Former Whitefish Bay OB-GYN accused of artificially inseminating patients with his own sperm

WHITEFISH BAY, Wis. (CBS 58) -- A woman is claiming her former Whitefish Bay OB-GYN artificially inseminated her with his sperm without her consent.

Mary Ellen Lukezich says she relied on OB-GYN Dr. Frederick G. Dettmann when looking for fertility treatment as she looked to conceive a child back in April 1980. Dr. Dettmann reportedly worked for decades at 5589 North Bay Ridge Ave. in Whitefish Bay, practicing obstetrics, gynecology and infertility medicine.

According to her lawyer, Lukezich consented to artificial insemination using the sperm of a medical school student, who was an anonymous donor. She gave birth to her son, Joseph Laedtke, on Feb. 14, 1983.

Laedtke, with genealogy testing, reportedly discovered his father had several other biological connections and was able to trace it all back to Dr. Dettmann. Laedtke and Lukezich believe they're not the only victims, as Laedtke, through the genetic testing, discovered "multiple half-siblings."

Now, other women who were patients of Dr. Dettmann and underwent artificial insemination from an anonymous donor are asked to come forward.

Whitefish Bay Police released police logs from back in 1985 and 1986 where a woman accused Dr. Dettman of sexually assaulting her. On Aug. 19, 1985, a man stated his wife was sexually assaulted while in a gynecological exam with Dr. Dettmann. The doctor denied the allegations. The next day, the assistant District Attorney reportedly declined to issue charges as "burden of proof was too difficult."

Then in April of 1986, the Medical Examining Board "considered the relevant facts and voted to close this case without further action." We reached out to the Board for more information and comment, but have not heard back. Whitefish Bay Police say they have no other records since they were "destroyed according to records retention laws that were in place at that time."

There are no current investigations at this time, per the Whitefish Bay Police Department.

Dr. Dettmann, according to Wisconsin's Department of Financial Institutions, registered with the state in September of 1976 and dissolved his practice in December of 1997. He's believed to now be a 92-year-old man who lives in Scottsdale, Ariz. CBS 58 has reached out for comment and has not heard back.

We also reached out to Whitefish Bay police to learn if they're investigating the case.
