What is the primary function of the epididymis in the male reproductive system?
A.
Production of testosterone
B.
Storage and maturation of sperm
C.
Transport of sperm
D.
Secretion of seminal fluid
Show Answer & Explanation
Correct Answer: B
The epididymis is a coiled tube that stores sperm and allows them to mature. It plays a crucial role in the development of sperm motility.
Q3
Easy
Which hormone is primarily responsible for the regulation of spermatogenesis in males?
A.
Estrogen
B.
Progesterone
C.
Luteinizing hormone (LH)
D.
Follicle-stimulating hormone (FSH)
Show Answer & Explanation
Correct Answer: D
Follicle-stimulating hormone (FSH) stimulates the Sertoli cells in the seminiferous tubules to facilitate sperm maturation and production.
Q4
Medium
What is the primary function of the testes in the male reproductive system?
A.
Production of sperm
B.
Secretion of testosterone
C.
Storage of sperm
D.
Regulation of body temperature
Show Answer & Explanation
Correct Answer: A
The primary function of the testes is to produce sperm, while they also secrete testosterone, but sperm production is their main role.
Q5
Medium
Which structure is responsible for the maturation of sperm?
A.
Seminal vesicle
B.
Epididymis
C.
Vas deferens
D.
Prostate gland
Show Answer & Explanation
Correct Answer: B
The epididymis is where sperm mature and gain motility before they are ejaculated.
Q6
Medium
At what temperature do the testes need to be maintained for optimal sperm production?
A.
37°C
B.
35°C
C.
33°C
D.
31°C
Show Answer & Explanation

The optimal temperature for sperm production is slightly below the normal body temperature, around 35°C.
Q7
Medium
Which hormone is mainly responsible for the development of male secondary sexual characteristics?
A.
Estrogen
B.
Progesterone
C.
Testosterone
D.
Luteinizing hormone
Show Answer & Explanation
Correct Answer: C
Testosterone is the hormone that drives the development of male secondary sexual characteristics such as facial hair and deep voice.
Q8
Hard
Which hormone is primarily responsible for the development of secondary male sexual characteristics?
A.
Testosterone
B.
Estrogen
C.
Progesterone
D.
Luteinizing hormone
Show Answer & Explanation
Correct Answer: A
Testosterone promotes the development of secondary sexual characteristics such as increased muscle mass, deeper voice, and facial hair.
Q9
Hard
What is the primary function of the seminal vesicles?
A.
Produce sperm
B.
Produce testosterone
C.
Secrete seminal fluid
D.
Store sperm
Show Answer & Explanation
Correct Answer: C
Seminal vesicles secrete a significant portion of the seminal fluid that nourishes and helps transport sperm.
Q10
Hard
Which of the following structures is responsible for the maturation of sperm?
A.
Sertoli cells
B.
Leydig cells
C.
Epididymis
D.
Seminal vesicles
Show Answer & Explanation
Correct Answer: C
The epididymis is the site where sperm mature and gain motility after they leave the testes.
