A double-blind crossover trial of clomipramine for rapid ejaculation in 15 couples

Background: The purpose of this study was to assess the sexual and psychosocial efficacy of clomipramine for rapid ejaculation. Method: Fifteen physically healthy, self-selected couples (men had a mean age of 38 years) who met six eligibility criteria and did not meet five exclusion criteria participated in a variable-length, repeated measures, randomized, double- blind, placebo-controlled crossover study with a 2-month follow-up period. Sexual and psychosocial assessments were conducted at baseline, after placebo, after 25 mg/day of clomipramine, after 50 mg/day of clomipramine, and at the 2-month follow-up point. The major outcome measures included stopwatch timing of ejaculation latencies, modified Case Western Reserve University Sexual Function Questionnaire, Symptom Checklist-90-R, Dyadic Adjustment Scale, State-Trait Anxiety Inventory, and the Harder Self-Esteem Inventory. Results: Baseline mean ejaculatory latency was 81 seconds; 25 mg/day of clomipramine increased it to 202 seconds and 50 mg/day of clomipramine to 419 seconds. This resulted in significantly greater sexual satisfaction scores for men and their partners (men, p < .001; women, p < .05), improvements in partner coital orgasmic attainment, and greater relationship and emotional satisfaction for the men. Withdrawal of the drug caused ejaculatory latencies to return to baseline. Conclusion: Clomipramine appears to be effective in significantly lengthening ejaculatory latencies and increasing sexual and relationship satisfaction. It can be a cost- effective chronic therapy for selected patients. These impressive results should not be expected in a less carefully screened population of men concerned about the timing of their orgasm during intercourse.
