“The presentation of menstruation on screen is an overwhelmingly negative one,” she said.
The analysis included jokes, plotlines and references from popular TV shows such as The Big Bang Theory, Mad Men, Friends and Grey’s Anatomy, and blockbuster films like Annie Hall, Anchorman and Monty Python’s The Meaning of Life.
“The regularity, normalcy and uneventfulness of real life menstruation is rarely portrayed on screen. Instead, it’s treated as traumatic, embarrassing, distressing, offensive, comedic or thoroughly catastrophic,” she said.
“There are numerous portrayals where menstruation is considered as evil, disgusting and as the root of all female evil.”
Dr Rosewarne said these negative representations affected how women approached their own experiences.
“Girls in real life are viewing menstruation as a hassle, women are happily filling prescriptions to make it go away, men are mocking it, loathing it and rarely understanding it,” she said.
“On screen presentations likely have some complicity.”‘
The research identified the representation of menstruation in Carrie (1976) as perhaps the most traumatizing.
“The fusion of a naked girl, shower stream, screaming and blood harked back to cinema’s most famous shower horror scene from Psycho. Even though the audience presumably recognized Carrie was only menstruating, the character’s terror was contagious.”
