Dear user, Thank you for writing to HCM. I can understand your concern regarding urine incontinence. Masturbation is a part of normal sexual activity and it does not have any hazard. It does NOT cause urine incontinence. None of your medications likely to cause urine incontinence or urge incontinence (leaking). Urinary tract infections or lesions of spinal cord, inflammation of prostate, urinary obstruction are common causes of urine incontinence. You should consult a physician for the same. Wish you good health and recovery.
