Testosterone therapy may not improve sexual function or quality of life in men with lower levels of the sex hormone, researchers, including one of Indian-origin, have found.

The three-year study from Brigham and Women’s Hospital (BWH) in US found that testosterone administration had no effect on the progression of hardening of the arteries in older men with low to low normal testosterone levels and did not significantly improve sexual function or health-related quality of life.

“The results of this trial suggest that testosterone should not be used indiscriminately by men,” said corresponding author Shalender Bhasin, director of BWH’s Research Programme in Men’s Health: Ageing and Metabolism.

“We find that men with low and low normal testosterone are unlikely to derive benefits in terms of sexual function or quality of life, two reasons why men may seek testosterone therapy,” Bhasin said.

“And although we find that testosterone did not affect the rate of hardening of the arteries, we need long-term data from large trials to determine testosterone’s effects on other major cardiovascular events,” he said.

Testosterone, a hormone primarily secreted by the testicles, plays a key role not only in male reproductive tissues but also in muscle growth, bone mass and body hair.

As men get older, their testosterone levels naturally decline – on average by one per cent a year after age 40.

The research team enrolled more than 300 men over the age of 60 with total testosterone levels between 100-400 nanograms per decilitre (ng/dL) (low to low normal range) and measured two indicators of atherosclerosis: calcium deposits in the arteries of the heart (coronary artery calcification) and the thickness of inner lining of the carotid arteries that supply blood to the brain (common carotid artery intima-media thickness).

To measure secondary outcomes of sexual function and health-related quality of life, the research team had participants also completed a 15-item questionnaire.

Participants applied a testosterone or placebo gel daily for three years.

“Many men, as they get older, experience a decline in testosterone and in sexual function and vitality. But our study finds that taking testosterone, when levels are in the low to low normal range, may not improve sexual function or quality of life,” Bhasin added.

The study was published in the Journal of the American Medical Association (JAMA).

    It should be noted that this article largely fails to clearly clify what is meant by "older men" -- in fact the word "older" is really glossed over, the one time it is used here. It also fails to address what is meant by "improved ual function" or "quality of life," both of which are extremely subjective matters. It also fails to mention that transdermal gels are probably the worst, most ineffective form of testosterone replacement therapy. One would wonder why such a study is being based solely on the results of the worst possible form of therapy for the given medication. They could have been accurate and studied the results for placebo vs each individual route of administration for testosterone, of which, injections are still the best. This narrow scope is in place entirely on purpose, so that the deck is stacked, and the report is more likely to have the results that these particular researchers wanted it to have. This is a poorly written article about a poorly done study designed to keep men weak, docile, fat, lazy consumers. Don't fall for it, men. Get your levels tested and get on a TRT program. This is 2015. Take advantage of the state of medical science and the availability of exogenous testosterone. Get yourself to OPTIMAL testosterone levels and BE THE BEST MAN YOU CAN BE. DO NOT LET SOCIETY EMASCULATE YOU.
