However, there is an increasing body of evidence suggesting that prolactin is involved in multiple physiological aspects of normal reproduction. Thus, the present paper aims to review the current literature regarding the relationship between serum prolactin level and in vitro fertilization (IVF)\/intracytoplasmic sperm injection outcome and the role of dopamine agonists treatment in IVF success. Moreover, the mechanisms by which prolactin may exert its role in fertility and infertility were summarized. Although not all studies agree, the available evidence suggests that higher prolactin levels in follicular fluid are associated with increased oocytes competence, but also with positive effects on corpus luteum formation and survival, endometrial receptivity, blastocyst implantation potential and survival of low-motile sperm. Transient hyperprolactinemia found in IVF cycles was reported in most of the studies not to be related to IVF outcome, although a few reports suggested that it may be associated with higher implantation and pregnancy rates, and better-cumulated pregnancy outcomes. Administration of dopamine agonists for hyperprolactinemia preceding IVF treatment does not seem to negatively impact the IVF results, while treatment of transient hyperprolactinemia during IVF might be beneficial in terms of fertilization rates and conception rates. Due to limited available evidence, future studies are necessary to clarify the optimal level of circulating prolactin in patients performing IVF and the role of dopamine agonist treatment.<\/jats:p>","DOI":"10.3390\/ph16010122","type":"journal-article","created":{"date-parts":[[2023,1,13]],"date-time":"2023-01-13T04:30:20Z","timestamp":1673584220000},"page":"122","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Prolactin Relationship with Fertility and In Vitro Fertilization Outcomes\u2014A Review of the Literature"],"prefix":"10.3390","volume":"16","author":[{"given":"Mirela E.","family":"Iancu","sequence":"first","affiliation":[{"name":"Endocrinology Department, ARTHOPE SRL, 077190 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alice I.","family":"Albu","sequence":"additional","affiliation":[{"name":"Endocrinology Department, Elias Emergency Hospital, 011461 Bucharest, Romania"},{"name":"Endocrinology, 2nd Clinical Department, General Medicine Faculty, \u2018Carol Davila\u2019 University of Medicine and Pharmacy, 050454 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9665-4524","authenticated-orcid":false,"given":"Drago\u0219 N.","family":"Albu","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, 2nd Clinical Department, Dentistry Faculty, \u2018Carol Davila\u2019 University of Medicine and Pharmacy, 050454 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"265","DOI":"10.1038\/nrendo.2015.36","article-title":"New insights in prolactin: Pathological implications","volume":"11","author":"Bernard","year":"2015","journal-title":"Nat.
