1. What is the primary function of the male gonads?
A) Production of seminal fluid
B) Production of sperm and testosterone
C) Storage and maturation of sperm
D) Transport of sperm to the urethra
Correct Answer: Production of sperm and testosterone
Rationale: The male gonads, or testes, are the primary reproductive organs
responsible for producing sperm through spermatogenesis and secreting the
hormone testosterone from the interstitial cells of Leydig. Accessory glands like the
seminal vesicles produce seminal fluid, and the epididymis is responsible for sperm
maturation and storage.
2. Which specific structure within the testes is the site of spermatogenesis?
A) Epididymis
B) Seminiferous tubules
C) Vas deferens
D) Interstitial cells of Leydig
Correct Answer: Seminiferous tubules
,Rationale: Spermatogenesis, the process of sperm production, occurs within the
tightly coiled seminiferous tubules of the testes. The epididymis is where sperm
mature and are stored, and the vas deferens transports sperm. The interstitial cells of
Leydig produce testosterone.
3. What is the primary function of the interstitial cells of Leydig?
A) Producing sperm
B) Secreting inhibin
C) Producing testosterone
D) Secreting seminal fluid
Correct Answer: Producing testosterone
Rationale: The interstitial cells of Leydig, located in the tissue between the
seminiferous tubules of the testes, are responsible for producing and secreting
testosterone. Sperm are produced by the seminiferous tubules, and inhibin is
produced by Sertoli cells.
4. Which structure is responsible for the maturation and storage of sperm?
A) Seminiferous tubules
B) Epididymis
C) Vas deferens
D) Prostate gland
Correct Answer: Epididymis
, Rationale: The epididymis is a coiled tube located on the posterior surface of each
testis where sperm undergo final maturation and are stored until ejaculation. The
seminiferous tubules produce sperm, the vas deferens transports sperm, and the
prostate gland contributes to seminal fluid.
5. What is the correct pathway of sperm from the testes to the urethra?
A) Seminiferous tubules, epididymis, vas deferens, ejaculatory duct, urethra
B) Epididymis, seminiferous tubules, vas deferens, urethra
C) Vas deferens, epididymis, ejaculatory duct, urethra
D) Seminiferous tubules, vas deferens, epididymis, urethra
Correct Answer: Seminiferous tubules, epididymis, vas deferens, ejaculatory duct,
urethra
Rationale: Sperm are produced in the seminiferous tubules, then travel to the
epididymis for maturation and storage. From there, they move into the vas deferens,
then the ejaculatory duct, and finally the urethra during ejaculation. This is the
correct anatomical sequence for sperm transport.
6. Which male accessory gland secretes a fructose-rich fluid that nourishes sperm?
A) Prostate gland
B) Bulbourethral gland
C) Seminal vesicle
D) Epididymis
Correct Answer: Seminal vesicle
