As you already guessed it yourself, we would not write an entire article if the answer to this question were negative. As you know, cats in a litter may have all kittens from different cats - for them this is the norm, but it turns out that people also have something similar. This phenomenon is called superfecundation.
In March 2019, a woman from the Chinese city of Xiamen in Fujian province gave birth to twins and immediately after their birth did a DNA test - this was demanded by her husband, to whom the children seemed so different that he was ready to bet that one of the sons was not his. …
When the DNA test came, the woman couldn’t believe her eyes: it said that the babies had not one, but two fathers. The Chinese woman first accused her husband of speculation and forgery of DNA tests, but then she was forced to admit that she had a short affair with another man. Geneticists have confirmed that there is no error in the test, although such a case occurs every 13,000.
What happened is called heteropaternal superfecundation - the fertilization of two or more eggs with sperm from different men in one ovulation period. Sperm can live in a woman's body for 4–5 days, and such fertilization most often occurs within a few hours or days after the first act.
The shocked father said that he would only take care of his child, and was not going to raise someone else's.
This is not the first such case in the history of medicine. In 2016, the life of Jessica Allen and her husband Wardell Jasper turned 180. Jessica became a surrogate mother, agreeing to give birth to a child for another couple - the cost of the service was $ 30 thousand. Jessica herself claimed that she just wanted to help a childless family have children.
“No woman in the world should live her life without experiencing the love and bond between mother and child,” she told ABC News.
Such a family was a couple from China, where surrogacy is illegal. In April 2016, the embryo was implanted in Jessica, and nine days later, tests confirmed the pregnancy. But six weeks later, Jessica heard unexpected news: she will have another child. Then it was assumed that the embryo "split", which is very rare, but still happens. Plus $ 5000 for her.
At the 38th week, Allen gave birth, as she was sure, an identical boy and girl. The children were not shown to her, but Jessica saw a photo from which she could definitely say that the kids were not identical.
And a month later, shocking news came: the boy was not the son of a Chinese couple, but the biological child of the Allenov. After some confusion and confusion, the baby was returned to the family to his parents - Jessica and her husband.
