Rebecca Roberts experienced a unique event when she gave birth to twins, a boy and a girl.
What makes this case even more interesting is that doctors have established that these two children were conceived at different times.
At the very beginning of her pregnancy, Rebecca thought she was expecting twins, but during the first ultrasound, only one fetus was detected, which is typical in the early stages of pregnancy.
However, later a second fetus was discovered, and the reason turned out to be unique.
The twins, who were named Noah and Rosalie, were born with a big difference in weight: the boy weighed around two kilograms, while the girl weighed only 1.2 kilograms.
Such a difference in weight is usually characteristic of multiple pregnancies, but in this case it was particularly significant.
Further research and analysis of medical data determined that Rosalie was conceived three weeks after her brother, a rare and remarkable phenomenon known as “superfertilization.” This case of Rebecca is the 14th of its kind in the world.
It is assumed that one of the possible reasons for the superfertility in this case was the use of drugs to treat infertility.
Apparently, these medications continued to impact Rebecca’s eggs even after the successful pregnancy began, allowing for secondary conception.
Due to their low weight, the twins spent some time at the clinic before the Christmas period, after which they were allowed to return home, where their 14-year-old eldest, Summer, welcomed them. Currently, the twins are doing well and growing actively.
