It’s possible to get pregnant through anal sex, according to a US doctor. Brian Steixner, MD, the director of the Institute of Men’s Health at Jersey Urology Group, said that women with a rare condition called “cloaca” had conceived without having sex through vaginal penetration.

Talking to Men’s Health, Steixner recalled his “greatest story ever,” which happened when he was still training as a med student. A young woman got pregnant in a curious way. The woman was born with cloacal malformation, which meant her bladder, vagina and rectum didn’t fully develop so her intestinal, reproductive and urinary tracts came out of the same hole.

The condition could easily be fixed in hospitals, but the woman’s doctors did not do a good job in doing so when she was younger. She ended up having a “blind-ending vagina,” with her uterus connected to her rectum. This had caused the woman problem during her menstrual period.

Steixner continued that when the woman showed up in the emergency room pregnant several years later, they had determined from doing x-ray tests that she conceived from having anal sex.

“Was she going to have to poop the baby out? Steixner voiced out the question they were all asking then. “I thought that would be hilarious, but ultimately, the OBGYNs couldn’t figure out a way to effectively deliver the baby through the rectum safely. So she had a C-section.”

So while it’s very unlikely to conceive through anal sex, it is still possible. It should be noted, though, that the woman had a cloaca condition that was not properly corrected when she was younger.

“They totally lied to us in 9th grade health class,” Steixner told Men’s Health.

Cloacal malformation, according to nationwidechildrens.org, affects one in 40,000 to 50,000 newborns and occurs only in genotypic girls. It occurs early in pregnancy, about five to six weeks of conception, though its embryologic development is not clear.
