The fact that men urinate standing up seems to be a natural thing that has happened for many years, but a new study shows that standing pee affects the hygiene and environment of the house we live in more than is to do it in a sitting position.
The British research team conducted an experiment that showed how unsanitary it is for men to urinate standing up. To simulate the urination of an adult male with a urine output of 200ml, they used water mixed with fluorescent agent, then used a 6mm diameter nozzle to produce a flow of 20ml/s for 10 seconds. Finally, they shined an ultraviolet light to see how the water would splash when urinating standing. The flow of urine when men walk is an uneven torsion stream.
Here are the main contents of the video:
69% of men choose to stand while urinating instead of sitting. Two-thirds of men when urinating into the toilet always aim at the places they think are the most limited to splashing urine.
31% of men pee standing against the inner wall of the toilet because they think this is the best position to limit the splash of urine. But in fact, the urine that falls into this position is true to reduce large water particles but creates many tiny particles that are invisible to the eye.
So one-third of men are urinating against the wall of the toilet with the goal of reducing splashing, but they’re actually creating more water splashing around.
Many men think they pee very neatly, but that’s not the case at all.
Urine splattered out, stuck to the toilet paper rolls.
Even urine sticks to the wall.
The team also tried various ways to see which patterns of men pee were least likely to splash around.
29% of men urinated directly into the water in the tub. Although this type of urination produces the largest number of drops, these splashes mostly stay in the tub, rarely splashing out.
Only 2% of men urinate in front of the toilet. And this is the location that generates the least amount of splashing water.

In Germany, mothers often teach their sons to sit down to urinate from an early age because this is considered a civilized and encouraging behavior. According to the results of a survey in 2007, 49% of married men in Japan sit to urinate, an increase of 15% from 1999. The Taiwanese government has also encouraged this practice since 2012.
