Cumulative pregnancy rate via multiple fresh or frozen embryo transfers in women with current, resected, or recurred endometrioma

Objective: This study aimed to retrospectively analyze the cumulative pregnancy rate (PR) via multiple fresh or frozen embryo transfers (ET) in women with current, resected, or recurred endometrioma. Materials and methods: The IVF data including oocyte pick-up (OPU) and fresh or frozen ET in women with current (37 women; 56 OPU, 18 fresh and 14 frozen ET), resected (24 women; 50 OPU, 17 fresh and 42 frozen ET), or recurred endometrioma (28 women; 49 OPU, 22 fresh and 24 frozen ET) were obtained. All cycles were performed from 2015 to 2022 in a single university hospital. Results: The median serum AMH level (ng/mL) was 1.44, 1.47, and 0.98, respectively. The number of total or mature oocytes, fertilized oocytes, cleavage embryos at day-3, and top-quality embryos at day-3 were all similar in the three groups. Cycles with no oocyte occurred in 2 (3.6%), 1 (2%), and 3 cycles (6.1%), respectively. Freeze-all was performed in 46.3%, 59.2%, and 47.8% of the cycles, respectively (p > 0.05). The cumulative clinical PR per total ET (43.8%, 25.4%, and 21.7%), per OPU (25%, 30%, and 20.4%), and per woman (37.8%, 62.5%, and 35.7%) were all similar in the three groups. The cumulative ongoing pregnancy and live birth rate per total ET, per OPU, and per woman were also similar in the three groups. Conclusion: Similarity in ovarian reserve, number of oocytes, number of embryos, cumulative clinical PR, and live birth in the three endometriosis groups indicates that the IVF outcomes in the ‘recurrent endometrioma’ group are not inferior to ‘current’ or ‘resected’ group
