Introduction/objective: Sexual dysfunctions (SD) are highly prevalent in the male population and should be investigated as a routine. The Male Sexual Quotient (MSQ) is a validated self-assessment instrument that considers several domains of male sexual behavior. This study aimed to evaluate the MSQ score of a large sample of ED patients, before and after sildenafil treatment.
Methods: Heterosexual ED patients with stable relationships participated in the study, conducted in more than two hundred Brazilian urological clinics. Patients’ most frequent comorbidities were hypertension, diabetes mellitus, benign prostatic hyperplasia and dyslipidemia. In the first visit, they responded to the Male Sexual Quotient (MSQ) questionnaire and were instructed to take an initial dose of 50 mg of sildenafil before sexual intercourse, once or twice a week. Patients were followed during a 6-week period, after which they were re-evaluated at final visit and asked to answer the questionnaire again. Differences between the MSQ scores, before and after 6 weeks sildenafil administration, were compared by Student’s t test.
Results: 1293 patients were included, from which 1089 constituted the sample, with average age of 53.2 and 2.2 sexual intercourses/week. The average use of sildenafil was 10.4 tablets/patient along the study. The initial MSQ score corresponded to 46.3 ± 14.3 and the final MSQ score to 74.8 ± 15.6 (p<0.001). At the end of the study, 38,3% of patients scored “excellent” and 44,3% scored “good”, due to statistically significant improvement in the responses of all MSQ questions, specially those that measure quality of erection (118.8%), ejaculation control (83.8%) and sexual satisfaction (81.0%).
Conclusions: MSQ questionnaire detected clinical improvement brought on by SD treatment. Due to its utility in the general evaluation of male sexual function/satisfaction, the MSQ may be useful in studies about male sexual domains and their respective therapeutic interventions.
