Exogenous luteal phase support is given to overcome these issues. The suitability of a pragmatic approach to luteal phase support is not known due to a lack of data on early phase luteal hormone levels and their association with fertility outcomes during IVF with fresh embryo transfer. This study determined early luteal phase profiles of serum progesterone, 17-hydroxyprogesterone and hCG, and associations between hormone levels\/hormone level profile after hCG trigger and the live birth rate in women undergoing IVF with fresh embryo transfer.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This prospective single center, cohort study was conducted in Vietnam from January 2021 to December 2022. Women aged 18\u201338 years with normal ovarian reserve and undergoing controlled ovarian stimulation using a gonadotropin-releasing hormone antagonist protocol were included. Serum hormone levels were determined before trigger, at 12, 24 and 36\u00a0h after hCG, and daily from 1 to 6 days after oocyte pick-up. Serum hormone level profiles were classified as lower or upper. The primary outcome was live birth rate based on early luteal phase hormone level profile.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Ninety-five women were enrolled. Live birth occurred in 19\/69 women (27.5%) with a lower progesterone profile and 13\/22 (59.1%) with an upper progesterone profile (risk ratio [RR] 2.15; 95% confidence interval [CI] 1.28\u20133.60), and in 6\/31 (19.4%) versus 26\/60 (43.3%) with a lower versus upper serum 17-hydroxyprogesterone profile (RR 2.24; 95% CI 1.03\u20134.86). Nearly 20% of women had peak progesterone concentration on or before day 3 after oocyte pick-up, and this was associated with significantly lower chances of having a life birth.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>These data show the importance of proper corpus luteum function with sufficient progesterone\/17-hydroxyprogesterone production for achievement of pregnancy and to maximize the chance of live birth during IVF.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Trial Registration<\/jats:title>\n                <jats:p>NCT04693624 (<jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"http:\/\/www.clinicaltrials.gov\">www.clinicaltrials.gov<\/jats:ext-link>).<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12958-024-01229-3","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T05:01:48Z","timestamp":1716181308000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["In vitro fertilization outcome based on the detailed early luteal phase trajectory of hormones: a prospective cohort study"],"prefix":"10.1186","volume":"22","author":[{"given":"Lan","family":"N Vuong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toan","family":"D Pham","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vu","family":"N A Ho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anh","family":"T L Vu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tuong","family":"M Ho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claus","family":"Yding Andersen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"key":"1229_CR1","doi-asserted-by":"publisher","first-page":"709","DOI":"10.1210\/jcem.87.2.8197","volume":"87","author":"BC Fauser","year":"2002","unstructured":"Fauser BC, de Jong D, Olivennes F, Wramsby H, Tay C, Itskovitz-Eldor J, van Hooren HG.
