IVF mix-up leaves woman pregnant with couple’s twins

A woman who underwent fertility treatment at a clinic in Rome became pregnant with the twins of another couple after their embryos were mixed up.

Italy’s health ministry says it is launching an investigation into the error, which was only discovered when the woman was three months pregnant.

The mistake happened on December 4, when four couples with similar sounding names were receiving treatment at a specialist fertility unit at the Sandro Pertini Hospital in Rome, La Stampa newspaper reported.
