Superfetation is the implantation of a new pregnancy into a uterus that already contains a developing pregnancy.
This case is extremely rare in man, the superfetation has occurred only 10 times in the history of modern medicine. In recent years there have been four cases: 2009 in Arkansans, 2015 in Australia, 2016 In the United States (California) and in 2017 once again in the United States this woman is named Jessica Allen.
Fetuses will be of different sizes, weights and ages in some cases may also be of different fathers; No story of Twins.
The delivery of the first baby will engender that of the second, as in the case of twins.
Jessica Allen is a surrogate who rented her belly to an Asian couple, she was expecting twins actually that’s what we thought after a few weeks of the birth of babies parents complain that babies are not alike after various analyzes it was found that the twins were not actually twins, a first fertilized egg was implanted into Jessica’s body but she herself had become pregnant naturally shortly afterwards and that the children were two distinct couples.
Superfetation in man is in fact a mystery, it is a phenomenon that the greatest gynecologists of the world can not explain so far, a second pregnancy would not be possible because the first one, already at an advanced stage, does not would not allow the implantation of a new egg; The mystery of the human body “The first fertilized embryo is implanted in the lining of the uterus, followed by a second a few days later, there would be no negative effect for babies, other than the usual risks associated with the birth of Twins.
