title: The androgen-deficient aging male: current treatment options.
abstract: All delivery forms of testosterone should be equally efficacious in treating the androgen-deficient aging male if adequate serum testosterone levels are obtained. The testosterone preparations available in North America include the oral undecanoate, injectable testosterone esters, the scrotal patch, the nonscrotal transdermal patch, and the transdermal gels. Selection of a specific testosterone preparation for replacement therapy depends on many factors, including the magnitude and pattern of serum testosterone levels produced, side effects of the particular formulation, reversibility if an adverse event should occur, convenience of use, cosmetic issues related to the preparation, and cost. In addition, potential adverse effects of testosterone therapy applicable to all forms of testosterone delivery, such as fluid retention, gynecomastia, polycythemia, worsening of sleep apnea, change in cardiovascular-disease risk, or alterations in prostate health, need to be considered both prior to therapy and during treatment monitoring.
