The study included a total of 9351 women who had undergone therapy at our single tertiary hospital from January 2015 to July 2020. The women were divided into three groups depending on their endometrial regimens: natural cycle, stimulation cycle, hormone replacement therapy cycle. The data were analyzed after propensity score matching, then we used multiple linear regression to study the relationship between ischemic placental disease and endometrial regimens, adjusted by confounding factors including age, body mass index, and score of propensity score matching. We performed univariate logistic regression, as well as multivariate logistic regression for ischemic placental disease, small for gestational age infant, placental abruption. and pre-eclampsia, respectively, listing the odds ratio and p-values in the table. As a result, risk of ischemic placental disease and small for gestational age infant were detected as higher in stimulation cycles compared to natural cycles before or after adjustment. Hormone replacement therapy cycles conferred a higher risk of pre-eclampsia and preterm delivery compared to natural cycles. No difference was found between stimulation cycles and hormone replacement therapy cycles, regardless of whether they are adjusted or not. In summary, more pharmacological intervention in endometrial preparation was associated with a higher risk of ischemic placental disease related symptoms than natural cycles for endometrial preparation in women undergoing frozen embryo transfer. Our findings supported that minimizing pharmacological interventions during endometrial preparation when conditions permit has positive implications for improving pregnancy outcomes.<\/jats:p>","DOI":"10.3390\/jcm11216506","type":"journal-article","created":{"date-parts":[[2022,11,3]],"date-time":"2022-11-03T03:53:07Z","timestamp":1667447587000},"page":"6506","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Effects of Different Endometrial Preparation Regimens during IVF on Incidence of Ischemic Placental Disease for FET Cycles"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8754-6644","authenticated-orcid":false,"given":"Yingjie","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Assisted Reproduction, Shanghai Ninth People\u2019s Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiuju","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Assisted Reproduction, Shanghai Ninth People\u2019s Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Assisted Reproduction, Shanghai Ninth People\u2019s Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/j.ejogrb.2011.07.025","article-title":"Ischemic placental disease: Epidemiology and risk factors","volume":"159","author":"Ananth","year":"2011","journal-title":"Eur.
