It’s not easy to groom “down there,” and evidence suggests that most people do it wrong and are injuring themselves as a result, according to a new study. The conclusion that a quarter of U.S. adults are injuring themselves grooming their pubic area is based on an online survey of more than 7,500 adults.

The study found a lot of interesting results, including that 3 percent of all adults sent to the emergency room over something gone wrong in the urinary tract had to do with pubic hair grooming. Fortunately, although 26 percen tof people injured themselves by grooming, most injuries were minor cuts and burns, but 1 percent required medical attention, usually for an infection which can creep into even the smallest wound.

The study found that 67 percent of men and 85 percent of women groomed themselves. Men were slightly less likely than women to hurt themselves, but not by much at 27 to 24 percent.

“Pubic hair grooming is a widespread practice and about a quarter of people who groom reported grooming-related injuries in a national survey, according to a new article published by JAMA Dermatology,” according to a statement from JAMA Network Journals. “A better understanding of how grooming may lead to injury is warranted because of the high prevalence of pubic hair grooming. Benjamin N. Breyer, M.D., M.A.S., of the University of California, San Francisco, and coauthors conducted a web-based survey designed to be representative of the U.S. population to collect data on grooming behavior. Of the 7,570 men and women who completed the survey, 5,674 of 7,456 (76.1 percent) reported a history of grooming. Grooming-related injury was reported by 1,430 groomers, a weighted prevalence of 25.6 percent, according to the results.”
