【 摘 要 】

BackgroundPlenty of studies explored the most optimal treatment protocol for infertile women with adenomyosis in in-vitro fertilization (IVF) /intracytoplasmic sperm injection (ICSI), however, there is still no consensus on which treatment protocol is ideal for these women at present. So, we conducted this study comparing the pregnancy outcomes in infertile women with ultrasound-diagnosed adenomyosis who underwent GnRH antagonist protocol with freeze-all strategy or long-acting GnRH agonist protocol.MethodsThis was a retrospective cohort study and a propensity-score matching (PSM) analysis including 282 women diagnosed with adenomyosis undergoing their first IVF/ICSI cycle from January 2016 to July 2021 at the Assisted Reproduction Center, Northwest Women’s and Children’s Hospital, China. The patients were divided into two groups: the GnRH antagonist protocol with freeze-all strategy (n = 168) and the long-acting GnRH agonist protocol with fresh embryo transfer (n = 114) according their treatment protocols. The primary outcome was live birth rate. Cumulative live birth rate was also calculated.ResultsAfter adjusting for confounders, clinical pregnancy rate (49.40% vs 64.04%; odds ratio (OR) 1.33; 95% confidence interval (CI) 0.70 to 2.37; P = 0.358), live birth rate (36.90% vs 45.61%; OR 1.10; 95% CI 0.61 to 2.00, P = 0.753) and cumulative live birth rate (51.79% vs 64.04%; OR 1.01; 95% CI 0.49 to 1.74, P = 0.796) were not significantly different between the GnRH antagonist protocol with freeze-all strategy and long-acting GnRH agonist protocol. Similar results were conducted in PSM analysis with clinical pregnancy rate (46.48% vs 60.56%; OR 1.33; 95% CI 0.76 to 2.34; P = 0.321), live birth rate (32.39% vs 45.07%; OR 1.31; 95% CI 0.63 to 2.72, P = 0.463) and cumulative live birth rate (54.90% vs 60.60%; OR 1.01; 95% CI 0.59 to 1.74, P = 0.958).ConclusionsFor infertile women with adenomyosis, these two treatment protocols resulted in similar pregnancy outcomes. Larger, prospective studies are needed in the future.
