The downregulation of gonadotropin releasing hormone agonists (GnRH-a) is regarded as an effective approach to reducing the size of intramural fibroids and enhancing endometrial receptivity. Consequently, we conducted this study to assess whether the GnRH-a combined with hormone replacement therapy (GnRH-a-HRT) can improve reproductive outcomes in frozen embryo transfer cycles for patients with a thin endometrium (≤ 7 mm) and intramural fibroids.Methods: This retrospective cohort study encompassed 360 patients who underwent frozen embryo transfer following in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Patients were stratified into three groups based on the endometrial preparation protocol: the natural cycle (NC) group (n=96), the hormone replacement therapy (HRT) group (n=180), and the GnRH-a-HRT group (n=84). The live birth rate (LBR) was designated as the primary outcome, while clinical pregnancy rate (CPR), miscarriage rate, and ectopic pregnancy rate were classified as secondary outcomes.Results: The LBR and CPR in the GnRH-a-HRT group were significantly higher than those in both the HRT group and the NC group (both P < 0.0001). A logistic regression model indicated that the LBR was significantly higher in the GnRH-a-HRT group compared to both the HRT group (odds ratio, 0.269; 95% confidence interval, 0.114– 0.637; P = 0.003) and the NC group (odds ratio, 0.524; 95% confidence interval, 0.457– 0.956; P = 0.023). Subgroup analyses based on the number and dimension of fibroids demonstrate the positive efficacy of the GnRH-a–HRT regimen.Conclusion: Compared to NC and HRT protocol, improved reproductive outcomes were observed in the GnRH-a–HRT group. These findings provide valuable insights for exploration of the underlying mechanisms by which the GnRH-a-HRT protocol enhances reproductive outcomes in patients of thin endometrium with intramural fibroids.Keywords: frozen embryo transfer, live birth rate, clinical pregnancy rate, thin endometrium, intramural fibroid |
