The Importance of Having Testosterone- Midwestnutrition.com

Posted


Testosterone is an extremely important hormone for both men and women.
This importance begins at conception. It is in fact required to make conception a reality in the first place.

Testosterone is elaborated most heavily in the male, during the rapid period of a boy's maturation. This generally starts at age 11-14 for most boys, and ends by age 16-19. Testosterone has been well-studied from infancy up through adolescence, and medicine is becoming more interested in it's benefits for aging males and females. A man has a total testosterone about 10 times higher than a woman.

In men, testosterone is the major androgen and surprisingly, may start to decline at age 25. Those with a decline in testosterone, can usually get dramatic clinical benefits, once their total testosterone levels are restored to normal range (generally 300-1000 ng/dl) and the bio-available testosterone to 120 to 600 ng/dl. In earlier literature a less accurate method of testing referred to "free" testosterone. The bio-available testosterone can be calculated by knowing sex hormone binding globulin (SHGB), albumin (loosely-bound protein) and testosterone. The bio-available testosterone is considered the most accurate measure, because it is the active portion that exerts the most benefits to the body.Growth hormone has probably garnered more medical stature and attention, than deserved. In fact, in the very near future, men over the age of 50 will be encouraged by their physicians to take supplementary testosterone with growth hormone and other supporting hormones. Physicians are becoming much more aware of symptoms that may be related to testosterone decline, low levels and outright deficiency.

In the early 50's, science discovered that testosterone improved Nitrogen balance, increased muscle mass and(when adequate calories and protein were available), even helped repair damaged bones and ligaments. As it relates to my area of medical study, extending health, energy, strength and function as we age, it's extremely important. A study on men and testosterone was done way back in 1944, by Heller and Myers. After only three weeks of therapy, 20 men, all treated for low testosterone levels and related symptoms, showed enormous improvement in problems with insomnia, depression, being emotional labile (crying episodes), suicidal thoughts/tendencies, inability to concentrate, heart palpitations, headaches, fatigue, muscle pains, urinary problems, general energy, vigor and loss of normal sexual function. Even in the 1960s, some studies showed testosterone lowered cholesterol, improved cardiac function, abnormal EKGs in cardiac patients, relieved chest angina (pain) and helped decrease clogged leg and heart arteries. Once more, when bio-available testosterone levels were restored to normal, men had less atherosclerosis, or hardening of the arteries. In many diabetics, testosterone administration improved diabetic nephropathy, (having to do with small blood vessels in the eyes), lowered insulin requirements and enhanced glucose tolerance. Testosterone, of course, is present in both sexes, and although it is considered a sex hormone, it contributes to, and is essential for, many functions throughout your body.

Testosterone is either bound or bio-available. Blood tests measure free, bio-available, and total testosterone. Testosterone is the critical hormone that modulates so many functions, that it is called the King of all hormones. Testosterone is produced in large quantities in the testes and adrenals in young males. A woman's ovaries produce testosterone and smaller amounts from the adrenals to provide energy, libido and a feeling of well-being. Women report better nipple and clitoral sensitivity, greater sexual function, less depression, and less beast cancer rates. A woman who has had her ovaries removed, not only will need estrogen and progesterone, but also testosterone replacement to feel right. Male teenagers and young adults, have large increases in Bio-available testosterone, followed by a gradual decrease after about age 20-25, with a steady, slow decline, decade by decade, especially of Bio-available T, which is most critical.
In certain (rare) instances, men can maintain high testosterone at the upper end of the normal scale into their 50s, 60s and even 70s. In Okinawa, Japan, men and women ages 70 to 100 have significantly higher testosterone levels than men and women in the USA. Once more several studies show that farmers and blue collar workers, (like physical laborers), have an average testosterone higher than white collar workers. Why? Exercise and the diet of farmers or laborers gives them lower body fat. People with more body fat tend to produce higher quantities of estrogen that compete with or suppress normal testosterone activity.
