GnRH stands for Gonadotropin-Releasing Hormone. It is a hormone produced in the hypothalamus that stimulates the release of other hormones involved in reproduction, such as LH and FSH.
GnRH, LH, FSH, inhibin, testosterone (in males), estrogens and progesterone (in females).
In PCOS patient there is Elevated level of LH where dr cannot use HMG, coz HMG has FSH and LH in 1:1 ratio. AS LH levels r high in PCOS patient no need to give LH. so in those patient Dr's can use on FSH for follicular growth.

There are many hormones which stimulate activity in the ovaries.The two main ones are FSH (follicle-stimulating hormone) and LH (luteinizing hormone). FSH triggers the growth of an ovum, and LH is involved in causing ovulation (the release of the ovum/egg).
Follicle-stimulating hormone (FSH) is a hormone synthesised and secreted by gonadotropes in the anterior pituitary gland. FSH and LH act synergistically in reproduction: * In women, in the ovary FSH stimulates the growth of immature Graafian follicles to maturation. As the follicle grows, it releases inhibin, which shuts off the FSH production. * In men, FSH enhances the production of androgen-binding protein by the Sertoli cells of the testes, and is critical for spermatogenesis. Luteinizing hormone (LH, also known as lutropin) is a hormone synthesized and secreted by gonadotropes in the anterior lobe of the pituitary gland. In concert with the other pituitary gonadotropin follicle stimulating hormone (FSH) it is necessary for proper reproductive function: * In the female, an acute rise of LH - the LH surge - triggers ovulation. * In the male, where LH had also been called Interstitial Cell Stimulating Hormone (ICSH), it stimulates Leydig cell production of testosterone.

FSH and LH are gonadotrophins.They are secreted by pitutory.
