Egg Freezing


Egg Freezing


A premier programme gives you direct access to experienced and highly skilled fertility doctors and embryologists to make your treatment as personalised and successful as possible.


Introduction

Egg freezing, also called oocyte vitrification, is an advanced method for preserving women’s fertility. As all we know, women’s fertility goes down when they are getting older. Especially when the age beyonds 35, the fertility will drop dramatically. If women do not want to have a baby right now and regret later, the best thing to do is to preserve their fertility as soon as possible. Earlier to freeze their eggs, higher chance to have a baby in the future. 

Freezing eggs is the most difficult technique in the IVF field, because the eggs are the largest cells in the human body and contains a lot of water. In order to freeze eggs and preserve them properly, it needs to remove the water from inside the eggs and replace with the right amount of cryoprotectants. This process is the most difficult part in the embryology field. Without a lot of experience and correct freezing protocol, a lot of ice could be formed inside the eggs. The ice is extremely detrimental to the viability of the eggs, as when we thaw them the ice will destroy the structure of the cytoplasm and damage the chromosomes. 

For the best chance of your future, choosing the right clinic for egg freezing is very important. Before you decide to go with any clinics, you must ask some same questions: 1. how many eggs have they frozen and cycles have they done? 2. What is the results from thawed frozen eggs and how many thawing cycles have they done? 3. How many babies have been born from thawed frozen eggs?

Egg freezing process

The whole egg freezing treatment cycle includes 5 steps, and takes around 2-3 weeks to complete:

Step 1 Initial Consultation: The first step is to book your appointment for an initial consultation with a fertility specialist to ask all questions and learn about your fertility before making a decision.

Step 2 Fertility Check-Up: Once you decide to go ahead, you can book an appointment for check-up of your fertility. During the appointment, you will be asked for an ultrasound scan to check your pelvic anatomy, notably your ovaries and uterus. You will also be asked to do some blood tests, including hormone levels to assess your ovarian function. According to the results, our specialist will make a personalised treatment plan for you for ovarian stimulation, to safely and effectively result in the best number of eggs to freeze for you. After this appointment our nursing team will help you to sign relevant consents as well as teach you the correct use of the prescribed medications.

Step 3 Medications: After the consents are signed and you are ready, our nursing team will tell you when to start injection of medications typically daily for two weeks. During this time, you will need to visit the clinic 3-5 times for scan and blood tests to monitor your progress and adjust your medications if necessary. When a sufficient number and size of follicles are seen by scan in your ovaries, you will then be advised to adiminister another injection, called "trigger injection" about 36 hours before egg collection is scheduled. The trigger injection causes the final maturation of your eggs as well as loosen their attached to the follicle wall, permitting easier aspiration at the egg collection.

Step 4 Egg Collection: You will be sedated for 20-30 minutes while your eggs are collected by one of our fertility specialist doctors. One or two hours later you can be accompanied home to rest and most women have no major problems to return back to normal life or work next day. We emphasise that you should have someone to accompany you home after egg collection.

Step 5 Egg Freezing Process: After egg collection, eggs will be cultured for a couple of hours in the laboratory before we start to freeze the mature eggs, usually 80-90% of the eggs collected. All your mature eggs will be assessed and frozen very carefully using the technique called vitrification by our skilled embryologists. After freezing your eggs will be stored under -196 degree liquid nitrogen for long term storage.
