These conclusions, however, are based on incomplete safety assessments and potentially misleading pharmacokinetic assumptions. This critical appraisal highlights several concerns: (1) discrepancies between published and regulatory data on bleeding/spotting rates compared to established EE/DRSP combinations; (2) inappropriate reliance on clotting-time-based activated protein C resistance (APCr) assays that fail to detect contraceptive-induced hypercoagulability; and (3) a strikingly high incidence of venous thromboembolism (VTE) reported in clinical trials of prolonged-release EE/DNG, significantly exceeding rates associated with both traditional EE-based and newer body-identical estrogen-containing contraceptives. Furthermore, these VTE cases are not transparently discussed in the peer-reviewed literature, raising ethical concerns about selective reporting. The pharmacokinetic profile of this formulation does not appear to mitigate estrogenic hepatic effects in a clinically meaningful way. Robust evaluation using validated thrombin generation assays such as the endogenous thrombin potential (ETP)-based APCr test, alongside independent post-marketing studies, is essential before asserting a neutral or favorable safety profile.

Consistent with these findings, GIP treatment decreased testosterone release and downregulated the expression of GIP receptor (GIPR), steroidogenic acute regulatory protein (STAR), cytochrome P450 family 11 subfamily A member 1 (CYP11A1), and cytochrome P450 family 17 subfamily A member 1 (CYP17A1) in NCI-H295R cells. Notably, RNA-seq revealed that <i>PSENEN</i> was the most significantly downregulated gene upon GIP stimulation. Knockdown of <i>PSENEN</i> in NCI-H295R cells further decreased testosterone levels in the culture medium, confirming the inhibitory effect of GIP on androgen synthesis.</p><p><strong>Conclusions: </strong>Our study demonstrated that the administration of GIP reduces androgen synthesis in PCOS mouse models and at the cellular level, suggesting its potential as a novel therapeutic target for managing PCOS.</p>","PeriodicalId":12865,"journal":{"name":"Gynecological Endocrinology","volume":"41 1","pages":"2582506"},"PeriodicalIF":1.7,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145540017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
