Just when you thought convincing your girlfriend that sliding it into her back door was safer, something like this comes along and spoils your "good fortune." That's because, according to Indy 100, some lady just became the first person on planet earth to get pregnant from anal sex.
Dr. Brian Steixner MD, Director of the Institute of Men’s Health at Jersey Urology Group in Atlantic City, has explained that one of his patients had a condition termed cloaca. It occurs in the womb when a female foetus’ bladder, vagina and rectum do not develop normally and instead intestinal, urinal and reproductive functions are all performed from the same orifice.
The woman was referred for surgery to correct this when she was younger as is standard treatment for cloaca cases. However the surgery was botched, resulting in her uterus being wrongly connected to her rectum.
Years later, she became pregnant, to the surprise of Dr. Steixner and his colleagues. He told Men’s Health: “We knew about her condition, and we had followed her for a decade. After doing a whole bunch of X-rays, we determined that she got pregnant from having anal sex.”
So, uh, this is the most WTF news I've written about in a long time.
Since you've probably already thought about it—because you're sick and juvenile like we are—no, just because the baby was conceived through anal sex does not mean that the woman pooped it out, instead having a C-section. That occurred because, according to Dr. Steixner, "“The obgyns couldn’t figure out a way to effectively deliver the baby through the rectum safely."
As for the chances of something like this happening to you, well, Steixner says that this incident was a "one in a billion and the rarest of the rare," so you shouldn't have to worry about it unless you, literally, have the worst luck ever.
