Gonadotropin-releasing hormone (gnrh) stimulates what?

Gonadotropin-releasing hormone (gnrh) stimulates what?

FSH,LH: Gnrh stimulates follicle stimulating hormone & luteinizing hormone which stimulates the ovary to produce estrogen and Progesterone which stimulates ovulation which causes increased Progesterone which causes secretory endometrium which prepares the endometrium to allow implantation of a fertilized egg. If no fertilized egg, Progesterone falls which stimulates gnrh to again rise & the cycle repeats. ...Read more

Gonadotropin-releasing hormone (gnrh) stimulates the production what?

Good question: Gnrh would seem by its name to help release gonadotropin. And if used in a certain fashion it could cause the release of gonadotropins (lh, fsh). However when given in a shot and having a sustained effect on the pituitary, it actually suppresses the release of lh and fsh. And this aspect of the medication can be used to help in many situations. ...Read more

Any doctor prescribe gnrh in ny? Can someone help me to locate a obgyn in ny who prescribe gnrh in ny?

Any doctor prescribe gnrh in ny? Can someone help me to locate a obgyn in ny who prescribe gnrh in ny?

See the right kind: Any doctor can prescribe gnrh but you need to see the right type of doctor to be sure you are being treated appropriately. Pure gnrh is used to help women ovulate who have a very specific hormone imbalance. Very few people in the field of reproductive medicine still use this. If you are interested in a gnrh agonist such as Lupron (leuprolide) most gyns use it commonly. ...Read more

What releases anterior pituitary gonadotropins?

Gonadotropes: Fsh and lh are pituitary gonadotropins, they are released in response to pulsatile signals of gnrh from the hypothalamus. The cells that store and release them are sometimes called gonadotropes. ...Read more

Do you control parathyroid hormone secretion using casr antagonist?

Do you control parathyroid hormone secretion using casr antagonist?

Her how it works: The g protein-coupled, seven-pass transmembrane molecule present in the parathyroid gland and kidney controls calcium homeostasis by releasing parathyroid hormone (pth). Manipulating calcium-sensing receptor (casr) using small-molecule allosteric modulators can affect PTH secretion. ...Read more

How can electrical bone growth stimulator help with spine fusion?

How can electrical bone growth stimulator help with spine fusion?

Perhaps: The basic science shows effectiveness, but its use in people has produced conflicting results. It may be useful if you are at risk for not healing a fusion. Some risk factors include tobacco use, prior failed attempts at fusion in the same area of your back, multiple level fusion. Talk to your doctor. Check to see if your insurance covers it. ...Read more

What are nerve stimulator implants side effects?

What are nerve stimulator implants side effects?

Risk vs benefits: Infection is the #1 risk which is less than 4% per 2004 study in journal neurosurgery spine. Less common risks include bleeding, nerve irritation/damage, allergic reaction, hardware malfunction, pain at implant site, dysesthesias, and spinal headache. The risks are fairly low in the hands of an experienced physician, and the benefits can be great. Talk to your doc about details. ...Read more

Can a zoladex (goserelin) 3.6mg implant induce artificial menopause?

Chemical menopause: Zoladex (goserelin) 3.6 mg implanted every 28 days will put a woman chemically into menopause and make her menstrual periods stop. In fact, about 2 weeks after the first implant there will be a hormone withdrawal bleeding, after the next implant there will be no bleeding, if the medication works perfectly. ...Read more

What is gnrh hormone?

Complicated: Gnrh stands for gonadotropin releasing hornone. It's a neurohormone produced in the hypothalamus (part of the brain). Its release controls the production/release of 2 pituitary hormones called luteinizing hormone (lh) and follicle stimulating hormone (fsh) which in turn regulate and affect your ovary/menstrual periods or in men sperm and testosterone production. ...Read more

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

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

Why is gnrh released in pulses rather than a continual steady stream?

Different effects: Continuous secretion of gnrh suppresses production of FSH & lh from the pituitary. Pulses of gnrh stimulate production of FSH & lh from the pituitary. ...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

Can an increase in testosterone decrease gnrh release?

Yes: Testosterone (from the testicles) and gnrh (from the hypothalamus) are connected by a feedback mechanism much like the thermostat in one's house. When testosterone levels rise for whatever reason, the hypothalamus decreases its release of gnrh to help bring t back to normal levels and vice versa. ...Read more

Why do patients taking gnrh-a lose bone?

GnRH hormones: While normally gnrh stimulates sex hormones, it achieves this only when it is secreted in bursts by the hypothalamus. When given in injections, it circulates continuously and it suppresses the hormones that in turn stimulate the ovary in women and the testes in men. As a consequence, there is a lack of sex hormones (estradiol in women, testosterone in men, leading to bone loss as in menopause. ...Read more

I was told that I had a slight decrease in my bone density while on gnrh-a. Can you explain this?

Low estrogen: Estrogen is important for building bone and maintaining bone density. When one is on gnrha therapy (lupron) estrogen concentrations are low, and therefore bone is lost. Fortunately, after stopping therapy, bone density tends to return to normal. ...Read more

Why do FSH levels rise around day 14 of the cycle? Is it just because of the higher GnRH that cause the LH surge?

Why do FSH levels rise around day 14 of the cycle?  Is it just because of the higher GnRH that cause the LH surge?

You asked...: FSH rises because 1) it induces expression of its own receptor and 2) it stimulates E2 production, which also induces expression of more FSH receptors. GnRH is not "higher" or lower, GnRH is pulsatile: the frequency of the pulses is as important (or more) than the pulse amplitude. If this unclear, I suggest consulting an endocrinology text, there is no short version. ...Read more

Is it true that gnrh agonists are good treatments for endometriosis?

Is it true that gnrh agonists are good treatments for endometriosis?

Temporary Relief?: First, one needs to be sure of the diagnosis. It is a surgical diagnosis. Second, these medications create a temporary menopause with numerous side effects including bone loss. Add back hormones may help. That stated, these medications allow for the shrinking of the lesions but they are not removed. Within three months of stopping the medication, the lesions are back with symptoms to follow. ...Read more
