What is Embryo Kryoconzervace?

Embryo cryoconzervace is a process of refining fertilized eggs for possible implantation; This is done for various reasons. The embryos are frozen and stored at extremely low temperatures until they are needed. While the embryo cryoconzervation can be a good guarantee for those who want to maintain their possibilities of fertility, freezing and subsequent defrosting of the nurses of fertilization can significantly reduce their viability. Typically, each harvested egg is fertilized to form an embryo. This increases the likelihood of creating several healthy embryos viable for transplantation. Because only so many embryos can be implanted at a time, often it means that it has left one or more fertilized eggs; The remaining ones who are often preserved for later use.

In other cases, the embryos are created with the only purpose of their freezing. Those with health problems that can affect their fertibility later in life may decide to be embryo cryoconzervace to makeShe had a chance or the possibility to have a biological child. While fresh embryos provide a better chance of transporting a child to care, frozen embryos can reduce the amount of IVF cycles that a woman has to undergo. Since these cycles are often painful and exhausting, the Embryo cryoconzervation can be a good choice.

one to five days after fertilization of eggs with sperm, can be tested for quality and then frozen. Healthy embryos are mixed with a solution of cryoprotectant to prevent the development of ice and then placed in airtight bottles. The bottles are then slowly cool to -400 ° Fahrenheit (-196 ° Celsius); The frost process takes several hours. Once the desired temperature is reached, the embryos are stored in a liquid nitrogen, where they can remain frozen up to 10 years.

Embryos are almost always frozen in doses. The specialist of patients and fertility usually discusses how many embryos will be implanted in the futureI before they undergo an embryo cryoconzervation. In this way, only the embryos to be implanted should be pulled out. Once the embryos are needed, they are thawed, which may take less than an hour. The embryos are cleaned to remove the cryoprotectant solution and then implant.

Each phase of embryo cryoconzervation can lead to the destruction of the embryo. Although the embryo is still viable after freezing and defrosting, it is significantly less healthy than fertilized eggs that did not install the embryo of the cryoconzervation. Usually only 32% of implantation procedures with previously frozen embryos lead to live birth. Although this figure is relatively low, many women were able to give birth to a biological child using IVF and embryo cryoconzerva.
