Should medical device companies face strict liability for manufacturing defects that cause patients emotional distress?
A couple has filed a lawsuit against CooperSurgical, alleging that defective embryo culture media contributed to the loss of an embryo in November 2023. The legal action follows a separate class action settlement involving the same product reached in May 2026.
Why it matters
The case highlights concerns regarding quality control in laboratory products used during IVF, as plaintiffs allege the culture media lacked essential magnesium. This development underscores the ongoing legal challenges facing the manufacturer, with at least 30 related lawsuits currently pending in federal courts.
There are at least 30 lawsuits pending in federal courts concerning the recalled culture media, following the rejection of consolidation by the Judicial Panel on Multidistrict Litigation. The scope of the issue remains under investigation as individual cases continue to proceed separately.
The players
CooperSurgical
A medical device company that produces products for fertility clinics and reproductive health.
The details
The fertility clinic involved in the case reportedly thawed and cultured an embryo in a recalled lot of CooperSurgical media that allegedly lacked magnesium. Patients preparing for these procedures undergo intensive hormone therapy, daily progesterone injections, and hysteroscopy. The lawsuit claims that the failure to include proper ingredients, combined with an alleged failure to warn clinics of development issues, compromised the embryo transfer process.
Timeline
November 2020: L.B. began fertility treatment.

Health Landscape
This litigation occurs as the fertility sector continues to address findings from the 2026 CooperSurgical class action settlement. It highlights the reliance of IVF success rates on the consistency of commercial laboratory media used during embryo development.
Patients currently undergoing fertility treatments may wish to discuss laboratory quality and recall status with their fertility specialist. It is worth asking your clinic if they have implemented new verification protocols for their embryo culture media supplies.
The takeaway
The ongoing legal disputes emphasize the importance of laboratory transparency during IVF cycles. If you have concerns about the materials used in your specific fertility care, consider requesting a consultation with your clinic's lead physician to review their safety standards.
