Going through an in vitro fertilization (IVF) cycle requires your full focus. You are managing hormone stimulation, egg retrievals, and fertilizations—all while investing an incredible amount of physical, mental, and emotional energy into the immediate steps required to build your family.
Once your family is complete, however, a quieter but highly personal question often arises: what should we do with our remaining frozen embryos?
Deciding what to do with remaining embryos is a common and practical step that comes at the close of active IVF treatment. If you find yourself in this position, we are here to outline the options and help you establish a clear plan, so you can make your choice and move forward with confidence.
What Happens to Unused Embryos after IVF?
At the end of an IVF process, it is standard to have viable embryos in cryopreservation. Fertility specialists typically retrieve and fertilize multiple eggs during a single cycle to maximize the chances of a successful pregnancy, which frequently results in remaining embryos once family-building goals are met.
When you are ready to transition out of active treatment, understanding your choices is the first step. Generally, there are five options available for remaining embryos:
- Long-Term Storage: Keeping the embryos frozen to provide more time to make a decision or for potential future use.
- Donation to Another Family: Transferring legal parentage of the embryos to another individual or couple to help them build their family.
- Donation to Scientific Research: Contributing the embryos to medical science to assist researchers in studying developmental biology, genetic conditions, or infertility treatments.
- Clinical Thawing and Discarding: Having the embryos thawed and disposed of respectfully by a fertility clinic or cryobank.
- Compassionate Transfer: Having the embryos clinically transferred back into the uterus at a specific time in the cycle when pregnancy is biologically impossible, allowing a natural end.
The direction you take depends on your personal values, financial picture, clinic policies, and the legal framework you put in place with your team.
Deciding What Feels Right for Your Family
Choices about embryo disposition involve paperwork, but they also reflect your values and long-term plans. Because there are several factors to weigh, individuals and couples often find it helpful to collaborate with professional counselors, matching agencies, and specialized legal counsel.
From our perspective at Foster + Bloom, we see matching and adoption agencies as collaborative resources. They provide the dedicated coordination, screening, and practical support that allow you to explore your options comfortably. Meanwhile, our legal team ensures your parental rights and interests are secure.
Before moving forward, we suggest thinking through these questions:
- How do we feel about another family raising a child who shares our genetic background?
- Are we comfortable contributing to scientific studies that might assist future generations?
- What are the ongoing storage costs, and do they align with our long-term financial planning?
- What timelines and requirements does our fertility clinic have for embryo disposition?
Keeping Embryos in Storage
For many people, the most sensible immediate choice is to keep embryos in cryopreservation. This is a practical option if you want more time to process the possibilities or are keeping the door open for the future.
While many fertility clinics offer on-site cryopreservation, others partner with specialized, off-site storage facilities designed for long-term maintenance.
Frozen storage requires ongoing annual fees, which vary depending on the facility and the terms of your contract. Because of this, it is important to keep your contact and billing information up to date with your facility. This keeps your storage agreement active and protects your stored material from accidental abandonment clauses, keeping your legal interests intact.
How Long Can Frozen Embryos Be Stored?
Scientifically, modern vitrification (ultra-rapid freezing) techniques allow embryos to remain frozen almost indefinitely. Healthy children have been successfully born from embryos stored for several decades, with no increased risk of developmental or genetic abnormalities due to the length of time frozen.
In practice, however, personal choices and legal factors usually dictate storage timelines. When setting up long-term storage, a clear legal plan helps address unexpected life events, such as:
- The death of one or both partners.
- A relationship separation or divorce.
- Clinic restrictions regarding age limits for transfers.
Establishing a customized legal agreement early ensures your preferences are documented and respected, regardless of how circumstances may change.
Donating Embryos to Another Family
Some people choose to donate their remaining embryos to assist others. Embryo donation offers an alternative path to parenthood for intended parents facing barriers to conception.
The donation process follows structured steps to ensure safety and clarity for everyone:
- Medical Screening and Eligibility: Donating parties must meet embryo donation requirements set by the FDA and individual fertility clinics. This includes a detailed medical history review, infectious disease screening, and genetic testing.
