Regions of the Testis
Homeostasis The testis remain outside the body to retain the perfect temperature for sperm production, which is slightly lower than the body temperature. Raise and Lower Reflex Reaction
Hormones FSH (follicle-stimulating hormone) The development, growth, pubertal maturation, and reproductive processes of the body LH (luteinizing hormone) Stimulates Leydig cell production of testosterone
Sperm Production FSH acts directly on the Seminiferous tubule to produce sperm Immature sperm travels from the seminiferous tubules to the epididymis where is stays until sexual arousal. http://health.howstuffworks.com/sexual-health/male-reproductive-system/adam-200126.htm
