Lactational Amenorrhea Method Lactational Amenorrhea Method

The lactational amenorrhea method (LAM) is a modern contraceptive method based on the natural infertility resulting from full or nearly full breastfeeding in the absence of menses in the first six months postpartum. LAM - more than 98 percent effective when typically used - contributes to the first six months of the birth spacing interval. Women who become pregnant less than six months after their last delivery are at 2.5 times greater risk of pregnancy and childbirth related deaths. Operations research has demonstrated that promotion of LAM attracts first time family planning users. Promotion of LAM within family planning programs also increases optimal breastfeeding.

LINKAGES worked through ongoing family planning and maternal child health programs to promote LAM and the timely use of all family planning methods appropriate for breastfeeding mothers, as well as to improve referral for family planning and nutrition services. LINKAGES conducted applied research in Jordan to evaluate LAM's impact as a "bridging" method to other modern contraceptives after six months postpartum.
