Egg Storage/Banking

Egg freezing is a fertility treatment that collects eggs from the ovaries and stores them for future use by freezing them with a technique called vitrification. Women choose egg freezing if they are delaying having children until they are older or if they are going to have medical treatment that could affect their eggs.

To have egg freezing you need to have IVF treatment to grow, collect and store your eggs. These eggs can be thawed out (or warmed) in the future when you are ready for pregnancy and fertilized with sperm to produce embryos. Your embryos are then gently placed inside the prepared womb (uterus) to give a chance of pregnancy. Egg freezing effectively suspends the egg in time, to preserve fertility, until later when you wish a pregnancy.

Who might need egg freezing?

Egg freezing is becoming a popular choice for women who are delaying having a family for a variety of reasons. Many women are not currently in a relationship with someone, or are choosing to focus on work or studies. Some other women are simply not ready for a family now, but know that when they will be ready in the future if their age is over 40, they will have a much lower chance of having a baby.

Other women have medical conditions or need to have medical treatments that could remove or damage their store of eggs. As women are born with all the eggs they will ever have, these women will never be able to recover or replace these lost or damaged eggs. Egg freezing is a way to preserve their fertility for the future. Examples of these medical conditions and treatments are;

  • cancer treatments such as surgery, chemotherapy or pelvic radiotherapy that are likely to lead to partial or complete egg loss or damage
  • surgery to remove the ovaries, e.g. endometriosis or ovarian cysts
  • women with a family history of early menopause (stopping your periods before the age of 40)
  • other rare medical conditions and drug treatments that might affect a woman’s eggs

What is involved in egg freezing?

STEP ONE is a free nurse consultation with one of our fertility nurses.

You will have the AMH blood test to assess your current egg levels along with some other tests. Find out more about the process with information tailored to your situation and have your questions answered.


– Doctors appointment.  The doctor will review your situation in detail and go through the options you have. Egg freezing has different success rates for everyone and it is important that you understand what the treatment will mean for you.


– Preparing for treatment Before IVF treatment you will need to have some routine blood tests and complete consent forms. It is also helpful to understand the process clearly, so we ask you to attend a free IVF nurse discussion to go through your treatment in detail. A free appointment with our clinic counsellors is also available and recommended for everyone considering this treatment.


– Having your treatment to collect and free eggs. IVF treatment involves growing eggs by using fertility injections for between 8-14 days, followed by the egg collection procedure. See information sheet on IVF (LC63).


– Having your treatment to thaw your eggs and transfer your embryo. When you are ready to try for a pregnancy you will have the treatment of preparing you for an embryo transfer and having the eggs thawed out and fertilised with sperm.

How well does egg freezing work?

Egg freezing does work to create babies, however only a small number of women have been through this procedure worldwide. At the moment it is difficult to give reliable success rates. Generally, the younger a woman is at egg freezing, the better her chance of a pregnancy from the eggs will be. If good quality eggs are frozen an average of 75% will survive the thawing process. Fertilisation then occurs in 60-70% of these thawed eggs. This means that it is best to freeze ten or more eggs in one treatment cycle to have a reasonable chance of a pregnancy in the future.

Worldwide, data at present shows that babies born from frozen eggs have no increase in abnormalities or birth defects.

How long is it safe to store frozen eggs?

The length of time that the eggs are frozen does not seem to affect the success rate of achieving a pregnancy or healthy birth. We store both embryos and eggs for five years and can extend this time period when required.

How much does egg freezing cost?

There are several costs to consider.

  • The initial cost to see the doctor and have the necessary investigations
  • The IVF procedure and drugs needed to collect and store the eggs
  • Annual storage fees for your frozen eggs
  • The thawing procedure and embryo transfer treatment when you are ready for pregnancy

These costs are different for everyone and we can advise you of the likely costs at the present time in the clinic, after your assessments.

What are the risks of egg freezing?

There are the risks of going through an IVF treatment to consider (see info sheet LC63). Also, as egg freezing is still a relatively new technique not all eggs will survive the freezing and thawing process or become fertilised by sperm.

Will there be any follow up by clinic staff?

We understand that this can be a difficult and emotional time for you.  Should you wish to access any supportive counselling regarding this treatment please contact our reception staff at either office to make an appointment.

The clinic will write to you annually to check that you are well and find out if you wish to keep the eggs in storage. The eggs are subject to an annual storage fee, currently $2,000.00 TTD but this could increase over time, for the upkeep of the eggs storage solution (liquid nitrogen) and for safe monitoring.

On-going contact with the clinic is encouraged.  It is THE PATIENTS responsibility to contact the clinic if ANY contact details have changed i.e. change of address or phone number. If the clinic is unable to easily contact you, this is considered abandonment and your case will be forwarded to the Internal Ethics Committee for review and possible disposal.
