Importance of hypogonadism and testosterone replacement therapy in current urologic practice: a review.

Evaluation of potential candidates for testosterone replacement therapy (TRT) includes a complete medical history, physical examination, and hormonal screening. The choice of testosterone assay is important in clinical decision making. TRT should, in theory, approximate natural endogenous production of the hormone. There is no apparent association between TRT and the development of prostate cancer. The administration of exogenous testosterone is not a means of reversing the aging process in men with normal testosterone levels, but it may offer considerable benefit for those with hypogonadism.
