More Info
The gonadotropin-releasing hormone (GnRH) plays a key role in regulating estrogen levels, along with the levels of other reproductive hormones. GnRH is produced by the brain and binds to receptors on the pituitary gland. This stimulates the production of two hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH), which control the levels of reproductive hormones such as estrogen and progesterone. Among other roles in the body, estrogen and progesterone are essential to stimulating the growth and break down of the endometrium
