Is male menopause a myth? Maybe not, says Laurence M. Demers, Ph.D., professor of pathology and medicine and director of clinical chemistry and laboratory testing of automated MS Hershey Medical Center at Penn State University. According to Dr. Demers, there seems to be a physiological basis - as it is for women - known by what virile as andropause or menopause. Dr. Demers discuss the issue at the 53rd Annual Meeting of the American Association for Clinical Chemistry (AACC), at McCormick Place in Chicago, July 30 - August 2, 2001 instead.
Male menopause is a phenomenon that many women are observed at, in the last decades. But the transition from social observation of scientific analysis, chemists, scientists and clinicians to learn more about the relatively new concept of andropause, which can be identified by the male testosterone.
Why are so many men on Viagra?
The question of the testosterone of men has received increased attention in recent years due to the increasing use of Viagra. "Why are so many men on Viagra?" Dr. Demers request. "There are many men with libido problems?"
Researchers suggest that women experience menopause due to declining estrogen levels, men can live their own version - Andropause - with the lowest testosterone levels. Symptoms that men can result in your doctor to check your testosterone male infertility and decreased libido.
Most doctors initially test the level of total testosterone. Typical concentrations are from 250 to 800 ng / dL. A score below 250 indicates low testosterone levels. For someone with low testosterone levels, further testing is required. If other tests to determine the bound from free testosterone and testosterone to albumin levels are also is low, the doctor will try to identify the cause. Low testosterone may be the result of either the testes or pituitary gland dysfunction.
Dr. Demers and colleagues found that the level of testosterone and androgen precursor steroids can vary between different ethnic groups.
- A study of Portuguese, Latin, and Asian women noted for example that the average level of testosterone in Portuguese subjects was about 500, of the Americans, ~ 450, and the Asian population, ~ 400
- Differences were observed with androgen steroid precursors such as DHEA. Asian Men usually have less facial and body hair than Americans, which is usually less than the Portuguese.
- There is also a lower incidence of prostate cancer in Asian men, which the researchers suggest that testosterone may be a "driver" for prostate cancer, but estrogen may be a "pilot" for cancer Breast.
- This theory is supported by evidence that African-American men have a higher testosterone levels, and the highest rates of prostate cancer as well.
"This is all preliminary data, but," says Dr. Demers, "and must be strictly validated scientifically."

The American Association for Clinical Chemistry (AACC) was founded in 1948 and is the most prestigious professional association in the world for clinical biologists, clinical and molecular pathologists, and other related fields. Biologists are clinical specialists in all areas of laboratory testing in humans, including infectious and genetic diseases, DNA, and the presence of tumor markers. The primary professional commitment to the clinical laboratory is the understanding and use of laboratory tests to effectively detect, manage and treat diseases in humans.
