Different studies have found that masturbation is frequent in humans. Alfred Kinsey's 1950s studies on US population have shown that 92% of men and 62% of women have masturbated during their lifespan. Similar results have been found in a 2007 British national probability survey. It was found that, between individuals aged 16 to 44, 95% of men and 71% of women masturbated at some point in their lives. 73% of men and 37% of women reported masturbating in the four weeks before their interview, while 53% of men and 18% of women reported masturbating in the previous seven days.
