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.

How does GnRH get from the hypothalamus to the anterior pituitary and what effects does it have on the pituitary?
GnRH travels through the hypophyseal portal system from the hypothalamus to the anterior pituitary gland. Once it reaches the pituitary, GnRH stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. FSH and LH play crucial roles in regulating the reproductive system, such as promoting the growth and maturation of ovarian follicles in females and sperm production in males.
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.
Which two hormones controlling the menstrual cycle are produced in the pituitary gland?
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are the two hormones produced in the pituitary gland that play a key role in controlling the menstrual cycle. FSH stimulates the growth of ovarian follicles, while LH triggers ovulation and helps regulate the production of estrogen and progesterone.
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 is GnRH produced by?
GnRH, or gonadotropin-releasing hormone, is produced by the hypothalamus in the brain. It plays a crucial role in the regulation of reproductive functions by stimulating the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland.
Gonadotropin stimulating hormone is released by the and affects the?
gonadotropin releasing hormone is released by the hypothalamus during the menstrual cycle. it then stimulates the pituitary gland to release LH and FSH
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 controls the release of anterior pititary gondotropins?
Gonadotropin-releasing hormone (GnRH) controls the release of anterior pituitary gonadotropins, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH). GnRH is released from the hypothalamus in a pulsatile manner to regulate the production and secretion of these hormones.
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.
Which hormone requires a releasing hormone from the hypothalamus for its secretion?
All the hormones from posterior Pitutory.They are FSH,LH,TSH,GH,Prolactin and AcTH.
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 allows Follicle-stimulating hormone and Luteinizing hormone levels to increase again?
Once GnRH levels increase, FSH and LH levels will increase. During pregnancy, GnRH is not required which is responsible for the lack or absence of FSH and LH production. Prolactin can also decrease GnRH production which again will decrease FSH and LH. Luteinizing hormone (LH) levels can also be affected by another hormone called melatonin, which is regulated by the hypothalamus and released by the pineal gland in repsonse to the amount of broad-spectrum light that enters the eyes.
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).
How do fsh n lh help in pcos?
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.

What hormones does pituitary produce?
FSH and LH.
What inhibits secretion of LH and FSH?
Progesterone
