The effect of vascular endothelial growth factor and adeno-associated virus mediated brain derived neurotrophic factor on neurogenic and vasculogenic erectile dysfunction induced by hyperlipidemia.

Abstract PURPOSE: We examined neurogenic and vasculogenic erectile dysfunction associated with hypercholesterolemia and evaluated vascular endothelial growth factor (VEGF) and adeno-associated virus (AAV) mediated, brain derived neurotrophic factor (BDNF) for potential treatment. MATERIALS AND METHODS: A total of 21, 2-month-old male rats were fed a 2% cholesterol diet and another seven were fed a normal […]

Vascular endothelial growth factor (VEGF) gene therapy using a nonviral gene delivery system improves erectile function in a diabetic rat model.

Abstract Erectile dysfunction (ED) is a cause of decreased quality of life in more than 70% of diabetic men. Vascular endothelial growth factor (VEGF) has shown to improve overall endothelial and smooth muscle cell dysfunction in models of ED. We describe a novel technique for nonviral, in vivo gene transfection of VEGF in the rat […]

Intracavernosal vascular endothelial growth factor (VEGF) injection and adeno-associated virus-mediated VEGF gene therapy prevent and reverse venogenic erectile dysfunction in rats.

Abstract Penile veno-occlusive dysfunction (venogenic erectile dysfunction) is a common cause of erectile dysfunction (ED). We investigated whether vascular endothelial growth factor (VEGF) can be used to prevent and reverse venogenic ED in a rat model. Pharmacological cavernosometry was developed and validated using adult male rats with either arteriogenic or venogenic ED. Castrated animals were […]

Erectile dysfunction and the cardiovascular patient: endothelial dysfunction is the common denominator.

Abstract Erectile dysfunction (ED) is a common condition and studies predict that it will become even more common in the future. There is increasing evidence to suggest that it is predominantly a vascular disease and may even be a marker for occult cardiovascular disease. The common pathological process is at the level of the endothelium, […]

Erectile dysfunction and subsequent cardiovascular disease.

Abstract CONTEXT: The risk factors for cardiovascular disease and erectile dysfunction are similar. OBJECTIVE: To examine the association of erectile dysfunction and subsequent cardiovascular disease. DESIGN, SETTING, AND PARTICIPANTS: Men aged 55 years or older who were randomized to the placebo group (n = 9457) in the Prostate Cancer Prevention Trial at 221 US centers […]

The impact of vascular risk factors on erectile function.

Abstract The main cause of erectile dysfunction is organic in nature, with vascular etiologies being the most common risk factors. The incidence of erectile dysfunction increases with the number of vascular comorbidities such as hypertension, diabetes, hyperlipidemia, smoking and atherosclerosis. The earliest signal of endothelial damage in men with vascular risk factors is the manifestation […]
