You might have seen a mother giving birth to two babies simultaneously, but have you heard that the twins are actually not the twins as they possess different parental genes. If no, then let me make this thing clear.
A surrogate mother can also conceive during her pregnancy and we have a handful of examples for the same. For Example, a Californian Women Jessica Allen (31-year-old) gave birth to surrogate twins and later she discovered that out of the twins one baby was her own. The babies whom she gave birth are not actually twins.
Stephen Robson, president of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) gave a confirmation that the case is natural but a “very rare” one. As according to a newest publish by The New Daily, Dr. Robson revealed that it is rare to go pregnant during pregnancy but this is not impossible.
“Usually only one egg is released each month, but it is quite possible that when an embryo is placed in the womb of a surrogate, the woman will ovulate herself and have relations with her partner and … voila!” Dr. Robson said.
“I have only seen this once in my 26-year career, or at least only one that I’m aware of.” He added.
Professor Mark Umstad, maternity services director at Melbourne’s Royal Women’s Hospital, said the scenario can be possible and can have two proven explanation for that.
The two cases are ‘Superfecundation’ and ‘Superfetation’ in both the cases a female can get pregnant during her pregnancy.
Superfecundation – It is the fertilization two eggs from two different episodes of sexual mating or artificial insemination, which occurs within one ovulation cycle.
Superfetation – This type of fertilization occurs when second egg gets conjugated with the sperm in a different cycle when the first embryo is already developing in the uterus.
“I have only seen this once in my 26-year career, or at least only one that I’m aware of.” He also said “It’s never been proven and it would be very hard to prove. It’s an extraordinarily unlikely if not impossible event.
He added that there are many natural changes in female ovulation cycle and reproductive tract which prohibits second fertilization like the changes in the lining of Uterus, the thickening of cervical mucus which prevents entry of sperm into the upper tract, the hormonal changes in a female that stops ovulation or release of another egg.
When the surrogate mother came to know that out of the two babies, one was her which was then proven by DNA reports. The Chinese couple who paid Ms. Allen for the surrogacy demanded $US22,000 for the return of her baby. The legal dispute was considered under Superfecundation and the surrogate mother got her baby without any fee but she had to spend $US3000 as a lawyer service charge.
