What is true about lactational amenorrhea as contraception?

• A. It can temporarily suppress ovulation in exclusive breastfeeding, but it is not fully reliable; use additional contraception if needed.
• B. It completely prevents pregnancy for the entire breastfeeding period.
• C. It has no effect on fertility.
• D. It is the same as using hormonal birth control.

Answer: (A)

Lactational amenorrhea works because frequent, exclusive breastfeeding keeps prolactin high, which suppresses the hormones needed to ovulate. This can delay ovulation and reduce the chance of pregnancy in the early postpartum period, especially when breastfeeding is on demand, the baby is under six months old, and menses have not returned. But this protection isn’t guaranteed—its effectiveness depends on how strictly breastfeeding is maintained, whether other foods or liquids are given, and whether ovulation has already resumed even if menstruation hasn’t. Because of that imperfect protection, it’s advised to use another form of contraception if avoiding pregnancy is important, particularly as time passes or if breastfeeding becomes less exclusive or menses resume. So the best description is that lactational amenorrhea can temporarily suppress ovulation in exclusive breastfeeding but is not fully reliable; use additional contraception if needed.
