U.S researchers have developed a new method for selecting the best sperm during IVF treatments.
According to the team from Yale University, the method is as effective as the egg's own natural selective ability.
The technique selects the sperm with the highest DNA integrity and could be used to boost male fertility.
Senior study author, Dr Gabor Huszar, said: 'Our results could help address the fact that approximately 40 per cent of infertility cases can be traced to male infertility.'
Dr Huszar said that past semen analysis focused on sperm concentration and mobility. It was assumed that a man was fertile if he had a high sperm count and active sperm.
However, there was no information on the sperm’s fertility or its ability to attach to its mark - the female reproductive cell.
