A total of 4 studies (n=293) compared menstrual cups to usual products (tampons and/or pads) for the outcome of leakage. In 3 studies, leakage with menstrual cups was reported as similar to that of usual products, while 1 study reported less leakage with menstrual cups. There are 7 studies (n=934) using currently available menstrual cups in which leakage is reported as a proportion of users. The proportion ranged from 2% to 12%.
