Embryo Freezing

Embryo freezing, also known as embryo cryopreservation, involves freezing embryos (fertilized eggs) for future use. You and a partner or donor can create embryos now to be used years later. In many cases, embryos left over from an IVF cycle are frozen so that they can be thawed and used in future cycles. In other cases, embryos are explicitly created for fertility preservation for those who are not yet ready to start a family.

Planning For A Future Embryo Transfer?

Embryo freezing creates embryos through IVF and preserves them for possible use in a future frozen embryo transfer cycle.

Embryo freezing and cryopreservation
Why it may be considered

When Embryo Freezing May Be Part Of Care

The decision depends on your IVF plan and future family-building goals.

01

After An IVF Cycle

Embryos not selected for the current transfer may be frozen for possible future use.

02

Planning Pregnancy Later

Embryos may be created and stored when a patient is not ready to attempt pregnancy now.

03

Before Medical Treatment

Embryo freezing may be considered before treatment that could affect future fertility.

What treatment involves

The Embryo Freezing Process

Embryo freezing is part of an IVF cycle and requires sperm to fertilize the retrieved eggs.

Step 01

Create Embryos Through IVF

Eggs are retrieved and fertilized with sperm in the laboratory to create embryos.

Step 02

Evaluate Embryo Development

The laboratory follows embryo development. Preimplantation genetic testing may be discussed when it is part of the treatment plan.

Step 03

Freeze And Store

Embryos selected for cryopreservation are frozen using vitrification and stored for possible future transfer.

Related care

Embryo Freezing And Egg Freezing Are Different

Embryo freezing requires fertilization with sperm before storage. Egg freezing preserves unfertilized eggs, so sperm is not required at the time of freezing.

Financial planning

Understand Your Options Before Treatment

The cost of fertility care depends on the treatment plan and services involved. AFMC can help you review fees, insurance benefits and available financial resources before treatment begins.

Common questions

Embryo Freezing FAQs

What is embryo freezing?

Embryo freezing, also called embryo cryopreservation, preserves embryos created through IVF so they may be considered for transfer in a future cycle.

Does embryo freezing require sperm?

Yes. Eggs must be fertilized with sperm to create embryos before they can be frozen. Egg freezing is the option that preserves eggs without fertilization.

How are embryos frozen?

Embryos selected for cryopreservation are typically frozen using vitrification, a rapid-freezing method, and then stored under controlled laboratory conditions.

Can embryos be tested before freezing?

Preimplantation genetic testing may be discussed as part of an IVF plan. Whether testing is appropriate depends on the patient’s circumstances and treatment goals.

Will every frozen embryo survive warming?

Embryo survival after warming varies with embryo development, cryopreservation and individual laboratory factors. Your care team can explain what is known about the embryos in your treatment plan.

What happens when I am ready to use a frozen embryo?

A future frozen embryo transfer cycle prepares the uterus for transfer. The selected embryo is warmed in the laboratory before the planned transfer.
