Hormones control the human body’s reproductive system. The two hormones secreted by the pituitary glands are follicle-stimulating hormone (FSH) and luteinizing hormone (LH), both of which are secreted in response to the release of GnRH from the hypothalamus. FSH travels to the ovaries and stimulates a group of follicles to grow. These primordial follicles develop into primary follicles and then secondary follicles.
Follicle stimulating hormone (FSH) is one of the gonadotrophic hormones. FSH is one of the hormones essential to pubertal development and the function of women’s ovaries and men’s testes. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation.[1]
Luteinizing hormone (LH) is produced and released in the anterior pituitary gland. It controls the function of ovaries in females. Two weeks into a woman’s cycle, a surge in luteinizing hormone causes the ovaries to release an egg during ovulation. If fertilization occurs, luteinizing hormone will stimulate the corpus luteum, which produces progesterone to sustain the pregnancy.[3]
