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.
What pituitary hormones control ovulation and production of female hormones by he ovary?
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are the two pituitary hormones that control ovulation and the production of female hormones by the ovaries. LH surge triggers ovulation, while FSH is crucial for the development of ovarian follicles and the production of estrogen.
How are the FSH and LH are released by the hypothalamus?
FSH and LH are released by the hypothalamus in response to gonadotropin-releasing hormone (GnRH) stimulation. GnRH is released in pulses into the bloodstream, which then triggers the release of FSH and LH from the pituitary gland. These hormones play a key role in regulating the reproductive system and stimulating the production of sex hormones in both males and females.
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 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).
What 2 pituitary hormones act on the ovaries and testes?
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are the pituitary hormones that act on the ovaries in females and the testes in males. FSH stimulates egg production in females and sperm production in males, while LH triggers ovulation and testosterone production in females and males, respectively.
What gonadotropin hormones?
FSH and LH are gonadotrophins.They are secreted by pitutory.
What controls the hormones produced by the ovaries and the testes?
Hormones from the hypothalamus and pituitary gland control the hormones produced by the ovaries and testes. The hypothalamus releases gonadotropin-releasing hormone (GnRH), which stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH and LH then act on the ovaries and testes to regulate hormone production.
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.
