Interception. III: Postcoital luteal contragestion by an antiprogestin (mifepristone, RU 486) in 62 women.
The new antiprogestin mifepristone (RU 486) was studied as an emergency postcoital contragestive. An actual pregnancy rate of 1.6% was observed and was related to the actual conception rate. The follow-up rate was 100%. The patterns of onset and duration of the induced menstruation after mifepristone treatment are described. This method provides a good new interceptive technique when the time for use of postcoital steroids or for a postcoital IUD insertion has lapsed.
