crotches

Crotch is an informal term for the region where the legs meet the torso. It overlaps with the groin and the perineal region, and its precise meaning can vary by context. Anatomically, the groin refers to the inguinal area at the junction of the abdomen and thigh, while the perineum is the area between the genitals and the anus.

The region contains skin folds, underlying muscles, and, in males, parts of the reproductive system; in females, vulvar structures. The inguinal region houses the inguinal canal, through which vessels and nerves pass. The perineum includes pelvic floor muscles that support the pelvic organs.

In health, the area supports movement and stability. It is prone to injuries in sports, especially groin strains from rapid side-to-side motions. Inguinal hernias, where abdominal tissue protrudes into the groin, are a common medical issue in adults. Pain in the region can also be due to infections, dermatitis, or nerve irritation such as pelvic or femoral nerve issues.

In clothing, "crotch" commonly refers to the inseam and crotch seam in pants and underwear, with gussets used to improve comfort and durability.

Maintaining dryness, hygiene, and proper fit reduces irritation; seek medical evaluation for persistent pain, swelling, or lumps.
