What hormones stimulate the release of gnrh?

What hormones stimulate the release of gnrh?

Insulin: GnRH is stimulated by an increase in insulin (as can be seen in PCOS). An increase in prolactin causes a decrease in GnRH. GnRH is low in early childhood, then is activated in puberty, and has a pulsatile release for normal reproductive function. What exactly initiates puberty is not completely known with biological and environmental factors playing a role. ...Read more

Why we don't use b2 agonist for angina pectoris?

Why we don't use b2 agonist for angina pectoris?

Can you tell me about hormones: gnrh surge--> lh?

Can you tell me about hormones: gnrh surge--> lh?

Normal: I am not sure what you are asking, but GNRH is a hormone produced by the hypothalamus. It is made in a pulsatile manner normally. This acts on the pituitary gland to cause the release of LH, also in a pulsatile manner. Taking large amounts of GNRH analogs (such as Lupron) initially causes release of LH, but then suppresses further release (thereby turning off testosterone or estrogen production) ...Read more

Can you tell me for some women, secretion of gnrh is inadequate, they're consider sterile and are treated drugs that mimic it?

Can you tell me for some women, secretion of gnrh is inadequate, they're consider sterile and are treated drugs that mimic it?

GnRH secretion: Some women (and men) fail to secrete GnRH from the hypothalamus (part of the brain). Therefore, there is no signal to the pituitary to make reproductive hormones (FSH and LH). In Europe, Factrel is available via an automated pump. In the US, we give fertility pts FSH and hCG to cause ovulation. For those women not trying to conceive, estrogen and progesterone hormone replacement is given. ...Read more
