Establishing a Donor Oocyte Cryobank Network: European Experience

According to data from different surveys, gamete donation treatments are on the rise and are already allowed in most countries of the world (The European IVF-Monitoring Consortium for ESHRE, et al. Hum Reprod Open 2020:1–26, 2020). Implementation of the vitrification technique for oocyte cryopreservation has resulted in an improvement in oocyte survival rates, enabling the successful banking of oocytes. This facilitates improved logistics of treatment for the MAR centers, but it also enables the distribution of cryopreserved oocytes.
