There are a number of articles that combine the statement that men should sit while peeing for hygiene reasons* and that sitting whilst peeing reduces prostate issues.
The problem is that I cannot seem to find the original or a reference to any actual research behind the claim. I would like to know if this study really exists and then is it enough to really base behavior on.
Medical research reported in Sweden’s Folket newspaper said that sitting might mean reduced prostate cancer risk and be better for you in the bedroom. That’s because the bladder empties more efficiently when men take a seat while urinating, and this improved bladder release supposedly decreases prostate problems and allows for a longer and healthier sex life.
