Global Count of IVF Births Exceeds 13 Million

A comprehensive study estimates that more than 13 million babies have been born worldwide through assisted reproductive technology (ART) since the advent of in vitro fertilization (IVF). Revealing that an IVF-conceived infant is born approximately every 35 seconds, this milestone underscores the significant role of reproductive technology in modern family building. The research, published in the journal Fertility and Sterility, analyzed data from 1978 to 2018, capturing the number of children born via IVF over the past four decades. It highlights that between 10 and 13 million IVF babies were born during this period, a figure that surpasses half of Australia's population, illustrating the global scale of ART's impact.

Professor Georgina Chambers, a lead author and director of UNSW's National Perinatal Epidemiology and Statistics Unit, explains that previous estimates relied on annual averages, but this study used a consistent methodology and extrapolated missing data, providing a clearer picture of IVF's growth. The study suggests that by 2024, the total number of IVF births could be between 13 and 17 million, with preliminary data indicating continued exponential growth.

Australia played a pioneering role in IVF development by being the third country to deliver a successful IVF baby in 1983. Thanks to early innovations and rigorous data collection through the Australian and New Zealand IVF registries, Australia now accounts for roughly 1 in 16 babies being born through IVF, and nearly 1 in 10 among women over 35. Globally, IVF's adoption varies; high-income countries like Australia benefit from government support and regulation that enhance access, unlike many low- and middle-income nations where infrastructure and funding gaps limit availability.

The study also examines how IVF practices differ worldwide. In Australia and other developed nations, single embryo transfers are now standard, reducing multiple birth risks, with over 93% of cycles involving one embryo. However, in many parts of the world, higher rates of multiple births persist due to different treatment protocols.

While IVF significantly assists individuals and couples facing infertility, experts caution against viewing it as a solution for reversing demographic declines. The data indicates that IVF has a limited impact on overall fertility rates, especially considering declining egg quality with age and the reduced success rates for women over 35. Fertility awareness and broader policies supporting family-building when individuals are ready are more effective strategies.

Behind each IVF birth is a deeply personal journey, and the increasing number reflects the procedure's societal importance. Prof. Chambers emphasizes that access to fertility treatments should be a human right, striving for more equitable availability worldwide. While IVF can help offset infertility, it does not significantly alter fertility trends caused by societal and biological factors, including women delaying childbirth. The goal remains to provide respectful, equitable, and accessible reproductive healthcare for all.
