The contraceptive effect of lactation has been recognised for a long time, but detailed knowledge concerning the size and duration of this effect, and necessary preconditions has been lacking. Research on the lactational amenorrhoea method has given new insight into these matters. A consensus statement from 1988 concluded that women are protected against a new pregnancy during the first six months post-partum, provided they practise exclusive breast-feeding and remain amenorrhoeic. Recent research indicates that supplementary feeding does not disrupt this protection, which may last even beyond six months. Breast-feeding has a contraceptive effect also after resumption of menses, but this is too uncertain to be used in systematic family planning. The lactational amenorrhoea method should become an integrated element of family planning programmes.
哺乳期的避孕作用早已得到认可，但关于这种作用的程度、持续时间以及必要前提条件的详细知识一直欠缺。对哺乳期闭经避孕法的研究为这些问题提供了新的见解。1988年的一份共识声明指出，产后头六个月内，如果妇女坚持纯母乳喂养且仍处于闭经状态，她们就能避免再次怀孕。近期研究表明，添加辅食并不会破坏这种避孕效果，这种效果甚至可能持续超过六个月。月经恢复后，母乳喂养也有避孕作用，但这种作用不太确定，因此不能用于系统的计划生育。哺乳期闭经避孕法应成为计划生育项目的一个组成部分。
