The fresh volunteers was in fact shown the device regarding the a couple of bedroom, and personal and you will gynaecological histories was in fact removed. The new fresh techniques are explained, and all investigators leftover the new imaging space. After a preliminary picture for position the real pelvis of your lady was drawn, the original visualize is removed together with her lying on her straight back (visualize 1). Then your men is actually questioned so you’re able to go on the tube and you may start one on one coitus on advanced standing (visualize 2).

It provided poor quality images with quite a few way artefacts. Inside 1996 the latest Siemens Attention 1.5 Tesla magnet system turned readily available and you may considering the opportunity to remain all of our seek out clear photo. Half a dozen partners succeeded when you look at the partial, even though perhaps not done, penetration (experiments step 3 and you will seven-11). Into the 1998 sildenafil (Viagra) turned into available in the netherlands The 2 people for the experiments nine and you can 11 was basically greeting to help you repeat the process an hour immediately following the guy got taken one twenty-five mg pill away from sildenafil.
