[Personality and psychological characteristics of premature ejaculation patients].

OBJECTIVE: To investigate the personality and psychological characteristics of premature ejaculation (PE) patients and the correlation between them two. METHODS: Using Eysenck Personality Questionnaire (EPQ) and Symptom Checklist 90 (SCL-90), we conducted an investigation among 94 PE patients seeking medical advice in Drum Tower Hospital from October 2018 to February 2019. RESULTS: The neuroticism score of the PE patients on EPQ was significantly higher than the national norm of adult males (t = 12.010, P < 0.01), and so was their introversion-extroversion score (t = 2.557, P < 0.05), while their concealment score was markedly lower (t = －8.736, P < 0.01). The coercion score of the patients on SCL-90 was remarkably higher than the national norm of adult males (t = 2.787, P < 0.01), and so were their psychosis score (t = 3.944, P < 0.01) and anxiety score (t = 2.512, P < 0.05). There was a significant correlation between the EPQ and SCL-90 scores of the patients. Psychoticism was found highly positively correlated with terror (r = 0.455, P < 0.01), interpersonal relationship (r = 0.295, P < 0.01), hostility (r = 0.375, P < 0.01), psychosis (r = 0.363, P < 0.01), compulsion (r = 0.284, P < 0.01), depression (r = 0.294, P < 0.01), paranoia (r = 0.336, P < 0.01), somatization (r = 0.400, P < 0.01) and anxiety (r = 0.358, P < 0.01), and so was neuroticism with terror (r = 0.466, P < 0.01), interpersonal relationship (r = 0.611, P < 0.01), hostility (r = 0.509, P < 0.01), psychosis (r = 0.593, P < 0.01), compulsion (r = 0.573, P < 0.01), depression (r = 0.560, P < 0.01), paranoia (r = 0.550, P < 0.01), somatization (r = 0.465, P < 0.01) and anxiety (r = 0.572, P < 0.01). Introversion-extroversion, however, was highly negatively correlated with interpersonal relationship (r = －0.226, P < 0.05) and depression (r = －0.228, P < 0.05), and so was concealment with terror (r= － 0.351, P < 0.01), interpersonal relationship (r = －0.433, P < 0.01), hostility (r = －0.347, P < 0.01), psychosis (r = －0.427, P < 0.01), compulsion (r = －0.345, P < 0.01), depression (r = －0.379, P < 0.01) , paranoia (r = －0.393, P < 0.01), somatization (r = －0.204, P < 0.05) and anxiety (r =－0.237, P < 0.05). CONCLUSIONS: The personality and psychological status of PE patients are different from those of normal males, and some personality characteristics of the patients are correlated with their psychological status, especially with high neuroticism.

The application of intraoperative neurophysiological monitoring in selective dorsal neurotomy for primary premature ejaculation: a prospective single-center study.

Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.
