The pill can change the shape of your brain, new study suggests New research suggests that the synthetic steroids delivered by the female contraceptive pill can shrink certain regions of the female brain and could also be altering their function. Neuroscientists from the University of California, Los Angeles in the US took brain scans of 90 women who were either currently using the pill or not, and found that two key brain regions were thinner in pill users - the lateral orbitofrontal cortex and the posterior cingulate cortex. These two regions are involved in emotion regulation, decision-making and reward response, and the researchers believe that their findings could help explain why some women become anxious or depressed when taking the contraceptive pill. "Some women experience negative emotional side effects from taking oral contraceptive pills, although the scientific findings investigating that have been mixed," lead author of the study, Nicole Petersen, told The Huffington Post. But don't panic just yet.
