It may be one of the most disturbing stories of the year, as a woman and her son are looking to sue a gynecologist, claiming he used his own sperm to impregnate her without consent.
They claim that this could also involve other patients, as PEOPLE reports that the complaint was filed in Milwaukee County Circuit Court back on August 6.
It was filed by Mary Ellen Lukezich and her son, Joseph Laedtke Heider, and it dates back to 1980, when the mom was 25 and looking to conceive with her husband Thomas Laedtke.
The Wisconsin mom agreed with her longtime OB-GYN and fertility specialist, Dr. Frederick Dettmann, to go through artificial insemination using sperm from an anonymous donor, who was believed to be a medical student.
Fast forward to 1982, and Lukezich became pregnant and gave birth to Joseph in 1983 - the procedure was a success.
By 2024, Joseph was in his 40s, but a DNA test on Ancestry.com revealed the twisted truth of his genetics.
Dettmann, now 91, was his biological father, the complaint details, with results also revealing that he had half-siblings and other family members whom he didn't know existed.
The mom and son's attorney, Al Foeckler, said that the gynecologist never told Lukezich that he was using his own sperm for the procedure, never getting her consent.
Now, the mom and son are looking for an unspecified amount in damages, which will be finalized at trial.
Joseph released a public statement, saying: “Words cannot fully express what it feels like to learn that your entire identity is built on a lie told by a doctor who took an oath to do no harm.”
He also highlighted the sympathy he has for his mother, stating that "she was a young woman who wanted nothing more than to become a mother."
Joseph and his mom came forward after realizing they might not be alone in this difficult situation, as they have encouraged others to step forward.
A statement read: “If you were a patient of Dr. Frederick Dettmann, if you used his fertility services and have discovered unexpected relatives through DNA testing, please know you are not alone, and we hope you will come forward so that together we can seek the truth and the justice that all of us deserve.”
Speaking to NBC News, Foeckler said that numerous women have come forward, citing “uncomfortable interactions” they had with the health professional.
Now, Sean Gaynor, who is an attorney for Dettman, has disputed claims made against him, telling the publication: “The events referenced are alleged to have occurred almost 50 years ago,
“Dr. Dettmann has no independent recollection of the individuals making these allegations and is unaware of any evidence supporting the claims being asserted.”

A woman discovered that she had accidentally slept with her half-brother after a fertility doctor swapped his sperm to impregnate her mother.
Victoria Hill's story, as reported by CNN, sheds light on the unsettling trend of fertility fraud.
Hill, like many others, turned to DNA testing through services like Ancestry.com and 23andMe to explore her genetic heritage. What she unearthed was beyond her wildest expectations - her biological father was not who she thought he was, and her newfound siblings numbered into the dozens, all conceived through the same fertility doctor her parents had consulted.
"It was traumatizing," Hill expressed to CNN, reflecting on the revelation. "Now I'm looking at pictures of people thinking, well, if he could be my sibling, anybody could be my sibling."
Hill's cause took a further traumatic turn when she discovered that her high school boyfriend - whom she had been intimate with - also took a DNA test and confirmed that he was also her half-sibling. Choosing to remain anonymous, he revealed that he was was also conceived via fertility fraud from the same doctor.
The culprit behind this deception was Dr. Burton Caldwell, who allegedly substituted his sperm without consent or knowledge, leaving a trail of unsuspecting victims.
Janine Pierson, another of Hill's half-siblings, has taken legal action against Caldwell, igniting a debate over the need for stricter regulations in the fertility industry.
"It shouldn't just be, you know, the Wild West where these doctors can just do whatever it is that they want," Pierson argued, echoing the sentiments of many affected by fertility fraud.
While some states have begun to address this issue with legislation, progress has been slow. CNN reports that only about a dozen new laws have been passed in the past four years, leaving significant gaps in legal protection for victims.
Indiana, for instance, emerged as a pioneer in 2019 by criminalizing fertility fraud, albeit two decades behind California. However, the enforcement of such laws remains a challenge, with many perpetrators facing minimal consequences, if any.
The case of Dr. Donald Cline, who fathered at least 90 children in Indiana, epitomizes the magnitude of this crisis. A Netflix documentary released in 2022 exposed Cline's actions, prompting bipartisan efforts in Congress to address the issue at the federal level.
Representatives Stephanie Brice (OK-R) and Mikie Sherrell (NJ-D) introduced the Protecting Families from Fertility Fraud Act, aiming to classify misrepresentation of DNA in reproductive procedures as a federal sexual assault crime. Hill and other advocates have rallied behind the bill, urging lawmakers to take decisive action against fertility fraud.
A fertility doctor from Indiana has been accused of using his own sperm to artificially inseminate patients over a number of decades without their consent. He has now been confirmed to be the father of at least 48 children, but the specifics of the law means he technically didn't commit a crime.
One of these newly-discovered children, the 33-year-old Heather Woock, spoke about what it was like to make the discovery in a report published this week by The Atlantic. After she had taken a DNA test on Ancestry.com in 2017, a stranger reached out, claiming to be her half-sibling. Soon, messages started arriving from others, all of which had been conceived in the same fertility clinic.
Woock's parents had gone to Dr. Donald Cline for insemination from a donor, but didn't know it was actually his sperm that he used. Now, tests from various DNA services have confirmed at least 48 children have been fathered by this doctor, though the number could be even higher - as these only include those who have done DNA tests.

