Could sex become an obsolete way for humans to make babies? It could, according to one expert.
In his new book, Stanford University professor and genetic ethics expert Henry Greely argues that, one day, human reproduction through intercourse could be replaced by scientists creating viable embryos in a lab.

Greedy makes the argument in his recently published book,The End of Sex. He says that in 20 to 40 years when a couple wants a baby, he'll provide sperm and she'll provide a punch of skin.
The skin will become the basis for stem cells to be used in the making of viable eggs.

After fertilisation occurs, he says that parents will be presented with embryos categorised by those with severe diseases, other ailments and appearance-based qualities. A fourth and less predictable grouping could be by behavioural characteristics.
However, once the embryo is selected, it would still be implanted in the mother, who would carry the foetus and deliver the baby as usual.
In his book, Greely predicts that this scientific methods of reproduction will not only be easy, safe and inexpensive, but it will also be legal.
