The Story of Menstruation is a 1946 10-minute American animated film produced by Walt Disney Productions. It was commissioned by the International Cello-Cotton Company (now Kimberly-Clark) and was shown in a non-theatrical release to approximately 105 million American students in health education classes. In 2015, it was selected for preservation in the National Film Registry.
It was part of a 1945 to 1951 series of films that Disney produced for American schools. Gynecologist Mason Hohn was hired as a consultant to ensure that the film was scientifically accurate. Hohn was hired to increase the likelihood that school doctors and nurses would allow the film to be shown. Hohn’s involvement led to a stronger emphasis on biology than other marketing by ICCC. The Story of Menstruation increased its reputation when it received the Good Housekeeping Seal of Approval.
It was one of the first commercially sponsored films to be distributed to high schools. It was distributed with a booklet for teachers and students called Very Personally Yours that featured advertising of the Kotex brand of products, and discouraged the use of tampons, where the market was dominated by the Tampax brand of tampons from Tampax Inc.
In 2015, the United States Library of Congress selected the film for preservation in the National Film Registry, finding it “culturally, historically, or aesthetically significant.”
