Testosterone is produced in the testes (gonads, balls, testicles) from progesterone and other precursors (androgen, DHEA, etc.) which are all products of cholesterol. (See diagram below). For this reason they are all called "sterols". When signaled by the pituitary gland in the brain via luteinizing hormone (LH), the testes, in the presence of adequate precursors, produce Testosterone.

Healthy young and middle-aged adults usually secrete about 5 to 25 micrograms of melatonin each night - at least 80 times less than is in the commonly sold 2 milligram (mg.) tablet or capsule. The amount of melatonin the body secretes tends to decline with age, a possible link with an age-related rise in difficulty sleeping.

Yes. MSM does occur naturally in the body in small amounts. It is probably synthesized by gut bacteria, and appears to have a function in the liver’s processing of toxic agents that enter the body from outside.

The testes receive chemical signals from the pituitary gland, which is located at the base of the brain. The pituitary gland receives signals from the hypothalamus. The hypothalamus secretes gonadotropin-releasing hormone (GnRH). This signals the pituitary gland to produce and secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH signals the testes to produce testosterone.

Not only does the amount of testosterone produced decline with age, the morning spike of testosterone seen in young men is also blunted in older men. The pituitary glands of older men also may produce less luteinizing hormone (LH), resulting in decreased testosterone production. Testosterone in aging men is more likely to bind to sex hormone binding globulin (SHBG), which reduces the amount of freely circulating testosterone that is available to the body.

Cortisol is a stress hormone. Your body produces cortisol in response to stress, physical, mental or emotional. This can include extremely low calorie diets, intense training, high volume training, lack of quality sleep as well as common daily stresses such as job pressures, fights with your spouse or being caught in a traffic jam.

Hair forms and grows inside a protective encasement called the follicle. The average person has approximately 100,000 scalp hair, this will vary depending on the color and texture of the hair. Hair grows in naturally formed follicular units of between one to four hairs. This recent discovery has helped create a new method of hair re-growth treatment called Follicular Hair Transplantation; this advanced form of treatment is offered at AHI clinics.

Both males and females produce testosterone (T) and Estrogen (E) naturally. However the amount of T and E produced varies between the two sexes. In this post I'll emphasize on the production of T in males [sorry ladies :)] which goes like this: When T level in the body falls bellow a certain set-point (set-point varies between individuals) the hypothalamus is stimulated to produce Gonadotropin Releasing Hormone GnRH).

Testosterone is a powerful anabolic hormone. That means it stimulates the body's development of muscle, bone, skin, and sex organs, along with masculine physical features, such as hair growth. Recently, scientists have discovered that testosterone also improves mental power, by enhancing visual and perceptual skills. In men, testosterone is produced in the testes, by a group of cells known as Leydig cells.

Mother Nature has not abandoned us nor made a mistake with our generation. Our foods, drugs, environmental pollutants and profit driven medical industries have brought on many of our ills. Progesterone deficiency, more specifically estrogen dominance (as Dr. Lee refers to it) is an unfortunate condition of industrialized countries. Since 1948 over 70,000 new made-made chemicals have been introduced into our environment, less than 3% have even been tested for toxicity.

The effect produced by the applicator-roller is equal to that produced by the applicator-plate, but the result is achieved much quicker. Besides, with the roller you can reach any place of the body. It is possible to work up the whole body with the roller for 2-3 minutes: the body will "burn", you will have "needle shower" consisting of a few millions of pricks. Using the roller, it is possible to warm the whole family after supercooling in 10 minutes.

Since ancient times men have searched for ways to increase their virility. Today, there are many popular medications that improve the physical factors (such as circulation) needed to sustain an erection. Yet many men do not realize that none of these medicines can work effectively without adequate testosterone in the body. That's because testosterone is, in a sense, your body's natural aphrodisiac. Only when there are sufficient levels are you able to feel and sustain sexual arousal.

Testosterone is life saving for AIDS patients suffering with AIDS wasting syndrome (AWS) in both men and women. Testosterone increases appetite, stimulates immune system and helps pack on muscular tissue. These medical uses of Testosterone to stimulate red blood cell production, improve immune system function and increase the appetite and ability to gain weight are most effective in these patients. Other uses include the stimulation of protein build up in major traumas such as burns and cancer.

A great amount of research has been devoted to understanding the way cocaine produces its pleasurable effects, and the reasons it is so addictive. One mechanism is through its effects on structures deep in the brain. Scientists have discovered regions within the brain that, when stimulated, produce feelings of pleasure. One neural system that appears to be most affected by cocaine originates in a region, located deep within the brain, called the ventral tegmental area (VTA).

The amount of electricity produced by the Acuscope is measured in microamps (millionths of an amp), an extremely tiny amount of current in comparison to the amount of electricity flowing from a wall socket. It has been scientifically proven that this level of current produces the most beneficial effect on the body's cells.

Just clean air. The Austin Air Cleaner does NOT produce OZONE, IONS, or NEGATIVE IONS. Ozone is active Oxygen and can be dangerous to people with respiratory problems, such as asthma and emphysema. Periodic vacumming of the four sides on the outside screen is the only maintenance required for the Austin Air Cleaner. Typically, the filter only needs to be changed every five years.

It produces XHTML compatible with the XHTML 1.0 specification. A cascading stylesheet is required for proper viewing with a modern graphical browser. Correct rendering of the HTML produced depends on the CSS support of the browser. A general-purpose stylesheet, html4css1.css is provided with the code, and is embedded by default. It is installed in the "writers/html4css1/" subdirectory within the Docutils package.
