Very few data are available on the effect of pelvic floor muscle training on sexual function in incontinent women. The authors used the Female Sexual Function Index to assess the effect of pelvic floor muscle training on female sexual function. Participants included women with stress urinary incontinence, without overactive bladder symptoms, who completed a 3-month pelvic floor muscle training. All patients completed the Female Sexual Function Index and the International Consultation on Incontinence Questionnaire-Short Form at baseline and at the 3-month follow-up. Thirty-four patients completed all of the questionnaires; 64.7% patients were referred with stress urinary incontinence without sexual disorders, while 35.3% complained of stress urinary incontinence and sexual symptoms. The International Consultation on Incontinence Questionnaire-Short Form score significantly decreased after 3 months of pelvic floor muscle training (p =.01). The Female Sexual Function Index score significantly improved after pelvic floor muscle training even in women with sexual disorders (12.5 ± 9.5 vs. 29.7 ± 3.7; p <.001). This study showed that pelvic floor muscle training may improve female sexual function in women with pure stress urinary incontinence.
