What began as a routine stretch of embryo transfers at a Newport Beach fertility laboratory has escalated into a sweeping legal battle. Twenty-three couples have filed lawsuits in Orange County Superior Court against Ovation Fertility, alleging that laboratory errors during a narrow window in January 2024 destroyed their embryos or rendered them nonviable before implantation and cost them their chance at pregnancy.

In vitro fertilization relies on strict laboratory controls at every stage. Physicians retrieve eggs and fertilize them with sperm, and embryologists culture and store the resulting embryos in regulated incubators before transferring them to a patient’s uterus. Even under optimal conditions, success is never guaranteed. Plaintiffs argue, however, that the failed transfers between Jan. 18 and Jan. 30, 2024, did not stem from routine medical setbacks but from a preventable laboratory error.

At the Center of the Legal Battle

Attorneys representing the couples allege that Ovation Fertility’s Newport Beach laboratory made a critical mistake during the January 2024 transfer window. According to the court complaints, a laboratory employee used hydrogen peroxide or another improper cleaning solution on equipment connected to an embryo incubator, allowing chemical residue to enter the environment where embryos were stored and prepared for transfer. The plaintiffs contend that the exposure rendered the embryos nonviable before they were implanted.

The lawsuits center on the outcome of the January 2024 transfer window. According to the court complaints, none of the embryos transferred between Jan. 18 and Jan. 30, 2024, resulted in pregnancy. Plaintiffs say the zero percent success rate during that period sharply deviated from standard IVF outcomes. Attorneys for the couples argue that such a result is highly irregular in IVF practice. Physicians outside the laboratory questioned how every transfer during that window could fail and pressed for closer scrutiny of the clinic’s procedures.

Initial lawsuits filed in April 2024 named nine couples. In the months that followed, additional complaints expanded the case to 23 couples, all tied to the same January 2024 incident. The plaintiffs allege the clinic knew, or should have known, that the embryos were nonviable before proceeding with implantation.

Inside the January 2024 Lab Error

According to the complaints, embryos thawed and prepared for transfer during the affected period were exposed to a toxic environment inside laboratory equipment. Plaintiffs argue that the exposure destroyed viable embryos almost immediately. Yet the clinic proceeded with scheduled embryo transfers.

Patients say they underwent weeks of hormone preparation, routine bloodwork and ultrasounds, and ultimately invasive embryo transfer procedures without any indication that something may have been wrong inside the laboratory. They describe preparing physically and emotionally for implantation, believing the embryos selected for transfer were viable. When pregnancy tests later came back negative, several plaintiffs say they endured additional diagnostic procedures, including biopsies, imaging scans, and further consultations, in an effort to understand why the transfers failed. Only weeks later, they say, did they learn that a laboratory error may have compromised the embryos after physicians began pressing the clinic to explain the unusually high failure rate during that period.

Ovation Fertility has publicly described the incident as an isolated laboratory technician error. The company has said it identified lower-than-expected pregnancy outcomes, initiated an internal investigation, and communicated with affected patients. Ovation has denied knowingly transferring nonviable embryos.

Inside the Legal Claims

The lawsuits accuse Ovation of negligence, medical battery, concealment, and negligent hiring and supervision. Plaintiffs argue that Ovation failed to maintain safe laboratory standards and allowed improperly trained or supervised staff to handle embryos. They allege the clinic implanted embryos that had no chance of resulting in pregnancy and subjected patients to medical procedures without informed consent.

The medical battery claims center on the argument that a patient cannot consent to the implantation of an embryo that is already nonviable. Plaintiffs also allege that Ovation delayed disclosure and attempted to contain the fallout by offering refunds in exchange for liability waivers and nondisclosure agreements.

Ovation has rejected allegations of intentional wrongdoing and maintains that it follows protocols designed to protect embryo health and viability. The company says the issue affected a small number of patients and describes the incident as unintended.

Hope, Loss, and the Human Toll Behind the Court Filings

Beyond the legal arguments lies the personal reality for the couples involved. IVF often requires months or years of preparation. Patients undergo hormone injections to stimulate egg production, surgical egg retrieval procedures, and emotional cycles of anticipation and disappointment.

Several plaintiffs have spoken publicly about their experiences. Brooke Berger and Bennett Hardy of Fullerton said they entrusted their final embryos to the Newport Beach lab after years of unsuccessful attempts. Neither transfer resulted in pregnancy. They later learned the embryos may have been destroyed before implantation. For some couples, the embryos lost during the January window represented their last viable opportunity for biological children.

The emotional consequences extend beyond the courtroom. Patients describe grief not only over failed cycles but over what they believe was a preventable loss. IVF treatments can cost tens of thousands of dollars per cycle, often paid out of pocket. Several couples say their reproductive options are now sharply limited, citing age, underlying medical conditions, and the passage of time as barriers to pursuing additional IVF cycles.

Clinic Response: Isolated Error or Systemic Failure?

Ovation Fertility operates laboratories that support fertility physicians nationwide. In public statements, the company has said it adheres to industry standards and follows established laboratory protocols. It has described the January incident as an isolated, unintended technician error rather than a systemic breakdown.

The company has not publicly explained how the error occurred or confirmed whether hydrogen peroxide caused the damage. It says it launched an internal review after identifying abnormal pregnancy outcomes and contacted affected patients once it discovered the issue.

Plaintiffs’ attorneys argue that a 100 percent failure rate during a specific window signals a serious lapse in oversight. They say discovery in the lawsuit will determine whether additional safeguards were ignored or whether internal alarms were missed.

Oversight Under the Microscope

The litigation raises broader questions about regulation in the fertility industry. Fertility clinics operate under a combination of federal reporting requirements and professional accreditation standards. The Centers for Disease Control and Prevention collects data on clinic success rates, but federal oversight of daily laboratory practices is limited compared with other areas of medicine.

Professional organizations such as the American Society for Reproductive Medicine set guidelines for laboratory procedures, but enforcement largely depends on accreditation bodies and internal compliance. Critics argue that when errors occur, civil litigation often becomes the primary mechanism for accountability.

Fertility clinics across the country have faced lawsuits over embryo mishandling, mislabeling, and storage failures, underscoring the technical precision required in assisted reproductive technology and the serious consequences when mistakes occur. In one high-profile example, a couple in Florida sued an Orlando-area IVF clinic in early 2026 after genetic testing showed the baby born to them was not biologically related to either parent. The couple alleges the clinic mixed up embryos and has asked the court to determine how the error occurred.

Earlier incidents also led to legal action and public scrutiny. In 2018, a cryostorage tank malfunction at a California fertility clinic damaged or destroyed thousands of frozen eggs and embryos. Patients filed lawsuits, and the clinic later reached a multimillion-dollar settlement.

What Comes Next in Court

The lawsuits remain active in Orange County Superior Court. During discovery, attorneys are expected to request laboratory records, equipment logs, and internal communications, and to depose embryologists and administrators involved in the January transfer window. Experts in reproductive medicine could testify about whether the clinic followed accepted standards of care.

If the cases move to trial or settlement, the outcome could shape how fertility clinics disclose adverse events and laboratory errors. Plaintiffs say they seek transparency as well as compensation. They argue that clinics should immediately notify patients if errors jeopardize embryos.

For now, 23 couples have asked the court to determine whether the January laboratory error cost them more than a failed medical procedure. They say it cost them time, trust, and the chance to build their families.
