FSH and LH
It is produced by Hypothalamus.It stimulates production FSH and LH.
FSH-Follicle stimulating hormone
In both male and female,GnRH produced and released by Hypothalamus.It stimulates Anterior Pitutory to release FSH and LH
The hypophysial portal system carries gonadotropin-releasing hormone (GnRH) from the hypothalamus to the anterior pituitary. It stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.
GnRH, short for gonadotropin-releasing hormone, is released by the part of the brain known as the hypothalamus. At the beginning of the menstual cycle, the hypothalamus releases GnRH. The GnRH then stimulates a different part of the brain, the pituitary gland, to produce two hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
inhibiting the secretion of GnRH
During the Luteal phase of the menstrual cycle there is a decrease in the levels of Estrogen (Estradiol) and Progesterone which causes stimulation of Gonadotropin releasing hormone (GnRH). Gonadotropin releasing hormone (GnRH) stimulates the anterior pituitary to secrete Follicle-stimulating Hormone (FSH).
GnRH from the hypothalamus stimulates RH and FSH from the anterior pituitary gland. These start menarche, and are assisted during the menstrual cycle by oestrogen and progesterone
The release of Follicle-stimulating hormone(FSH) and Luteinizing hormone(LH) stimulates cells in the testes to produce Testosterone.
GnRH-gonadotropin realeasing hormone
The onset of puberty is triggered by the release of GnRH from the hypothalamus.
