Testosterone and Anti Aging

Testosterone, HGH treatments gaining popularity for anti-aging uses.
The Los Angeles Times (1/18, Worth) reported that "increasing numbers of men...are turning to testosterone and human growth hormone (HGH)" in an effort to "look younger, be healthier, and feel more vital later in life." Testosterone prescriptions in the US "jumped to 3.3 million" in 2008, from 64,800 in 1999. However, "it is unclear whether the issues associated with aging in men -- decreased sex drive, less energy, cognitive impairment, and reduced muscle mass -- are due to a decrease in testosterone or to other changes that come with aging," researchers say. The National Institute on Aging says more research is needed on testosterone treatment for most issues, and the institute "cautions against using growth hormone therapy for anti-aging purposes."
