There are many reasons why a woman may be unable to produce eggs including genetic diseases, chemotherapy and unexplained infertility. But age is certainly a key contributing factor. By the time a women reaches her 40th birthday, adoption or egg donation may be her last remaining options.

Egg donation has revolutionised fertility for older women whose egg reserve has diminished in both quality and quantity,” says Dr David Walsh of the SIMS Clinic.

“Every third patient of mine is using donor sperm, donor eggs or both.” The good news is that egg donation gives women a high probability of success. The success rates of egg donation are similar to that of IVF. More than half of the patients using this form of treatment should get pregnant within two major cycles. “This will vary from woman to woman because some people will get more embryos than others,” explains Dr Walsh. “The more embryos you obtain from the treatment, the greater number of chances you have of success. Beyond two rounds, it becomes increasingly unlikely that the treatment will result in a baby.

“Another reason for success is where donors have proven fertility with children of their own. We therefore know their

eggs are capable of reaching pregnancy. Secondly, research has shown that if donors have their own family they are much less likely to regret their decision further down the line.”

That said deciding to pursue the egg donation route is a big decision for couples – and not something to be undertaken lightly.

It is the classic dilemma. Your heart tells you that you want to be the genetic mother of this child, but your head tells you that you've got poor quality embryos and that you are likely to fail using your own eggs. But by introducing a third party into the treatment process, there will be a lot of very difficult questions to address.

Couples need to ask themselves how they feel about using a donor egg, who will they tell, and how will they address this matter with the child in the future.

Known versus anonymous donors

“I saw a patient today who is very lucky because her sister is not only able, but very willing to, donate her eggs to her,” continues Dr Walsh. “That is the ideal circumstance when going down this route.”

That said most women do not find themselves in this situation so they have to go to a third party for donation. In this instance a couple will come in for a consultation and if all of their tests work out properly the male will freeze a sample of his sperm. That sample is then shipped to the Ukraine or Czech Republic, the donor’s eggs are collected and the embryos are created.

The embryos are then frozen on day one before they start to divide. They are shipped back to the Irish clinic where they are thawed in the laboratory and transferred to the female’s womb.


Recently, the Irish government has announced a plan to publish legislation which is likely to end the use of anonymous donor eggs or sperm.

This is on the recommendation of the Commission on Assisted Human Reproductions, who, in 2005 stated that children of donor eggs or sperm should have a right to information about their donor parents upon reaching maturity.

While the introduction of the legislation will no doubt grant children who have been born out of donor eggs and donor sperm more options and should completely eliminate the chance of incest occurring it brings its own set of challenges.

The problem is that this legislation could limit the supply of donors and create larger waiting lists. This is because there are far fewer identifiable donors available in this country.

While couples can still secure donor eggs and sperm abroad, the legislation will cause the cost of the treatment to increase for couples.

“Rather than embryos coming to couples, couples will now have to fly to the country where the eggs or sperm are being donated to complete the treatment. It adds an extra cost for the couple,” says Dr Walsh.

“The good thing is the patient will still have access to the treatment they need but I feel that they are being singled out and discriminated against in some ways. The barrier for those trying to have a baby with fertility problems is always set so much higher than for anyone else.”
