Surrogacy With Frozen Embryos

Frozen Embryo : Surrogacy

Surrogacy arrangements and egg freezing are increasingly common processes with celebrities such as Kim Kardashian West and Kanye West, Andy Cohen, and Elton John speaking openly about their experiences. Yet despite the increasing number of children born through surrogacy, this path to parenthood is far from simple.

Egg Freezing

In 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.

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.

This breakthrough in fertility preservation allows pregnant women to preserve their reproductive tissue and bank healthy eggs before they undergo any medical treatments that could affect their fertility.

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).

Transporting embryos

For Instance ; If you are an intended parent who lives internationally and wants to use surrogacy in California , then the most difficult hurdle is freezing your embryos.

California isn’t the most exciting place, and it can take a long time to get to your desired fertility clinic in California. Embryo transport is usually done by plane. Two processes are used to freeze eggs and embryos from egg donation providers: vitrification and slow freezing.Because it is more cost-effective and efficient, most fertility clinics opt for vitrification.

Embryos are kept in liquid nitrogen-filled tanks when they are in storage. Some clinics circumvent this restriction by using a retention gel in their shipping containers. The foam absorbs some liquid nitrogen and keeps it inside the sealed crate as vapor. This does not violate the liquid nitrogen regulation planes must follow.

The embryos can be kept frozen in the shipping container for up to several days. It can sometimes last up to a week. This is enough time to transport the eggs and embryos from egg donation to the appropriate fertility clinic. The clinic then quickly unloads the patients and places them in their storage tanks. Once the embryos are properly stored, the intended parents will be able to find a surrogate for the process.


Vitrification has a 99 % survival rate, making it the best egg freezing method when compared to traditional freezing methods which only have around 55% of egg survival rates. This breakthrough in fertility preservation allows women who are interested in reproductive tissue preservation to save healthy eggs before they undergo any medical treatments that could affect their fertility.


The following are ideal candidates:

  • Women who are healthy and want to keep their fertility.
  • Donating eggs to a friend, family member or stranger.
  • Before any procedure or surgery that could kill some eggs (removing an egg cyst, a fibroid, etc.)
  • Patients with cancer who are about to receive chemotherapy or radiation treatment.
