Science Vs

Everyone’s got a myth or two about birth control they want cleared up. Like... is 'pulling out' AKA withdrawal really such a bad idea? Does the pill change your brain? Are IUDs safe? And why isn’t there a pill for men, already?! We ask gynecologist Dr. Amita Murthy, neuroendocrinologist Dr. Nicole Petersen, men’s health researcher Prof. Robert McLachlan and a whole roomful of experts on sex -- teenagers.

UPDATE 05/12/17: We have updated this episode to further emphasize that the pre-cum studies are only very small. Use withdrawal at your own peril!
