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.

- C. Reduced rate of secretion of progesterone from the corpus luteum

Choice C is incorrect as progesterone is mainly produced by the corpus luteum after ovulation, not the primary cause of menopause.
