Frozen Egg Donor Cycle
Frozen donor eggs, ready when you are
Eggs already retrieved, vitrified and stored — no cycle synchronization, a known number of eggs upfront, and safe shipping to your clinic worldwide.

Advantages
Advances in vitrification have made frozen donor eggs a flexible, predictable path to parenthood.
Why parents choose frozen donor eggs
No synchronization
No need to align the donor’s and recipient’s cycles.
Known egg count
Retrieval is already done, so you know how many eggs you have before starting.
Shorter timeline
The time from choosing a donor to embryo transfer can be shorter.
Lower cost per cycle
The cost per treatment cycle can be lower than with fresh eggs.
How It Works
From egg bank to embryo transfer
Four simple stages, fully coordinated by our team.
01
Choose your donor
Select from screened donors with frozen eggs in the Origen Egg Bank.
02
Vitrified & stored
Eggs are preserved by vitrification, an ultra-rapid freezing that protects their structure.
03
Shipped to your clinic
Secure cryogenic shipping to the IVF clinic in your country.
04
Thaw, fertilize, transfer
Eggs are thawed, fertilized and the embryo transferred to the recipient.

Fresh or Frozen?
A quick comparison
Process
Frozen: eggs ready to use, no synchronization.
Fresh: donor and recipient cycles aligned.
Timing
Frozen: quicker start to IVF.
Fresh: more planning required.
Eggs
Frozen: a fixed, known number.
Fresh: often a larger number of eggs.
What is vitrification?
Vitrification adds cryoprotectants to the eggs, followed by ultra-rapid cooling. This prevents ice-crystal formation and keeps the egg’s structure intact until it is thawed, fertilized and prepared for transfer.
Are success rates different from fresh eggs?
National live-birth rates with frozen donor eggs are currently somewhat lower than with fresh eggs, but freezing and thawing technology has improved significantly. Results also depend on the clinic performing the transfer.
What are the risks?
Medical risks mainly concern the donor during retrieval, such as rare ovarian hyperstimulation, infection or bleeding. Research shows the risk of birth defects with frozen donor eggs is minimal and comparable to other assisted reproduction methods.
How are the eggs shipped to my clinic?
In temperature-controlled dry shippers kept cold with liquid nitrogen, along safe and direct routes. Dewars are never X-rayed, and our support team is available around the clock during transport.
