Evaluation of long-term treatment patterns in hypogonadal men using topical testosterone replacement therapy or short-lasting injections, "Beyond the Abstract," by David Muram, MD

BERKELEY, CA (UroToday.com) - Recent developments in the field of hypogonadism and testosterone replacement therapy (TRT) have led to an increased public awareness for this condition. While efforts to reach consensus on how to best identify men with substantial disease burden from low testosterone continue, hypogonadal men benefit from testosterone replacement therapy. However, to derive benefits from treatment, patients should continue therapy for at least 3 months.[1] Testosterone has a significant effect on sexual function. Not surprisingly, sexual complaints are often what drive patients to seek medical care, and are also the yardstick patients use to judge the adequacy of therapeutic response. Sexual symptoms may take up to three months to improve, and reach a plateau at 12 weeks.[1, 2] Cognitive responses and physiologic changes in body mass (increase in lean body mass, and decrease in adipose tissue) may take longer than 12 weeks.[3]

Evidence-based guidelines from specialty societies generally recommend follow-up at 3 – 6 months.[1, 4, 5] The patient’s response over time to testosterone replacement serves as the foundation for this recommendation. While this recommendation is well founded, it does not take into consideration patient motivation and expectations.

Our study of adherence and persistence to therapy after initiation of TRT (both topical and short acting parenteral therapy) has shown that by the first month many patients have either failed to initiate or have decided not to renew their initial prescription.[6] By three months, the time point recommended by the guidelines for re-evaluation, nearly 50% of patients on topical TRT and 70% of patients on short acting parenteral TRT have discontinued therapy. These results, particularly if confirmed by others, would suggest that there is a need for interventions sooner than three months. Setting proper patient expectations at the outset, concerning the response to therapy, will hopefully allow better adherence and treatment outcomes. Re-evaluation shortly after initiation of therapy would allow more timely adjustment of dose to achieve optimal serum levels and allow clinicians to review and reinforce appropriate patient expectations and outcomes.
