Branches
Genital branch
The genital branch continues downward on the surface of the psoas major muscle, then enters the
In men, the genital branch supplies the cremaster and scrotal skin. In women, the genital branch accompanies the round ligament of uterus, terminating in and innervating the skin of the mons pubis and labia majora.[1]
Femoral branch
The femoral branch passes underneath the inguinal ligament, travelling through the lateral muscular compartment of the femoral sheath where it innervates skin of the upper leg. Passing through the cribriform fascia of the saphenous opening of the fascia lata of the thigh, it then supplies the skin of the upper, anterior and medial side of thigh.[1]

The genitofemoral nerve is formed in the midsection of the psoas muscle by the union of branches from the anterior rami of L1 and L2 nerve roots
Function
The genitofemoral nerve is responsible for both the sensory (femoral branch) and motor portions (genital branch) of the
