5 mn test tube people exist in world

An estimate that is released recently has stated that since the world had its first test-tube baby, in-vitro fertilisation (IVF) has given the world about five million new people. And it was about 34 years back when world had its first IVF baby in England.

According to the European Society of Human Reproduction and Embryology (ESHRE), every year about 350,000 babies that are conceived in petri dishes are born.

And this makes an annual addition of about 0.3 percent of the 130-million-odd babies added to the world.

David Adamson, chairman of the International Committee for Monitoring Assisted Reproductive Technologies (ICMART) said, "Millions of families with children have been created, thereby reducing the burden of infertility."

In the IVF technique a petri dish is used for placing an egg and sperm together for conception, and a sub-category known as ICSI (intracytoplasmic sperm injection) is used for putting a sperm into an egg which is directly inserted using a micro-needle.

But over the years this has gathered a lot of controversies. People say that babies are designed this way in which parents can choose the characteristics of the babies.

The procedure has attracted criticism because this allows women to bear children for a longer time and a large number of embryos also get wasted in this procedure.
