Fundamentally, the Endocrine society male hypogonadism guidelines definition considers low T in this context to be marker of the underlying poor health, and hence does not support prescribing of testosterone in such settings.

Also, a man with a missense mutation of the SHBG gene who had complete deficiency of SHBG and very low TT concentrations was reported to have normal FT and gonadotropin levels, normal male reproductive development, and normal testes size and spermatogenesis, suggesting a limited role of SHBG in male sexual development and spermatogenesis However, clinicians should only use the prostate cancer risk calculator for men 55 to 95 years old; furthermore, clinical experience with this tool is limited especially in men with hypogonadism and criteria for urological referral have not been established. Therefore, assessing men for T deficiency should include a general health evaluation to exclude systemic illness, eating disorders, excessive exercise, sleep disorders, and use of recreational drugs and certain medications e. Because of the lack of consensus on the extent to which hypogonadism is an important public health problem, as well as the lack of data on the performance characteristics of candidate screening tools, we do not recommend population screening.

In hypogonadal men who have osteoporosis, are not at high risk of bone fracture, and are being started on T-replacement therapy, clinicians may consider deferring treatment with approved osteoporosis drugs until they have evaluated the response to T replacement by repeating BMD tests of the lumbar spine, femoral neck, and hip after 1 to 2 years of T therapy.
