The effect of testosterone treatment on prostate histology and apoptosis in men with late-onset hypogonadism

Objectives: To investigate the effect of testosterone replacement therapy (TRT) on prostate histology and apoptosis in men with late-onset hypogonadism (LOH). Methods: The study included 25 men, having LOH with prostate-specific antigen (PSA) level of 4 ng/ml or less. All patients underwent transrec...

Description
Summary:Objectives: To investigate the effect of testosterone replacement therapy (TRT) on prostate histology and apoptosis in men with late-onset hypogonadism (LOH). Methods: The study included 25 men, having LOH with prostate-specific antigen (PSA) level of 4 ng/ml or less. All patients underwent transrectal ultrasound guided prostate biopsy at baseline, and received testosterone undecanoate treatment for 1 year. Prostate biopsy was repeated at the end of 1 year of testosterone therapy. In addition to clinical and biochemical parameters, prostate histology and apoptotic index (AI) were compared before and after the TRT. Results: The mean serum total testosterone significantly increased from 178.04 ± 51.92 to 496.28 ± 103.73 ng/dl (p = 0.001). No significant differences were observed in serum total and free PSA level, prostate volume and maximal urinary flow rate. There were also no significant differences in AI, stroma/epithelial cells ratio, Ki-67 positive cells and atrophy score of prostate tissue before and after the TRT. Conclusions: This study demonstrated that TRT did not affect serum PSA level, prostate volume and maximal urinary flow rate. This study also suggests that TRT does not cause the risk for prostate cancer development, because of no significant differences in prostate histology after TRT.
