What role does follicle-stimulating hormone (FSH) play in female reproduction?

Follicle-stimulating hormone (FSH) is crucial for female reproduction as it primarily stimulates the growth and maturation of ovarian follicles. During the follicular phase of the menstrual cycle, FSH is released from the pituitary gland and signals the ovaries to promote the growth of several follicles, each of which contains an egg. This process leads to one dominant follicle maturing fully, which is essential for successful ovulation.

The significance of FSH is highlighted by its role in the development of these follicles, which produce estrogen and prepare the body for potential fertilization. Without adequate levels of FSH, the follicles may not develop properly, leading to issues such as irregular menstruation or infertility.

While menstruation and ovulation are critical aspects of female reproductive health, FSH does not directly regulate menstrual flow or prevent ovulation. Instead, it plays a supportive role in preparing the body for ovulation by ensuring that the follicles are ready to release an egg. Thus, stimulating the growth of ovarian follicles is the accurate portrayal of FSH's primary function in female reproduction.
