Last Call

Scientists have succeeded in making sperm cells out of stem cells in lab conditions, and the process could be used to help infertile couples.

The breakthrough could give hope to infertile couples and men left unable to have children after having cancer treatment.

But don't worry guys, the scientists who created the sperm using stem cells don't plan to take you out of the baby-making process just yet.

While we can understand some people may have concerns, this does not mean that humans can be produced in a dish and we have no intention of doing this,' said researcher Prof Karim Nayernia.

'The work is a way of investigating why some people are infertile and the reasons behind it.

'It could also allow men who are currently infertile the chance to have a child which is genetically their own but this will be many years away – at least a decade.'

For now, we'll have to settle for the technique being used as a plot device in movie comedies about lesbians wanting kids.
