title: Contraception in lactating women.
abstract: Lactating women need contraception after first menses, supplementation or 6 months postpartum, or before, according to personal or programmatic reasons. Non-hormonal methods have no influence on lactation and are the first choice. Intrauterine devices (IUDs) inserted during amenorrhea are safe and show good continuation rates. Progestin-only methods do not affect breast-feeding and should be used after 6 weeks to prevent transference of orally active steroids to the newborn. Progesterone rings and Nestorone implants are effective new methods, that use orally inactive steroids.
