What Is an Inguinal Hernia?

In an inguinal hernia, a loop of intestine or another abdominal organ pushes through an opening in the abdominal wall into the inguinal canal. The inguinal canal contains the spermatic cord, which consists of the vas deferens, blood vessels, nerves, and other structures. Before birth, the testes, which are formed in the abdomen, pass through the inguinal canal as they descend into the scrotum.
