title: Undetectable prostate-specific antigen in aging men.
abstract: Undetectable prostate-specific antigen was found in three aging men despite the absence of any prostatic surgery or exogenous hormonal deprivation. Clinical and elementary hormonal workup revealed the presence of secondary hypogonadism. This finding confirms the hormonal dependency of this prostatic marker and may, in some cases, explain the discrepancy between prostatic volume and the value of serum prostate-specific antigen.
