Sex in MRI?! #shorts

Scientists convinced couples to have intimacy inside an MRI machine, and what they discovered changed medicine forever. For 500 years, we relied on Leonardo da Vinci's sketches showing the anatomy as a straight tunnel. Doctors never actually checked if that was accurate until 1991. When Dutch researchers finally got brave volunteers into the MRI scanner (imagine trying to stay still in a cramped, clanging tube while three male researchers give you instructions), the images proved Leonardo completely wrong. The actual angle is more like a boomerang at 120 degrees. About a third of what's happening is completely hidden behind the pubic bone. But here's what really surprised me: in every scan, women's bladders rapidly filled during arousal, even if they'd just emptied them. Scientists believe this is evolution's way of protecting against UTIs by prompting urination after intimacy. This is why evidence matters more than assumptions. Save this if you love fascinating medical history. #shorts
