Yet another study demonstrating that the “villain of all males around the world” – the dastardly androgen dihydrotestosterone (DHT) – actually is, in all likelihood, beneficial for males, at least when it comes to their cardiovascular health. However, since CVD is one of the risk factors for prostate enlargement/cancer (which DHT ostensibly causes), the study below raises (again) serious doubts that DHT is a causative factor in prostate disease as well. I wonder how much longer can the charade known as the androgen hypothesis continue before the general public realizes it is been had.

“…Results: Although concentration of testosterone was not different between young and older group, it was demonstrated that DHT, DHEA-S, AE and ADG were significantly lower in older men in comparison to young men (p < 0.01). Interestingly the most surprising difference was found for DHT concentration, that was as much as 61 % lower in aged men that displayed significantly higher values of cIMT, AI, crPWV and SI (p < 10-4), suggestive of arterial stiffness. Furthermore, DHT was negatively correlated to all arterial wall parameters (cAI, crPWV, SI and cIMT), c-reactive protein (CRP) and hyaluronic acid (HA) concentration, as well as positively correlated to markers of endothelial function (MNA and 6-keto-PGF1α) in all studied individuals (n = 23). Conclusions: We have shown that ageing leads to a significant decrease in DHT concentration that is accompanied by impaired arterial wall characteristics and worsened endothelial function. Therefore more attention should be paid to the DHT, DHEA-S and ADG concentrations as a biomarkers for vascular dysfunction in ageing men.”
