If you are considering trimming or even shaving your pubic hair, beware: a new study claims that people injure themselves doing this a lot more than you might think. An online survey of more than 7,500 U.S. adults found that a quarter of the time, the grooming resulted in cuts, burns, and even infections.

Another study found that 3 percen tof all adults who had been to the emergency room for a urinary injury were there because of pubic hair grooming. In addition, a lot of people seem to do it, with 67 percent of men and 85 percent of women practicing some sort of grooming.

But 26 percent of them injured themselves by doing it. Women were slightly more likely than men (27 to 24 percent). Fortunately, most of the injuries aren’t severe, with just 1 percent of them requiring medical attention. But even a small open wound can result in an infection, and you don’t want that down there.

“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,” the statement from JAMA Network Journals reads. “A better understanding of how grooming may lead to injury is warranted because of the high prevalence of pubic hair grooming.”