Another woman who discovered this same truth is Jacoba Ballard. In 2014, she began looking for those that had the same biological father, and came across a woman who had also been treated by Cline. Speaking to The Atantic, she said that she knew they were related as soon as she saw their Facebook photos. "I was like, Oh my goodness, I think that is my sister," Ballard said.
After they met, the pair found more who had discovered that they had the same father, their mothers all going to Cline's clinic. After cross-matching their DNA with public databases, the prime suspect became Cline himself.
The doctor told his patients that he'd used sperm donated by medical residents, and that he only used each donor for three pregnancies each. However, tests revealed that he'd used one donor at least eight times between 1979 and 1986 - a much longer period than the usual medical residency.

Ballard and her half-siblings tracked down Cline's family, and met with the doctor in 2016. It was here that he allegedly admitted to using his own sperm to inseminate around 50 unwitting patients during the 70s and 80s. This soon led to a criminal investigation, resulting in Cline being charged with two counts of obstruction of justice during the investigation.
The 80-year-old received a year suspended sentence in December 2017, but there were no other charges filed against him because law in the state doesn't specifically prohibit fertility doctors from using their own sperm in this procedure. Ballard and her other half-siblings have since been campaigning to have the legislation changed to make this a crime.
"I feel like our mothers were violated, he has torn all of our lives apart," Ballard said in an interview with The Associated Press last year. "He cheated himself out of knowing his children. That's what we are."
One woman, who was inseminated by Cline over a dozen times over a five-month period, told the Atlantic: "I feel like I was raped 15 times." She noted how the doctor's office was decorated with photos of the babies he'd helped to conceive, a detail that struck her as far more unsettling once she learned the truth.

A court ruling brought to light a complex and emotional case involving a same-sex couple, a sperm donor, and the legal rights of parenthood.
In a heartbreaking decision, a woman - identified only as P - has been removed from her daughter's birth certificate after it was revealed that her partner - referred to as Q - secretly had sexual relations with the sperm donor father.
As reported by The Sun, the judge presiding over the case, Mrs. Justice Gwynneth Knowles, stated that P had no biological or legal connection to the child and therefore had no right to be listed as a parent on the document.
The ruling followed a bitter High Court battle that shed light on the risks associated with informal arrangements for artificial insemination.
The dispute began after the couple, hopeful to start a family, placed an advertisement for assistance in late 2016. They met the sperm donor in a pub to negotiate terms but faced unsuccessful attempts at artificial insemination.
Devastated by the failures, P turned to the donor for comfort, resulting in a series of secret sexual encounters.
Assuming the pregnancy was the result of artificial insemination, Q was overjoyed when the baby was born in late 2017, and both women were listed on the birth certificate - P as the biological mother and Q as a parent.
However, following the collapse of their marriage and disputes over childcare arrangements, P admitted to her infidelity with the donor.
As a result of the court ruling, Q has been removed from the birth certificate, leaving P as the sole legal parent. Justice Knowles emphasized that Q must come to terms with the lack of legal recognition as a parent, saying: "Q has no biological connection with X and must come to terms with her lack of legal recognition as a parent by reason of my decision."
The judge then stressed that the people involved must be prepared to explain the unique situation to the child as they grow older.
“The fallout from this couple’s separation has been devastating for each of them and for their named sperm donor," Justice Knowles said. “In due course, the child concerned will need an age-appropriate explanation of what happened when she was conceived and why it is that she now has a different birth certificate.”
Justice Knowles described the situation as a cautionary tale, emphasizing the devastating fallout for all parties involved, including the child and the sperm donor.

