Deciding What Happens to Your Remaining Embryos

Why are there embryos left to decide about?

Surplus embryos are a normal by-product of how IVF is now done. A single retrieval can produce several embryos, but clinics increasingly transfer just one at a time. Elective single-embryo transfer keeps pregnancy rates strong while sharply lowering the risk of twins or triplets, so a cycle that works often leaves the remaining embryos frozen for later 1Ref 1Practice Committees of ASRM and SART (2021).Guidance on the limits to the number of embryos to transfer: a committee opinion.That elective single-embryo transfer preserves pregnancy rates while reducing multiple gestation, so a successful IVF cycle commonly leaves surplus embryos in storage.2Ref 2Practice Committee of ASRM and SART (2022).Multiple gestation associated with infertility therapy: a committee opinion.That multiple gestation is the principal avoidable risk of infertility therapy, which is why a single embryo is usually transferred at a time, leaving remaining embryos frozen..

Having embryos left over is the expected result of transferring one at a time, not a sign that anything went wrong.

Because the embryos may have been created years earlier, the question of what to do with them can surface long after your family feels settled — after a birth, after you have decided you are done, or after a relationship changes. That distance is part of what makes it hard.

What can you do with stored embryos?

Stored embryos generally have five possible futures, and a clinic will not act on any of them without your written direction. You can take months or years to decide, and you can change course as long as the embryos remain in storage. The options are:

• Keep them frozen. Continue the plan by paying the annual embryo storage fees and revisiting the question later. What that cryostorage annual fee costs is covered separately.
• Donate to another person or couple. Sometimes called embryo donation or embryo adoption, this sends the embryos to someone else building a family, through a clinic program or agency with its own screening, counseling, and legal steps.
• Donate to research or training. The embryos are used for approved scientific study or to help train embryologists, and are never transferred to anyone.
• Thaw and respectfully discard. The embryos are thawed and allowed to stop developing. Some families mark this with a small ritual or choose a compassionate transfer, described below.
• Transfer them yourself later. If another child is still possible for you, keeping them for your own future transfer is simply continuing what you started.

Whether you originally chose freezing eggs vs. embryos changes only the details here, not the shape of the decision.

There is no medically right answer

No option here is the clinically correct one, because this is a decision about values rather than medicine. Shared decision-making frameworks used across healthcare — such as the AHRQ SHARE Approach — exist precisely for choices like this. That model walks through five steps: seeking your participation, helping you compare the options, assessing what you value and prefer, reaching a decision together, and later evaluating it 3Ref 3Agency for Healthcare Research and Quality (2020).The SHARE Approach.That the AHRQ SHARE Approach is a five-step shared decision-making model that weighs each option against the patient's own values and preferences — the framework for a values-based choice like embryo disposition..

Nothing forces this decision on a timeline; the embryos remain safely frozen while you think it through.

A fertility counselor can help you and your partner talk it through without pushing you toward any particular path. Their job is to surface what matters to you, not to supply the answer.

The questions the decision usually turns on

People usually find the decision hinges on a handful of personal questions rather than on any medical fact. How you feel about the embryos' genetic tie to you, your religious or moral beliefs about when life begins, whether you could accept another family raising a genetic sibling of your children, the ongoing cost of storage, and whether your family already feels complete all pull the choice in different directions.

There is no formula that resolves these. Two people who love each other and share the same embryos can weigh the same questions and land in different places, and that is normal. Naming which of these questions weighs most for you is often the whole work of the decision.

What the consent forms ask you to decide in advance

Before an IVF cycle, and again when embryos are frozen, the clinic's consent paperwork asks you to state what should happen to stored embryos under future contingencies. This is often called a disposition directive. It typically covers what happens if partners divorce or separate, if one partner dies, if both die, if you disagree with each other later, or if you stop paying storage fees and lose contact with the clinic.

It is worth revisiting that paperwork after any major life change, because an old directive can no longer reflect what you want. Directives also travel: if you are transferring embryos to another fertility clinic, the receiving clinic will have its own forms and its own storage terms.

If you and your partner disagree

When two people who created embryos together want different things, there is rarely a fast or obvious resolution, and the embryos stay frozen until it is settled. This is one of the situations the consent directive is meant to anticipate, but real life outruns paperwork, and feelings change after a birth, a loss, or a separation.

A fertility counselor or a trained mediator can help you talk through the impasse. Because the legal status of embryos varies from state to state and courts have not ruled consistently, independent legal advice for each person is worth seeking before anyone signs anything new. There is no medical harm in the embryos waiting while this is worked out.
