MRI porn — detailed coital anatomy pictures

Cory Doctorow 9:02 am Wed Mar 28, 2007

Dutch researchers recruited several couples (including a pair of street acrobats) to have sex in an MRI. They produced highly detailed pictures of human anatomy during coitus, and found that Da Vinci's early illustrations of coitus in cross-section made some critical mistakes.

We did not foresee that the men would have more problems with sexual performance (maintaining their erection) than the women in the scanner. All the women had a complete sexual response, but they described their orgasm as superficial. Only the first couple was able to perform coitus adequately without sildenafil (experiments 1 and 2). The reason might be that they were the only participants in the real sense: involved in the research right from the beginning because of their scientific curiosity, knowledge of the body, and artistic commitment. And as amateur street acrobats they are trained and used to performing under stress.
