The lactational amenorrhea method (LAM) is described as what in postpartum contraception?

• A. It is highly reliable in all breastfeeding scenarios.
• B. It is limited in postpartum use.
• C. It is contraindicated in all postpartum women.
• D. It provides contraception for 12 months regardless of breastfeeding.

Answer: (B)

LAM is a temporary form of postpartum contraception that works mainly when the mother is exclusively breastfeeding and has not resumed sheddings of menses. Its protective effect hinges on prolactin levels raised by frequent, exclusive feeding, which delays ovulation. Because this relies on strict feeding patterns and time since birth, its effectiveness is limited to the early postpartum period—about the first six months—and only if breastfeeding remains exclusive. If the baby starts solid foods, receives formula, feeding becomes less frequent, or menses return, LAM no longer provides reliable contraception. It is not intended to cover a full year or under all breastfeeding circumstances, and other methods should be used once any of these conditions aren’t met.
