Hormone replacement Up-to-date. Clinical practice of androgen replacement therapy

Abstract

Androgen replacement therapy (ART) should be considered for initial treatment of late-onset hypogonadism. Intramuscular injection of testosterone enanthate is frequently used for ART in Japan. Prior to ART, it is necessary to measure prostate specific antigen (PSA) in order to rule out prostate cancer, and hematological examination should be performed periodically during treatment to monitor for polycythemia.
