Cryopreservation

Egg and Ovarian tissue Cryopreservation The first baby born from a frozen - thawed egg after fertilization in the laboratory under assisted reproduction was reported in 1986. However, despite the great importance of this scientific breakthrough, the success rate was so low that the freezing of eggs in [...]

Sperm cryopreservation Sperm cryopreservation is performed with the use of cryoprotectants which aim to protect the various cell structures of the sperm from the drastic change in temperature. The cryopreserved samples are kept in liquid nitrogen at -196 °C and can be maintained indefinitely in this temperature. The [...]

Embryo cryopreservation The first pregnancy from cryopreserved human embryos was reported in 1983. The freezing of embryos is now a routine procedure in most modern laboratories and thousands of IVF pregnancies have been achieved following freezing – thawing cycles. This technique offers two significant advantages: It reduces [...]

Cryopreservation - General Information Since 1983 when the first pregnancy with cryopreserved embryos was achieved, the progress of cryogenics has been rapid, thus allowing today the cryopreservation of both embryos and gametes (ova - spermatozoa). The development of cryobiology has helped to: reduce cases of multiple pregnancies [...]
