Conjoined twins are rare and account for one in every 200,000 births.
A Ciudad Juarez, Mexico, mother gave birth to a set of astonishing conjoined Siamese twins.
Conjoined twins born in Mexico who made worldwide headlines yesterday have tragically passed away before any treatment could be conducted.
Again, in December 2016, another conjoined twins with two heads, a neck, chest, two legs and two hands, was delivered at a private hospital in Ogudu area of Lagos.
Sharing a single body and fitted with tubes, a clip of the newborns was posted on social media by their surprised relatives towards the end of last week. It is believed that they shared all of their major internal organs, but each had their own heads and brains. No other details were released by Mexico's Institute of Social Security, which confirmed the death to LaredNoticias.
For reasons that are still medically unclear, female conjoined twins have better odds of surviving than male ones, according to the University of Maryland.
There are also instances when only one of the conjoined twins survive.
The developing embryo then begins to split into identical twins during the first few weeks but stops before the process is complete.
Experts say the partially separated egg then develops into a conjoined foetus. Whether they will attempt to separate the conjoined twins still remains unclear.
The young girls, named Menna and May, will be treated at the kingdom's expense, reports in the Middle East have stated.
