Abstract
PIP:
The current status of and prospects for contraceptive methods is reviewed. Regulations governing the development, safety, and effectiveness of contraceptive methods are discussed, as well as the nature of the female and male reproductive system. Methods reviewed include coitus interruptus, the condom, spermicidal contraceptive agents, postcoital douching, the vaginal diaphragm, male and female sterilization, the rhythm method, oral contraceptives, IUDs, induced abortion, progesterone-releasing IUDs, postcoital estrogens, abortifacient agents (prostaglandins), immunization against human chorionic gonadotropin (HCG), pharmacologic suppression of the corpus luteum, long-acting injections of Depo-Provera, implantation of capsules containing norgestrel, the intravaginal ring, intracervical devices, release of contraceptive steroids through an arm bracelet, and male contraceptive agents. New areas of contraceptive research include influencing the release of luteininzing hormone-releasing hormone, ''turning-off'' corpus luteum function in early pregnancy by competitors for HCG, affecting sperm or ovarian membranes to prevent fertilization, and interferring with sperm and egg development.
