"At least once a week I hear from a young woman that she thinks it’s wrong to have pubic hair, that it’s meant to be removed," said Dr. Jennifer Gunter, a specialist in pelvic pain and vulvovaginaldisorders for Kaiser Permanente Northern California.
Additionally, the Times notes that some researchers have speculated that small abrasions from grooming may aid the spread of certain sexually transmitted diseases. Though, one clinic's paper notes that the rise in waxing among both men and women coincides with a decline in the spread of pubic lice.
Ultimately, the researchers don't issue any kind of warning against grooming, but rather note that it shouldn't be done for a misguided perception that it's somehow more hygienic. "If it is something you do for you and makes you feel better, awesome," said Dr. Gunter.
