The snake whose bite can send you back through puberty

Illustration for article titled The snake whose bite can send you back through puberty

We've gotten used to animals having strange powers — like using sound to create 'vision,' seeing more colors than we do, and sensing polarized light or the magnetic field of the earth. But did you know that some animals have 'powers' over human physiology? The Russell's Pit Viper can use its venom to send you back through puberty.


The Russell's Pit Viper spends its days crawling through Southeast Asia, eating small rodents, and giving people yet another reason to fear snakes. Not because they kill thousands of people every year. That's unpleasant, but we already knew that about most snake bites. No, this is a snake that screws with you even if you survive the bite. The mechanism of its particular brand of lasting torment lies in the effects of the bite itself. Often the bite destroys the kidneys, with kidney failure often claiming the lives of people who survive the initial bite, and hemorrhaging occurs throughout the body. 'Throughout the body' includes the pituitary gland.

Although the pituitary gland is the star in puberty, it continues to play a supporting role throughout a person's life. Damage or sufficient amount of blood loss can cause the gland to cease production of necessary hormones. The extent of damage of any snakebite depends on several factors, including how fast an antivenin is applied, but Russell's Viper victims often have significant damage to the gland. In a study published in The Lancet, about twenty-nine percent of patients who recovered from Russell's Viper venom had signs of hypopituitarism or Sheehan's Syndrome. Both conditions have unremarkable symptoms, like a constant feeling of cold and an unusual amount of fatigue. What distinguishes them is a sort of reverse-puberty in adults. They lose their sex drive. They lose fertility. They lose their body hair, especially pubic hair. Men lose facial hair and muscles. Women lose curves as the condition causes them to lose weight. Some doctors even report loss of mental faculties as the condition progresses.

Doctors have success in treating viper victims with replacement hormones, but that doesn't take away this odd, and entirely scientific power. In science fiction and fantasy fiction, people often run across creatures that can do crazy things like eating souls, mesmerizing minds, and animating dead bodies. It's strange to think that, across our own world, crawl creatures with the ability to send our bodies, in everything but height, back to childhood with a bite. If you read that in a science fiction story, would you ever believe it could happen?

I'm sorry but I have to get on my soap box for just a sec...ahem*

In response to your statement regarding snake and their bites killing people in the second paragraph, "That's unpleasant, but we already knew that about most snake bites. " As a conservationist, nature boy, amateur herpetologist and all-around good guy, I must protest the implication in that sentence. Most snakes are not venomous and most snake bites are hence harmless. In fact, most snake bites are a result of unnecessary contact, agitation or improper (and needless) handling. I hate that snakes get such a bad rap, and let's face it, it's mostly because of their appearance that they've been demonized in various cultures and histories...also because we have an evolutionary response to be creeped out by potentially harmful forms (spiders, snakes, bright red berries). Anywho, my point is to give snakes a chance, folks. They aren't so bad and they are damn useful. :)
