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.
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! [=
What are the male sex hormone?
Testosterone, oestrogen, Fsh, LH,prolactinThere are two primary ones: Testosterone, and androgen.
Which hormones exerts its effect primarily on the reproductive organs?
(FSH) Follicle-stimulating hormone. (LH) Luteinising hormone. Oestrogen. Testosterone.
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.
How are FSH and LH involved in reproduction?
the follicle stimulation hormone is produced by the putuitary gland which stimulates the hormone oestrogen to releases eggs. the lh causes the released eggs to go to the follopian tube
What are the chemical messengers that control changes during the menstrual cycle?
They are Oestrogen, Progesterone, LH-leutinising hormone and FSH-follicle stimulating hormone. A fifth hormone that also is important is Prolactin.
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
How does oestrogen affect FSH?
Oestrogen is produced by the ovaries and inhibits(stops) the further production of FSH.
What regulates estrogen and progesterone?
LH ( luteinising hormone) is stimulated by oestrogen and secreted by the pituitary gland. As oestrogen levels rise it will inhibit the production of FSH (follicle stimulating hormone) and will encourage the production of LH. As LH rises to a peak in the middle of the menstrual cycle, they will stimulate the release of a mature egg.
What effects does oestrogen have on the production of fsh?
Estrogen induces a biphasic feedback on the gonadotropin releasing. In the first phase (it is discussed whether the phases are separated by time or by estrogen levels) it induces an negative feedback on both FSH and LH. The inhibition of FSH is more evident in this case. In the second phase the feedback is positive. In contrary the positive feedback is much more evident in the LH level.
What hormones does pituitary produce?
FSH and LH.
