Testosterone may help fight diabetes in baby boomer men

TOKYO — When Gary Wittert began looking for tubby male baby boomers to take part in a clinical trial last month, he got 800 volunteers in one day. The draw: free testosterone injections.

Wittert, a professor of medicine at the University of Adelaide, and his colleagues suspect the sex hormone known to increase libido and musculature could also help prevent a form of diabetes that tends to strike later in life and afflicts more than 330 million people worldwide.

The steroid, which cyclist Lance Armstrong admitted to using in winning seven Tour de France titles, could go from being popular among men “looking to spice up their sex lives” to becoming a mainstream therapy if the trial, the largest test of testosterone’s potential to fight diabetes, shows positive results, said Stuart Roberts, a health-care analyst with Bell Potter Securities in Sydney.

“The Wittert study will be the real kicker here,” Roberts said in a telephone interview. “This is what gets you away from the ‘snigger factor’ with testosterone. And, because testosterone is cheap and easy to make, it won’t be an impost to the health-care system.”

The study was discussed at the 10th International Congress of Andrology, which ran through Tuesday in Melbourne.

Testosterone, produced in men’s testes or replicated chemically, is already in demand.

Revenue from prescription sales in the United States grew tenfold to $2.2 billion since 2001. Newer topical gel formulations are spurring 20 percent-a-year growth in the market, which will reach $5 billion by 2017, Global Industry Analyst, a San Jose, Calif.-based research firm, said last April.

In Australia, where testosterone prescriptions are also climbing, demand is spurred by what David Handelsman, a professor of medicine at the University of Sydney, describes as an “anti-aging racket” targeting gullible men.

“They think testosterone is the essence of manhood and it will prolong their youthful vigor forever,” said Handelsman, whose research focuses on male reproductive health. “They’re persuaded because sex sells and anything to do with sex and reproduction is easy to market.”
