The process of freezing the extra embryos and then using it later is called embryo cryopreservation. This process can be useful during the in vitro fertilization. The reasons for embryo cryopreservation can be different Some can do that to use the stored embryos in the other pregnancy later. These embryos can be saved, donated to those who need or can be used for research processes. Some times when there is a high number of embryos then the better option is to eliminate those extra embryos. These can also be used in the IVF process. If the process fails the first time then the second time the embryos can be used
The embryos are stored under special conditions inside the laboratory. A liquid called cryoprotective agents is used for the protection of the embryos. The procedure used basically for the preservation of the embryos is slow programmable freezing and vitrification.
In the slow programmable process, the embryos are freeze gradually, in stages. The cryoprotective agents are added to the embryos in expanding qualities. At that point, the incipient organisms are gradually cooled more than two hours in a machine that brings down the temperature step by step. When solidified, the fetuses are put away in fluid nitrogen at - -196.1° Celsius.
On the other hand, Vitrification is a quick solidifying procedure that utilizes a lot of higher qualities of cryoprotective agents. The specialist initially blends the cryoprotective agents with the embryos using this technique. CPAs that are exceptionally solid can likewise hurt the cell. To keep this, the incipient organisms are immediately put into the fluid nitrogen. This procedure transforms them into a nearly strong state, similar to glass.
The embryos are usually frozen for the time duration of one to six-day and these embryos can be melted when there is such requirement. The normal water balance can be maintained maintain by using the special fluids to remove the agents in the embryos.
When they are solidified, the embryos are put away in fixed fluid nitrogen coolers. It can be there for any number of years. No certain time limit is still known n for how long the embryos stored are safe for use.
There are no risk factors involve in this process. The embryo storage does not have any negative impact on the upcoming baby. The babies born through this process areas healthy and defect-free ad that of normal ones. Numerous children have been conceived from developing lives by the embryo cryopreservation process. A few children have been conceived from embryos solidified for over 10 years. IVF programs with great cryopreservation strategies have a similar pregnancy rate with fresh ones.
Embryo cryopreservation can be utilized by any woman; however, this process can be more useful for women undergoing the following conditions the women with hereditary issues of ovarian sensitivities, the individuals who are expected to experience chemotherapy, and the individuals who take drugs that influence fertility. This process can be best suited for the women who are advancing towards mature age and they are still not ready for the baby can use the embryo preservation process to later use those embryos when they want to get pregnant.
