Abstract

A classification of premature ejaculation must distinguish between hyper-orgasmic or hypo-orgasmic, between situational or global; furthermore, it must define whether it occurs during vaginal penetration only or also in masturbation, and must study its latency periods and its relationships to the erectile dysfunction, with which it is often associated. Tests with local anesthetics, biothesiometry and penile vibrotactile stimulation, integrated with a thorough study of the general and psycho-sexual history, provide a good diagnostic classification that makes the therapeutic approach appropriate.

Efficacy of sildenafil citrate in treatment of erectile dysfunction: impact of associated premature ejaculation and low desire.

OBJECTIVES: To assess the effect of premature ejaculation (PE) and low desire on the efficacy and satisfaction rate of sildenafil in the treatment of erectile dysfunction (ED). METHODS: A total of 586 male patients with ED in association with and without PE or low desire were enrolled in this study. Patients were screened for ED using the International Index for Erectile Function. All patients were also screened for PE and low desire. We compared the responses to the erectile function domain, questions 3 and 4, before and after sildenafil in patients with and without PE or low desire. Overall satisfaction and global efficacy question responses were also assessed in all patients. RESULTS: The mean age +/- SD was 58 +/- 6.4 years. Significant associations were found between the increased duration and severity of ED and the decreased rate of overall satisfaction. Before sildenafil administration, significant differences were found in the erectile function domain, Q3 and Q4 between patients with and without PE or low desire. After sildenafil administration, no significant differences were found in those assessment variables and the presence or absence of PE and low desire. No significant differences were found between the global efficacy question response and the overall satisfaction rate between patients with and without PE or low desire. CONCLUSIONS: The efficacy of sildenafil was negatively affected by an increased duration and severity of ED; however, global efficacy and overall patient satisfaction were not attenuated by PE or low desire.
