[QUOTE="Nelson Vergel, post: 272937, member: 3"] One of the major concerns for the prescription of medications containing testosterone (T) in the aging men with T deficiency (TD) is prostate disorders (such as benign prostatic hyperplasia, BPH) and their related symptoms (lower urinary tract symptoms, LUTS). This is because prostate is an androgen-responsive gland; however, the androgen dependence of prostate growth, well demonstrated in earlier phases of life, has no clear evidence in late adulthood and senescence. In fact, after the age of 40 years, BPH becomes increasingly more prevalent. On the other hand, in men older than 40 year, a progressive decline in T is observed. These epidemiological data are a starting point for questioning a putative detrimental role of T on the prostate health in the ageing man. In addition, even the administration of supraphysiological doses of T in adult healthy men with or without dutasteride did not result in a significant change in prostate volume over 20 weeks of [b][url=https://www.excelmale.com/wp-admin/post.php?post=20480&action=edit&classic-editor]treatment[/url][/b].[1] Based on this evidence, it is not surprising that epidemiological studies failed to demonstrate that BPH is associated with higher serum T.[2] Conversely, there is even an evidence of a negative relationship between T and BPH.
