A groundbreaking global study published on Fertility and Sterility has revealed that over 13 million babies have been born through in vitro fertilisation (IVF) since the first “test‑tube baby” in 1978.
At least 10 to 13 million of these births occurred between 1978 and 2018, with preliminary data from 2018 to 2023 adding another 3 to 4 million, bringing the total to between 13 and 17 million by 2024. Remarkably, today an ART-conceived baby is born approximately every 35 seconds.

The international research team, led by epidemiologist Georgina Chambers at UNSW, analysed data from 101 countries, using a consistent methodology to estimate total ART births despite gaps in registry coverage. Australia, one of the earliest adopters of IVF registries, continues to be a global pioneer in both safety and success rates.
In the UK, IVF has transformed dramatically: success rates for frozen embryo transfers have risen from 7% in the 1990s to 36% in 2021. Meanwhile, over 93% of cycles now involve single-embryo transfers, reducing multiple births to below 3% ScienceAlert.

This study underscores that millions of lives, millions of families, have been touched by IVF. At Plodnost, we are honoured to contribute to this global story of hope and new beginnings.
