Low Testosterone

Testosterone is a significant male hormone, responsible for producing and maintaining what is considered normal male characteristics. Beginning from puberty, testosterone stimulates physical changes such as the growth of facial and pubic hair, the lowering of the voice, the growth of the penis and the testes, increase in muscle mass and strength, and growth in height. Continuing through adulthood, testosterone maintains the sex drive, sperm production, bone mass, muscle mass, hair patterns, and many other important functions within the male body.

The body produces testosterone through the use of chemical signals sent to two primary locations in the body--the hypothalamus and the pituitary gland. The pituitary, located at the base of the brain, produces the hormone, while the hypothalamus controls the amount that is produced. In this finely balanced system, the brain senses the need for either more or less testosterone. If the levels of testosterone become low, the brain signals the pituitary gland to secrete a follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The LH signals the testes to produce more testosterone. If the levels of testosterone become too high, the brain signals the pituitary to make less LH, thereby slowing the production of the hormone.

In the past, hormone therapy research and medicine was staunchly based within the realm of women's health, specifically in the study of menopause. This is no longer the case. In recent years many advancements have been made in the research of low testosterone and its repercussions on the male health system. Today leading researchers in the study of low testosterone perceive that between 20 and 50 percent of healthy men between the ages of 50 and 70 years suffer from low testosterone levels.

Male Menopause: Fact or Fiction?
The term given to define this phenomenon is andropause, at times considered to be the "male menopause". This is a bit misleading, as there are definitive differences between menopause and andropause, such as the rate at which the symptoms appear. Menopause is a change in the female body, clearly marked by the discontinuation of the menses, or period. Andropause occurs over a much longer duration, and there is not one major symptom to point out its existence. It is clear that both menopause and andropause occur naturally in the life cycles of men and women, usually beginning sometime during the fourth and fifth decades of life. During the onset of andropause, the testosterone levels will drop below what is considered normal.

Although there is not a specific symptom signifying the onset of andropause, there are several clues to look for. As the testosterone levels fall, the mass and strength of muscle decreases, signs of osteoporosis may set in, erectile dysfunction and/or decreasing sex drive is plausible, increased body fat, memory loss, difficulty sleeping, and possible mood swings can also surface.

The evidence of how low testosterone levels can effect the male health system has led medical researchers to surmise that this syndrome has gone misdiagnosed for far too long. It is estimated that as many as five percent of all males may be at risk for low testosterone. As this is a fairly new field of research, it is probable that the actual numbers are higher.

Other studies into the effects of low testosterone are finding connections between the levels of testosterone and risk of heart disease. Men found with higher levels of testosterone are showing lower levels in blood insulin counts. This is recognized as vital for the prevention to heart disease and heart attacks.

It is estimated that 4.5 million American men are at risk from low testosterone levels. Research is also showing that the majority of those at risk do not understand how low testosterone can adversely affect their overall health. Today there are several options to reverse the effects of low testosterone levels, increasing one's chances of a longer, healthier life.
