Surrogacy is an increasingly popular path to parenthood, but the decision often comes after understanding key statistics about fertility, success rates, and the surrogacy journey itself. In this article, we’ll dive into the numbers and explore the realities behind human fertility, surrogacy success rates, and what these statistics mean for intended parents considering this path.

1. The Reality of Human Fertility
Human fertility rates have been declining worldwide. On average, a healthy couple has about a 20-25% chance of achieving pregnancy each month when trying naturally. However, various factors like age, genetics, lifestyle, and underlying health conditions can drastically reduce these odds. By the age of 35, a woman’s chances of conceiving naturally drop to around 15%, and by 40, it’s less than 5%. This steep decline in fertility is one of the driving forces behind the increasing demand for assisted reproductive technologies (ART), including surrogacy.
2. Surrogacy Success Rates: What the Numbers Say
Surrogacy offers hope for those facing infertility challenges, but it’s essential to understand the realistic outcomes. Success rates can vary significantly depending on factors like the age and health of the egg donor, the quality of embryos, and the experience of the clinic handling the process.
Gestational Surrogacy Success Rates: According to recent studies, gestational surrogacy has a success rate of around 70-80% per embryo transfer when high-quality embryos are used. This is considerably higher than natural conception odds, making surrogacy a viable solution for many intended parents.
Embryo Quality and Genetic Testing: Embryo quality plays a pivotal role in surrogacy success. Embryos are graded based on criteria like cell division, symmetry, and overall health. Additionally, preimplantation genetic testing (PGT-A) can help identify chromosomally normal embryos, improving the chances of a successful pregnancy and reducing the likelihood of miscarriage.
3. Human Subfertility and the Role of Assisted Reproductive Technology (ART)
It’s often said that humans are naturally subfertile, meaning our species has a lower rate of successful conception compared to other animals. ART has become essential in addressing this subfertility. In fact, over 8 million babies have been born worldwide through IVF and other assisted reproductive technologies.
Surrogacy adds another layer of support for those who cannot carry a pregnancy themselves, either due to medical conditions, previous failed IVF cycles, or being part of the LGBTQ+ community.
4. Surrogacy by the Numbers: Global and Regional Insights
Globally, surrogacy continues to grow, with thousands of surrogacy births reported each year. In the U.S. alone, it’s estimated that between 750 to 1,000 babies are born via gestational surrogacy annually. Colombia is quickly becoming a preferred international destination for surrogacy due to its legal framework and affordability, with many international intended parents choosing the country for its blend of high-quality care and lower costs.
5. The Importance of Age and Surrogate Screening
The age of the egg donor and surrogate is one of the most critical factors influencing success rates. Clinics typically prefer egg donors aged between 21 and 30, where egg quality is highest. Surrogates, on the other hand, should ideally be under 38 years old and must have had at least one successful pregnancy. Comprehensive medical, psychological, and genetic screening is performed to ensure that both donors and surrogates meet these criteria.
6. The Cost Factor: How Surrogacy Programs Compare
Surrogacy can be financially overwhelming, especially in countries like the U.S., where costs can exceed $150,000. However, in countries like Colombia, surrogacy programs are significantly more affordable, often costing less than half the price, making it accessible to a broader range of intended parents without compromising quality.
Final Thoughts: What the Statistics Mean for You
While surrogacy statistics provide valuable insights, it’s important to remember that every journey is unique. Success rates are influenced by a wide range of factors, and working with an experienced and compassionate team is key to navigating this process. Understanding the numbers helps set realistic expectations, but the true measure of success is building the family you’ve always dreamed of.
