Ever wondered what it would look like if you could see people’s insides while they were having sex? If you answered yes, you’re probably either the doctor’s who ended up putting this video together, or a possibly sexually deranged serial killer.

The ‘video’ was originally recorded in the 1960s by a dutch Doctor with too much time on his hands in Groningen.
The videos are actually created by stitching together hundreds of still MRI images to form a time-lapse.
Dr Van Andel, alongside a merry gang of live sex show (under the guise of science) enthusiasts – gynaecology Professor Willibrord Weijmar Schultz, anthropologist Ida Sabelis, radiologist, Eduard Mooyaart – used the images to form their scientific paper in 1999 with the catchy title; Magnetic Resonance Imaging of Male and Female Genitals During Coitus and Female Sexual Arousal.
The purpose was to ‘discover whether imaging of the male and female genitals during coitus was feasible.’
Otherwise known as the ‘I wonder if we can use these expensive machines to get some people in here and fuck in front of us‘ study.

The video also shows kissing, playing a horn, some babies and … ah who cares. Just show us the fucking!
