Taking a contraceptive pill makes woman brainier and more savvy, besides boosting their conversational skills.
Differences in brain structure of both the genders have been subjected to many studies, but this is the first one to look at how the hormonal contraceptive impacts brain.
The study found that the contraceptive pill preferred by 25 per cent of all 16 to 49-year-olds in Britain enhances cerebral size by three per cent, reports the Daily Mail.
Belinda Pletzer of Salzburg University, Germany, said the sex hormones in the pill were clearly having a 'tremendous effect' on the female brain.
Scientists captured high-resolution images of the brains of 14 men and 28 women, half of whom were on the pill, says the journal Brain Research.
Several areas of the brains of women on the pill were found to be larger than the brains of those of the subjects not on the contraceptive.
