Freezing embryos as an infertility treatment offers you a great value for your money. The technology used in freezing embryos significantly increases the likelihood of pregnancy per IVF cycle, making IVF by far the most successful and efficient form of assisted reproductive technology currently available to patients. Every couple facing fertility issues should read this for a more complete explanation of this sometimes-confusing topic.
Once embryos have undergone the cryopreservation process (using cryo-vitrification), they are stored in secure containers under liquid nitrogen. Under these conditions (a temperature of -321°F), essentially no biological or physiological activity can occur until thawed. At one time, births from frozen embryos that had been stored for over 8 years made headlines, but today, births from embryos stored 10 years or longer are not even considered newsworthy.
