Testosterone is a male hormone and well know to build up muscle also can help to reduce body fat. Then over the years there’s growing interest on “testosterone replacement” therapy as a hormone replacement therapy for men who are aging normally. The idea is simple that replacing natural testosterone hormone can help men to robust and possibly healthier as they’re age.

A recent study which held in Australia found that giving “testosterone replacement” to a healthy, non-obese men during the study, about a year helped them avoid some of the muscle loss and fat gain associated with aging. The men were all over 55 years of age but were not “deficient” in testosterone when they started the study.

The study also suggests that “testosterone replacement” could be a help to men. Especially for some men who has testosterone deficiency, it can help in improving bone strength and reducing cardiovascular risk, translate to naturally aging men.

Unfortunately some expert still doubt it. They say the results of the study and others like it are giving too many people an excuse to claim that testosterone and human growth hormone replacement is a fountain of youth for men.

“No one has ever shown that otherwise healthy men get any healthier if they gain some muscle or lose some fat on testosterone therapy,” say R. Blackman, MD, a professor of medicine at Johns Hopkins University in Baltimore. At the same time, gains in muscle mass haven’t even been shown to improve older men’s ability to perform normal activities like climbing stairs or carrying groceries.

Without proof of improved strength or help in avoiding disease, all that can be concluded now is that the benefits of testosterone therapy are “absolutely cosmetic,” he added

Blackman, say that they’re worried about growing prescriptions for testosterone, along with evidence of growing gray-market purchases over the Internet. That use is at least in part fueled by studies like the Australian study in 60 men. “Testosterone does show some benefits in men who are clinically deficient. But in men whose testosterone wanes normally, the benefits are unproven,” say Glenn R. Cunningham, MD, a professor of medicine at Baylor College in Houston.

“We don’t treat those men,” Cunningham says. “Most of the clinical trials in this area are small. You don’t get the information you need to truly address effectiveness and safety in studies this small.”

In the meantime, Blackman points to an attitude that he says differs between the U.S. and Europe, where testosterone therapy is not nearly as popular. In the U.S., both men and women tend to place a high “prize” on appearance, sometimes with unhealthy consequences, Blackman says.

In Europe the attitude is: “Aging is part of the normal life cycle. Live with it.”