DNA tests have proven that a Dutch fertility doctor used his own sperm to secretly father 49 children.
Jan Karbaat, who died two years ago in April 2017, impregnated the women at his clinic in Bijdorp, near Rotterdam in the Netherlands, with none of the women aware that he was illegally using his own semen in the operations.
However, it is feared that he could have fathered many more children than the 49 identified.

The court case began in 2017 when 22 children applied for legal help in resolving their true heritage after suspicions grew they could be related. Many of them bore close physical resemblances and had highlighted irregularities between their appearances and the appearances of their alleged donors.
The doctor is said to have told a donor child in 2011 that he used his own sperm to inseminate women, but always denied the claims, with the legal case against him starting shortly before he died aged 89.
When he was alive, a judge felt there was insufficient evidence to allow the test and when he passed away, his family fought against the use of his DNA, which was allegedly extracted from personal items including his toothbrush.
However, following a two-year legal battle from dozens of his children and their parents, a court ruled in February that his DNA could be released.

Results released on Friday proved that Karbaat was the father of the 49 children, said the group Defence for Children which had supported the case.
"The judge placed the interest of the child above the right to privacy of Mr Karbaat and his family," said Defence for Children adviser Iara de Witte."After years of uncertainty, the plaintiffs are finally closing a period and they can start processing the fact that they are one of the many descendants of Karbaat."
Martijn van Halen, one of Mr Karbaat's children, told Dutch news website nrc.nl that he felt good about finally getting the truth, stating: "It's nice to know for sure. It gives peace."
Another of the children named Joey, said he could "finally close the chapter" now he knew Karbaat was his father.

"After a search of 11 years I can continue my life. I am glad that I finally have clarity," he told Dutch broadcaster NOS.
Many of the children, most of whom are now in their 30s, have become friends after their lengthy legal bid and claimed they would be keeping in touch.
Tim Bueters, a lawyer who represented the children, claimed he was pleased to have results of the case after years of uncertainty.
"It means that there is finally clarity for the children who are matched," he told NOS.
Karbaat's clinic was closed in 2009, amid allegations of false data, and methodical exceeding of the permitted number of six children per donor.
A couple who say they were promised they would have a baby girl by a fertility clinic is suing them after their baby turned out to be a boy.
Heather Wilhelm-Routenberg only agreed to have children with her wife Robin (Robbie) Routenberg-Wilhelm on the condition that they had girls because of sexual assault trauma.
The CNY fertility clinic in Latham, New York, assured them that they could accurately determine the sex of an embryo before transferring it into Heather's womb, the pair say. So the Buffalo couple were shocked when - at 15 weeks pregnant - they discovered they were having a boy.
In a first-person piece for the New York Post, Heather opened up about the trauma surrounding her pregnancy and detailed their legal case against CNY, who they are suing on 11 counts including breach of contract, medical malpractice, and battery.
Heather begins by explaining how the clinic took an egg from Robbie and donor sperm to create the embryo, which was then transferred to her womb.
"We selected CNY because they agreed we would be able to select female embryos," she recalled, before explaining that: "We didn’t want to have a boy because of the assaults and because of the socialization of boys — there’s constant socialization of what it means to be a 'real man.' People say, 'Oh, he’s a boy, let him hit you,' and all the camouflage and guns don’t help. It reinforces masculinity, and that’s a reminder of the assaults every time."
Robbie added that, while she didn't have Heather's trauma to contend with, she was also against having a boy because of enforced masculinity, saying: "We did not sign up for that."
When they discovered that Heather was in fact pregnant with a baby boy, the couple was convinced that they had been given the wrong embryo. "That’s when I flipped out," Heather described, adding: "That’s when I felt my body was taken hostage."
"It scared the s*** out of me. I don’t know how to explain this — it felt like there was an alien living inside of me," she continued.
It took seven weeks to determine that Heather was in fact carrying the correct embryo, during which time she describes having no connection with the baby growing inside her. When their son was born in December 2020, both mothers struggled to bond with their son and Heather became suicidal.
Since then, they have managed to bond with their son and now love him as well as any parent could. However, they still feel that the fertility clinic robbed them of that initial connection.
"He’s an innocent being, he didn’t deserve any of this. The clinic messed with something so integral: our baby’s first formative years. That’s the reason I am doing this — because I love my kid so much. We think our son deserved that bond from the start," said Heather.
