What Is The Surrogacy Success Rate?

The surrogacy success rate generally refers to the percentage of surrogacy attempts that end in the birth of a healthy baby. Be aware that gestational surrogacy success rates can vary on a case-by-case basis, and each clinic may track this rate differently.

For instance, there can be a large difference when surrogacy success is measured as the likelihood a healthy baby is born once the surrogate is pregnant, which some clinics claim is up to 95%. However, this metric might ignore the handful of unsuccessful embryo transfer attempts before the surrogate became pregnant.

Regulations and oversight of surrogacy reporting can vary widely between states and countries, making it difficult to verify that each clinic is measuring success rates by the same standards. Thus, it can be more useful to track embryo transfer success rates, for which the reporting is more standardized and regulated.

What Is The Surrogacy Embryo Transfer Success Rate?

A joint initiative between the Society for Assisted Reproductive Technology (SART) and the Centers for Disease Control and Prevention (CDC) has standardized assisted reproductive technology (ART) data. This research acts as a reliable benchmark for intended parents who are considering surrogacy and speaking with potential agencies.

According to the most recent CDC data from 2021, the percentage of embryo transfers for patients using donor eggs resulted in live births was 47.0%. Results varied depending on the embryo type, with fresh embryos having success rates as high as 53.5% and frozen embryos having success rates of 46.3%. It is important to note that these statistics are several years old, and success rates vary widely from clinic to clinic. Certain clinics may have substantially higher success rates than the average.

Thus, it’s important to consider the context of embryo transfer success rates through in vitro fertilization (IVF) when discussing overall surrogacy success, as IVF and surrogacy are very much related.

What Impacts Surrogacy Success Rate?

The success rate of surrogacy can depend on a number of factors, including medical, psychological, and logistical aspects. The following are some of the main factors that influence surrogate success rates:

  • The surrogate’s overall health and age
  • The surrogate’s previous pregnancy history
  • The quality of the egg and sperm used
  • The quality of the IVF process
  • The number of embryos transferred

What Are The Requirements To Become A Surrogate?

Women decide to become surrogates for many reasons, though agencies will likely require them to meet certain criteria to ensure they are good candidates. In doing so, they can help protect the surrogate’s health and safety and increase the likelihood of a successful pregnancy.

The exact criteria can vary between agencies, but in general, those who are interested in becoming a surrogate must meet medical, legal, and psychological requirements such as:

  • Living in a surrogate-friendly state
  • Being of a certain age
  • History of healthy pregnancy and delivery
  • No history of significant mental health issues
  • Having a strong support system

What Is A Surrogacy Agency’s Role In Surrogacy Success Rates?

Various elements influence surrogate success rates, from medical factors to the surrogacy agency involved. A surrogacy agency is responsible for matching surrogates with intended parents, coordinating medical and legal services, and supporting surrogates throughout the pregnancy. Hence, the agency’s expertise and support can significantly impact the success rate of surrogacy arrangements.

The IARC advantage is that we offer comprehensive and personalized support at every stage of the program, like helping clients select the right fertility clinic with optimal success rates. We only work with the most highly qualified surrogates and clinics with excellent published success rates and a proven track record serving our clients.
