The egg-donation program is an assisted reproductive technique in which a female donor supplies a female gamete (oocyte) to be implanted in a woman who wishes to give birth.

Anonymous women who meet a series of requirements (e.g., age, state of health) give their eggs over so that other women who have difficulty conceiving may have a chance at motherhood.

What does it involve?

According to Spanish law, egg donors must be adult women under the age of 35 who are in an appropriate state of physical and mental health and with no genetic risk factors or infectious diseases. In addition to these requirements, our egg donors must undergo an overall gynecologic examination and a complete hormone panel and genetic study to ensure that they are appropriate candidates for follicular stimulation and that the procedure will not put them at risk.

Donors must follow a series of follicular-stimulation protocols and adhere to certain oocyte-collection guidelines for conventional IVF.

When is it recommended?

  • Ovarian failure: inability to produce eggs.
  • Poor response to assisted reproductive treatments.
  • Repeated IVF failure: In these cases, the ovaries respond appropriately, producing more than three mature oocytes, but no successful pregnancy is attained despite a sufficient number of IVF cycles (normally 3 or 4).
  • Advanced age.
  • Serious genetic abnormalities that may affect a mother's offspring.
  • Repeated miscarriages.

How effective is it?

Egg donation normally has a higher success rate than other assisted reproductive techniques.
