If to err is human, some are more or less serious consequences. In the Netherlands, the academic medical center UMC has opened an investigation after a probable mixture of sperm for in vitro fertilization (IVF) of 26 women. 

"During the period between mid-April 2015 and mid-November 2016, a procedural infringement occurred in the laboratory of in vitro fertilization (IVF). It is possible that sperm from another couple after treatment found themselves near the egg fertilization of 26 couples. There is a chance that the eggs have been fertilized by the sperm of another man as the father desired"Confesses the UMC in a statement. This would probably be the seed of a single donor that have been inseminated 26 times. "The chances that this is the case are slim, but we can not exclude"Says Dutch university medical center.

Of the 26 women in question, 9 have given birth and 4 speakers. New moms spend a DNA test to verify the relationship of their child. The University Medical Center is also studying how to minimize the consequences for couples and the laboratory. "At first, I was worried. I did not want my baby is not that of my husband. But I am also pleased that UMC does not seek to stifle this case", Testified one of these mothers to CNN. But the news may not make "happy" all women victims of error.
