Ever since Leonardo da Vinci drew the anatomy of human copulation,
anatomists have wondered how male and female genitals interact. Schultz
et al solved the issue by performing magnetic resonance imaging on
couples during intercourse (p 1596). During intercourse in the
"missionary position" the penis is not straight, as drawn by da

During arousal the female uterus was raised and the anterior vaginal
wall lengthened but, contrary to the findings of Masters and Johnson,
the uterus was not enlarged.
