Diagnosis of hypogonadism: symptoms, signs, tests, and guidelines

Show Summary Details


Hypogonadism is a clinical syndrome complex which comprises symptoms ± signs as well as biochemical evidence of testosterone deficiency. The clinical presentation of hypogonadism depends on the age of onset and whether or not it is pre- or post-puberty. Symptoms of hypogonadism, especially in older men, are non-specific. Morning total testosterone is a good predictor of hypogonadism, except in borderline cases where free or bioavailable testosterone assessment can be more sensitive. Published guidelines have aided clinicians in the diagnosis of hypogonadism, especially in the interpretation of testosterone levels.
