The process of egg freezing or oocyte cryopreservation involves the extraction of the eggs of a woman, freezing them and then storing them. This is a method to preserve the reproductive potential of women who are in their reproductive age. The first successful such attempt was made in 1986. The process has greatly improved through the ages with the success of eggs surviving the freezing process. The process is no longer in an experimental theory. The techniques that have led to an increase in the amount of gamete survival and potential fertilization have allowed women a much greater chance that what have been possible a decade ago. The seasoned professionals at ARC can help you with the process once you make up your mind.
Cryopreservation of eggs is considered for a variety of reasons in different persons:
These are some of the cases when eggs preservation comes in quite handy.
First of all, there would be some tests conducted to check the ovarian reserve. This is to make an estimation of the potential yield of the oocytes prior to the stimulation cycle. The assessment is very much necessary as it would also help to determine the required dosage and other criteria. The process takes a similar route like that of in vitro fertilisation. The process includes the use of injectable hormonal medicines, followed by the aspiration of the oocytes and the surrounding fluid through the vagina. The mature eggs are recognised under the microscope and cryopreserved by storing in liquid nitrogen.
When the woman wants to achieve pregnancy, the preserved eggs are placed into warming solution and assessed. The eggs which survive the process are fertilized by the process of intracytoplasmic sperm injection. The fertilised eggs are cultured and then placed in the embryo when ready. The success rate is about 4% - 12% at the present. The determining factors are the age of the woman at the time of freezing and the number of eggs. There have not been any risks that have been assessed as of yet. The eggs can be stored for about 4 years, though it has not been found that storing them for a long time can have adverse effects. However, the maternal age can have risks associated with the pregnancy, like diabetes and high blood pressure.
