Men with infertility might be more likely to develop prostate cancer than men who are fertile, a recently published study in the BMJ suggests.
Previous studies investigating the connection between male infertility and prostate cancer risk have had mixed results.
One reason for the conflicting findings could be the different ways researchers defined infertility. In some studies, childless men were compared with men who had fathered children, whereas in other studies, men with impaired semen quality were compared with those with normal semen quality. However, some men are childless by choice or because their partners have infertility, whereas some men with impaired semen quality father children with the help of assisted reproductive techniques.
