SALT LAKE CITY -- The University of Utah is investigating an artificial insemination case after a couple discovered that their daughter isn't biologically related to her father.

The artificial insemination was performed more than 20 years ago at a Utah fertility clinic, which has since closed. DNA testing recently revealed no genetic match between the father and daughter, which lead to the discovery that the father's sperm had been switched at the clinic.

FOX 13 News' Max Roth took a closer look at the incident, see the video above for his report.

The University of Utah released the following statement regarding the investigation.

"Since April 2013, the University of Utah has been investigating credible information regarding the possible mislabeling or tampering of a semen sample at RMTI (Reproductive Medical Technologies, Inc.), a private andrology lab owned by a University faculty member (now deceased). The facility was a private laboratory located in Midvale, Utah. While not owned or operated by the University, the University contracted with RMTI for specimen preparation and semen analysis. Additionally, RMTI prepared semen samples for private physician offices throughout the community, not University physicians.

Through genetic testing, a woman who received artificial insemination (AI) in 1991 discovered the biological father of her child was not her husband, as she had assumed. She traced the genetics of her child to a man who was a former employee of the now-defunct RMTI, which may have prepared the AI sample. The man in question was also a part-time employee of the University from 1988-94.

There are no remaining records from RMTI to prove the claim and the man in question has been deceased since 1999. Consequently, it is unknown how this incident might have happened. In addition, there is no evidence to indicate this situation extends beyond the case in question. We understand this information has been upsetting for the family and other clients of RMTI. We want to help alleviate this distress by providing professional genetic testing for RMTI clients who were treated between 1988 through 1994.

Concerned individuals should contact the University of Utah Andrology Lab at 801-587-5852."
