Can Kidney stones lead to weak erections? I m a healthy enough 20 year old male who s had no problems with the little guy saluting me before, but I ve noticed recently it s becoming a nuisance. I didn t think anything of it at the time, but the doctor asked if I d noticed anything going on or weakening of my erections, but now it s got me thinking twice. I ve got a stone in each kidney they say, and they basically told me good luck and to wait it out hoping for the best. Any help is greatly appreciated!
