Domain 1: Male Reproductive Anatomy & Physiology
1. The primary function of the testes is to:
A) Produce testosterone and spermatozoa (sperm).
B) Store mature sperm.
C) Transport sperm to the urethra.
D) Produce seminal fluid.
Answer: A
Rationale: The testes (gonads) have two primary
functions: spermatogenesis (production of sperm)
and steroidogenesis (production of testosterone, the primary male sex hormone).
2. The site of sperm maturation and storage is the:
A) Seminiferous tubules.
B) Epididymis.
, Page |2
C) Vas deferens.
D) Ejaculatory duct.
Answer: B
Rationale: The epididymis is a coiled tube located on the posterior surface of each
testis. It is the site where sperm undergo maturation (developing the ability to
swim and fertilize an egg) and are stored until ejaculation.
3. Which of the following accessory glands produces the majority of the seminal
fluid (approx. 60-70%) that nourishes and protects sperm?
A) Prostate gland.
B) Seminal vesicles.
C) Bulbourethral (Cowper's) glands.
D) Epididymis.
Answer: B
Rationale: The seminal vesicles produce a thick, alkaline fluid rich in fructose
(which provides energy for sperm) and prostaglandins. This fluid constitutes
approximately 60-70% of the total semen volume.
4. The prostate gland secretes an alkaline fluid that:
A) Provides energy for sperm.

B) Neutralizes the acidity of the vaginal tract, thereby increasing sperm motility
and survival.
C) Lubricates the urethra.
D) Stimulates the release of FSH.
Answer: B
Rationale: The prostate gland secretes a thin, milky, alkaline fluid that neutralizes
the acidic environment of the female vagina, which is essential for sperm survival
and motility.
5. The duct that transports sperm from the epididymis to the ejaculatory duct is
the:
A) Vas deferens (ductus deferens).
B) Urethra.
C) Seminiferous tubule.
D) Rete testis.
Answer: A
Rationale: The vas deferens (ductus deferens) is a thick-walled muscular tube that
transports mature sperm from the epididymis to the ejaculatory duct during
ejaculation.
