"50 mg of sildenafil citrate is administered orally to the patient. The parameters are measured without manual or audiovisual stimulation at 60 minutes post-administration as the serum levels reach peak value by this time. Since sildenafil citrate requires a direct sexual stimulus for maximum effectiveness, an audiovisual stimulus (15 minutes of private continuous visualisation of an erotic video) is given. After that, clinical and Doppler evaluations are again performed at five-minute intervals for another 20 minutes with the patient still receiving the audiovisual stimulus."
"Semiquantitative clinical grading of an erection:"
"Duplex Doppler evaluation of erection:"
"0: flaccid"
"1: mild engorgement of the penis without adequate rigidity"
"2: partial erection allowing minimal compression"
"3: full visible erection with turgidity and complete stiffness of the penis"

"Semiquantitative clinical grading of an erection:"
"Duplex Doppler evaluation of erection:"
"Penile duplex Doppler using intracorporeal pharmacoactive agents, e.g. papaverine, has traditionally been the investigation of choice. The most troublesome side-effects have been discomfort related to intracorporeal injection, anxiety and priapism, a state of persistent and painful erection which may require treatment with blood aspiration, irrigation and injection of alpha-agonist medications."
