“More than 10 million children have been born worldwide thanks to IVF since the birth of Louise Brown on 25 July 1978. Brown was the first person to be conceived using the technique following more than a decade of research, an achievement that features in the film Joy – named after Brown’s middle name.
This revolutionary infertility treatment is now responsible for about 2% of all births in the US annually. Plus, the live birth rate for IVF cycles has been getting steadily better over the years – roughly tripling for women under 38 since the early 1990s, according to UK data. In the US, the number of live births resulting from assisted reproductive technology – IVF accounts for 99% of such procedures – are 1.6 times higher in 2020 than they were a decade earlier.
And yet the live birth rate, per embryo transfer cycle, for women aged 35 or so is still just 30% in the UK and 39% in the US. In women of all ages, only 45% of embryo transfer cycles led to a live birth in the US, although that has grown from 36% in 2011…
Scientists around the world are trying to help by working on techniques that might improve the odds of success.”
