Jessica Allen, who was a surrogate mother for a Chinese couple, was pregnant for the second time with her partner, writes Science Alert.

In exchange for $30,000, Allen received in vitro fertilization treatment with one of the Chinese couple’s embryos that could not otherwise conceive a child.

At first, the pregnancy was carried out in normal parameters, but during the sixth week routine screening, the doctors noticed that the woman was pregnant with two fetuses.

“The chances of an embryo being split are very small, but it happens”, the woman said.

Then everyone thought the two were identical twins without anyone considering the phenomenon of superfattery.

Superfatty is extremely rare in humans – when a woman continues ovulating while pregnant, being able to give birth to a second child that grows simultaneously with the first fetus.

Although it is a rare phenomenon in humans, being about 10 cases in the literature, it is common in the animal world, being observed in rodents, sheep, horses and kangaroos.

In the case of Allen and his partner, they managed to conceive the second child even if they used contraceptive methods. Allen gave birth to the two by cesarean, and only then doctors and parents noticed a strange thing. “I saw one was smaller than the other. They cannot be identical twins.”

After a few weeks, DNA tests confirmed that one of the children was of Chinese couple and the other was the baby of the American couple.

After some legal problems, the boy named Malachi came home to biological parents. So the story had a happy ending.
