The contraceptive effects of breast-feeding still play an important role in child spacing in developing countries; however, its use as a method of family planning was untested until 1988, when an international group of researchers met in Bellagio and reached a consensus statement that reads "The maximum birth spacing effect of breast-feeding is achieved when mothers fully or nearly fully breast-feed and remain amenorrheic (and no menstrual bleeding has occurred before the 56th postpartum day). When these two conditions are present, breast-feeding provides more than 98% of protection in the first six months. That became the basis for a method of family planning called the lactational amenorrhea method (LAM). Which is a new introductory family planning method that simultaneously promotes child spacing and breast-feeding, with its optimal nutrition and disease preventive benefits for the infant. This method is based on the natural infertility caused by the hormonal suppression of ovulation.
母乳喂养的避孕效果在发展中国家的生育间隔中仍发挥着重要作用；然而，直到1988年，它作为一种计划生育方法才得到验证。当时，一个国际研究小组在贝拉吉奥会面，并达成了一份共识声明，内容如下：“当母亲完全或几乎完全母乳喂养且仍处于闭经状态（产后第56天之前未出现月经出血）时，母乳喂养的生育间隔效果最佳。当这两个条件同时满足时，母乳喂养在前六个月提供超过98%的避孕保护。”这成为了一种名为哺乳期闭经法（LAM）的计划生育方法的基础。这是一种新的计划生育方法，它同时促进生育间隔和母乳喂养，对婴儿具有最佳的营养和疾病预防益处。该方法基于排卵受激素抑制导致的自然不孕。
