Contrary to popular belief, miscarriage is not always prompted by a female health issue. Sperm can have an influence on recurrent miscarriage. The presence of an abnormal chromosome can cause miscarriage and this may come from the male partner’s sperm. Therefore it is important that the male partner is also investigated if a couple has experienced recurrent miscarriages in the same way that male fertility should also be investigated if a couple are having difficulty conceiving.
