WHO guidelines contraindicate combined hormonal contraceptives postpartum in breastfeeding patients between 6\u2009weeks and 6\u2009months after delivery (Medical Eligibility Criteria category 3). On the contrary, the Faculty of Sexual and Reproductive Healthcare and the Centers for Disease Control and Prevention guidelines do not contraindicate their use in women who breastfeed from 6\u2009weeks to 6\u2009months postpartum. New combined hormonal contraceptives with natural estrogens have never been studied in this setting. Guidelines agree on the prescription of the progestin\u2010only pill postpartum in non\u2010breastfeeding women (category 1). Differences are found in women who breastfeed. In non\u2010breastfeeding women, an implant is considered safe (category 1) by all guidelines, without any distinction in time. Regarding postpartum breastfeeding women, the guidelines for implants give quite different indications but are still permissive. Intrauterine devices are viable options for postpartum contraception but guidelines give different indications about the timing of insertion. Postplacental intrauterine device placement can reduce the subsequent unintended pregnancy rate, particularly in settings at greatest risk of not having recommended postpartum controls. However, it has yet to be understood whether this approach can really have an advantage in high\u2010income countries. Postpartum contraception is not a \u2018matter of guidelines\u2019: it is the best customization for each woman, as early as possible but at the ideal timing.<\/jats:p>","DOI":"10.1002\/ijgo.14928","type":"journal-article","created":{"date-parts":[[2023,6,19]],"date-time":"2023-06-19T11:00:27Z","timestamp":1687172427000},"page":"56-65","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Postpartum contraception: A matter of guidelines"],"prefix":"10.1002","volume":"164","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3567-3278","authenticated-orcid":false,"given":"Giovanni","family":"Grandi","sequence":"first","affiliation":[{"name":"Department of Medical and Surgical Sciences for Mother, Child and Adult, University of Modena and Reggio Emilia Azienda Ospedaliero Universitaria Policlinico  Modena Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria C.","family":"Del\u00a0Savio","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences for Mother, Child and Adult, University of Modena and Reggio Emilia Azienda Ospedaliero Universitaria Policlinico  Modena Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alice","family":"Tassi","sequence":"additional","affiliation":[{"name":"Clinic of Obstetrics and Gynecology DAME, University Hospital of Udine  Udine Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabio","family":"Facchinetti","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences for Mother, Child and Adult, University of Modena and Reggio Emilia Azienda Ospedaliero Universitaria Policlinico  Modena Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,6,19]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/ppe.12503"},{"key":"e_1_2_12_3_1","unstructured":"Report of a WHO technical consultation on birth spacing: Geneva Switzerland 13\u201315 June 2005.
