Treatment outcomes of infertile women with endometrial hyperplasia undergoing their first IVF/ICSI cycle: A matched-pair study.

OBJECTIVE

The aim was to analyze the clinical characteristics, controlled ovarian stimulation status, pregnancy outcomes, and major factors influencing live births in patients with endometrial hyperplasia (EH) undergoing IVF/ICSI for assisted reproduction, so as to identify potential intervention measures.

STUDY DESIGN

Patients with EH who achieved complete remission (CR) after conservative treatment and who were undergoing their first IVF/ICSI cycle were included in this matched-pair study. Patients with normal endometriums were matched at a 1:2 ratio with the control group for the first cycle of controlled ovarian stimulation. Matching was based on age, and reproductive outcomes were analyzed.

RESULTS

Among the 263 patients (including 51 cases with atypical endometrial hyperplasia) in the study group, the pregnancy rate after the first controlled ovarian stimulation cycle was 48.67 % (128/263), and the live birth rate was 34.98 % (92/263). Multiple logistic regression analysis revealed that maternal age, body mass index (BMI), and endometrial thickness were significantly associated with live births (P<0.001). Specifically, being aged ≥ 35 years (OR 0.450, 95 % CI 0.223-0.907) and having a BMI≥28 kg/m (OR 0.358, 95 % CI 0.161-0.798) were identified as unfavorable factors for a clinical live birth, while an endometrial thickness ≥ 10 mm was found to be a favorable factor.

CONCLUSION(S): ART is effective in patients with EH who have achieved CR after conservative treatment. Avoiding unnecessary intrauterine procedures, controlling body weight appropriately, and choosing suitable ART methods as soon as possible may be beneficial for clinical outcomes.
