Age-Related Testosterone Deficiency Merits Treatment

Abstract

The negative effects of testosterone deficiency (TD) on human health and quality of life are well demonstrated, including signs, symptoms, metabolic syndrome, obesity, and increased mortality. Recently, substantial evidence emerged, demonstrating the benefits of testosterone therapy in men with classical and “age-related” hypogonadism. The US Food and Drug Administration (FDA) opposes testosterone therapy in men with age-related hypogonadism but not in men with classical hypogonadism. The FDA acknowledges that TD merits treatment, but the FDA made an artificial distinction between diagnoses where T treatment is warranted and others where the underlying diagnosis is unknown, and treatment is unwarranted. The FDA labeled the unknown category as “age-related.” Since the FDA is unable to demonstrate that one group differs in benefits or risks from the other, there are no bases for this distinction. This action by the FDA is not based on scientific or clinical evidence. There is no evidence that the response to testosterone therapy of “age-related” hypogonadism occurs via different physiological or biochemical mechanisms than those historically recognized conditions. Also, there is no evidence that “age-related” hypogonadism responds less well to testosterone therapy than “classical” hypogonadism. More importantly, there is no scientific or clinical evidence to suggest that the risks of testosterone therapy in men with “age-related” hypogonadism are worse or different for men with “classical” hypogonadism. For these reasons, we disagree with the FDA position on testosterone therapy in age-related hypogonadism.