- Agency Matching: Many families collaborate with specialized embryo donation programs or matching agencies to connect with a receiving family. These agencies offer screening and administrative coordination to facilitate a connection.
- The Legal Contract: Before medical transfers can take place, both the donating and receiving parties must sign a formal embryo donation contract.
Working through this process benefits from the guidance of an experienced family formation attorney. Your embryo donation contract must explicitly state that you are relinquishing all legal parental rights, establishing that the receiving parents will hold full, sole legal parentage.
A detailed agreement also outlines expectations for future contact—such as open, semi-open, or closed communication—providing clarity for everyone moving forward.
Donating Embryos to Research
Donating embryos to medical research is an option for those who wish to contribute to broader health advancements. These embryos are typically used in studies focusing on developmental biology, genetic conditions, or advanced infertility treatments. Where permitted, donating embryos for stem cell research is also a possibility, aiding scientists in studying therapies for complex conditions like diabetes or Parkinson’s disease.
If you are looking into this path, keep the following in mind:
- Program Availability: Not all fertility clinics or storage facilities have partnerships with research institutions.
- Specific Criteria: Research studies often maintain strict guidelines regarding the development stage, quality, and storage history of the embryos they accept.
- Finality: Once the embryos are transferred to a research laboratory and utilized, the decision is irreversible.
Consulting with your clinic and our legal team early helps you explore available research programs and confirm your consent is appropriately documented.
Discarding Unused Embryos
Choosing to thaw and discard unused embryos is a common and valid decision. For many, this path provides a practical sense of closure, allowing them to conclude their fertility treatment on their own timeline.
The process typically requires:
- Submitting a signed, notarized disposition authorization form to the clinic or cryobank.
- Obtaining written, mutual consent from both partners (if the embryos were created jointly).
- Authorizing laboratory staff to thaw the embryos, at which point they stop dividing and are disposed of as medical waste.
While legally straightforward, this choice can still be significant. Many clinics and matching organizations can connect you with specialized counselors to talk through these decisions.
Scheduling a Compassionate Transfer
For those who prefer not to donate their embryos but want an alternative to standard laboratory discard, a compassionate transfer provides another option.
A compassionate transfer (often called compassionate disposition) is a clinical procedure where embryos are transferred into the uterus at a specific point in the menstrual cycle when pregnancy is biologically impossible (typically after ovulation has passed).
This allows the embryos to dissolve naturally within the body, providing a private alternative to clinical disposal methods. If this option sounds right for you, we recommend speaking to your clinical team and our attorneys to verify your clinic’s protocols can accommodate the procedure.
The Importance of an Embryo Disposition Agreement
Regardless of the option you choose, establishing a legally binding embryo disposition agreement is an important protective step. These agreements do more than record your preferences. They create a legally recognized plan that outlines your intentions, resolves ambiguities, and limits potential disputes if circumstances shift.
To help you manage the planning process, here are direct answers to common legal questions regarding embryo storage and disposition:
When Should Intended Parents Start Discussing Future Plans for Stored Embryos?
Discussing embryo disposition before starting an IVF cycle is highly effective. Most fertility clinics require patients to complete intake forms detailing their preferences prior to fertilization. Having these discussions with your partner and your legal team early helps prevent rushed decisions down the road.
What Legal Documents Should Be Updated after Completing IVF?
Once your family is complete, we highly recommend updating several key documents:
- Embryo Disposition Agreements: To formally document your long-term choices once your immediate family-building goals are met.
- Wills and Trusts: To explicitly outline who has control or inheritance rights over your stored biological material in the event of death.
- Healthcare Proxies or Medical Powers of Attorney: To designate a trusted decision-maker authorized to manage stored embryos if you experience medical incapacity.
Can Embryo-Related Decisions Be Revisited in the Future?
Yes, embryo disposition decisions can generally be updated, provided both partners agree and the changes are documented in writing.
If you decide to adjust your selection, you will need to coordinate with your fertility clinic and our legal team to draft, sign, and notarize a new agreement before the clinic can implement your revised wishes.
