Document Summary
Cause low level of inflammation in endometrium so fertilized egg cant settle down anywhere. e. g. , morning after pills and intrauterine devices (iuds) these keep eggs from being fertilized from implanting into endometrium: abortifacients. They cause the termination of an established pregnancy. Egg is invaded into endometrium and you need to kill it through mifepristone: anti-progesterone, blocks progesterone receptors and uterus doesn"t stay quiet, it contracts easy. e. g. , mifepristone (ru 486) Male side: production of viable sperm: no birth control or anything to prevent men from producing sperm. If you turn off sperm production you turn off sex drive. You can stop transport of viable sperm through a vasectomy: take vas eferons and cut them and burn both sides. Deposit of sperm in vagina: through condom or coitus interruptus (cid:0) when you ejaculate you don"t ejaculate near the vagina. Survival of sperm in vagina: there are spermicides (cid:0) acidic that kills sperm. Movement of sperm to uterine tubes: cervical cap, diaphragm.
