A Dutch IVF lab in Utrecht has launched an investigation after discovering that up to 26 women may have been fertilized by sperm cells from the wrong man.
“Procedural error” between mid-April 2015 and mid-November 2016 was to blame, The University Medical Centre said (UMC).
The couples who had undergone the treatment have been informed and the UMC said it “will do everything within its powers to give clarity on the issue as soon as possible.”
In a statement, the UMC explained: “During fertilization, sperm cells from one couple may have ended up with the egg cells of 26 other couples. Therefore, there’s a chance that the egg cells have been fertilized by sperm other than that of the intended father.”
Although the chance of that happening is small, the possibility “could not be excluded”, the UMC added.
“For some of the 26 couples, frozen embryos are still available but the chance remains that they (too) have been fertilised by the sperm from a man other than the intended father,” the UMC said.
150 women also have had their fertility treatment suspended while problems in the IVF lab are sorted out, four other hospitals make use of the UMC laboratory and their patients too must now wait until the problems have been solved.
