Only a little amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from ...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

Is there something like a melatonin releasing hormone, kind of like some of the other pituitary hormones have?

Is there something like a melatonin releasing hormone, kind of like some of the other pituitary hormones have?

None discovered yet: Melatonin is secreted by the pineal gland in response to light/dark cycles and other stimuli. It doesn't change much when persons are placed in dark rooms for several days. Also nocturnal mammals like rats have the same secretion schedule as animals active in daytime. High dose melatonin can actually influence pituitary secretion of prolactin.

Could you please describe how hormone structure determines its function?

Could you please describe how hormone structure determines its function?

Hormone-Receptor: Hi. All hormones work by binding very specifically with high affinity to their cognate receptor. This is often describe as lock & key; only one specific key will open a lock. The receptor has a binding pocket for the hormone, and the hormone's structure is what makes it have binding specificity for its receptor. Hormone binding to its receptor sends a signal to cell to regulate some function. ...Read more

Could I get some information on natural hormone replacement?

Could I get some information on natural hormone replacement?

See below: Could I get some information on natural hormone replacement? Natural hormone therapy consists of replacing hormone deficiencies within your body with bio identical hormones. This implies that the hormones your taking into your body have a very similar chemical structure to the hormones that are already present in your body. Bioidentical hormones are traditionally given in a cream base and absorbed through the skin. Depending on what base they're put into most are absorbed in somewhere between 15 and 45 seconds. The advantage of absorbing through the skin is that they don't have to pass through the liver at which time some of the compound will be broken down and not be able to be utilized by the body. Unlike traditional hormone replacement therapy, which has been associated with a multiplicity of problems, that is not the case for natural hormone therapy. See the women's health initiative study for additional information on traditional hormone replacement therapy. We have been using natural hormone therapy consistently in our office for the past 18 years with very impressive results. We use a questionnaire and saliva testing to first identify the status of the patient's hormone balance. Once we've identified the patient's hormonal status we use bio identical hormones to get the well-deserved balance. Many of the symptoms that women often take as normal such as menstrual cramping, heavy menstruation, irritability during the time of their menstruation, hot flashes and night sweats are not normal and can be significantly improved upon with natural hormone therapy.

Are human growth hormone supplements bad if not abused. Just in moderation even for sports or gym purposes?

Why bother?: They're pricey, they're cheating, and they offer little benefit unless you want to end up grotesquely muscled. Whoever's trying to sell you this is probably claiming benefits that it cannot deliver. Why not be able to tell everyone, truthfully, "This is entirely natural." ...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
