Male Reproductive System

Male Gamete: Sperm

2. Gonads (testes) Produce sperm and testosterone Testosterone: hormone that give a male secondary sex characteristics (deep voice, facial hair, etc.)

Puberty Age when secondary sex characteristics appear

1. Scrotum Sac that holds testes outside the body wall. This provides a lower temperature for sperm production.

3. Epididymis Area that stores sperm in the upper part of the testes. Area where sperm matures

4. Vas Deferens Tube that carries sperm out of the testes Vasectomy – procedure where the Vas Deferens are cut to prevent sperm from leaving the body. Method of preventing pregnancy.

10. Urethra Tube that joins with the Vas Deferens Carries sperm and urine out of the body.

7. Seminal Vesicles Gland that secretes fructose (sugar) which provides energy for sperm

9. Prostate Gland Secretes an alkaline (basic) substance. This neutralizes the acid in the environment that is harmful to sperm. Produces semen to nourish and carry the sperm.

Fluids That Help Transport Sperm Semen – mixture of fluid and sperm The fluid in semen provides a watery environment for sperm to move.

5. Bulbourethral Gland Secretes fluids that protect the sperm

11. Penis Has some bone tissue, so it can be fractured. This is why male athletes wear a cup. Ejaculation- Process that moves sperm out of the urethra

Spermatogenesis
