Abstract Background: GnRH-agonist is used to treat adenomyosis, but its efficacy in adenomyosis patients with uterine enlargement undergoing frozen embryo transfer (FET) is unclear. Methods：The retrospective cohort study comprised 112 adenomyosis patients with uterine enlargement undergoing the first FET circle. A long-term GnRH-a pretreatment was administered to 112 patients with uterine enlargement. These patients were divided into two groups according to the therapeutic effect: patients with a normal-size uterus after GnRH-a treatment (GN group) and patients with an enlarged uterus after GnRH-a treatment (GL group). Results：Not all patients can shrink their uterus to a satisfactory level. After receiving GnRH-a pretreatment, the uterus returned to normal size in 77% of patients (GN group), and 23% of patients had a persistently enlarged uterus (GL group). The pregnancy rate, clinical pregnancy rate, ongoing pregnancy rate, and live birth rate were significantly higher in the GN group than in the GL group. Controlling for the confounding factors, normal uterus size (odds ratio [OR] 4.50; P=0.03) and low body mass index (OR 3.13; P=0.03) affected the odds of achieving live birth. The cut-off value selected on the ROC curve of uterus volume after GnRH-a treatment for detecting live birth was 144.7Conclusions：GnRH-a pretreatment was associated with the regression of adenomyosis lesions and improved clinical pregnancy outcomes in the adenomyosis patients with uterine enlargement whose lesion are GnRH-a susceptible on FET cycles. However, about a quarter of patients may not be less responsive to GnRH-a and have poorer pregnancy outcomes, especially in overweight women.
