Botch up means 26 women got wrong IVF sperm

Organisation: Position: Deadline Date: Location:

A mistake at a Dutch IVF clinic means that up to 26 women may have accidentally had their eggs fertilised with the wrong sperm, reports The Independent.

After a “procedural error” at the University Medical Centre in Utrecht that happened between mid-April 2015 and mid-November 2016, as many as 26 couples may have had egg cells fertilised with sperm cells from another couple, the centre has said.

“During fertilisation, sperm cells from one treatment couple may have ended up with the egg cells of 26 other couples,” a statement from the centre said. “Therefore there’s a chance that the egg cells have been fertilised by sperm other than that of the intended father.”

The chance that the mistake has happened is small, and may not have happened to all of the 26 couples, the centre is quoted in the report as saying. But the possibility “could not be excluded”, it said. All of the affected couples have been informed, it said. It has launched an investigation to give more information about what might have happened.

The report says half the women who underwent treatment have already become pregnant or given birth. Others may have embryos frozen at the clinic that have all been fertilised by sperm from someone else.

Similar mistakes have led to serious mistakes in the past. In 2012, a Singapore mother alleged that her clinic had mixed up the sperm intended for the father – she had noticed that something appeared to be wrong when her child had a markedly different skin tone from her caucasian husband, according to news reports.
