Psychological and physiological factors commonly provoke erectile dysfunction, but there can be some more reasons. According to the outcomes of clinical tests the usage of Viagra is efficient in about 80 percent of the cases of erectile dysfunction. Viagra makes blood influx to genitalia and it becomes the reason of erection. But the main point is that the erection will not appear independently, but only in the case of sexual excitement.
