Frozen embryo transfer resulted in significantly higher live birth, clinical pregnancy, ongoing pregnancy, and chemical pregnancy rates compared to fresh embryo transfer in infertile women with endometriosis.

This retrospective matched cohort study compared IVF pregnancy outcomes after frozen versus fresh embryo transfer in infertile women with endometriosis treated at Shariati Hospital from 2013–2020 (105 fresh vs 92 frozen), using archive data and pregnancy outcomes obtained by phone follow-up. The groups were matched for age, BMI, primary infertility duration, base FSH level, and number of transferred embryos, and outcomes included live birth, clinical, chemical, miscarriage, and ongoing pregnancy rates. Frozen embryo transfer showed significantly higher live birth, clinical pregnancy, ongoing pregnancy, and chemical pregnancy rates than fresh transfer, while miscarriage rates did not differ significantly. The paper is a preprint and explicitly notes retrospective design limits and reliance on available records/phone follow-up. This paper is centrally about endometriosis — it evaluates how frozen versus fresh embryo transfer methods affect fertility outcomes in infertile women with endometriosis.
