Lactational Amenorrhea Method (LAM)

What is this intervention? 

  • LAM is a temporary contraceptive method that uses a pattern of breastfeeding to effectively suppress ovulation and prevent pregnancy. When used correctly, LAM is greater than 98% effective.3 
  • To use LAM, women and providers follow three simple criteria:
    • Exclusive breastfeeding
    • Amenorrhea (no vaginal bleeding > 2 months postpartum)
    • Infant < 6 months

Why is this intervention needed?

  • Supports mothers to exclusively breastfeed their infants for the first six months, which increases the likelihood of infant survival.
  • Is culturally acceptable and provides an opportunity for fathers and mothers to discuss FP in traditional cultures in the context of healthy spacing for the well being of their infant.
  • Clarifies the difference between breastfeeding and LAM for both providers and mothers, including how long it is effective as an FP method.
  • Serves as a gateway to other modern methods: multinational research shows that 70 % of women who accept LAM are using a modern method of contraception at 12 months postpartum.4
