Hernias above the abdominocrural crease are inguinal (latin, groin) and those arising below the crease are femoral (Latin, thigh) or crural (Latin, leg).

None. But there are two types of inguinal herniae (or hernias): direct and indirect. Direct inguinal hernias occur when abdominal contents herniate through a weak point in the fascia of the abdominal wall and into the inguinal canal. Indirect inguinal hernias occur when abdominal contents protrude through the deep inguinal ring; this is ultimately caused by failure of embryonic closure of the processus vaginalis.
The majority of hernias occur in males. Nearly 25% of men and only 2% of women in the United States will develop inguinal hernias. Inguinal hernias occur nearly three times more often in African American adults than in Caucasians.
Inguinal hernias have the greatest potential for herniation as they are the most common type of hernia and occur in the groin area where there is a natural weak spot in the abdominal wall. If left untreated, inguinal hernias can lead to serious complications such as incarceration and strangulation.
Inguinal hernia
The region surrounding the crease in the skin at the junction of the upper leg with the trunk is called the inguinal region. This area is important for lymphatic drainage, blood vessels, and nerves that supply the lower limbs. It is also a common site for hernias to occur due to the natural weakness in the abdominal wall in this area.
Organs that come out of the body are typically referred to as protrusions or hernias. Hernias occur when an organ pushes through the muscle or tissue that holds it in place, often causing a visible bulge under the skin. Inguinal hernias are one common type that can appear in the groin area.
The common name for the inguinal region is the "groin." This area is located where the abdomen meets the thigh and is significant in both anatomy and clinical contexts, as it is a site where hernias can occur. The inguinal region is also important for various structures, including blood vessels and nerves that supply the lower limb.
The bilateral abdominocrural creases are located where the abdomen meets the thighs. They are the natural creases or folds that occur at this junction due to the different skin tension and movement in these areas.
The type of hernia that commonly accompanies cryptorchidism is an inguinal hernia. This occurs because both conditions are related to the developmental processes in the groin area during fetal growth. Inguinal hernias are more prevalent in males and can occur when abdominal contents protrude through the inguinal canal, which may also be involved in the descent of the testes. The presence of a cryptorchid testis can increase the risk of an inguinal hernia due to the incomplete descent of the testis into the scrotum.
Both men and women can get hernias the same way, a weak place in the muscles of the wall of a body cavity splits and allows the cavity contents to protrude. Hernias involving the abdominal cavity are common in men and women. They can happen any place in the abdominal wall muscles. They are called ventral hernias. A type more common in men, but also seen in women, occurs in the groin area called the inguinal area on either (or both) sides of the low abdomen and are called inguinal hernias. These frequently show up after a heavy lifting strain and protrude/"rupture". A lump may appear in the area with the pain which is actually a portion of bowel protruding through the muscle opening. In men, inguinal hernias may not show a lump in the inguinal area if the area of weakness is at the bottom and bowel slips into the scrotum and protrudes there as a lump in the scrotum. Other common places in the abdominal cavity wall that can "rupture" are in the area around or near the belly button, which are called umbilical hernias, or at an incision site from a previous surgery called incisional hernias.
There is a wide varieties of hernias that can occur on many places of the body, both in children, women, young and elderly men.
Femoral hernias are a relatively uncommon type, accounting for only 3% of all hernias. While femoral hernias can occur in both males and females, almost all of them develop in women
