What happens to unused IVF embryos?
The decision you will face
Most people who complete IVF have embryos remaining. The options are generally: continue storing them, donate them to another couple, donate them for research, or allow them to perish.
There is no correct answer, and people who have thought about it in advance generally find the decision easier than those confronted with it unexpectedly.
Settle this before you start, in writing
Ask your clinic, before your first cycle:
- What is the storage duration, and the cost per year?
- What happens if I stop paying storage fees?
- What happens if I move city or country?
- What happens if the clinic closes?
- What happens in the event of separation, divorce, or the death of either partner?
- What consent do you require, and can it be changed later?
Get the answers in writing. These questions are uncomfortable and easy to defer, and the situations they cover are not rare.
That clinic-closure question is not hypothetical: departmental guidance in India has addressed the transfer of cryopreserved embryos between clinics when a clinic closes, which indicates it happens.
Storage
Embryos are stored in liquid nitrogen and remain viable for many years. Blastocyst cryosurvival benchmarks from the Vienna Consensus are competency at least 90%, benchmark at least 99% — ask your clinic for their own figure.
Storage requires ongoing consent and ongoing payment. Both are conditions people forget about years later.
Donation to another couple
Where permitted, this allows another person or couple to attempt pregnancy using your embryos. It raises questions worth thinking through: what a resulting child might be entitled to know, what you would want to know, and how you would feel about a genetic sibling being raised elsewhere.
Counselling is generally required, and is worth using rather than treating as a formality.
Donation to research
Embryos are used in research and are not transferred to anyone. What research is permitted is governed by regulation.
Allowing embryos to perish
A legitimate choice that many people make. Clinics can usually accommodate a request about how this is done, and some people find a small acknowledgement helpful.
The regulatory position in India
Embryo storage, donation and disposal are governed by the ART (Regulation) Act 2021. Clinics must be registered, and there are requirements covering consent and records.
Ask your clinic what the Act requires of them and what your options are under it. This page describes the general framework rather than legal advice — confirm specifics with your clinic.
The emotional part
Many people are surprised by how difficult this decision feels, including those who were clear about it beforehand. Feeling more attached to stored embryos than you expected is common and does not mean you decided wrongly.
Take the time. There is rarely urgency beyond the storage renewal date.

Frequently Asked Questions
What can I do with my unused frozen IVF embryos?▾
You have 5 options: (1) Continue storing with annual fees; (2) Use for another pregnancy via FET; (3) Donate anonymously to another infertile couple (permitted under India's ART Act 2021); (4) Donate for ICMR-approved medical research; (5) Discontinue storage and allow to perish. ASRM recommends discussing and documenting preferences before starting IVF, not after.
How long can IVF embryos be stored in India?▾
Under the ICMR ART (Regulation) Act 2021, embryos can be stored for up to 10 years, extendable with written consent from both parties. Annual consent renewal and storage fee payment is required. Storage costs Rs 15,000-25,000 per year at most Indian fertility clinics.
Can I donate my IVF embryos to another couple in India?▾
Yes -- embryo donation is legal and regulated in India under the ART Act 2021. Donation must be anonymous (clinic-mediated). Both partners must give written consent. The donating couple permanently relinquishes all legal rights and parental responsibilities. A couple can donate to a maximum of 3 other couples.
What happens to embryos if the couple separates?▾
Written disposition directives completed before starting IVF specify what happens in case of separation, death, or incapacity. Both gamete providers must consent to any embryo use -- without dual consent, the embryo bank cannot act. Courts in multiple countries have been asked to resolve embryo disputes following separation. Always document your wishes formally with your clinic from the start.
