A major function of FSH is to
- A. stimulate the development of the gonads during early development.
- B. stimulate spermatogenesis in males and oocytes maturation in females.
- C. increase the secretion of testosterone by the testes.
- D. regulate the secretion of the bulbourethral gland
Correct Answer: B
Rationale: The correct answer is B because FSH, or Follicle-Stimulating Hormone, stimulates spermatogenesis in males and oocyte maturation in females. In males, FSH acts on the Sertoli cells in the testes to promote the development of sperm cells. In females, FSH stimulates the growth and maturation of ovarian follicles, leading to the release of mature eggs.
Choice A is incorrect because FSH is not primarily responsible for the development of gonads during early development. Choice C is incorrect because FSH does not directly increase the secretion of testosterone by the testes; that is the role of LH (Luteinizing Hormone). Choice D is incorrect because FSH does not regulate the secretion of the bulbourethral gland; that is controlled by other hormones.

A mature ovarian follicle that is ready to be ejected from an ovary is called a(n) ________.
- A. primary oocyte
- B. vesicular (Graafian) follicle
- C. ovum
- D. corpus luteum
Correct Answer: B
Rationale: The correct answer is B: vesicular (Graafian) follicle. A mature ovarian follicle ready for ovulation is called a vesicular follicle. It is the final stage before ovulation. A: primary oocyte is incorrect as it refers to an immature egg cell. C: ovum is incorrect as it refers to a mature egg cell after fertilization. D: corpus luteum is incorrect as it forms after ovulation and is responsible for producing progesterone, not the mature follicle.
Which of these is not a function of testosterone?
- A. loss of body hair
- B. thickening of the larynx
- C. anabolism of skeletal muscle
- D. thickening of bones
Correct Answer: A
Rationale: The correct answer is A, loss of body hair. Testosterone is responsible for thickening of the larynx, anabolism of skeletal muscle, and thickening of bones. It promotes growth and development of male secondary sexual characteristics, such as increased body hair. Therefore, loss of body hair is not a function of testosterone. Choice B, thickening of the larynx, is correct because testosterone contributes to the deepening of the voice by thickening the vocal cords. Choice C, anabolism of skeletal muscle, is correct as testosterone enhances protein synthesis in muscles, leading to muscle growth. Choice D, thickening of bones, is correct because testosterone promotes bone growth and mineralization.
Her Hemovac has drained 60 ml postoperative day 1, 55 ml postoperative day 2, and 40 ml thus far today. She asks you when will the drain be removed. Which would be the most appropriate response?

Primary spermatogonium undergo:
- A. two mitotic divisions to become a secondary spermatocyte
- B. mitosis and then meiosis to become a secondary spermatocyte
- C. two meiotic divisions to become a secondary spermatocyte
- D. meiosis and differentiation to become a secondary spermatocyte
Correct Answer: B
Rationale: The correct answer is B. Primary spermatogonium undergo mitosis to replicate and maintain the diploid chromosome number, then meiosis to reduce the chromosome number, resulting in secondary spermatocytes. Choice A is incorrect as it skips meiosis. Choice C is incorrect as it suggests two meiotic divisions from primary spermatogonium, which is not accurate. Choice D is incorrect because it fails to mention the initial step of mitosis before meiosis in the process.
