title: The diagnosis of late life hypogonadism.
abstract: The diagnosis of late life hypogonadism is controversial. For the purposes of discussion, it is suggested that treatment of late life hypogonadism requires the presence of symptoms, a low level of circulating free or bioavailable testosterone level and a positive response to treatment. While this may appear to be a radical proposal, we believe it represents the most rigorous scientific approach to the diagnosis of late life hypogonadism at the present time.
