The genital branch of the genitofemoral nerve (external spermatic nerve) passes outward on the Psoas major, and pierces the fascia transversalis, or passes through the abdominal inguinal ring; it then descends behind the spermatic cord to the scrotum, supplies the Cremaster, and gives a few filaments to the skin of the scrotum.

In the female, it accompanies the round ligament of the uterus, and is lost upon it.
