[Dysfunction of penile erection].

Nearly 250 men with erectile dysfunction examined during the past 3 years period. Beside the examination technique development the author emphasizes on the importance of the medical history and the psychological exploration. The examinations are indicated after the analysis of the history and after the positive result of the noninvasive examination the invasive one is only indicated. Intracavernous injection of the vasoactive drugs remains important part of the diagnosis, but the combination with the Doppler examination gives more information about the origin of the dysfunction.
