What is the best time after childbirth to accept contraception? The problem is to reduce overlap with postpartum anovulation, during which contraception is redundant, but simultaneously to reduce the proportion of women conceiving before contraception is inaugurated. Efficiencies of three classes of acceptance strategies at resolving this dilemma are investigated. Particular attention is paid to the postpartum acceptance rule because of its special administrative advantages. Its efficiency relative to those of other rules is found to be enhanced by conditions of short postpartum anovulation, a high proportion of ovulatory rather than anovulatory first menstrual cycles, a high level of natural fecundability, and, especially, a high level of contraceptive continuation.
产后接受避孕的最佳时间是什么时候？问题在于减少与产后无排卵期的重叠，在此期间避孕是多余的，但同时要减少在开始避孕之前怀孕的女性比例。研究了三类接受策略在解决这一困境方面的效率。由于其特殊的管理优势，特别关注产后接受规则。发现相对于其他规则，在产后无排卵期短、排卵而非无排卵的首次月经周期比例高、自然受孕能力高，尤其是避孕持续率高的情况下，产后接受规则的效率会提高。
