In human anatomy, groin refers to the structure located between abdominal pain bone and thigh root and in femoral groove. This structure is mainly composed of four muscle groups (iliopsoas, rectus femoris, latissimus femoris and femoral hernia) and peritoneum, which is the junction of abdominal wall muscles and thigh muscles.

The groin has an important physiological function in the human body. First of all, the groin is an important meeting point of human lower limbs, where muscle groups can coordinate and undertake the transfer and effective distribution of energy in the body. Secondly, in walking, running and other physical activities, groin muscles can effectively strengthen the support and stability of the waist and pubic region by assisting the peritoneum and iliopsoas muscles. In addition, the groin is the supporting structure of male spermatic cord, which has a certain protective effect on male reproductive function.

The groin is prone to pain and discomfort. Common diseases include ilitis, femoral hernia and so on. In order to reduce groin pain and discomfort, preventive measures are very important. It is recommended to pay attention to a healthy diet, exercise regularly, avoid long-term weight-bearing or strenuous exercise, try to avoid accidental injuries such as muscle strain, and seek medical advice in time when obvious symptoms appear. Regular massage and fitness exercises in the groin area can also help prevent groin pain and discomfort.
