A DNA Test Says Your Mother’s Fertility Doctor Is Your Biological Father. What Are Your Legal Options?

A discovery may begin with a consumer DNA test that identifies unexpected biological relatives. Comparing matches and treatment history may raise concerns about the source of the sperm used. Confirmatory evidence is important before drawing conclusions about a particular person’s conduct.

Patients and donor-conceived adults have reported discovering that a treating physician used his own sperm without consent. Examples have arisen in several states, including California and Indiana. Consumer DNA matches may prompt an investigation, but reliable confirmatory evidence and a careful review of the treatment history are important.

Genetic matches can provide a basis for further investigation, but they should be assessed carefully alongside reliable testing and available records.

What happened in these practices

Patients in these disputes allege that sperm was substituted without their informed consent. The investigation may examine what source was authorized, how specimens were identified, and whether independent verification occurred.

Some allegations concern repeated unauthorized substitutions over many years. Establishing the conduct and the people affected requires reliable genetic evidence and a careful review of available treatment records.

What fertility fraud takes from families

From the mother: the right to decide who fathered her child. This was a physical intrusion she did not consent to. Many of these women learned decades later, sometimes in their seventies or eighties, what was done.

For the parents: unauthorized substitution can interfere with an informed decision about the genetic basis of their family and cause substantial distress when discovered.

From the donor-conceived person: an accurate medical history, an accurate identity, and the ability to know who your relatives are. In cities where one physician fathered dozens of children, those half-siblings grew up in the same schools and social circles, and the risk of unknowing relationships between them is real.

For the family: the discovery may undermine confidence in biological relationships and the medical history on which family members have relied.

Fertility fraud laws in California and other states

California. Penal Code section 367g, enacted following allegations of fertility-treatment misconduct in California, makes it a felony to use sperm, ova, or embryos for any purpose other than what the provider consented to in writing, or to implant them in a recipient without written consent. In 2021, California added a specific civil cause of action for violations, allowing victims to recover actual or statutory damages. That civil right of action was not available to earlier plaintiffs and materially changes the picture for California claims.

Other states. Indiana, Texas, Colorado, Nevada, Ohio, Utah, Washington, and a growing list of others have enacted fertility fraud statutes, some criminal, some civil, some both. At least fifteen states now criminalize the conduct. Several statutes create rights of action for the parents and the donor-conceived person, and some start the limitation clock at discovery rather than at the original conduct. There is still no federal fertility fraud statute.

Traditional claims that apply where statutes do not, or alongside them:

• Fraud and intentional misrepresentation
• Medical battery, an unconsented touching
• Lack of informed consent
• Intentional infliction of emotional distress
• Breach of fiduciary duty
• Negligence and negligent misrepresentation

A negligence claim requires proof that the defendant owed a duty of care, fell below the applicable standard of care, and caused resulting harm. For professional negligence, the standard generally reflects the care and skill of a reasonably careful professional in the same field under similar circumstances; expert testimony is generally needed. A poor outcome alone does not establish a breach, and other legal theories have different requirements.

• Unfair business practices

Claims against institutions. Where the physician practiced within a hospital system, university, clinic partnership, or fertility center that still exists, there may be claims against that entity for negligent supervision or for conduct within the scope of employment.

The two hard problems, addressed honestly

Timing. Even if the treatment occurred decades ago, a discovery rule, concealment doctrine, or a specific fertility-fraud statute may affect whether a claim remains timely. None automatically extends every deadline. The applicable statute of limitations depends on the state, the type of claim, the responsible parties, and when the injury was or reasonably should have been discovered. A filing period can be as short as one year, and some claims or required procedural steps may have even shorter deadlines. Notice, administrative, or contractual deadlines may arise before the deadline to file a lawsuit. Do not assume that a clinic investigation, a records request, settlement discussions, or continued treatment stops the clock. Speak with a lawyer promptly to identify and protect every applicable deadline; do not delay while waiting for more information.

Collectibility. Many of these physicians are elderly, retired, or deceased. Malpractice insurers frequently deny coverage on the ground that the conduct was intentional, and most policies exclude intentional acts. Even where liability is clear, there may be no source of payment if there is a finding of civil liability.

A negligence claim requires proof that the defendant owed a duty of care, fell below the applicable standard of care, and caused resulting harm. For professional negligence, the standard generally reflects the care and skill of a reasonably careful professional in the same field under similar circumstances; expert testimony is generally needed. A poor outcome alone does not establish a breach, and other legal theories have different requirements.

The cases most worth pursuing usually have one of the following: a living physician with personal assets, an institutional employer still in existence, a practice entity that continued and has coverage, or a statute providing remedies beyond ordinary compensatory damages.

An investigation can clarify both the potential claim and the practical prospect of recovery. Speak with a lawyer who can assess the evidence, deadlines, responsible parties, and available sources of payment.

What to do if you just found out

The suggestions in this section are non-exhaustive and informational, not directives or legal advice for your situation. Consult a lawyer to develop an appropriate plan. Before any medical or specimen-handling decision, coordinate with your treating doctor and seek immediate medical advice; do not delay urgent care. For each item, request records and explanations in writing, retain original communications, and seek written confirmation of calls. Keep all lawfully obtained documents organized chronologically in electronic form and as hard copies; preserve original audio and digital files as well.

• Consider preserving genetic evidence you are lawfully entitled to access: your raw DNA data, match lists, and screenshots of matches, shared centimorgan values, and listed relationships. Keep the original files and dated written notes about what you observed. Discuss privacy and any proposed contact with relatives with counsel.
• Document the match group. Note every half-sibling match, when you found them, and where they were born. Geographic clustering around one practice is itself evidence. Keep the information organized.
• Discuss whether confirmatory testing is medically and legally appropriate with qualified clinicians and counsel. They can address consent, the testing method, and any chain-of-custody requirements; seek written confirmation of the proposed plan.
• If your mother is living, willing, and has authorized access, consider requesting her insemination records, consent forms, donor descriptions, and billing records in writing through a lawful process.
• With your mother’s agreement, consider making a dated written account of what she recalls being told about the donor or sperm sample. Identify her words and recollections accurately rather than treating later assumptions as contemporaneous records.
• Before contacting the physician or family members about a potential claim, discuss evidence preservation and communications with counsel. Direct contact may affect the investigation or future proceedings.
• Information from biological relatives may help establish the facts. Coordinate any sharing with consent and attention to privacy, and obtain individual advice before negotiating or signing an agreement.

For the mothers

If you underwent the procedure, the discovery may be deeply distressing even many years later. Responsibility for an unauthorized substitution rests with the person who committed it, not with a patient who relied on the agreed treatment. Your medical, emotional, and legal needs deserve an individual assessment.

The treated patient and the donor-conceived person may have different rights and deadlines. Each should receive advice about whether a separate claim is available under the applicable law.
