CooperSurgical IVF Lawsuit

During an IVF procedure, fertility doctors use a laboratory process to fertilize mature egg cells with sperm to create a viable embryo.

Before implanting the embryo in the patient’s uterus, doctors place the combined sperm and egg cells in a culture medium (a nutrient-rich fluid). This fluid helps it grow to the blastocyst stage and begin development.

Some viable embryos may have been lost because of defective IVF culture medium made by CooperSurgical. This led people to file defective embryo fluid lawsuits against CooperSurgical.

Plaintiffs allege that CooperSurgical manufactured and distributed a defective embryo fluid for use at IVF clinics across the country.

The IVF process is complex, emotionally taxing and full of variables. The loss of otherwise viable embryos can jeopardize the plaintiffs’ chances of ever having children. The possibility of corporate negligence can make the loss of the embryos even more painful.

IVF is also a costly procedure that insurance providers might not cover. A round of IVF can cost $40,000 to $60,000 and can take months or even years. This could make it difficult or impossible for affected couples to afford another round of IVF if one fails.

How many people are suing for embryo loss from the defective IVF solution?

As of June 2025, more than 30 cases have been filed against CooperSurgical for defective IVF fluid in the U.S. District Court for the Northern District of California, as well as a handful of other state and federal courts. These defective IVF fluid lawsuits against CooperSurgical are still in the early stages. As news about the defective fluid comes to light, more plaintiffs may come forward. There are no class action lawsuits or multidistrict litigation (MDL) dockets related to the individual lawsuits.

The details of each lawsuit vary. For example, one plaintiff lost six embryos. The plaintiff of an earlier lawsuit in Los Angeles claimed to have lost 34 embryos.

The IVF solution — also known as an embryo culture media or global media — used to grow embryos was missing magnesium, a critical nutrient for embryo development. The affected lots contained nearly 1,000 bottles of culture media that were shipped worldwide. One bottle provides enough fluid for multiple IVF patients.

After the distributors received the culture media, they sent it to fertility clinics. CooperSurgical is the entity that made the defective embryo fluid and shipped it to distributors. CooperSurgical has not disclosed why the culture media was made and shipped without magnesium.

How do I know if my embryo loss was caused by defective fluid?

If you’ve gone through the IVF process and lost embryos, it’s difficult to say whether the defective CooperSurgical IVF solution is the cause. In most IVF legal cases, patients don’t know what solutions were used during their procedures. Additional research is needed, starting with your fertility clinic provider.

Motley Rice attorneys can help you investigate whether your fertility process may have been impacted by the defective fluid. This information will determine if the recalled batches of fluid were used during your IVF treatments. Lawyers can also analyze applicable laws to see if you might be eligible to file a lawsuit seeking financial compensation.

Embryo loss plaintiff details

More than 30 plaintiffs have filed IVF lawsuits against CooperSurgical. That number is likely to grow as tens of thousands of patients undergoing IVF may have been affected. Currently, the plaintiffs include:

• A couple undergoing fertility treatment in Los Angeles. They claim to have lost 34 embryos.
• A couple from Virginia who were unable to conceive via IVF after a decade of other unsuccessful efforts.

The CooperSurgical embryo lawsuits are still in the early stages of litigation. Motley Rice has represented women harmed by defective birth control devices, breast implants and transvaginal mesh devices. Our lawyers have the knowledge and experience necessary to file a CooperSurgical IVF lawsuit.

The Food and Drug Administration (FDA) posted a recall notice about the defective CooperSurgical IVF fluid in December 2023. An updated recall notice confirmed the absence of magnesium in March 2024. The Class 2 recall affected three lots of products totaling nearly 1,000 bottles, which may have affected up to 20,000 patients.

The FDA defines a Class 2 recall as a situation in which:

• The affected product may cause temporary or medically reversible adverse health consequences
• There’s a remote probability of serious adverse health consequences

Class 1 is the most serious of the three recall classes. There are also recall categories for market withdrawals and medical device safety alerts.

More about CooperSurgical

According to The New York Times, CooperSurgical’s 2023 revenue reached $1.2 billion. Forty percent of that came from its fertility products and services. According to some estimates, the total IVF market in the U.S. was worth more than $25 billion in 2023.

CooperSurgical is also involved in other litigation besides the defective IVF culture media recall. Plaintiffs in an MDL action claim the company knowingly sold defective Paragard intrauterine devices (IUDs). These defective IUDs caused injuries and serious health problems to thousands of people.

The goal of IVF is the implantation of an embryo into a uterus, where it can develop into a healthy baby. An entire IVF cycle takes four to eight weeks. Here are some of the key steps in the IVF process.

• Initial screening: This step includes various tests to determine how many eggs are available, analyze semen, screen for infectious diseases  and examine the uterus
• Egg development: The IVF team might use hormones to stimulate the ovaries to make eggs. The process requires multiple eggs because some won’t fertilize. Other medicines might help the eggs mature, prepare the uterine lining or delay ovulation until the opportune moment.
• Egg retrieval: Fertility specialists retrieve the eggs from the ovaries.
• Sperm retrieval: Doctors harvest sperm cells from a semen sample.
• Fertilization: The IVF clinic will attempt to fertilize the eggs in a petri dish and place them in the embryo culture media.
• Embryo transfer: The embryo is implanted in the uterus. If the process is successful, the embryo will attach to the uterine lining. It will take approximately 12 days to determine whether or not the patient is pregnant.

For many, successful IVF procedures provide the opportunity to build the family they desire. If your IVF procedure did not work and you believe you may have been impacted by the defective CooperSurgical fluid, contact us today.

Is IVF difficult for patients?

Yes, IVF procedures are difficult. Patients must take hormone injections and other medications. The injections have known side effects, including:

• Abdominal pain
• Bruising
• Bloating
• Blood vessel clots
• Bone loss
• Depression
• Diarrhea
• Discomfort, redness or swelling at the injection site
• Fatigue
• Headaches
• Muscle aches
• Strokes
• Vaginal dryness
• Vaginal yeast infection
• Vomiting
• Water retention
• Weight gain

The IVF process includes routine blood tests and invasive transvaginal ultrasound examinations. These tests may restrict the patient’s diet along with their ability to work and travel.

Egg retrieval can also be difficult. Patients are placed under anesthesia while the doctor inserts a large needle in the vaginal wall to extract eggs. The patient may experience pain for up to a week and may need days of bed rest.

Did CooperSurgical know its IVF culture media was defective?

Yes, CooperSurgical was aware of its defective product. The company voluntarily recalled three batches of IVF fluid in December 2023. IVF lawsuits, however, also argue that the company should have been quicker to recall the affected batches.

How many people were affected by the defective IVF fluid?

The number of people affected by the defective CooperSurgical IVF product could reach many thousands. The company recalled three batches containing nearly 1,000 bottles. Each bottle can provide culture media for multiple patients.

Lab director Mitchel C. Schiewe of California Fertility Partners told The New York Times that up to 20,000 patients could be impacted if even half the affected bottles were used.

How much is an embryo loss settlement?

No defective IVF fluid lawsuits have gone to trial or been settled yet, so it’s difficult to estimate settlement amounts and a settlement is not guaranteed. Any compensation amounts may depend on the economic losses from the IVF treatment as well as the pain and suffering of the plaintiffs. The possibility of the plaintiffs producing another embryo may also be a factor.
