Which hormone stimulates the growth of ovarian follicles in the ovary?

Follicle-stimulating hormone (FSH) plays a crucial role in the reproductive system, specifically in the development of ovarian follicles. This hormone, secreted by the pituitary gland, directly stimulates the growth and maturation of the ovarian follicles, which are fluid-filled sacs that contain and nurture developing eggs. FSH is essential for the early stages of follicular development and works in conjunction with other hormones to facilitate proper ovary function and menstrual cycle regulation.

When FSH levels rise, it encourages the growth of several ovarian follicles, leading to the production of estrogen as these follicles mature. This process is vital for female fertility and overall reproductive health, as the follicles are responsible for producing the eggs necessary for reproduction. The interplay between FSH and the developing follicles sets the stage for ovulation and potential conception.
