Egg Donation

Egg donation is applied to patients that, for a variety of reasons, do not have ovocytes that are capable of producing embryos that develop healthily and satisfactorily. This technique consists of in vitro fertilisation with ova from a donor and sperm from the male and the subsequent transfer of the embryos to the recipient.

It is suitable for older patients, patients with occult ovarian failure, genetic anomalies, multiple abortions, menopause…

Egg donation requires an initial interview including a review of the patient’s clinical and analytical history and explorations required to ensure the transfer process. The recipient is subjected to hormonal treatment to prepare the uterus to receive the embryos. This requires major coordination with the donor in order to achieve positive results. It is not a painful process and does not involve a significant waiting period as the donation programme ensures transfer 3 to 4 weeks following uterine preparation.

Ovum donation is anonymous and legally regulated and it requires the written consent of both parties. The donors must be of legal age, young and healthy, have no genetic diseases and want to help other women to become mothers. Donors are selected according to blood group and requests made by couples with regard to physical characteristics. Currently, this technique is producing gestation in 90% of cases with two embryo transfer cycles and a level of multiple pregnancies below 15%. It is the technique that offers the best results per cycle given that the embryos have great implantation potential due to the age of the donors.
