Aim: This study was planned to determine the effect of urinary leakage on sexual function during sexual intercourse. Methods: The study group included 32 incontinent women who had urinary leakage during sexual intercourse and the control group consisted of 60 women with no such problem. The Sexual History Form of Schover and Jensen was completed in face-to-face interviews in a private room. Results: When compared with the women without any problem, the women with urinary incontinence were 4.7 times less satisfied with their sexual life and their partners had ejaculation without full erection 3.1 times more. In order to cope with the problem of urinary incontinence during coitus the women themselves adopted several methods. Trying to keep their partners unaware of the problem and deferring the intercourse were among the most frequently adopted methods. 43.7% of the study group indicated that this problem affected their sex life. Conclusions: The results of this study support the view that urinary leakage during coitus affects women’s sex life adversely.
