Document Summary
Gnrh signals anterior pituitary to release fsh and lh. Hypothalamus releases gnrh anterior pituitary release of fsh/lh trigger gonads to release sex hormones (ovaries = estrogen, progesterone; testes = androgens = testosterone) Primary sex organs are the gonads, produce gametes. One oocyte produced/matures monthly from 400,000 primordial follicles (limiting factors) Fertilization occurs when male and female gametes meet zygote (diploid) Ovary = testis = produce gametes and sex hormoes. Clitoris = glans of penis = ans axons, sexual climax feelings. Labia majora (protects round ligament) = scrotum (houses testis) = protect and cover some reproductive structures. Vestibular glands = bulbourethal glands = secrete mucus for lubrication. Accessory = uterine tube, vagina, external genatalia, etc. Oocyte released by ovulation into serous fluid in peritoneal cavity. Fimbriae = create current to pull oocyte into uterine tube into infundibulum. Oocyte can be fertilized in ampulla will implant in endometrium for nutrition.
