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.
哺乳期妇女在首次月经后、产后补充期或产后6个月后，或根据个人或计划原因在之前就需要避孕。非激素方法对哺乳无影响，是首选。闭经期间插入的宫内节育器（IUD）是安全的，且续用率良好。仅含孕激素的方法不影响母乳喂养，应在产后6周后使用，以防止口服活性类固醇转移给新生儿。孕激素环和内美通植入剂是有效的新方法，它们使用的是口服无活性的类固醇。
