Donor Egg Guarantee

At Cryos, we understand that donor egg treatment is expensive, and having the reassurance that our frozen donor eggs will fertilize and develop into an embryo provides a higher level of confidence and security. As a patient of a Cryos Reference Clinic, or a clinic who has been trained in Cryos’ warming procedures, you will qualify for our Donor Egg Quality One Blastocyst Guarantee.

When a minimum of six (6) oocytes have been delivered to your clinic, Cryos guarantees at least one (1) blastocyst* or a pregnancy from embryos that have not reached the blastocyst stage. If this guarantee is not met, the six (6) oocytes will be replaced one time free of charge. Should the culture result in no blastocyst, but viable embryos less than the blastocyst stage are available, a transfer must take place for the guarantee to be in effect.

If a cycle does not result in one blastocyst or pregnancy, and the particular donor does not have another full cohort of oocytes available, the client will be offered the choice of either; all remaining eggs from the selected donor, or, a cohort from a different donor of their choice.

To qualify for this guarantee program the following criteria are required:

  • Semen parameters (on the day of sperm thaw) require > 5 million total motile sperm with a morphology of 2% or higher (Kruger strict criteria). Sperm will be checked at the time of egg warming/sperm thaw (prior to ICSI) to verify that it meets the required criteria.
  • No surgical procedures that require MESA, TESE or TESA.

Alternative guarantee options may be available, please see your clinic for details.

* A blastocyst is an embryo that has developed beyond the morula stage to include an inner cavity and two distinct cell types, trophoblast and an inner cell mass.
