Performance
Thirteen studies had been performed having 7 partners (three lovers performed a few tests each) and you may three solitary lady. The new desk shows years, weight/level directory, parity, type of birth-control, females orgasm (yes/no), and depth out-of entrance (limited or complete).

This new Philips step 1.5 Tesla magnetic program at that time expected a comparatively a lot of time acquisition time (52 mere seconds) together with a fairly terrible laws:audio proportion. Which gave poor images with many way artefacts. Inside the 1996 the brand new Siemens Eyes step one.5 Tesla magnet program became readily available and offered the ability to continue all of our identify sharp photos. Half dozen people been successful inside partial, even though perhaps not done, penetration (studies step three and you can seven-11). From inside the 1998 sildenafil (Viagra) became for sale in holland. The two partners in tests 9 and eleven were enjoy so you can repeat the process an hour or so after the boy had taken one to 25 milligrams pill out of sildenafil. It been successful having done entrance you to survived for enough time (a dozen moments) to possess evident images you need to take (studies twelve and you may 13).

The root of your own cock (1/step 3 of your duration) together with upright pendulous muscles (2/step three of the duration) try apparent.

The new volunteers was in fact found the device from the one or two bed room, and private and you will gynaecological histories had been drawn. The new experimental techniques was informed me, and all of investigators leftover the fresh imaging place.
