What Are They?
• Two glands that are suspended within a sac that hang outside of the body called the scrotum.

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.
