By our count, Maricica Tescu's delivery defied the odds not once, but four times.
First, Tescu herself was born with an abnormality called uterus didelphys. This condition results when the two tubes that normally merge into a single uterus remain separate, creating two individual wombs. It affects roughly 1 in 2,000 women worldwide. Granted, that's a lot of women. But Tescu conceived a child simultaneously in each uterus, one of only about 100 such occurrences on record [source: Chitale].
Second, both of Tescu's children were born alive and survived. Double uteruses rarely maintain one pregnancy, let alone two. Tescu's first baby arrived in December 2004, two months early. He was placed in the intensive care unit due to difficulty breathing. That's a common hazard of premature birth, the lungs being the last organ to develop prenatally. But he fully recovered in the hands of the team at Cuza-Voda Hospital in Tescu's hometown of Iasi, Romania.
Third, in uterus didelphys, premature labor in one uterus often triggers labor in the other -- but this didn't happen to Tescu. Doctors were able to let the other boy develop in the womb.
Fourth, the second baby was delivered full term. Doctors performed a cesarean section 59 days later in early February, 2005. By some calculations, the odds of a twin conceived in a double uterus being carried to full term are 1 in 5 million [sources: BBC News; Chitale].
Our next story shows that the saying "good things come in small packages" can be carried too far.
