The complementary role of different neurophysiological methods to demonstrate organicity in male with premature ejaculation and erectile dysfunction.

Erectile dysfunction and premature ejaculation are the most common male sexual disorders. Generally, it is considered that erectile dysfunction is related to organic factors whilst premature ejaculation is related to psychological factors. A detailed history along with physical examination such as using penile doppler, penile tumesans and ultrasonography are insufficient for differential diagnosis in 15-20% of cases. Therefore the role of neurophysiological techniques are important. In this study urological and biochemical investigations were used in conjunction with other neurophysiological methods. According to our results, using a neurophysiological test study on its own was ineffective. As a conclusion our study has shown that neurophysiological methods are important differential diagnosis of revealing suspicious organicity--generally believed to be due to psychological factors- in male sexual disorders
