Penile hypercoagulability during erection: a possible predisposing factor to ageing penile vascular changes

Haemostatic changes in the penile and systemic blood during erection were studied in the Chacma baboon. Dynamic hypercoagulability developed in the penile blood and fibrin was deposited on the endothelium of the penile artery and trabeculae during erection. These suggest that penile hypercoagulability predisposes to ageing penile vascular changes.
