2. allows passage of semen; 3. provides sensation (has many nerve endings) ***Urine or sperm passes through the penis in a small tube called the urethra.


6 FORESKIN Foreskin is the skin covering on the tip of the penis. It is a parent’s choice to remove the foreskin or keep it on. It is completely normal either way.

7 SCROTUM Skin covered sac that hangs from body What it does:
1. Holds testicles 2. Regulates temperature of testicles Brings the testicles closer to the body when cold Drops the testicles lower when warm 3. Provides sensation

8 TESTICLES What does it do: 1. Produces SPERM 2. Produces TESTOSTERONE

9 TESTOSTERONE 1. Facial and body hair to grow 2. Deepening of voice
Testosterone causes: 1. Facial and body hair to grow 2. Deepening of voice 3. Broadening of shoulders 4. Influences sperm production

17 COWPER’S GLAND Also known as Bulbourethral (Bulb-o-urethral) Glands
Provides CLEAR fluid that: Cleanses urethra of acid to protect sperm
