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.

What inhibits the release of FSH from the anterior pituitary and GnRH from the hypothalamus when the sperm count is high?
Inhibin
What secretes and produces GnRH?
Hypothalamus
Does the anterior pituitary gland produce hormones?
The anterior pituitary gland in the brain is the first place the Gaonadotrophin Releasing Hormone (GnRH) goes when it is produced by the Hypothalamus (a region in the brain). Next, two hormones are produced, the Follicle Stimulating Hormone (FSH) and the Lutenizing Hormone (LH). Basically, the Hypothalamus is the starting place. GnRH is produce there and then goes to the anterior pituitary gland. Because of this, FSH and LH are produced. This process is the progression from pre-puberty to puberty.
What neurons of the supraoptic nuclei of the hypothalamus manufacture?
CRF and GnRH
What is the follicle stimulating hormone?
It is secreted by pitutory.Stimulated by GnRH secreted by Hypothalamus.
What inhibits the release of FSH from the anterior pituitary and GnRH from the hypothalamus when the sperm count is high?
Inhibin
Where is Gnrh produced?
what i learned in class was that GnRH was produced by the Hypothalamus gland, and it stimulated the release of FSH and LH in the Anterior lobe of the pituitary gland.
What organ secretes follicle stimulating hormone?
Follicle-stimulating hormone (FSH) is a glycoprotein gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH), which is released by the hypothalamus.
Where is FSH secreted?
Both are produced in the anterior pituitary.
Is GnRH's target organ the pituitary gland?
The answer is Anterior Pituitary
What gland is LH found in?
LH or Luteinizing Hormone is released from the anterior pituitary gland which is stimulated by GnRH or Gonadotropin-releasing hormone in the hypothalamus.
What secretes and produces GnRH?
Hypothalamus
What hormone initiates menarche?
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

What hormone controls the release of anterior pititary gondotropins?
Follicle-Stimulating Hormone (FSH)The anterior pituitary gland is controlled via portal system of veins from the Hypothalamus. Directly the Hypothalamus secretes GnRH (gonadtropin releasing hormone) to the anterior pituitary gland to stimulate the release of the gonadtropins FSH (follicle stimulating hormone) and LH (lutenizing hormone). Testosterone is a male sex hormone that is synthesized by cells stimulated by LH & FSH
What is the function of GnRH?
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).
What hormone secreted by the hypothalamus stimulates the anterior pituitary to secrete reproductive hormones?
Gonadotropin-releasing hormone(GnRH) is secreted by the hypothalamus to stimulate the anterior pituitary which in turn secretes reproductive hormones.(LH and FSH). These last two act differently in males and females. In females, LH, is involved in the menstrual cycle and the production of progesterone. In males, LH helps in the production of testosterone. In Females FSH, helps in the production of estrogen. In males FSH, is important in the maturation of sperm.
