A groin hernia occurs if contents of the abdominal cavity protrude through the inguinal canal, often perceived as a bulge in the groin. The inguinal canal is a weak spot, containing spermatic cords (men) or the round ligament of the uterus (women). Men are more susceptible to inguinal hernia because the muscles and tendons above the inguinal ligament will get weaker and thinner during their life.
If the protrusion forms below the inguinal ligament, it is called femoral hernia, more common in women. A femoral hernia is sometimes more difficult to diagnose.
Inguinal as well as femoral hernias are groin hernias.
