【摘要】 观察排卵期服用300mg米非司酮进行房事后避孕的效果和对月经的影响,在对照周期、用药周期和恢复周期,血浆雌二醇(E2)、孕酮(P)和黄体生成素(LH)浓度的变化,以及米非司酮对分泌期子宫内膜的影响。接受85名育龄妇女为受试者。60例主要观察避孕效果和月经恢复情况,另25例在三个不同周期中,定期取静脉血测三种激素水平,并在服米非司酮后第4~5天,取子宫内膜进行形态学检查。共观察129个服药周期,妊娠率为0.78%。其中18个周期出现服米非司酮后阴道少量出血,但未干扰正常月经规律,无明显副反应发生。在用药周期和恢复周期中,血浆E2、P和LH的水平未受影响。形态学检查显示子宫内膜发育延迟。本研究联合使用几种监测排卵方法,提示在排卵后72小时内服300mg米非司酮安全、有效,在分泌早期服用米非司酮可以考虑作为一月一次的避孕方法。
