<prompt> The efferent limb of cremaster reflex is carried byFemoral branch of genitofemoral nerveGenital branch of genitofemoral nerveIlio-inguinal nervePudendal nerve  <response>: CREMASTER REFLEX: When we touch upper medial thigh in males, cremaster muscle contracts pull the ipsilateral testicle towards inguinal canal. Afferent sensory information is carried by Femoral branch of Genitofemoral N. Ilioinguinal N. towards spinal cord at level of L1 Efferent motor signal- Genital branch of Genitofemoral N. towards cremaster muscle to elevate the scrotum. Iliohypogastric Nerve L1: Supplies skin above inguinal ligament Ilioinguinal Nerve L1: Supplies skin of anterior scrotum and adjacent thigh Genitofemoral L1, L2: Supplies skin below inguinal ligament, motor to cremaster muscle Note: Both the ilioinguinal nerve and genital branch of the genitofemoral nerve pass through the inguinal canal.
