Low Testosterone Common Among Older Men
In the study, published in the International journal of Clinical Practice, researchers looked at the prevalence of low testosterone levels among more than 2,100 men aged 45 and over who visited one of 130 different primary care practices in the U.S. for any reason during a two-week period.
Overall, the results showed that more than a third of the men had low testosterone levels (less than 300 ng/dl total testosterone or were on current testosterone treatment). The odds of having low testosterone were:
- 2.4 times higher for obese men
- 2.1 times higher for men with diabetes
- 1.8 times higher for men with high blood pressure
Men with prostate disease, and were also more likely to have low testosterone than healthy men.,
Researchers say low testosterone is often overlooked in men because they frequently ignore their symptoms or attribute them to other causes, such asor diseases associated with aging.
Researcher Thomas Mulligan, MD, of VAMC GRECC and the division of geriatrics at the University of Florida, and colleagues say the high prevalence of low testosterone in this study warrants consideration by primary health care providers.
However, there is controversy about the risks associated with the long-term safety of testosterone replacement therapy, especially among older men.
