(By 2016, 25.6 percent of speaking or named female characters in the year’s top-grossing 100 fictional films were depicted heavily exposed (such as “chest/cleavage, midriff or high upper thigh thigh”), partially nude or nude as compared with 9.2 percent of men, according to research done by the University of Southern California’s Annenberg Inclusion Initiative.)

No way that's accurate if they're counting the exact same criteria for men. Every superhero/action movie ever made shows the male hero without his shirt. I'd also say over the last decade or two the penis has had a mainstream movie explosion from where it was NEVER shown to now it's a common and even overused comedy bit whereas boobs have gone by the wayside somewhat (compared to the 80s/90s).
