Leonardo also did an anatomical drawing of human intercourse:

This illustration of the anatomy of human sexual intercourse has been shown to be incorrect by MRI scans:

‘Midsagittal image of the anatomy of sexual intercourse (experiment 12). P=penis, Ur=urethra, Pe=perineum, U=uterus, S=symphysis, B=bladder, I=intestine, L5=lumbar 5, Sc=scrotum’

From: ‘Magnetic resonance imaging of male and female genitals during coitus and female sexual arousal’ BMJ 1999;319:1596
