Dr Tulio Jorge Franco has been studying the manner of the unusual pregnancy, which is understood to be only the 20th known case of heteroparental superfecundation to use its scientific term.
It is thought to be the 20th case of this kind to ever be recorded in the world.
Dr Franco, explaining further insight into the case, told G1: "It is possible to happen when two eggs from the same mother are fertilized by different men.
"The babies share the mother's genetic material, but they grow in different placentas.
"It's extremely rare. It happens one in a million. I never imagined that I would see a case like this in my life."
But despite the fact the babies have different fathers, it's understood that only one of the men will be registered on the birth certificate.
The young mum added: "He takes care of both of them, helps me a lot and gives them all the necessary support that they need."
