Can intense exercise reduce testosterone levels

Can intense exercise reduce testosterone levels?

Another stay-healthy strategy that can undermine your Testosterone is intense exercise. If you're a hardcore runner, swimmer, cyclist or the like, you may well be suffering from mild to moderate "gonadopause" - the male equivalent of female athletes' failure to menstruate during periods of heavy workouts. In a study of men who run 130km or more per week, Cumming found significantly lowerthan- average T levels - in the bottom 20 percent of the normal range. The study indicates that this drop was related not to any type of impaired testicular production, but rather to a decrease in the pituitary glandï¿½??s ability to signal the testicles to make testosterone. "The signals in high-mileage runners were less frequent and less concentrated," says Dr. David Cumming.
