[Becoming requesting couples after their registration in oocyte donation].

Objectives: Many studies have investigated the causes of discontinuation during intraconjugal medically assisted procreation. However, there are currently very few data justifying the causes of discontinuation during the oocyte donation program. The main objective of this study is to determine the causes of discontinuation in oocyte donation and their respective frequency, excluding live births by oocyte donation in our center.

Methods: This is an observational, retrospective, single-center study focused on receiving or requesting couples who stopped their oocyte donation program between January 1, 2005 and April 29, 2021. A total of 390 couples were included in the study.

Results: Of the 390 couples included, 306 couples or nearly 80%, left our oocyte donation program without obtaining a live birth through this method. The three most frequent reasons for discontinuation were: failure of several oocyte donations (18%), desire of the couples to voluntarily discontinue their care (15%) and separation (14%). Finally, 84 couples obtained at least one live birth by oocyte donation in our center. In addition, 38 women conceived spontaneously and 33 couples benefited from an oocyte donation abroad.

Conclusions: The most common reason for discontinuation in oocyte donation program, excluding live births by oocyte donation in our center, is failure after several oocyte donations. However, 40% of the couples in the study obtained at least one live birth.
