We previously demonstrated that blocking the conversion of testosterone to 5\u03b1\u2010dihydrotestosterone (DHT) limits its ability to impair healing, suggesting that DHT is a more potent inhibitor of repair than is testosterone. The present study aimed to delineate the central mechanisms by which androgens delay repair. Whilst the contractile properties of neither rat wounds\n                    <jats:italic>in vivo<\/jats:italic>\n                    nor fibroblast\u2010impregnated collagenous discs\n                    <jats:italic>in vitro<\/jats:italic>\n                    appeared to be influenced by androgen manipulations, the global blockade of DHT biosynthesis markedly accelerated re\u2010epithelialization of incisional and excisional wounds and reduced local expression of \u03b2\u2010catenin, a key inhibitor of repair. Moreover, DHT retarded the\n                    <jats:italic>in vitro<\/jats:italic>\n                    migration of epidermal keratinocytes following scratch wounding. By contrast, it failed to influence the migratory and proliferative properties of dermal fibroblasts, suggesting that its primary inhibitory effect is upon re\u2010epithelialization. These novel findings may be of particular significance in the context of chronic ulceration, for which being male is a key risk factor.
