Twice the double trouble for IVF couple with two sets of twins

14th April 2011

A couple in America who were unable to have children of their own are celebrating the birth of their twin sons and twin daughters, conceived by IVF.

Miranda and Josh Crawford beat odds of around one in 10,000 to see the birth of two sets of identical twins, after two embryos were implanted during the IVF process.

The Crawford's doctor, Seth Katz, told the Charlotte Observer: "About twice a year, we'll see one (embryo) split. To have both implant and both split is very unusual ... I'll go my whole career without seeing this happen again."

Mrs Crawford carried the babies to 34 weeks, before going into premature labour. The babies were born by caesarean section and have only experienced minor health problems since birth, the news provider said.

Pregnancy website Baby Center says that the chances of a couple undergoing IVF having more than one child are between 20 and 40 per cent.

Natural pregnancies have around a two per cent chance of resulting in twins, triplets or other multiple births.
