Summary
Time-limited group psychotherapy, with or without sildenafil, effectively treats psychogenic erectile dysfunction (ED). Psychotherapy alone or combined with medication yielded better erectile function improvement than medication only.
Area of Science:
- Psychiatry
- Urology
- Psychology
Background:
- Psychogenic erectile dysfunction (ED) significantly impacts men's quality of life.
- Treatment options for psychogenic ED include pharmacotherapy and psychotherapy, but comparative effectiveness is debated.
Purpose of the Study:
- To compare the effectiveness of time-limited theme-based group psychotherapy, sildenafil citrate, and a combination of both for treating psychogenic ED.
Main Methods:
- 30 patients with psychogenic ED were randomized into three groups: psychotherapy + sildenafil (Group I), sildenafil only (Group II), and psychotherapy only (Group III).
- The International Index of Erectile Function (IIEF) questionnaire was administered at baseline, immediately post-treatment, and 3 months post-treatment.
- Data were analyzed using ANOVA and Bonferroni tests, with Cochran's Q-test for symptom remission analysis.
Main Results:
- Both psychotherapy groups (I and III) showed statistically significant improvements in erectile function scores compared to the sildenafil-only group (Group II).
- Group III (psychotherapy only) demonstrated significantly higher mean IIEF scores than Group II immediately post-treatment (p=0.033) and at 3 months (p=0.049).
- Significant improvements from baseline were observed in Group I (p=0.0009) and Group III (p=0.0002), but not in Group II (p=0.135).
Conclusions:
- Time-limited theme-based group psychotherapy is an effective standalone treatment for psychogenic ED.
- Psychotherapy, whether combined with sildenafil or used alone, leads to superior outcomes in erectile function compared to sildenafil monotherapy for psychogenic ED.
