Men really do have sex on the brain

Men apparently think about sex every few seconds and new research suggests it’s all down to extra brain cells. A study into the subject determined that these two additional cells motivate males to seek out sex, making it a priority over anything else.

The data was collected by scientists from The University College London, who studied tiny worms, which have similar biology to humans. It seems men really do have sex on the brain after the pair of cells – previously referred to as MCMs or mystery cells of the male – were found to have a powerful impact on the sex drive of a man.

The study focused on C. elegans, soil-dwelling worms measuring just 1mm long, which come in two sexes – male and hermaphrodite (an organism boasting reproductive organs normally associated with both male and female sexes). Previous research showed that the male worms had an additional two brain cells when compared to the hermaphrodites and this latest data has shed light on how they influence behaviour.

“In the broader picture, it gets at this question of how do men and women think and behave differently,” UCL researcher Dr Richard Poole explained. “We always wonder, do we have different learning aptitudes or is it social, and in this case, it happens to be genetic.”

Scientists believe the cells allow males to process information differently and “prioritise sex in future situations”.

During the study, the worms learned to link starvation with saltiness, so when they were placed on a plate with high concentrations of the mineral, they moved away. Both sexes of worm adopted this behaviour. However, when the worms were trained to associate saltiness with starvation and sex, the males headed towards the mineral, while the hermaphrodites continued to avoid the substance. Male worms who had their MCMS removed also displayed a dislike for the salt, even when it was associated with sex.
