Egg FreezingIn vitro fertilization isn’t the only option for fertility treatment. When traditional methods fail, there are many options available such as egg freezing with surrogacy. Understanding how these assisted reproductive methods work will help you make the right decisions for your particular situation.A woman can preserve her fertility by freezing eggs. After 35 years of age, biologically speaking, eggs become less fertile. A woman can preserve eggs of high quality until the time she is ready for her family by harvesting eggs early and storing them properly.Women who want to preserve their fertility at the best time for their eggs can consider egg freezing. Women should freeze their eggs by age 35 or in their 20s. However, there is no age limit. It all depends on how old the woman is and if eggs can be obtained from her ovaries.There are many reasons women choose to freeze eggs, including for career goals, relationships, and medical concerns. Whatever the reason egg freezing is chosen, it can give women peace of mind as they can concentrate on other areas of life without having to sacrifice their ability to have children in future.
Frozen embryo transfer For Surrogacy
Frozen embryo transfer (FET), is the use of thawed embryos from a previous IVF cycle for Egg Donor, and the transfer of the embryo to the uterus or surrogate. To have a surrogate, they must undergo a Frozen Embryo Transfer Cycle. Before the procedure, the surrogate will need to meet with a specialist to confirm that they are suitable for the surrogacy program. A fertility coordinator will also ask the surrogate to attend an information session. They will also be informed about the treatment they will receive (e.g. They will be informed about the type of treatment they will receive, the risks and implications for pregnancy, lifestyle recommendations and any other requirements).
How it Works
Vitrification is a flash freezing method prevents the formation ice crystals.
Eggs are frozen at a temperature of 98.6°F (37°C), and then brought down to -320°F (-196°C) immediately. The cells are dehydrated prior to freezing. Protectants are used to remove as much water from the cells as possible. This prevents harmful ice crystals forming. The survival rates for vitrification are up to 99 %, compared to the 55% of traditional freezing methods. This is because combination of cryoprotectants with flash freezing/thawing has a greater chance of safely restoring cells to their original condition.The largest cell in the human body, eggs, is comprised of two parts: the zona (a glycoprotein envelope), and the ooplasm, which contains the nucleus and mitochondria. They are vulnerable to ice crystal formation because they are the largest cells of the body.The largest cell in the human body, eggs, is comprised of two parts: the zona (a glycoprotein envelope), and the ooplasm, which contains the nucleus and mitochondria.
