The male groin is located at the junction of the lower abdominal and thigh walls, with the inner, upper, and lower lateral boundaries being the outer edge of the rectus abdominis muscle, the horizontal line passing through the anterior superior iliac spine, and the inguinal ligament, respectively. The location of the inguinal region in males and females is the same, both located at the junction of the lower abdominal wall and the thigh, but in males the inguinal region has the spermatic cord passing through the inguinal canal, which is different from the round uterine ligament in females, and males are more prone to inguinal hernias. The inguinal region is a triangular area at the junction of the thigh and lower abdomen, symmetrical on both sides. The inguinal region is bounded medially by the outer edge of the external oblique muscle, superiorly by the horizontal line passing through the anterior superior iliac spine to the outer edge of the rectus abdominis muscle, and inferiorly by the inguinal ligament. The inguinal region includes the inguinal canal and the inguinal triangle (Hay’s triangle), which is where inguinal and rectal hernias occur. Patients with abnormalities in the inguinal region are advised to seek prompt medical attention and follow medical advice for examination and treatment.
