Oocyte Donation / Egg Donation


When a woman has lost her ovaries, or her ovaries do not contain any more oocytes, a pregnancy can still be achieved using donor oocytes.

The process involves extracting oocytes from a compatible donor’s ovary. The eggs are taken to the laboratory where, under strict laboratory conditions they are fertilized with the sperm of the receptor’s husband.

After 2 or 3 days the fertilized eggs (now 4 or 8 cells embryos) are placed directly into the uterus of the receptor to be implanted and proceed with the a normal pregnancy.

Who benefits from oocyte donation?

What is the probability of getting pregnant with this treatment?

Women who:

  • Have lost their ovaries due to surgery or other causes.
  • Have a genetic disease they do not want her children to inherit.
  • Are menopausal.
  • Have had fertilization failures due to ovarian factors

Oocyte donation is one of the most effective treatments, with pregnancy rates around 60% per cycle.

What is needed before starting a oocyte donation cycle?

The couple needs to have an interview with one of the doctors to assess general health, the uterus and the quality of the sperm.  A meeting with the psychologist is done to help couples to identify possible areas of conflict and cope with them.

Also, the couple needs to do a blood test for AIDS, hepatitis B and C.
