title: Study clarifies associations between hypogonadism and health in aging men.
abstract: Tajar and colleagues present the associations between moderate and severe hypogonadism, symptoms of androgen deficiency and the prevelence of end-organ evidence of androgen deficency in 2966 older men in the European Male Aging Study.
