title: [Cryopreservation of embryos--used for treatment of infertility by means of assisted reproductive techniques (ART)].
abstract: Freezing of the human embryos has been routinely used in the world for over 10 years in the treatment of infertility by the ART. Excessive fertilized oocytes and embryos can be frozen and preserved in the temperature of liquid nitrogen. The risk of multiple pregnancies is reduced and enhancement of pregnancy rates can be obtained owing to cryopreservation. The author presents theoretical principles of embryo freezing by slow cooling with 1, 2 propanediol and saccharose as a cryoprotectant.
