Oh, this story is making the rounds again:
Brazilian Bikini Waxes Make Crab Lice Endangered Species
Pubic lice, the crab-shaped insects that have dwelled in human groins since the beginning of history, are disappearing. Doctors say bikini waxing may be the reason. Waning infestations of the bloodsuckers have been linked by doctors to pubic depilation
Like the last time, this story is getting a lot of popular press. However, what is presented is a lot of anecdotal evidence—stories without a lot of actual data.
I will say that the evidence is much better than the last time this story made the rounds, and this is a far better written story. However, please note that conspicuously sprinkled through the article are links to a bunch of major grooming appliance and beauty product companies. Gosh, I can’t imagine why they might have a vested interest in promoting the idea that waxing and shaving your short and curlies might prevent pubic lice.
Here’s an important part of the story:
“Incidence data aren’t kept by the World Health Organization in Geneva because the gray, six-legged, millimeter-long louse doesn’t transmit disease, and national authorities such as the Centers for Disease Control and Prevention in Atlanta and U.K.’s Health Protection Agency don’t collect the information.”
We only have anecdotal data from local health centers, such as the ones interviewed in the story. And:
“Historically, it’s been very difficult to get incidence data on pubic lice simply because people don’t like to report it,” said Richard Russell, director of medical entomology at Sydney’s Westmead Hospital. “In over 40 years, I could count on two hands the number of people who had brought pubic lice in for identification and admitted to knowing what they were.”
If you want to start trimming your shrubbery, go right ahead. But don’t do it because you think it will protect yourself from pubic lice, do it because you want to (for some inexplicable reason that I don’t understand myself, frankly.) You should also be aware that injuries from genital grooming are on the rise, and it is not without risk. This is rightly pointed out in the article, for which I again give them props.
The article ends with this quote from a scientist. Emphasis mine in this quote:
“The life cycle of the female pubic louse ends if it’s unable to find a suitable place to lay eggs, Russell said, making it plausible that pubic hair removal is reducing populations of the insect. “It makes sense from the point of the view of the biology of the beast, but how you’d ever find out, I don’t know,” Russell said in a telephone interview. “
We probably won’t ever really know the answer question of habitat destruction for the crab louse. This is ‘news’ only because crotch crickets are interesting because of the pastures they graze in. (Which, of course, is exactly why -I- wrote about them!)
But don’t forget that just because a few people in the US and Down Under (snorf!) remove their body hair, the vast majority of people have intact lady gardens. This is an attention-getting article, not news.
