The statement "Hernias are more common in men because when the testicles descend through the inguinal canal, the opening of the canal does not close completely" is generally true. Hernias are more common in men due to the presence of the inguinal canal, which allows the descent of the testicles during fetal development. In some cases, the opening of the inguinal canal may not close completely, leaving a potential weak spot in the abdominal wall. This can increase the risk of hernias in men. However, it's important to note that hernias can also occur in women, albeit less frequently, due to other factors such as pregnancy and childbirth.
