Corpus luteum creates progesterone. Progesterone is the main hormone which builds up endometrial lining. Cycle ends with deterioration of egg and corpus luteum if not implanted, stops production of progesterone & the LH/FSH from pituitary gland, lining begins to fall off, starts menstrual cycle. Eventually the hypothalamus reading low estrogen/progesterone levels tells the pituitary gland to release FSH (Follicle Stimulating Hormone) to develop follicles. 4­5 days later, the LH takes over and matures it and it ruptures within 24 hours. START CYCLE OVER AGAIN Cycle continues until menopause or pregnancy or sudden loss in weight. During pregnancy, the placenta releases HCG (pregnancy hormone). HCG produced in these amounts only during pregnancy. After 2 weeks of this production there is enough of it to register on a pregnancy urine test. HCG keeps corpus luteum alive which keeps up production of progesterone. Progesterone production during pregnancy ensures that the endometrial lining does not fall off. Breasts: Men have the same parts in their breasts, just some pieces aren’t as fully developed (mammary glands). Estrogen develops mammary glands. Prolactin: causes milk production in mammary glands. Only present after delivery, it continues as long as breast are suckled after pregnancy. ­­> wet nurses. The sucking is what causes the pituitary gland to produce prolactin. Colostrum: Released from nipple. pre­milk. Often babies will get this during their first feeding. Oxytocin: Causes contractions in female menstrual cycle. Also can be released by sexual arousal or nipple suckling. Causes ejection of milk by small contractions in breasts. This will be produced for as long as nipples are being stimulated after a pregnancy, meaning milk will be produced as long as desired until child is no longer being breastfed. Oxytocin causes you to have positive feelings to those around you. Bonds you to sexual partner during intercourse or 6 your baby during breast feeding. Random notes: Zona Pellucida: Gives protection from bacteria for the egg, allows sperm to pass through *Only one sperm passes through the egg membrane, which changes the polarity of it and prevents other sperm from getting to the egg. Acrosome: Equivalent of zona pellucida for sperm, protects it as it travels to the egg Dates to Remember: 313 Constantine Converted to Christianity: Before 313, Romans believed in Zeus and Gods, and Christians were punished. After 313, Christianity became the religion and non­christians were punished. 353­430 Augustine:settled the question between Jesus’ birth! Whether it was derived from sex or not. And the conclusion, was since Jesus was perfect, then he was of virgin birth. Since then, sin has been passed down from generation to generation, because of lust. We are “born in a state of sin.”...
