New research supports long-held beliefs that length of cryostorage period does not impact embryo survival

A recent article in the Journal of Assisted Reproduction and Genetics concluded that storage time did not influence the survival and pregnancy outcomes of slow-frozen early cleavage human embryos. The developmental potential of cryopreserved human embryos with different storage times does not appear to have a negative influence on further development.
