Drooping testosterone levels probably don’t cut years off a man’s life, although earlier studies had suggested they might, according to a new report. Instead, decreases in the male sex hormone may simply be a sign of overall health status, which also dips with age, researchers say. The findings come in the wake of surging interest in testosterone’s role in men’s sex drive, their mood and thinking, and even early death. While drug companies refer to “low T” as a treatable medical problem affecting millions of American men, critics say they are trying to make a buck by turning normal aging into a disease.
