Male Reproductive System

Question 1

is the loose, pouch-like sac of skin that hangs behind the penis. It holds the testicles (testes) as well as nerves and blood vessels. Protects the testicles and provides a sort of “climate-control system.”

Answer 1

Scrotum

Question 2

Make testosterone and produce sperm. Oval-shaped organs that lie in your scrotum. They’re about the size of two large olives. The spermatic cord holds the testicles in place and supplies them with blood.

Answer 2

Testicles

Question 3

Within the testicles are coiled masses of tubes. Produce sperm cells through spermatogenesis.

Answer 3

Seminiferous tubules

Question 4

is a long, coiled tube that rests on the back of each testicle. It carries and stores the sperm cells that your testicles create. This also brings the sperm to maturity — the sperm that emerge from the testicles are immature and incapable of fertilization. During sexual arousal, muscle contractions force the sperm into the vas deferens.

Answer 4

Epididymis

Question 5

is a long, muscular tube that travels from the epididymis into the pelvic cavity, just behind the urinary bladder. It transports mature sperm to the urethra in preparation for ejaculation.

Answer 5

Vas Deferens

Question 6

is the tube that carries pee from your bladder outside of your body. If you have a penis, it also ejaculates semen when you reach orgasm.

Answer 6

Urethra

Question 7

are sac-like pouches that attach to the vas deferens near the base of the bladder. Make up to 80% of your ejaculatory fluid, including fructose. Fructose is an energy source for sperm and helps them move (motility).

Answer 7

Seminal Vesicles

Question 8

is a walnut-sized gland that rests below your bladder, in front of your rectum. This adds additional fluid to ejaculate, which helps nourish sperm. The urethra runs through the center of the this gland.

Answer 8

Prostate
