What hormone promotes the development of ovarian follicles?

• A. Luteinizing hormone (LH)
• B. Prolactin
• C. Follicle-stimulating hormone (FSH)
• D. Estradiol

Answer: (C)

Follicle-stimulating hormone (FSH) is the hormone specifically responsible for promoting the development of ovarian follicles. During the follicular phase of the menstrual cycle, FSH stimulates the ovaries to allow the growth and maturation of ovarian follicles, which are essential for ovulation and fertility. Each follicle contains an oocyte, and as FSH levels increase, it encourages these follicles to grow, facilitate hormone production, and ultimately prepare for the possibility of fertilization.

The role of FSH is crucial in the menstrual cycle, as it not only initiates follicular growth but also influences the secretion of estradiol from the developing follicles, which in turn plays various roles in regulating the reproductive cycle. FSH works synergistically with luteinizing hormone (LH), but it is specifically FSH that primarily drives the maturation of follicles in the ovaries.

Understanding the function of FSH is vital for grasping the broader dynamics of reproductive endocrinology and how various hormones interact during the menstrual cycle.
