In-vitro fertilization births now over 5 million

Over five million babies have now been born using in-vitro fertilization.

Fertility experts made the announcement this week at a conference in Turkey.

The first in-vitro baby was born back in 1978.

Now, about 350,000 babies worldwide are conceived in petri dishes every year.

Researchers say Europe is the most active region for in-vitro, accounting for about a third of all procedures done around the world.
