Bye Bye Men? Scientists Create Sperm in a Lab

In a world first, scientists have succeed in creating human sperm from embryonic stem cells.

The research is aimed at understanding and overcoming male fertility, but the project has much wider implications. Will two women be able to have their own biological daughter one day?

One of the male tweeters I follow is already scared, heralding the news as sign his species is finished. But there’s no reason to assumepanic stations yet — the team has succeeded only in producing sperm from male embryonic stem cells and producing a baby with the new sperm is illegal in some countries, including Britain.

More practical applications of the artificial sperm are to analyse it for the effect of toxins, such as cancer treatments, which can often cause infertility.
