The anatomy, structure, and function of the tissue adjacent to the anterior vaginal wall and surrounding the urethra has not been characterized sufficiently in the context of its role in female sexual function. This study histologically characterized the overall morphology as well as the location of the innervation and glandular in periurethral tissues collected from female cadavers.
High heart rate (HR) is an independent risk factor for erectile dysfunction (ED) The I(f) (Ifunny) or hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are involved in synaptic transmission and neuronal excitability under physiological conditions. The I(f) channel inhibitor ivabradine controls HR in the sinoatrial node and reduces myocardial oxygen demand without inducing hypotension. Only one study has explored HR reduction with ivabradine-improved ED parallel to decreased oxidative stress and penile fibrosis in atherosclerotic plaque load in ApoE-knockout mice.
To evaluate the effect of local delivery of lipoic acid (LA) and 4-hydroxy-2,5,6-triaminopyrimidine sulfate (HTAP) by polymeric microspheres in the bilateral cavernous nerve injury (BCNI) in the rat. LA is an antioxidant previously shown to improve neurogenic and endothelial cell dysfunction in the corpus cavernosa of diabetic rats through reduction of reactive oxygen species. HTAP is a novel, not yet extensively studied, multifunctional antioxidant with the potential to moderate peripheral nerve damage by similar mechanisms.
