BACKGROUND: The relationship between endometrial thickness and adverse pregnancy outcomes has garnered significant attention from researchers. The aim of this study was to investigates whether endometrial thickness (EMT) is a risk factor for hypertensive disorders of pregnancy (HDP) in women undergoing in vitro fertilization (IVF) due to male-factor infertility.
METHODS: This single center retrospective cohort study included 2,536 women aged 20-40 years with male-factor infertility who underwent their first frozen-thawed embryo transfer (FET) and had a singleton live birth. Endometrial thickness was measured via transvaginal ultrasound on the day of embryo transfer, and patients were divided into three groups: ≤8 mm, 8-14 mm, and ≥14 mm. The primary outcome was the incidence of HDP.
RESULTS: The overall HDP rate was 3.67%, with no significant difference across EMT groups: 3.97% in the ≤ 8 mm group, 3.74% in the 8-14 mm group, and 3.03% in the ≥ 14 mm group (p=0.760). Older maternal age and higher BMI were significant risk factors for HDP [maternal age (OR 1.10, 95% CI 1.05-1.16, p=0.000) and BMI ≥ 24.0 Kg/m² (OR 2.40, 95% CI 1.10-5.25, p=0.028)], while EMT was not associated with HDP risk.
CONCLUSION: Endometrial thickness was not a significant risk factor for HDP in women with male-factor infertility undergoing their first FET.
