Egg freezing or embryo freezing? Differences, costs and questions to ask
Thinking about the future does not mean having to settle every question today. You can explore alternatives and consider what fits your life at this moment.
The short answer
Egg freezing preserves unfertilized reproductive cells. Embryo freezing requires eggs to be fertilized first using partner or donor sperm. The choice depends on your medical circumstances and reproductive decisions. Both options require assessment, consent and storage arrangements, and neither can guarantee a future pregnancy.
The main difference is when fertilization takes place
| Question | Eggs | Embryos |
|---|---|---|
| What is stored? | Unfertilized eggs. | Embryos created in a laboratory. |
| Is sperm needed now? | Not to freeze the eggs. | Yes, to fertilize the eggs. |
| What happens when they are used? | Thawing, fertilization, embryo development and assessment for transfer. | Thawing and assessment for transfer. |
| What must be agreed? | Future use, storage and consent. | Future use, storage and consent from the relevant parties. |

What should you consider before deciding?
Your medical situation
The age at which eggs are collected and the expected ovarian response are part of the assessment. The number of eggs recovered, their maturity and subsequent development cannot be guaranteed in advance.
Your personal decisions
Ask what choosing a sperm source now would involve, how consent is documented and what alternatives exist if your plans change. Your decision does not have to follow someone else’s preferences.

Frequently asked questions
Do I need a partner to freeze my eggs?
Sperm is not needed to store unfertilized eggs. Medical assessment and consent are reviewed before starting.
Does embryo freezing always offer a better chance?
There is no universal answer. Prognosis depends on the age and quality of the eggs, embryo development and other individual factors.
Does the initial price cover all future treatment?
Do not assume it does. Request separate details for storage, thawing, fertilization when needed, preparation and transfer.
Are the six included months the maximum storage period?
They are the storage period included in ViaFERT’s published price. Continued storage is subject to the agreement, renewals and applicable consent.
