Fertility Fraud & Unauthorized Sperm

Fertility fraud usually comes to light long after treatment ends. A grown child sends a cheek swab to a genealogy company, and the match list shows a former fertility doctor, his relatives, or dozens of unexpected half-siblings. For the parents, it can mean learning that a promise about the donor, or about a partner's sample, was false. For the person who was conceived, it can upend what they knew about their family and their health history.

What is fertility fraud?

Fertility fraud is the use of sperm, eggs or embryos in treatment without the consent of the patient who received them. The best-known cases involve a doctor who quietly used his own sperm while telling patients it came from an anonymous donor or a medical student. Some laws also cover a donor whose sample was used in a way, or to an extent, the donor never agreed to5.

The cases that became public share a pattern. In Indianapolis, court records reported by the Associated Press said Dr. Donald Cline told patients they were receiving sperm from medical or dental residents or students1. In Vermont, a patient's lawsuit said Dr. John Coates III agreed to use sperm from an unnamed medical student and used his own instead2.

Unauthorized sperm use can take several forms:

• A physician uses his own sperm and tells the patient it came from a donor.
• A staff member or another person supplies sperm that no one was told about.
• A donor's sample is used for a patient it was never released to, or beyond the limits the donor accepted.
• A partner's sample is replaced on purpose with someone else's.
• Records or answers are falsified to hide which sample was really used.

Fertility fraud or an accidental sperm mix-up?

Not every wrong match is fraud. Laboratories handle many samples, and a labeling or handling error can put the wrong sperm into a procedure with no intent to deceive anyone. Physicians writing in a reproductive genetics journal separated embryo or sperm mix-ups from what they called deliberate swaps of sperm samples3. The difference matters, because intent can change which laws apply, who may be charged and what must be proven.

A resemblance, or the lack of one, does not prove anything. Genetic testing is what separates these situations, and the records then help show how the wrong sample came to be used.

How fertility fraud is discovered

Most of the publicly reported cases surfaced through consumer DNA kits. A 2020 article in the Journal of Assisted Reproduction and Genetics estimated that more than 30 million people worldwide had given DNA to such companies, and noted that the deliberate swaps it described were all revealed after people chose to use those kits3. A donor does not need to test for a match to appear. When enough of the donor's relatives are in a database, a donor-conceived person can work out the link through them3.

Discovery can also come through a parent's question, a medical workup, or an investigation. In Indiana, adult children of Cline's former patients filed a complaint with the state attorney general in 2014 after searching online records for biological relatives. Paternity tests performed for the county prosecutor later found Cline was likely the biological father of at least two patients' children1.

Safeguards that should have applied

Patients who used donor sperm were promised specific things: a screened donor, a defined use, and a sample that was what the paperwork said it was. Several rules and standards speak to those promises.

What protects patients in donor treatment

Written consent

Indiana's civil statute turns on whether the patient gave informed written consent to treatment using the provider's own sperm or egg5. California makes it a crime to knowingly use sperm, eggs or embryos for a purpose other than the one shown on the provider's signed written consent form10.

Donor screening

Federal rules require a donor-eligibility determination, based on screening and testing for relevant communicable diseases, before donated reproductive cells are used. Sperm from a sexually intimate partner of the recipient is an exception11. A substituted sample bypasses that screening.

Sample identification

Professional guidelines for embryology and andrology laboratories emphasize sample recognition and identification, according to the 2020 journal article3.

Honest answers

Cline did not face charges for the sperm use itself. His conviction came from lying to investigators, through a guilty plea to two counts of obstruction of justice1.

Using sperm a patient never agreed to is not a treatment choice. It is a breach of the most basic promise in fertility care.

Fertility fraud laws and reported cases

There is no single national fertility fraud law, and state laws are not alike. A 2025 article in the American Journal of Human Genetics counted nine states that criminalize physician fertility fraud4. Many states have no specific statute. The laws below were checked against the official state statute text in October 2026.

• Indiana (civil): A woman who gave birth after infertility treatment, her spouse or surviving spouse, or the child born may sue a health care provider who knowingly used the provider's own sperm or egg without informed written consent. A prevailing plaintiff may recover attorney's fees, the cost of treatment in a patient's case, and either compensatory and punitive damages or $10,000 in liquidated damages5.
• Indiana (criminal): Fraud is at least a Level 6 felony when the offense involves human reproductive material7.
• Texas: The sexual assault statute treats as without consent a procedure in which a health care provider uses reproductive material from a donor, knowing the patient did not expressly consent to that donor. Texas amended the statute in 2019 through S.B. 12598.
• Florida: "Reproductive battery" is a felony, and a more serious one when the practitioner is the donor. Consent to an anonymous donor is not a defense9.
• California: Knowingly using or implanting sperm, eggs or embryos without the required signed written consent is punishable by up to five years in custody, a fine of up to $50,000, or both10.

A criminal case and a civil lawsuit are separate. Prosecutors decide whether to bring charges, and a criminal case aims at punishment. A civil case is brought by the people harmed and seeks money damages. The proof required, the deadlines and the facts that matter can all differ, and a state may allow one, both or neither for the same conduct.

Reported cases and laws, by date

1. 2014

   Adult children of Cline's former patients file a complaint with the Indiana Attorney General's Office1.

2. December 2017

   Cline receives a one-year suspended sentence after pleading guilty to two counts of obstruction of justice. No other charges were filed because Indiana law did not then specifically prohibit the conduct1.

