This is a very disturbing website. A man recently learned that he is not the father of his daughter. He and his wife are shocked because it turns out that the biological father was a man who worked at the IVF clinic.
They found out quite by accident as shown in this video.
The clinic worker is dead and the clinic is gone. The university associated with it is refusing to warn people about the possibility that this nutjob Lippert may have done this many times because "the burdens of this information are likely to outweigh the benefits to families."
Now the couple has a website as an attempt to warn people.
We believe that it is possible that Thomas Lippert has many biological children living in the Salt Lake City area, Minnesota and beyond. The parents of these children may be completely unaware that their child is not biologically related to the presumed father. If you or someone you know was conceived through artificial insemination at the fertility clinic associated with the University of Utah, otherwise known as Reproductive Medical Technologies, you need to be aware of this potential. We encourage you to have your children tested at one of three companies offering genealogy DNA tests where the biological relatives of Thomas Lippert have tested for comparison purposes. These are 23andMe, AncestryDNA and Family Tree DNA. This is not a legal paternity test and is for informational purposes only.
Although some may feel that it is preferable not to know if Mr. Lippert is the biological father of your child, we believe the knowledge of biological heritage is essential to avoid half-siblings who may be living in the same communities potentially engaging in romantic relationships, as well as for family medical history.
Thomas Lippert worked at the fertility clinic from 1986-1997 or 1998, but began donations in 1983. It is possible that his sperm sample was exchanged with other intended fathers' samples and/or was frozen under other names and used after this time.
