Performance

13 tests have been performed with seven lovers (around three partners did a couple of tests for every) and you can around three single women. The dining table suggests many years, weight/level directory, parity, particular birth prevention, female climax (yes/no), therefore the breadth out-of penetration (partial or complete). Zero female stated having good “g-spot” otherwise promoting female ejaculation throughout the climax.

The newest Philips step 1.5 Tesla magnetic system during the time called for a relatively much time order go out (52 moments) together with a somewhat bad signal:audio ratio. It offered low-quality photographs with many different movement artefacts. For the 1996 the brand new Siemens Eyes step one.5 Tesla magnetic program turned readily available and you may offered the opportunity to continue our very own identify clear photographs. Half dozen people succeeded in the limited, whether or not maybe not done, entrance (studies 3 and you will eight-11). In 1998 sildenafil (Viagra) turned found in holland. The two partners inside tests 9 and you will eleven have been greet so you’re able to repeat the procedure an hour or so following boy had removed one twenty-five mg pill out of sildenafil. It succeeded that have over entrance you to survived long enough (a dozen seconds) to own evident photo you need to take (studies several and thirteen).

The underlying of the penis (1/step three of your duration) and also the erect pendulous muscles (2/step 3 of your own size) are noticeable. The brand new pendulous part of the upright penis moved up from the a keen position of approximately 120° toward root of the knob, and almost synchronous on the woman’s spine. In most brand new experiments this technology occurred in so it coital standing and you may wasn’t pertaining to the fresh breadth away from entrance. In over penetration your penis filled up the latest anterior fornix (studies step 1, dos, and you may 13) and/or posterior fornix (try a dozen; fig ? figstep 3). step three ). During the intromission the fresh new pubic bones of your men plus the women didn’t strategy both directly: the feminine pubic bone stayed regarding cuatro cm cranial to that particular of your own male. This new womb grew up of the dos.4 cm.

This new volunteers have been shown the equipment from the a couple of rooms, and personal and you can gynaecological histories had been taken. The latest experimental process are explained, as well as detectives remaining the latest imaging room. Immediately after an initial photo having placement the true hips of the girl try pulled, the first visualize was removed together lying on her straight back (image 1). Then your men try questioned to help you ascend towards tubing and start one on one coitus from the superior position (picture 2).
