What is the role of follicle-stimulating hormone (FSH) in the menstrual cycle?
- A. To stimulate the release of a mature egg.
- B. To promote the growth and maturation of ovarian follicles.
- C. To thicken the uterine lining for implantation.
- D. To regulate progesterone production post-ovulation.
Correct Answer: B
Rationale: The correct answer is B: To promote the growth and maturation of ovarian follicles. FSH plays a crucial role in the menstrual cycle by stimulating the development of ovarian follicles in the ovary. As FSH levels rise, it triggers the growth of multiple follicles, one of which will eventually mature and release an egg during ovulation. Choice A is incorrect because it is actually luteinizing hormone (LH) that triggers the release of a mature egg. Choice C is incorrect as thickening of the uterine lining is primarily influenced by estrogen and progesterone. Choice D is incorrect because progesterone production is mainly regulated by luteinizing hormone (LH) and not FSH.
