Egg Donation

Donation in Spain, according to current Spanish legislation, is anonymous and altruistic. Before a female donor is assigned to a recipient couple, she undergoes a strict battery of tests administered by our multidisciplinary team.

These tests include:

  • Medical, psychological and gynaecological examination
  • Blood tests and serology for infectious diseases
  • Karyotype and a study of her genetic history to rule out the most common hereditary illnesses

The donor then undergoes ovary stimulation to obtain an adequate number of oocytes. The retrieved oocytes are in turn fertilised and days later, when the resulting embryos reach their optimum state of development, are transferred to the recipient mother’s uterus.

At Instituto Bernabeu, the selection of the most suitable donor for each couple is an extremely meticulous process so that facial features and medical characteristics are as close as possible to the recipient mother’s.

In parallel the recipient mother begins a simple and non-invasive therapy which prepares her uterus for the upcoming transfer of the embryos. This preparation is monitored by periodic scans.

Now the In Vitro Fertilisation (IVF) process begins. The retrieved oocytes are fertilised using the male partner’s semen which was previously prepared in the laboratory. If the couple wishes to reduce the time of their stay with us, semen which was previously frozen either at Instituto Bernabeu or in your home country can be used.

Monitoring of embryo development is key in the selection of the best embryos. The embryologists monitor their development and along with the gynaecologist decide the best day for their transfer to the recipient mother’s uterus. As a result of the treatment there are often more than two viable embryos. These remaining embryos can be cryopreserved using vitrification. This is a freezing process which allows the patient to use them for subsequent transfers at a later date.

After embryo transfer pregnancy, birth and lactation will develop normally. After birth, the new-born will be legally recognised as the child of the recipient mother; the same as any other birth.

Success rates per cycle are between 40-70%.

In Europe Instituto Bernabeu is a point of reference for oocyte donation cycles due to our 15 years of experience, our high number of oocyte donors and their sociocultural level.

We can guarantee:

  • No waiting lists
  • Exhaustive medical and genetic testing of all donors
  • Complete compatibility between donor and recipient from a medical standpoint
  • Exclusive assignment of one donor to each recipient which allows a greater number and better quality of oocytes for the donation
  • Meticulous selection process regarding physical characteristics to ensure similarity to the recipient mother
