During development, the testes in the male pass through the inguinal canal, a passage through the abdominal wall
musculature, to enter the scrotum. High pressures in the abdominal cavity assist in pushing the testes into the
scrotum, and later can also push other abdominal contents into the inguinal canal. Similar hernias can occur in
females; however, they are less frequent because the inguinal opening is less likely to remain open to the degree it
must in males, around the passage of the sperm cord.
