It is secreted by the hypofyse into the bloodstream. Via your blood the hormones arrive at the ovaries.

What gland targets the fsh ans lh?
ovaries
How does FSH stop you from producing eggs?
it tells the ovaries to make oestrogen which then helps mature and egg. the oestrogen then tell the pituitary gland to stop making FSH and make LH. LH then makes the ovaries release eggs =] hope this helped! [=
Does the ovary secrete FSH?
No, the pituitary Gland produces FSH, which is then carried to the Ovaries in your blood stream
How can FSH be the cause of not producing eggs?
FSH, secreted by the Pituitary gland,stimulates the secretion of Oestrogen from the ovaries, Oestrogen in turn stimulates the secretion of LH by the pituitary and inhibits the secretion of FSH, LH then stimulates ovulation (the release of an egg). Without FSH this chain reaction does not happen.
What hormone directly is responsible for regulation of the menstrual cycle?
Estrogens and Progesterone in the ovaries"with a bit of wit"
What does fsh Lh and oestrogen do?
FSH-Follicle-Stimulating Hormone1-secreted by pituitary gland.2-Causes eggs to mature in ovaries.3-Stimulates ovaries to produce oestrogen.Oestrogen1-secreted by ovaries.2-Inhibits (slows down) FSH production.3-Stimulates pituitary gland to produce LH.4-Stimulates uterus lining to build up, ready to support a developing baby.LH-Luteinizing Hormone1-Stimulates ovaries to release eggs.
What gland responsible for menstrual cycle?
estrogen and progesteroneMenstral- LuteinizingUterine- Antidiuretic
Why are fsh and lh given to women juring ivf treatment?
They are used because the FSH stimulates the egg to mature so the doctors are able to take multiple eggs from the ovaries. Oestrogen isn't used in IVF but it is created.
What hormone stimulates activity in the ovaries?
There are many hormones which stimulate activity in the ovaries.The two main ones are FSH (follicle-stimulating hormone) and LH (luteinizing hormone). FSH triggers the growth of an ovum, and LH is involved in causing ovulation (the release of the ovum/egg).
What gland is responsible for initiating menstrual cycle?
Oestrogen & Progesterone are produced by the Ovaries. Follicle Stimulating Hormone (FSH) & Lutenizing Hormone (LH) are produced by the pituitary gland at the base of the brain. FSH and LH control and stimulate the unripe eggs inthe ovaries to ripen and be released. Oestrogen & progesterone stimulate the formation of the endometrium lining in the womb, and by reducing in levels ultimatly casue the breakdown of the lining, and the ensuing period know as menstruation in human females
What causes the peak in luteinizing hormone?
In the beginning of the menstrual cycle, LH and FSH stimulate the ovaries to make estrogen. During this time, there is a negative feedback loop, so levels of all three hormones are rather low. Eventually, as the estrogen levels slowly creep up, there comes a time when it switches from negative feedback to positive feedback (not exactly sure what the biochemical basis of this is), and LH and FSH levels skyrocket (estrogen levels go up to, but not as sharply, and there is always more LH than FSH). The LH surge causes ovulaton. The corpus luteum starts secreting progesterone, which inhibits LH and FSH secretion in a negative feedback manner, and so FSH and LH levels drop sharply.
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.
