Questions and Answers
- 1.
Acts as a natural climate control center for the testicles in order to maintain viability of sperm
- A.
Prostate glands
- B.
Testes
- C.
Scrotum
- D.
Penis
Correct Answer
C. ScrotumExplanation
The scrotum is the correct answer because it acts as a natural climate control center for the testicles. The testicles need a slightly lower temperature than the rest of the body in order to maintain the viability of sperm. The scrotum helps regulate this temperature by contracting or relaxing the muscles, bringing the testicles closer to or further away from the body to adjust the temperature as needed.Rate this question:

Acts as male organ of copulation (sex) and urination
- A.
Penis
- B.
Scrotum
- C.
Testicle
- D.
Epididymis
Correct Answer
A. PenisExplanation
The penis is the correct answer because it serves as the male organ of copulation (sex) and urination. It is responsible for delivering sperm during sexual intercourse and for expelling urine from the body. The scrotum, testicles, and epididymis are also involved in the male reproductive system, but they do not directly perform the functions mentioned in the question.Rate this question:

Provides the male sex hormone testosterone also the site of sperm development and formation
- A.
Prostate gland
- B.
Scrotum
- C.
Testes
- D.
Penis
Correct Answer
C. TestesExplanation
The testes are responsible for producing the male sex hormone testosterone and also serve as the site for sperm development and formation. They are located in the scrotum, which is a sac-like structure outside the body that helps regulate the temperature of the testes for optimal sperm production. The prostate gland, on the other hand, is a part of the male reproductive system that produces seminal fluid, while the penis is the male organ used for sexual intercourse and urination.Rate this question:

Acts as a site for the maturation of sperm
- A.
Scrotum
- B.
Penis
- C.
Testes
- D.
Epididymis
Correct Answer
D. EpididymisExplanation
The epididymis is a coiled tube located on the back of each testicle. It acts as a site for the maturation of sperm, where they gain the ability to swim and fertilize an egg. Sperm are stored in the epididymis until they are ready to be ejaculated during sexual intercourse. Therefore, the epididymis plays a crucial role in the reproductive system by facilitating the development and storage of mature sperm.Rate this question:

Produces a slightly alkaline fluid that becomes a part of the seminal fluid or semen
- A.
Prostate gland
- B.
Vas deferens
- C.
Seminal vesicles
- D.
Testes
Correct Answer
C. Seminal vesiclesExplanation
The seminal vesicles produce a slightly alkaline fluid that becomes a part of the seminal fluid or semen. This fluid helps to nourish and protect sperm as they travel through the reproductive system. It also helps to neutralize the acidity of the vagina, creating a more favorable environment for sperm survival and fertilization.Rate this question:

Secretes an alkaline fluid that aids in maintaining the viability of spermatozoa
- A.
Testes
- B.
Prostate gland
- C.
Scrotum
- D.
Urethra
Correct Answer
B. Prostate glandExplanation
The prostate gland secretes an alkaline fluid that helps in maintaining the viability of spermatozoa. This fluid is a component of semen and helps to neutralize the acidic environment of the vagina, providing a more favorable environment for the sperm to survive and fertilize an egg. The prostate gland is located below the bladder and surrounds the urethra, which allows the alkaline fluid to mix with sperm during ejaculation. The testes produce sperm, the scrotum houses the testes, and the urethra is the tube through which urine and semen pass.Rate this question:

Produces a mucous secretion before ejaculation which becomes a part of semen
- A.
Scrotum
- B.
Prostate glands
- C.
Bulbourethral or cowper's glands
- D.
Vas deferens
Correct Answer
C. Bulbourethral or cowper's glandsExplanation
The bulbourethral or Cowper's glands are responsible for producing a mucous secretion before ejaculation, which then becomes a part of semen. This secretion helps to lubricate the urethra and neutralize any acidity in the urethra, providing a more favorable environment for sperm survival and motility.Rate this question:

Transmits urine and semen out of the body
- A.
Urethra
- B.
Testes
- C.
Penis
- D.
Scrotum
Correct Answer
A. UrethraExplanation
The urethra is a tube that serves as a passage for both urine and semen to exit the body. It connects the bladder to the external opening of the body, allowing the elimination of urine during urination and the ejaculation of semen during sexual intercourse. The testes are responsible for producing sperm, while the penis is the male organ involved in sexual intercourse. The scrotum is a sac that holds the testes and helps regulate their temperature. However, only the urethra is directly involved in the transmission of both urine and semen.Rate this question:
