Milwaukee, WI, August 7, 2026 —

A lawsuit has been filed in the Milwaukee area against former OB-GYN Dr. Frederick Dettmann, alleging that he secretly used his own sperm to inseminate a patient in the early 1980s. The patient had sought artificial insemination with the understanding that an anonymous donor would be used.

The alleged deception came to light when the patient’s son conducted DNA testing. The results of this testing indicated that Dr. Dettmann is his biological father, a finding that contradicts the promise of an anonymous donor made during the insemination procedure.

The lawsuit was filed by the family, who claim they were deceived about the identity of the sperm donor. Further details regarding the specifics of the artificial insemination procedure, the timeline of events, and the current status of Dr. Dettmann’s medical practice were not immediately available.
