Embryo Cryopreservation

Embryo Cryopreservation

Embryo cryopreservation is the process of freezing and keeping embryos for use in the future. Extra embryos removed during IVF therapy can also be stored, or new embryos might be created solely for preservation. The embryos are utilized once they have thawed. Cryopreservation of embryos can play a significant role in IVF treatments.

Why Choose Embryo Cryopreservation?

As cryopreservation plays a significant role in IVF treatment processes it has many different benefits. As it is basically freezing your embryo for future use, many people might want to use embryo cryopreservation for different reasons including: 

  • They could think it's preferable than throwing the additional embryos.
  • If the first round of IVF is unsuccessful, a second chance at conception will be offered. The pair won't have to go through the egg pickup process again.
  • The couples will be able to use the embryos later to conceive a second child if they are successful in becoming parents.
  • The woman can keep embryos that could reduce or eliminate her chances of becoming pregnant before beginning therapies, such as those for cancer.
  • The embryos might be kept and given to someone else in a donor program.
  • The embryos could be kept and given out for scientific study.

What is the Procedure of Embryo Cryopreservation?

Water makes up the majority of a cell. When freezing embryos, the biggest worry is that ice will develop in the cells and between them. Ice crystals have the potential to damage the cell wall as well as the microscopic inside components.

The embryo needs to be safeguarded during the freezing procedure. Cryoprotective substances known as special fluids are used for this (CPAs). CPAs act as cellular "anti-freeze." Doctors utilize vitrification and slow programmed freezing, two distinct methods, to freeze and preserve embryos.

The slow-programmed freezing technique involves gradually freezing the embryos. The CPAs are introduced to the embryos in escalating strengths over 10 to 20 minutes. The embryos are then chilled in a device that drops the temperature gradually over the course of two hours. The embryos are kept in liquid nitrogen after being frozen at -321° Fahrenheit (-196.1° Celsius).

In vitrification, a type of fast freezing, the CPAs are combined with the embryos first and have much greater potencies. CPAs may also cause injury to the cell. To prevent this, liquid nitrogen is applied right away to the embryos. They become virtually solid, like glass, at this phase. It is impossible for ice to develop in this situation.
When necessary, the embryos are gradually defrosted. The CPAs are then extracted by soaking them in certain liquids which also restores the cell's normal water balance.

How Safe is Embryo Cryopreservation?

According to research, the newborn is unaffected by the freezing and thawing of embryos. Children born from frozen embryos do not have a higher chance of having birth abnormalities or other health issues than children born from fresh embryos.
