Louise Brown has a lot of company. In-vitro fertilization (IVF) has led to the birth of 5 million people since Brown, the first so-called test tube baby, was born in 1978, a new report says.
Each year now, about 350,000 babies, or 0.3% of the world's newborns, arrive after IVF --- a process in which sperm and egg are joined in a lab dish before the resulting embryo is transferred to the womb -- says a European medical group.
The procedure works about one third of the time.
Some religious groups continue to frown on it.
