferous tubules- form sperm
Leydig cells (interstitial cells)- produce
androgens (ex. Testosterone, ABP).
9. Testes are located in the scrotum,
outside the body cavity.
This keeps testicular temperature cooler
than the body cavity.
The testes develop in the body cavity and
descend into the scrotum just before birth.
11. Semen
Seminal fluid is thick, yellowish, and
alkaline.
It contains mucus, fructose, a coagulating
enzyme, ascorbic acid, and
prostaglandins.
Accessory glands:
1.seminal vesicle
2.prostate gland
3.bulbourethral gland
12. Seminal Vesicle
Seminal vesicle:
• A pair of glands that secrete a liquid
component of semen into the vas deferens.
• Secretion is alkaline
• Contains fructose, asorbic acid, coagulating
enzyme, prostaglandin
13. Prostate gland:
• Location- surrounds and opens into the urethra where it
leaves the bladder.
• Secretion- slightly alkaline fluid that activates the sperm
and prevents them from sticking together
Prostate problems are common in males over 40.
Prostate cancer is one of the most common cancers
in men.
Prostate
14. Bulbourethral gland (Cowper’s gland):
• Location- paired glands that lie beneath the prostate
• Secretion- a thick, clear alkaline mucous that drains into
the membranous urethra.
• Function- It acts to wash residual urine out of the urethra
when ejaculating semen-- raises pH; neutralizes acidity of
urine.
Bulbourethral
gland
21. Feedback Inhibition
Inhibin
Acts on anterior pituitary
Inhibits FSH production
Testosterone
Acts on hypothalamus
Inhibits GnRH production
Hormonal Control of
Spermatogenesis
22. Some Other Effects of
Testosterone
muscle and bone growth
facial and pubic hair growth
thickening of vocal cords
growth of pharyngeal cartilage
hair follicle effects
stimulates sebaceous glands
Increased BMR
29. Oogenesis
Ovary- contains 400,000 oocytes; release
about 500 in a lifetime
• Ovary- under influence of FSH. The
follicles mature every 28 days
• Primary follicle produces estrogens
• And primary oocyte completes its 1st
division produces 2ndary oocyte and
polar body
30. Oogenesis
• Aprox 1/2 way through the 28 day cycle the
follicle reaches the mature Vesticular or
Graffian follicle stage.
41. Some Other Effects of
Estrogen
• breast development
• external genitalia growth
• bone growth
• fat deposition
• Increase protein anabolism
• Decrease blood cholesterol
• Facilitate calcium uptake
• Promotes hydration of skin
• Feminizes brain
42. Menopause: cessation of ovarian and
menstrual cycles.
Usually occurs between ages 46 and 54.
Due to ovaries decreased responsiveness
to gonadotropins.
Menopause affects:
changes in sexual desire
triggers mood swings
causes debilitating hot flashes
may lead to bone and heart problems
short-term memory loss
insomnia
