Maximum activity was localized in normal pregnancies rose from 13.58 ng\/ml in the 6th week to 52.46 ng\/ml in the 15th week of gestation with marked individual variability. In tubal pregnancies, serum hPRL was low and did not increase over a period of 3\u20136 weeks. In women with spontaneous abortion, hPRL levels often were in the normal range with a drop only immediately prior to expulsion of the fetus. In patients with missed abortion the drop in serum prolactin levels seemed to coincide with the death of the conceptus.<\/jats:p>","DOI":"10.1159\/000299829","type":"journal-article","created":{"date-parts":[[2010,3,17]],"date-time":"2010-03-17T05:58:36Z","timestamp":1268805516000},"page":"113-118","source":"Crossref","is-referenced-by-count":2,"title":["First-Trimester Serum Prolactin Levels in Normal and Complicated Pregnancies"],"prefix":"10.1159","author":[{"given":"P.","family":"Riss","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Mick","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Spona","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,16]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000299829","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:41:40Z","timestamp":1777617700000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000299829"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000299829","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,16]]}}}
