This is the most common hernia(about 70% of all hernias are inguinal hernias). They occur in the groin, the small area of the lower abdomen on each side just above the line separating the abdomen and the legs, and around the pubic bone.
They occur through the inguinal canal, a conduit where the testicle comes through on its way to the scrotum during the development of males. Men and women develop from the same basic pattern so there are anatomical similarities between men and women, meaning that women also have the inguinal canal. But in women the inguinal canal is much much smaller, and as a result inguinal hernias are much more uncommon than in men.
