Damaged sperm could be to blame for repeated miscarriages

Imperial College scientists find DNA damage in sperm could be undetected cause

Men should undergo tests when couples suffer repeated miscarriages, according to researchers who say the health of the man's sperm may sometimes be a factor.

The focus is usually on the woman's body when multiple pregnancies fail, with tests usually looking for immune system problems or infection. But a small government-funded study by scientists at Imperial College London suggests miscarriage could also be a result of male issues, particularly if they are not routinely tested.
