Does testosterone restore diabetes-induced erectile dysfunction and sildenafil responsiveness in two distinct animal models of chemical diabetes?
In two models of diabetes T deficiency underlies biochemical alterations leading to ED. Normalizing T in diabetes restores nNOS and PDE5, and reinstates sensitivity to relaxant stimuli and responsiveness to sildenafil.
In this rat hypoxia model, endotoxin pretreatment ameliorated the hypoxia-induced inflammatory response as well as suppressing the effects on arterial oxygenation, anaerobic metabolism and NE stimulation.
