Q31. Which of the following hormones stimulates the production of sperm in the testes?
a) Follicle-stimulating hormone (FSH)
b) Luteinizing hormone (LH)
c) Estrogen
d) Progesterone
Show Answer
Correct Answer: a) Follicle-stimulating hormone (FSH)
Explanation: Follicle-stimulating hormone (FSH), released by the anterior pituitary gland, stimulates the Sertoli cells within the seminiferous tubules of the testes to support spermatogenesis—the process of sperm cell formation. FSH acts synergistically with testosterone to regulate spermatogenesis and maintain normal sperm production levels.
Q32. Which of the following structures is responsible for the production and secretion of testosterone?
a) Seminiferous tubules
b) Interstitial cells (Leydig cells)
c) Sertoli cells
d) Prostate gland
Show Answer
Correct Answer: b) Interstitial cells (Leydig cells)
Explanation: Interstitial cells, also known as Leydig cells, are located in the spaces between the seminiferous tubules within the testes. They are responsible for the production and secretion of testosterone in response to luteinizing hormone (LH) released by the anterior pituitary gland. Testosterone plays a crucial role in regulating spermatogenesis and the development of male reproductive tissues and secondary sexual characteristics.
Q33. Which of the following statements about the vas deferens is true?
a) It transports sperm from the testes to the prostate gland.
b) It carries urine from the bladder to the urethra.
c) It is a gland that produces seminal fluid.
d) It is a muscular tube that contracts to propel sperm during ejaculation.
Show Answer
Correct Answer: d) It is a muscular tube that contracts to propel sperm during ejaculation.
Explanation: The vas deferens, also known as the ductus deferens, is a long, muscular tube that carries sperm from the epididymis to the ejaculatory duct during ejaculation. It is lined with smooth muscle tissue that contracts rhythmically to propel sperm forward through peristaltic contractions, aiding in the process of ejaculation.
Q34. Which of the following is a function of the prostate gland in the male reproductive system?
a) Production of sperm
b) Secretion of alkaline fluid to neutralize acidic vaginal environment
c) Storage and maturation of sperm
d) Passage for sperm to enter the urethra
Show Answer
Correct Answer: b) Secretion of alkaline fluid to neutralize acidic vaginal environment
Explanation: The prostate gland is a walnut-sized gland located below the bladder in males. Its primary function is to produce and secrete a milky, alkaline fluid known as prostatic fluid, which makes up a significant portion of semen. Prostatic fluid contains enzymes and nutrients that help nourish and protect sperm, as well as enhance their motility. Additionally, the alkaline nature of prostatic fluid helps neutralize the acidic environment of the female reproductive tract, enhancing sperm survival and motility.
Q35. Which of the following hormones is responsible for stimulating the production of testosterone in the testes?
a) Follicle-stimulating hormone (FSH)
b) Luteinizing hormone (LH)
c) Estrogen
d) Progesterone
Show Answer
Correct Answer: b) Luteinizing hormone (LH)
Explanation: Luteinizing hormone (LH), released by the anterior pituitary gland, stimulates the interstitial cells (Leydig cells) in the testes to produce and release testosterone. Testosterone is the primary male sex hormone responsible for the development and maintenance of male reproductive tissues and secondary sexual characteristics.
Q36. Which part of the male reproductive system carries sperm from the epididymis to the ejaculatory duct?
a) Epididymis
b) Seminal vesicles
c) Vas deferens
d) Bulbourethral gland
Show Answer
Correct Answer: c) Vas deferens
Explanation: The vas deferens, also known as the ductus deferens, is a long, muscular tube that transports sperm from the epididymis to the ejaculatory duct during ejaculation. It serves as a passageway for sperm to travel from the testes to the urethra, where they are expelled during ejaculation.
Q37. What is the primary function of the seminal vesicles in the male reproductive system?
a) Production of sperm
b) Storage and maturation of sperm
c) Secretion of alkaline fluid to neutralize acidic vaginal environment
d) Secretion of seminal fluid
Show Answer
Correct Answer: d) Secretion of seminal fluid
Explanation: The seminal vesicles are a pair of glands located near the base of the bladder in the male reproductive system. Their primary function is to secrete a fluid rich in fructose, enzymes, and prostaglandins, which collectively make up seminal fluid. Seminal fluid provides nutrients and energy to sperm, enhances their motility, and helps neutralize the acidic environment of the female reproductive tract.
