What’s more impressive, having eight babies, or having two—one from each womb? Sarah Reinfelder, whom the New York Post has tastefully dubbed “Womber Woman,” did the latter, thanks to a condition called uterus didelphys, or double uterus. One in every 2,000 women has didelphys, it turns out, but most aren’t aware of it until they get pregnant, and sometimes not even then, ob-gyn Robert Zurawin tells Scientific American.
Most women with two wombs only get pregnant in one—Reinfelder’s case is one of only three recorded in the last 40 years—and if they don’t get an ultrasound early enough in the pregnancy, the womb with the child will block the other from view. Others, however, will know they have the condition from birth, because they’ll have a second cervix and vagina.
