Five million babies have been born worldwide thanks to assisted reproductive technologies. The figure comes from the International Committee for Monitoring Assisted Reproductive Technologies, an independent, nonprofit organization that collects and disseminates world data. They presented their estimates of successful births resulting from IVF treatments at the annual meeting of the European Society of Human Reproduction and Embryology on Sunday. The 5 million estimate is based on the number of IVF treatment cycles recorded worldwide up to 2008, with estimations added for the following three years. The world’s first baby conceived outside the womb was Louise Brown, who was born in 1978.
