Men should urinate in a seated position rather than standing for reasons of hygiene and health.

This recommendation is based on research, notably a meta-analysis published in PLoS ONE (2014), which suggests that for men suffering from lower urinary tract symptoms or benign prostatic hyperplasia, the seated position promotes better bladder emptying and lower pressure. Research indicates that this posture allows for more effective contraction of the abdominal muscles and optimal relaxation of the pelvic floor, thereby facilitating urinary flow. Outside of these clinical contexts, the argument is often focused on domestic hygiene to limit splashing. However, there is no scientific consensus mandating this practice for young, healthy men without urinary disorders. The idea is therefore scientifically grounded for certain specific populations, but sometimes extrapolated to the entire male population without strict physiological necessity. The approach remains relevant from the perspective of daily comfort and cleanliness.
