Which hormone is secreted by the anterior pituitary and stimulates the ovaries?

The hormone secreted by the anterior pituitary that stimulates the ovaries is Follicle Stimulating Hormone (FSH). FSH plays a crucial role in the regulation of the menstrual cycle and the development of ovarian follicles in females. Specifically, it promotes the growth and maturation of ovarian follicles, which are necessary for ovulation and the production of estrogen.

In this context, FSH is essential for reproductive health as it helps in the formation of eggs and the regulation of menstrual cycles. It also works in conjunction with Luteinizing Hormone (LH), another hormone produced by the anterior pituitary, to ensure proper functioning of the reproductive system.

Other hormones listed do not have the same effect on the ovaries. For instance, Thyroid Stimulating Hormone primarily affects the thyroid gland and regulates thyroid hormone production. Adrenocorticotropic Hormone stimulates the adrenal cortex and is involved in cortisol production, while Growth Hormone is important for growth and metabolism but does not have a direct role in ovarian stimulation. Thus, FSH is distinctly recognized for its critical function in stimulating the ovaries.
