crotch

The crotch is the region where the lower abdomen and pelvis meet the thighs. In everyday language it is often used to mean the groin or the inguinal area. Anatomists distinguish several related regions, including the groin (the crease at the upper inner thigh), the inguinal region (the area just below the abdomen where the thigh meets the torso), the pubic region (the front of the pelvis), and the perineum (the area between the genitals and the anus). The precise usage depends on context.

In males, the region includes the scrotum and penis, and in females it includes the labia and external parts of the vulva. The skin in this area is typically flexible to allow movement, and it may be covered with hair in adults.

Common health considerations involve the groin and perineal region. Injuries such as groin strains and inguinal hernias are notable in athletes. Skin conditions, dermatitis, fungal infections, and irritation from friction can occur, especially with sweating or tight clothing. Medical assessment for pain, swelling, or lumps in the inguinal region is important, as some conditions require examination or imaging.

In everyday use, "crotch" also refers to the crotch area of clothing, including seams and fabric gussets that accommodate movement. The term is informal and varies by region and age; clinical terminology tends to favor more precise terms such as groin, inguinal region, and perineum.
