Only one couple was able to have sex without Viagra. The men had more problems with sexual performance than the women, according to the researchers, and some took sildenafil-more commonly as Viagra-in order to maintain an erection. 20 minutes after the women achieved orgasm, researchers took the final image. The women let the researchers know when they were pre-orgasm, so they could snap an image. After this, the men were asked to leave and the women instructed to bring themselves to climax. Then the men were asked to enter the room and have sex in the missionary position. The MRI scanner was positioned in a room next to a control room where researchers sat, with a curtain covering the window and the participants' modesty.įirst, the women had their pelvises scanned while lying on their backs. Once they had found enough volunteers and gained their consent, the researchers asked them to visit a university hospital in the Netherlands. Presumably in order to ensure they could fit inside the snug MRI scanner tube, the volunteers were required to have small-to average weight and height.
Researchers recruited the participants "by personal invitation," they wrote in the study, and through a local scientific TV show. Three couples had sex twice, and the single women achieved orgasm without a partner, according to the study.
