MRI of coitus and semi-identical twins

Just two interesting articles from the past day. After so many serious posts, this one is about real popular medicine. I hope you’ll like it.

What started as artistic and scientific curiosity has now been realised. We have shown that magnetic resonance images of the female sexual response and the male and female genitals during coitus are feasible and beautiful; that the penis during intercourse in the “missionary position” has the shape of a boomerang and not of an S as drawn by Dickinson; and that, in contrast to the findings of Masters and Johnson, there was no evidence of an increase in the volume of the uterus during sexual arousal.

It’s really unbelievable what people are writing about these days.

Researchers have discovered a pair of twins who are identical through their mother’s side, but share only half their genes on their father’s side… Genetic tests revealed that each twin contained some ‘female’ cells with two X chromosomes, and some ‘male’ cells with an X and a Y. The proportion of each type varies from tissue to tissue in each twin, the researchers report in Human Genetics.
