The significance of testosterone for the male sexual function is apparent to most Life Extension customers. New insights, however, underscore the critical role testosterone plays in maintaining youthful neurological structure, alleviating depression, as well as inducing fat loss in those who are unable to reduce body weight regardless of diet and exercise.

Recent studies have demonstrated that low testosterone in men is strongly associated with metabolic syndrome, type 2 diabetes, cardiovascular disease (Miner and Seftel 2007), and an almost 50% increase in mortality over a seven-year period (Malkin et al 2010).

Restoring testosterone to youthful ranges in middle-aged, obese men resulted in an increase in insulin sensitivity as well as a reduction in total cholesterol, fat mass, waist circumference and pro-inflammatory cytokines associated with atherosclerosis, diabetes, and the metabolic syndrome (Kapoor et al 2006, Malkin et al 2004, Heufelder et al 2009). Testosterone therapy also significantly improved erectile function (Fukui 2007) and improved functional capacity, or the ability to perform physical activity without severe duress, in men with heart failure (Malkin et al 2007).
