What is an Embryo Guarantee, and how does it work?

Starting IVF treatment using donor eggs is an exciting step, but it’s natural to have questions. For many, uncertainty around success rates and outcomes can feel overwhelming, and you might not know where to start. 

That’s where an Embryo Guarantee can make a world of difference. Having a clear promise can give you comfort and peace of mind in a process that can feel unpredictable.

In this blog, we’ll walk you through what an Embryo Guarantee actually means, how it works at Central Egg Bank and Australia Wide Egg Bank, and how it gives you the security you need to take the next step.

 

What is an Embryo Guarantee?

At Central Egg Bank, we offer a range of carefully designed programs with embryo guarantees to help support you throughout your fertility journey. Each of these includes an Embryo Guarantee, which promises you’ll get at least a certain number of high-quality embryos, known as blastocysts, from your cycle.

If the guaranteed number of blastocysts isn’t achieved and no pregnancy occurs, we’ll provide additional donor eggs at no extra cost (excluding shipping). A confirmed clinical pregnancy at 8 weeks is considered a successful outcome of the program, even if fewer blastocysts were created.

Every embryo must meet specific criteria to be deemed suitable for transfer. This is part of the embryologist’s role at your clinic, giving you the best chance of a successful outcome. The embryologists will communicate with you regarding your embryos and their progress, ensuring you feel informed, supported, and cared for.

 

What’s the difference between eggs, embryos, and blastocysts?

An egg, or oocyte, is the unfertilised cell from the ovary. After it’s fertilised by sperm, it becomes an embryo. 

When the embryo reaches a more developed stage, usually around the fifth day, it’s called a blastocyst. This is the stage most often used for embryo transfers because it offers the best chance of implantation.

 

Why do Embryo Guarantees matter?

Fertility treatment is an emotional, physical, and financial investment. Without an Embryo Guarantee in place, this can lead to more stress and unexpected costs.

Embryo Guarantees help provide reassurance, knowing that your donor egg provider has planned ahead to help you achieve the best possible outcome. Most importantly, they show the clinic or egg bank stands behind the quality of the donor eggs.

 

How our Embryo Guarantees work

We offer four premium donor egg programs, each with a blastocyst guarantee that varies depending on your chosen program. 

  • 8 Egg Program – $12,900 USD. This program includes eight eggs and guarantees at least two blastocysts.*
  • 10 Egg Program – $14,500 USD. Includes 10 eggs and also guarantees a minimum of two blastocysts.*
  • 12 Egg Program – $16,300 USD. Includes 12 eggs and guarantees at least three blastocysts.*
  • 14 Egg Program – $17,900 USD. This is our most comprehensive option with 14 eggs and a guarantee of four blastocysts.*

*T&Cs apply

 

How can we offer this guarantee?

Embryo guarantees are only possible when a program is built on quality, experience, and consistent results – this is what sets us apart. Our results speak for themselves:

  • Over 10,000 donor eggs have been thawed and used in Australian clinics through Central Egg Bank.
  • We have a high record of successful pregnancy rates, thanks to high-quality donor selection, expert embryology, and compassionate care at every step.
  • Every embryo must meet strict quality criteria, as outlined in the SART grading system, to be covered by the guarantee.

 

Accessible fertility options with Australia Wide Egg Bank

Australia Wide Egg Bank (AWEB) is our sister organisation, created to make donor eggs more accessible for families across Australia. Backed by over seven years of experience from Central Egg Bank, AWEB offers programs grounded in the same high standards of care and quality, with added flexibility to suit different needs and budgets.

With options that include either a high thaw survival rate or a guaranteed blastocyst embryo, AWEB’s programs are designed to offer peace of mind while remaining cost-effective: 

  • 6 Egg Program – $8,400 USD. This program guarantees a 90% thaw survival rate and at least five eggs after thawing.
  • 7 Egg Program – $10,200 USD. This includes a guarantee of one blastocyst embryo.
  • 8 Egg Program – $11,600 USD. Also includes a guarantee of one blastocyst, with a slightly higher number of eggs.

 

What should you consider before choosing an egg bank?

No two fertility journeys are the same, and when it comes to choosing a donor egg program, what works for one person may not be right for another. Practice varies between different egg banks and providers, so it’s important to choose a program that feels right for you. 

If you’re still deciding on what to do on your journey, here are a few things to keep in mind when comparing programs across different donor egg providers:

  • What’s actually guaranteed? Some programs guarantee a certain number of eggs, others promise a number of high-quality embryos (blastocysts), and some do both. Ensure you read each program’s details and understand the different offerings. 
  • What happens if the guarantee isn’t met? Policies vary between providers. For example, CEB will provide additional eggs to meet the patient guarantee at no extra cost (except shipping). However, not every egg bank offers this level of assurance. It’s important to know your chosen egg bank’s policy and costs.
  • What does your clinic support? Whether your clinic performs embryo transfers on Day 3 or Day 5 will affect how your guarantee applies. Our team can help you understand how this works in relation to your chosen program.

 

Ultimately, the right guarantee is the one that helps you feel informed, supported, and confident moving forward. Whether you’re drawn to a more comprehensive option with multiple embryos included, or a more flexible, affordable package, you deserve to feel in control of your next step.

Choosing to do IVF with donor eggs is a deeply personal decision – one that takes strength, clear thinking, and the right support. Central Egg Bank is committed to providing you with all three. Our embryo and thaw survival guarantees are one way we help take the guesswork out of your journey, giving you greater peace of mind and a clear path forward.
