Abstract

Objective: To determine if uterine adenomyosis is associated with worse perinatal outcomes in ovum donation assisted reproductive treatment cycles. Materials & Methods: A multicenter and retrospective cohort in which a total of 3307 patients undergoing an ovum donation cycle in 2018–2019 were included and divided into two groups: adenomyosis (n = 179) and controls (n = 3128). Clinical, obstetric, and perinatal outcomes were analyzed. Result(s): A lower live birth rate per embryo transfer was observed in women diagnosed with adenomyosis versus the controls: 67/179 (37%) versus 1560/3128 (49.9%), respectively (OR = 0.6 95% CI 0.43–0.83, P = 0.002). There was no statistically significant difference in childbirth delivery method (vaginal versus cesarean section) between the adenomyosis and control groups. Mean gestational age at the time of delivery, newborn length and weight, and incidences of low birth weight, preterm birth, and admission to the neonatal intensive care unit did not differ between the two groups. In addition, IVF and perinatal outcomes were similar in patients with diffuse compared with focal adenomyosis. Conclusion(s): Adenomyosis affects clinical but may not affect perinatal outcomes in ovum donation cycles.
