    Lieff Cabraser’s Fertility Cases & Investigations

    Ovation Genetics / Ovation Fertility

    Lieff Cabraser represents individuals and families harmed by a massive laboratory failure involving preimplantation genetic tests (PGT) performed by Ovation Genetics/Ovation Fertility on embryo samples, where thousands of PGT results generated by Ovation over the span of months were found to be unreliable and inconclusive. These tests are performed on viable embryos after thawing and just before implantation, seeking to confirm the presence or absence of serious birth defects and other illnesses. Families have reported receiving PGT results from Ovation and making significant family-planning decisions based on these results, including the implantation or destruction of precious embryos, only to later discover the reports they received were faulty.


    Lieff Cabraser represents numerous hopeful parents who allege CooperSurgical’s solution used in the IVF process resulted in the destruction of their precious embryos. CooperSurgical is a global supplier of products for IVF and reproductive clinics worldwide, including the media that clinics use to develop the fertilized eggs into embryos. Prospective parents have accused CooperSurgical of failing to conduct thorough testing on their embryo culture media, and that the company’s defective product and negligent conduct destroyed irreplaceable embryos. In December 2023, CooperSurgical issued an urgent recall for three lots of its solution, noting “the risk to health is impaired embryo development prior to the blastocyst stage.”

    Lieff Cabraser’s clients, Zachary and Kearsten Walden, were recently featured in The New York Times and USA Today sharing their story of how they were impacted by CooperSurgical’s failures.

    Bloomberg Law recently covered two lawsuits our team filed against prominent fertility treatment company CooperSurgical on behalf of plaintiffs whose embryos were damaged or destroyed by the use of a defective solution. Read more about these lawsuits on Bloomberg Law.

    Natera / Thermo Fisher

    Lieff Cabraser currently represents families devastated by faulty Natera preimplantation genetic tests. Natera, Inc. is a clinical genetic testing company based in San Carlos, California that specializes in non-invasive, cell-free DNA testing technology, with a focus on women’s health, cancer, and organ health. Natera boasts a standard failure rate of less than 2% for the genetic test it offers to families undergoing IVF to confirm the health of their precious, irreplaceable human embryos.

    Yet, for months, Natera used a defective testing solution manufactured by Thermo Fisher Inc. during the PGT testing process, resulting in hundreds of “no-call” results. Because the genetic tests are performed on viable embryos after thawing and before implantation in an effort to confirm the presence or absence of serious birth defects and other illnesses, these faulty test results left families with devastating losses and impaired future family planning.

    Columbia University

    Lieff Cabraser is investigating reports that Columbia University Fertility Center mismanaged their storage and inventory of cryopreserved human eggs and embryos. Individuals have reported being informed they had no viable embryos being stored by Columbia, only to later receive a collections letter for the costs of storage of viable embryos that they did not know existed. If you have experienced mismanagement of your reproductive material stored at Columbia University Fertility Center, we urge you to talk to Women’s Health Lawyer and Lieff Cabraser partner Sarah R. London today about your rights and potential recovery.

    RMA/Weill Cornell Medicine Fertility Lab Failures

    Lieff Cabraser is investigating reports of laboratory failures and surprising IVF results at the Ronald O. Perelman and Claudia Cohen Center for Reproductive Medicine (CRM) of Weill Cornell Medicine. Individuals have reported multiple laboratory deficiencies, including laboratory procedure deficiencies resulting in failed IVF cycles and a lack of accreditation. If you were affected by a fertility laboratory failure at CRM/Weill Cornell, we urge you to talk to reach out to our team today about your rights and potential recovery.

    Our Experience

    Pacific Fertility Center

    In June 2021, plaintiffs won a $15 million verdict in the Pacific Fertility Center cryogenic tank failure & embryo destruction lawsuit. Lieff Cabraser represented families and served in leadership roles in both state and federal court, where partner Sarah London was the court appointed Liaison Counsel in state court and Interim Class Counsel in the federal action. The jury found the freezer tank manufacturer to be most at fault, though the clinic also shared some of the blame for the tragic losses. In the 2018 complaint, hopeful parents alleged the clinic destroyed or seriously damaged hundreds of cryogenically preserved eggs and embryos stored at its facility in San Francisco after liquid nitrogen depletion in one of its storage tanks.
