Vitrification: the cold revolution

Vitrification is generally associated with delaying maternity. It involves preserving eggs at low temperatures so that they may be used in the future. This is, in itself, astounding since it enables gametes to be preserved by means of advanced and ultra-rapid cell freezing so that they may be used sometime in the future. The uses to which this technique may be put are so varied and numerous and have changed the work environment in the most prestigious of fertility clinics to such an extent that experts have no doubts about referring to vitrification as a ‘revolutionary’ procedure.
“We could say that cryopreservation is currently the most important aspect of any assisted reproduction clinic” assures Dr Jorge Ten, head of the Reproductive Biology Operational Unit at Instituto Bernabeu in Alicante. In the words of this expert, this technique “has changed enormously over the last 6 to 8 years”. Vitrification was initially carried out using “slow freezing techniques which caused cell damage” in the oocyte. This cell, “in the case of women, is the largest in the human body and has the greatest content in water. Therefore, when frozen, it produced poorer results due to the formation of ice crystals which damaged its structure”. The ice crystals which formed as a result of the aforementioned slow freezing and the high water content in the cell meant that survival rates were “between 20 and 30%. Almost no oocytes survived”.

Embryo transfer

Embryo transfer is the culmination of various assisted reproduction treatments: in-vitro fertilisation, egg donation, embryo adoption, use of cryopreserved embryos, and so on.
The embryo is transferred from the laboratory to its ultimate place of development, the mother’s uterus. […]
