Postcoital Fertility Control

Medical Condition:
Postcoital Fertility Control

Contraceptive substances to be used after coitus. Usually high doses of estrogen are administered within 24-36 hours after coitus as an emergency measure, not as a replacement for the usual methods of contraception because of the side effects of high concentration of estrogen. (From Dictionary of Obstetrics and Gynecology, 1988, p55)
