Surrogacy Success Rates: What You Can Expect


When considering surrogacy as a path to parenthood, it's natural to wonder about the likelihood of success. However, quantifying surrogacy success rates can be somewhat complex, given that it depends on several factors, including the quality of the eggs and sperm, the surrogate's overall health, the success of the IVF process, and more. Despite these complexities, let's dive into what you can generally expect.

Defining Success in Surrogacy

In the context of surrogacy, 'success' is usually defined as the live birth of a child. However, several milestones typically precede this outcome, each with its success rate. These milestones include the successful retrieval of eggs, fertilization, successful embryo transfer, implantation, achieving clinical pregnancy (confirmed by ultrasound), and ultimately, live birth.

Factors Impacting Surrogacy Success Rates

Several factors can impact the success rates of surrogacy, including:

Age and Quality of Eggs

The age and quality of the eggs used play a significant role in the success of surrogacy. Younger, high-quality eggs are more likely to result in successful fertilization and healthy pregnancy. This is one of the reasons why egg donors are typically young women.

Quality of Sperm

The quality of the sperm used for fertilization is also a significant factor. Sperm health can impact the ability of the sperm to fertilize the egg and the quality of the embryo.

Health and Age of the Surrogate

A surrogate's age and overall health can impact pregnancy and birth success rates. Younger women with no underlying health issues are generally more likely to carry a successful pregnancy.

Success of IVF Procedures

The success of the IVF procedures, including egg retrieval, fertilization, and embryo transfer, also impact surrogacy success rates. The expertise of the medical professionals involved plays a crucial role here.

Average Success Rates

As of my knowledge cutoff in September 2021, statistics from several fertility clinics and surrogacy agencies suggest that the overall success rate of surrogacy - defined as the birth of a child - is relatively high, often exceeding 75%. However, these rates can vary significantly depending on the factors mentioned above.

It's essential to have detailed discussions with your fertility clinic and surrogacy agency about what you can expect given your unique circumstances.
