Embryo selection could become a lot cheaper and allow parents to ensure against diseases (Picture: Shutterstock)

People will stop having sex to procreate within three decades, a US professor claims.

Hank Greely, director of Stanford Law Schools Centre for Law and the Biosciences, believes more parents will end up choosing from a range of embryos created in a lab with their DNA.

Mr Greely believes the process will become a lot cheaper and couples will opt for the method to prevent diseases.

The process involves taking a female skin sample to create stem cells, which are then used to create eggs.

These are fertilised with sperm cells, resulting in a selection of embryos.

Screening would pinpoint any potential diseases and eventually allow parents to determine their childs eye or hair colour.

Mr Greely said: I think one of the hardest things about this will be all the divorces that come about when she wants embryo number 15 and he wants embryo number 64.

I think the decision making will be a real challenge for people.

How do you weigh a slightly higher change of diabetes with slightly lower risk of schizophrenia against better musical ability and a much lower risk of colon cancer? Good luck.

The professor believes the method could cut healthcare costs and reduce diseases.

Mr Greely defended embryo selection despite the murky ethical grounds.

He said: This is not designer babies or super babies. This is selecting embryos.

You take two people, all you can get out of a baby is what those two people have.

There are already concerns that CRISPR, a tool that scientists use to edit DNA, will be used to create perfect embryos.

However, Mr Greely dismissed this as unlikely and said embryo selection will begin as an infertility treatment before expanding.
