What is the lactational amenorrhea method (LAM) of family planning?
LAM is a contraceptive method that is based on the natural postpartum infertility that occurs when a woman is amenorrheic and fully breastfeeding. How does LAM work? (mechanism of action)
The infant's suckling suppresses the production of the hormones that are necessary for ovulation. Without ovulation, pregnancy cannot take place. Who can use LAM?
Women who have all three of the following criteria present:
Exclusively or almost exclusively breastfeeding
Have not had menses since giving birth
Are less than six months postpartum To use LAM, a woman should breastfeed:
Soon after delivery
Frequently, upon request, not on schedule
Without bottles or pacifiers
Without long intervals between feeds, both day and night
Without supplementation
Even when mother and/or baby are ill Advantages
Highly effective (at least 98%)
