Egg donation

When a woman does not have enough quality eggs, or when a fertility treatment does not succeed, we recommend to receive the eggs from a donor. The donated eggs are fertilised with the sperm of the man. Then we will implant the embryo in the uterus of the woman.

Egg donation process

1. Previous study of the couple. The first appointments are an essential part of the treatment, so we can understand your personal situation in order to adjust our methods and procedures to your own needs. We will perform only the strictly required tests for you, and they will be given with the suitable prescriptions and written instructions.
2. Sperm testing and freezing: it will be performed during the first medical appointment.
3. Uterus preparation by treatment. If you do not leave near any Cefer centre, you can undergo this treatment in your city.
4. Ultrasound exams for the preparation of the endometrium: which will confirm that you can receive the embryos. They will be transferred to your uterus from 3 to 5 days after the retrieval of the eggs.
5. Intracytoplasmic sperm injection: we inject the sperm into the donated eggs.
6. After 20 hours, we will be able to observe if the eggs have been fertilised.

We can transfer from one to three emrbyos at most, as the current Spanish law says. Our medical team will be at your side during the process. We will answer any questions you may have about the process.
