Donor Eggs Versus Own Eggs Comparison And Risk Factors

Catherine McDiarmid-Watt | Thursday, May 10, 2007 | 0 comments

The usage of a woman's own eggs or a donor's eggs for ART procedures affects the birth rate.

A woman's chances for a healthy birth using her own eggs, depending on age are 40% in the late 20s, 30% at age 37 and 10% at age 42.

For women using donor eggs the live birth rates are kind of the same. For a woman aging between 30 and 45, the chances for a successful birth when using donor fresh embryos, are around 47%.

The percentage of live birth using fresh, newly fertilized embryos is around 33 while that of fertilization using frozen embryos is 10 points lower. Yet, the frozen embryos might be preferred because this method is less expensive and less invasive for a woman.

The transfer of the embryo and the risk for multiple pregnancy

Increased risk of multiple pregnancy means that more embryos are implanted into a woman's uterus. The same thing also increases the chances for conceiving. A woman aging more than 35, which uses her own eggs for implant, needs more embryos than a younger woman doing the same thing.

The American Society for Reproductive Medicine, which wishes to keep multiple pregnancies to a minimum level, recommends that women under age 35 have no more than three embryos transferred, women age 35 to 40 have no more than four, and women who have had repeated failed cycles or are over age 40 have no more than five embryos transferred. Other researchers recommend no more than two and three in the younger age groups respectively, and encourage doctors to use less than the maximum if a woman's eggs appear to be of good quality.

In the case of women who passed the age of 40, doctors recommend the use of younger donor eggs because their own have a low rate of success.

Before deciding how many embryos to implant in your uterus, the doctor will advice for the best options pending on all the factors involved. You will most likely have this conversation with your doctor before the treatment begins and again before the implantation. In case if more than 2 embryos will be implanted, you will probably be advised on the multi fetal reduction pregnancy to increase the chances for a healthy pregnancy and healthy child

About Catherine: I am mom to three grown sons, two grandchildren and two rescue dogs. After years of raising my boys as a single mom, I remarried a wonderful man who had never had a child of his own. Unexpectedly, I found myself pregnant at 49!
Sadly we lost that precious baby at 8 weeks, and decided to try again. Five more losses, turned down for donor egg, foster care and adoption due to my age and losses - we have accepted that there will be no more babies in our house.
