    Furthermore, Cryos beats the industry standards with a blastocyst rate of 47%. In fact, our percentage says that anyone purchasing six of our donor eggs will typically have results of one blastocyst or a pregnancy from embryos transferred on day 5.

    And to assure you that Cryos donor eggs will work for you, we offer you a donor egg guarantee, when ordering at least 6 eggs from one of our donors.