3. 2019

   Indiana creates a civil cause of action for fertility fraud (P.L. 215-2019)5. Texas amends its sexual assault statute, effective September 1, 20198.

4. 2020

   Florida enacts its reproductive battery statute9.

5. March 2022

   A federal jury in Vermont returns a verdict for a former patient and awards her compensatory and punitive damages against Coates. His lawyer said the defense was surprised and disappointed by the verdict2. A jury award can still change after post-trial rulings.

How fertility fraud affects patients and families

The harm is rarely one thing. Writers in the 2025 genetics article, who themselves learned that their genetic fathers were not who they believed, reviewed research on that kind of discovery. In one interview study they described, reactions were mostly negative, and the major effects included adapting to a new identity and grief over a lost genetic connection4.

• A patient learns her body was used in a way she never allowed.
• A partner who planned to be the genetic father learns he is not.
• A donor-conceived person loses a true family medical history. People misinformed about their genetic heritage are also misinformed about that history4.
• Strangers turn out to be half-siblings, sometimes living nearby.
• A sample that skipped donor screening raises health questions no one could answer at the time11.
• Trust in later medical care becomes harder.

When to talk to a fertility fraud lawyer

It makes sense to speak with a lawyer once DNA results point to someone who should not be a genetic parent, especially before contacting the doctor or clinic directly. A fertility fraud attorney can help preserve evidence and check deadlines that may already be running. A review usually looks at:

• What the patient was told about the sperm source, and what she signed.
• What the DNA evidence shows and how strong it is.
• Whether the facts suggest intent, an accidental mix-up, or a donor records problem.
• Which state's law applies, based on where treatment happened.
• Who brings the claim: the patient, a partner, the donor-conceived person, or a donor.
• Whether the physician, clinic or estate can still be identified and reached.
• Any criminal investigation, licensing action or earlier lawsuit.

Who may be responsible

Responsibility depends on the facts and is never presumed. Depending on what the records show, a review may consider:

• The physician who performed the insemination or procedure.
• The clinic or practice that employed or credentialed the physician.
• Laboratory or staff members who handled or labeled samples.
• A sperm bank, if donor records or release limits were wrong.
• A hospital or medical school connected to the practice.
• The physician's estate, if the doctor has died.

Filing deadlines for fertility fraud lawsuits

Every state sets its own time limits, and they vary by type of claim. Because most cases are found decades later, the key question is often when the clock started. Indiana's fertility fraud claim is a clear example. It generally must be filed within ten years after the child's eighteenth birthday. But a claim that would otherwise be too late may be filed within five years of the earliest of three events: DNA analysis first giving enough evidence to sue, learning of a recording that does the same, or the defendant's confession6.

Criminal limits work separately. Florida's reproductive battery statute says the limitation period does not begin until the violation is discovered and reported to law enforcement or another government agency9. Other claims, such as fraud or medical negligence, may carry shorter limits, notice rules or court-filing requirements. A lawyer should check the rules for your state and claim as soon as possible.

Questions

Frequently asked fertility fraud questions

Short answers to questions people ask after a DNA surprise.

Is fertility fraud illegal in every state?

No. Some states have specific criminal or civil fertility fraud laws, such as Indiana, Texas, Florida and California, but others do not. Where there is no specific statute, other claims may still apply. A lawyer can check the law for the state where treatment took place.

What is the difference between fertility fraud and a sperm mix-up?

Fertility fraud involves someone knowingly using sperm the patient did not agree to. A sperm mix-up is usually an accidental error, such as a labeling mistake. Both can cause serious harm, but they are proven differently, and the laws that apply may differ.

Can a donor-conceived adult file a fertility fraud lawsuit?

In some states, yes. Indiana's civil statute, for example, lets a child born as a result of the conduct bring the action5. Other states limit who may sue or have no specific statute, so the answer depends on where treatment happened and which claims are available there.

Treatment was 40 years ago. Is it too late?

Not always. Some states start the clock at discovery. Indiana, for example, allows some late claims within five years after DNA analysis first provides enough evidence to sue6. Other states are stricter. Because deadlines can be short once you know, it is wise to ask an attorney soon.

Do I need a clinical DNA test, or is a consumer test enough?

A consumer test is often how the problem is found. A legal claim may later call for further testing to confirm the relationship. A lawyer can explain what testing may be useful, who should pay for it, and how to keep your current results and account intact.

What if the doctor has died?

A claim may still be possible against an estate, a practice or another party, depending on state law and timing. The records, the estate's status and the deadlines all matter. That is part of what a review looks at, along with who else was involved in the treatment.

Will a criminal case help my civil case?

It can, but they are separate. Prosecutors decide whether to file charges, and a civil case does not depend on one. Cline, for example, was convicted of obstruction of justice, not of using his own sperm1. Evidence gathered in one case may still be useful in the other.

How can I find out my real family medical history?

A genetic counselor can help you understand DNA results and what they may mean for your health. Contact with newly found relatives may also fill gaps. Talk with your own doctor about any health questions, and tell them what the DNA results showed so they can update your history.

Should I contact the doctor or clinic myself?

It is usually better to talk to a lawyer first. Early contact can lead to lost records or statements that are hard to use later. Keep copies of everything you receive, note the dates of any calls, and do not sign anything the clinic sends without advice.

Tell Us Your Story
