Erectile dysfunction (ED) means inability to achieve and maintain an erection long enough to engage in sexual intercourse [1, 2]. Erectile dysfunction is an obvious cause of a decline in the overall quality of life [9]. For the implementation of erectile function in the body responsible psychological, neurovascular and endocrine factors. [1, 2] Sexual arousal causes release of relaxing neurotransmitters from nerve endings and endothelial cells of the penis resulting in the relaxation of smooth muscles of arteries and arterioles, which inevitably leads to filling with blood and expansion of corpora cavernosa. [2, 11] During erection subtunicular plexus between the trabeculae and the tunica albuginea become compressed, resulting in almost total occlusion of venous outflow. [9] During the full-erection phase, when penis is at 90 degrees perpendicular to the abdomen, intracavernous pressure reaches 90-100 mm Hg, while the blood volume in the erect penis may exceed that in the soft penis by 8 times [10, 11].
