In vitro fertilization (IVF) has transformed family building over the past four decades, and new research shows just how far it has come. A recent study published in Fertility and Sterility estimates that between 10 and 13 million babies were born through IVF between 1978, when the first IVF baby was born, and 2018. With preliminary data suggesting an additional 3 to 4 million births since then, the total number of IVF-conceived babies in 2024 is likely between 13 and 17 million. 

That means today, one baby conceived through assisted reproductive technology (ART) is born approximately every 35 seconds.

This study, the first of its kind to provide a consistent global estimate, shares the rapid growth of IVF and its place in modern family-building. Once considered groundbreaking, IVF is now a widely used medical treatment that helps individuals and couples around the world overcome infertility.

A Global Snapshot of IVF

The research was conducted using 40 years of data collected by the International Committee Monitoring Assisted Reproductive Technologies (ICMART). It shows that IVF is most commonly used in high-income nations where public funding, medical infrastructure, and regulations make treatment more accessible. Countries like Australia have played a pioneering role in IVF’s development, becoming leaders in both safety and success rates. For instance, Australia was the third country to deliver an IVF baby in 1983 and the first to establish a national IVF registry.

Today, one in 16 babies in Australia is born via IVF, and that figure rises to one in 10 for women over 35. These achievements are in part due to advancements such as single embryo transfers and improved freezing techniques, which have significantly reduced the risk of multiple births while maintaining high success rates.

Access and Equity

Despite these advancements, the study also points out the stark disparities in access to IVF. In many low and middle-income countries, IVF remains out of reach due to high costs, limited infrastructure, and a lack of public support. While some governments now provide funding for IVF to address declining birth rates, experts caution that fertility treatment should primarily be recognized as medical care for those struggling with infertility, not simply as a population growth strategy.

Looking Ahead

While IVF has helped millions achieve parenthood, it has its limitations. Success rates decrease with age, with live birth rates per cycle dropping significantly for women over 35. This highlights the importance of education about fertility and societal support for people to pursue family-building earlier if they wish.

The remarkable growth in IVF births reflects not just medical innovation, but also the evolving understanding of reproductive rights and family structures. As access expands, the hope is for equitable, high-quality care to become available to all who need it, regardless of geography, income, or family type.
