A mother who gave birth to two babies from different mothers and then had to give them up has won a payout from the clinic in California that mixed up the embryos.

The Asian-American couple who were only ever identified by their initials have settled for an undisclosed sum with the Cha Fertility Clinic in Southern California, according to reports.

In 2018, the couple, identified as YZ and AP, from Flushing, New York, travelled to California and paid $100,000 for fertility treatment. It resulted in eight embryos and a pregnancy for AP, who was told she was having twin girls.

When she gave birth, she did so to two Caucasian boys rather than two girls with Asian features. Subsequent investigations revealed that in an “unimaginable mishap” the clinic had implanted two male embryos from two different families into AP, according to a lawsuit they filed.

A few weeks later, the couple were forced to give up the baby boys. Their lawsuit said they had suffered “permanent emotional injuries from which they will not recover”.
