The Woman Who Gave Birth to Identical Triplets, Two of Them Conjoined
Sylvia Hernandez gave birth to identical triplet girls this month in Texas, which the Washington Post reports, happens in one in 50 million births. Even more rare: Two of the triplets are conjoined.
Prince points out that conjoined babies only occur with identical multiples. He says it implies that there was an earlier split of the egg and then a later split that didn’t fully separate. But, as he says, this is a rarity on top of another rarity.
The Woman Who Had Two Wombs—and Got Pregnant with a Set of Twins in One and Another Baby in the Other
British woman Hannah Kersey gave birth to twins and another baby at the same time—and carried them in two different wombs. The 23-year-old is believed to be the first woman in the world with uterus didelphys (i.e., having two wombs) to give birth to triplets, BBC News reports.
Prince calls this “extremely rare,” especially since it can be difficult for women with uterus didelphys to carry twins to full term in the first place.
Twins run in your family? Don’t freak out: Klugman stresses that all of these situations are extremely unlikely.
