Egg Freezing

Fertility Preservation 300x200Individuals may choose to freeze their eggs for a number of reasons. The procedure was originally offered to people undergoing cancer treatment. In the event of infertility following treatment, with their eggs frozen, individuals could still try and build a family. These days, many are choosing to freeze their eggs to insure against fertility for other reasons, such as a focus on their career, the desire to wait until they’ve found the right partner, genetic reasons limiting fertility or if an individual is undergoing sex reassignment surgery or hormone therapy.

One of the methods used to freeze oocytes (egg cells) is vitrification.

This concept is based upon the idea that if the cell is dehydrated to a certain degree and then cooled fast enough, everything will “freeze” in place and damage will not have time to occur to the egg cells.

With vitrification, the solution containing the oocyte is cooled so rapidly it forms an instant glass-like structure, meaning water molecules don’t have the chance to form ice crystals that could potentially damage the egg cells.


What is Involved?

If you are interested in egg freezing you will first meet with a specialist, who will make sure you are medically healthy. A fertility coordinator will explain the process, medication and any potential risks or side effects of treatment if you decide to go ahead.

The IVF for Egg Freezing treatment cycle generally follows these stages:

  • Pre-treatment tests and preparation.
  • IVF treatment information and discussion.
  • Follicle growth treatment – fertility medications are used to stimulate the ovaries and promote the growth of follicles containing the eggs.
  • Monitoring of follicle growth – developing follicles are monitored with ultrasound and/or blood tests to control their size and quantity.
  • Egg collection – once follicles are large enough, they’re carefully emptied to collect the eggs. This procedure is performed by the treating specialist after the patient has been given a general anaesthetic or light sedation.
  • Vitrification – eggs are frozen and placed in storage in liquid nitrogen.
