The Male Reproductive Testis

What Are They?

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

• The are responsible for secreting testosterone and sperm

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.
