Pubic hair grooming injuries jumped five-fold between 2002 and 2010, according to a recent analysis of ER visits by scientists at the University of California, San Francisco. The cringe-inducing reports increased most at the end of the time frame, with an estimated 2,500 grooming mishaps a year by 2010.

And those are just the cuts, burns, gashes, rashes and other unpleasant outcomes that required emergency medical attention, said Dr. Allison Glass, a clinical researcher at UCSF. Those figures are likely a vast underestimate of the true injuries, and a reminder, among other things, of the need for extra care when wielding razors or hot wax.
