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.

What hormones does pituitary produce?
FSH and LH.
FSH and LH are two hormones produced by the?
Pituitary Gland
What are the two hormones FSH and LH produced by?
FSH (Follicle stimulating hormone) and LH (Lutenizing hormone) are produced by the pituitary gland in the brain. Specifically, the anterior region of the pituitary gland.
Which glands and hormones are affected by Oophorectomy?
The Pituitary Gland Hormones: Lutenizing Hormone (LH) and Follicle Stimulating Hormone (FSH), which stimulates the production of estrogen and progesterone
What are three endocrine organs whose activity is stimulated by pituitary hormones?
The adrenals, thyroid, and gonads are affevcted by hormones from the anterior pituitary. These hormones are ACTH, TSH, FSH, and LH.
What is gonaclotropin?
Its gonadotropin. These are the hormones produced by the pituitary gland in the brain and in placenta which regulates the sexual system. It includes FSH, LH and hCG.
Which two hormones controlling the menstrual cycle are produced in the pituitary gland?
The two hormones are LH and FSH. Both are necessary for proper function of the ovary. Together they produce a mature egg. After the egg is released and not fertilized, menstruation will occur. Menstruation occurs when the lining of the uterus is "lost" since it doesn't need to be ready to accept a zygote (fertilized egg).
Where are LH and FSH produced?
Gonadotropic hormones FSH (Follicle stimulating hormone) and LH (Luteinizing hormone) are produced and secreted by the gonadotrophs in anterior pituitary. These are the trophic hormones that act on the ovaries and testes. Required for ovulation, spermatogenesis, biosynthesis of estrogens and androgens. They are also used therapeutically to promote fertility. Their secretion is regulated by the hypothalamus GRH (gonadotropin releasing hormone), where GRH stimulates the release of FSH and LH and FSH and LH feedback and decreases levels of GRH release. Estrogens and androgens also feedback and inhibit the gonadotrophs in the pituitary and feedback on the hypothalamus.
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.
A tropic hormone is any hormone that?
Hormones that target other endocrine glands. Produced by anterior pituitary. Include: FSH, TSH, LH, ACTH.
What gland produces Fsh and LH?
The pituatry gland.
The part of the brain where both LH and FSH are made?
the pituitary gland
