26.What is a reasonable timeline to begin to observe improvements in the signs and symptoms of testosterone deficiency?
*Following the initiation of testosterone therapy, serum concentrations of testosterone are known to correct earlier than the symptomatic, structural, and metabolic signs associated with TD.76,77 As such, patients should be counseled that symptom response will not be immediate. Expectations for treatment response should be established with each patient. Patients can anticipate improvements in many of the common symptoms of TD (libido, energy levels, sexual function) after 3 months of treatment or longer. Metabolic and structural (body composition, muscle mass, bone density) changes may take upwards of 6-months. 77 In addition, patients should be counseled that diet and exercise in combination with testosterone therapy are recommended for body composition changes.
*Appreciating this pattern of response to testosterone therapy is fundamental when determining the impact of treatment and the appropriate timing of follow-up evaluations while on therapy. For example, if patients undergo a symptom review and measurement of testosterone levels too early (< 3 months), it may lead both physicians and patients to conclude that the treatment has not been impactful (i.e. normal levels of testosterone without symptomatic/structural/metabolic benefit). However, if the same assessment was scheduled 3-6 months after the initiation of therapy, the clinical response tends to be more reflective of normalized levels of serum testosterone.
