In human anatomy, the genitofemoral nerve originates from the upper part of the lumbar plexus of spinal nerves. Its roots are L1 and L2 (lumbar).
It descends laterally through the psoas major muscle and divides into two branches:
- The femoral branch, or lumboinguinal nerve, supplies skin anterior to the upper part of the femoral triangle
- The genital branch:
- in males, it travels through the spermatic cord and supplies the cremaster and the scrotal skin
- in females, it ends in the skin of the mons pubis and labia majora
