Success Rates

While proper steps and precautions are always taken in order to help ensure the success of the egg donation procedure, there are often factors that can have an effect on the outcome. Especially at the best egg donor agencies. A thorough screening process is utilized to not only verify that the donor and recipient meet the criteria that is necessary, but to also determine if there are any possible complications to be anticipated.

A thorough medical screening includes the medical history of the recipient and donor, as well as the medical history of their immediate family members. During this screening, cervical cultures and blood is taken to test for diseases or disorders that could affect the procedure or pass on to the recipient.

Age of the Donor

A successful donation occurs when it results in a healthy full-term live birth. There are many factors that contribute to a successful donation, but one of the most important ones is the women’s age. As the age of the donor increases, the success rates can decline with a higher risk of a miscarriage. This can be especially true with donating women over 40 years. Part of the initial criteria to be an egg donor is that the donor is within the specified age range, which is usually in the early 20s and 30s.

Contributing Factors to Success Rates




Other factors that can contribute to the success of a donors eggs are:

  • The successful retrieval of the eggs, without any type of complications.


  • Quality of semen used.


  • The overall health of both the donor and the recipient throughout the entire program.


  • Amount of fertilized eggs that are successfully transferred to the uterus of the recipient. Transferring a larger amount does not increase the chances of success, can increase the possibility of a multiple pregnancy, and is associated with more risk.


  • The age of the recipient is not as big of a factor when it comes to the overall success. However, women in their 50s and older can begin to experience problems.

Increasing Success

canstockphoto1872883Over the past decade, the use of donor eggs has significantly increased with higher success rates for couples who have struggled to become pregnant. It has increasingly become more and more common to successfully deliver a healthy infant that weighs 5.5 pounds or more, which is considered a healthy birth.

Studies have found that couples who elect to receive a single embryo transfer has increased by over 15 percent in the past decade alone. Those recipients who receive frozen embryos, as opposed to fresh embryos, has risen to more than 50 percent, which is compared to nearly 30 percent during past decade.

Many studies continue to confirm that there is a high success rate for couples who previously experienced complications with getting pregnant, carrying a pregnancy to term, or delivering a healthy baby.

The Use of Frozen Embryos

With the many possible factors that can cause an egg donation procedure to be unsuccessful, the use of frozen embryos has become more popular as studies have shown. Many donors produce an excess of eggs, which allow embryos to be frozen. In the event that a pregnancy is not successful, the surplus of frozen embryos permits more opportunities for a successful pregnancy and birth.

While the process of using donor eggs is considered a relatively new procedure, it has been able to successfully help the dreams of thousands of couples come true. As more studies are performed, and technology continues to advance, the success rates of egg donations continues to increase each year.
