Results and Success Rate of Female Fertility Preservation & Egg Freezing

Egg freezing is a female fertility preservation method in which a woman's unfertilized eggs are stored so that can be used to conceive at a later date, when natural conception would not be likely. The eggs can be preserved for women who are not ready to have a child at the moment. This method is also used for women who are at a risk of infertility because of medical reasons like cancer.

Frozen eggs can be stored for long years without much deterioration. When a woman is ready to use the eggs, they are warmed and fertilized with the sperm. Since, the aim is embryonic development and the developed eggs are transferred into the uterus to promote fertilization making it possible for the woman to conceive.

The process of egg freezing:
The process of egg freezing involves several steps. They are:

  1. Hormonal stimulation: Hormonal stimulation is given in the form of injections and this can be done by the patient herself. This will get the eggs ready. The injections may make the woman feel bloated up, but there are no severe side effects.
  2. Egg collection: The eggs are collected from the ovaries via an ultrasound probe, which is inserted into the vagina. A needle is run inside the probe and passes through the vaginal walls into both the ovaries. The eggs are separated from the ovary and the patient is given general anaesthesia.
  3. Vitrification: This process takes place in the laboratory where the eggs are frozen and is called vitrification. The eggs are rapidly frozen in a process where all fluids are extracted for prevention of ice crystal formation. After successful vitrification, the eggs can be stored for many years.

Success rate:
Egg freezing is a new procedure and it is too early to make a graph of its success rate. The age of the woman is an important factor which determines the success rate. According to a research, it has been found out that for women under the age of 35, one cycle of stimulation produces ten to twelve eggs out of which seven to nine can be used for storage. It is estimated that around 90% of the eggs would survive future warming, 50 to 80% of the eggs would successfully fertilize and 80 to 90% eggs would develop into embryos. The success rate is less in women above 35.

Female fertility preservation refers to the preservation of eggs to be used for fertilization at a later date. Egg freezing is a common fertility preservation process. Egg freezing cannot guarantee pregnancy and the birth of a healthy baby and the outcome of frozen eggs cannot be known for sure. If you wish to discuss about any specific problem, you can consult an IVF Specialist.
