Abstract

Research question: What is the population undergoing the ROPA (Reception of Oocytes from Partner) method and what are the outcomes of the technique?Design: Case series of all ROPA treatments carried out between 2011 and 2020 in 18 fertility clinics in Spain. Demographic characteristics, cycle features, laboratory and clinical outcomes, and the intentions regarding the disposition of surplus embryosResults: Donor patients were on average 3.5 years younger than recipients (P = 0.001). No significant differences were found in body mass index or anti-Mueurollerian hormone. In 13% of cases, fertility issues were found: poor ovarian reserve (6.8%); endometriosis (2.9%); and polycystic ovary syndrome (2.2%). Including cases of advanced age (38 years old or older), more than one-half of couples (53.6%) had some condition that could affect fertility. Mean number of mature oocytes per cycle was 10 (+/- 5.7), and fertilization rate was 74.5% (+/-18.8). Mean number of viable embryos was 3.2 (+/- 1.5). Surplus embryos were cryopreserved in 50.4% of cycles. Outcomes after embryo transfers from ROPA, and subsequent frozen cycles were as follows: positive pregnancy test (61.0%), clinical pregnancy (54.1%) and miscarriage rate (16.1%). Other outcomes were live birth rate per embryo transfer (44.7%); multiple pregnancy rate (5.4%); per cumulative ROPA cycle (48.6%); and per couple (61.6%).Conclusion: The outcomes of the ROPA method are reassuring. About one-half of the ROPA cycles resulted in a live birth and one-quarter of the cycles had surplus embryos after achieving a live birth. Main neonatal outcomes were also reassuring.
