Egg Freezing in India at IVF-ICSI CENTER, Delhi
What is Egg Freezing?
Egg freezing is a relatively new and experimental technique. A woman facing infertility due to medical or social reasons has the option of freezing her eggs for later use.
Who Could Benefit from Egg Freezing?
There are several groups of women who are candidates for egg freezing:
- Women who need to undergo chemotherapy or radiation therapy for cancer treatment
o Many of the chemotherapeutic drugs commonly used for cancers such as breast and colon are toxic to the ovaries
o Removing eggs from the ovaries prior to starting these treatments allows for the preservation of healthy eggs
o These eggs may be used many years in the future in order to achieve a pregnancy
- Women who require treatment with toxic agents due to auto-immune disease, stem cell transplants or bone marrow transplants
- Women who wish to delay the “biological clock”
o Single women
o Women wishing to delay pregnancy for personal and professional reasons
- Couples who are undergoing in vitro fertilization to overcome infertility, but who do not want to fertilize more eggs than they will utilize
o Eggs can then be thawed at some future date when they are ready to further expand their family
How is Egg Freezing Performed?
A woman wishing to freeze her eggs are given medications to stimulate multiple eggs. This medication stimulates the ovaries to produce several eggs or more. These eggs are then collected from her ovaries using a minor surgical technique known as transvaginal oocyte retrieval. This procedure is performed under light anesthesia, and no incision is required. Eggs are then rapidly cooled and frozen in liquid nitrogen for long term storage.

What is vitrification?
Vitrification comes from the Latin meaning “to turn into glass.” in this process eggs are rapidly cooled at a rapid rate. This rapid cooling prevents the formation of ice crystals within the egg. Ice crystals need to be avoided as they often damage the egg when it is subsequently thawed. The resulting frozen egg looks glass-like, hence the term “vitrification.”Ice crystals once formed damage the cytoplasm when the egg is subsequently thawed
Is Egg Freezing Safe?
The risk of abnormalities to babies born after vitrification is not increased . While this technology is relatively new, recent studies have been reassuring. In one study of 200 children born following egg freezing, the rate of birth defects (3.5%) which is no higher than the rate found in the general population.
How Long can Eggs be Frozen?
Once the eggs are frozen, they are essentially in a state of “suspended animation.” They do not age. the frozen eggs can remain in this quiscent stage of suspended animation after vitrification for unlimited period of time & still viable on thawing .
When Does a Woman’s Fertility Begin to Decline?
Fertility begins to decline in the late 20’s. This decline is relatively slow until approximately age 35 when the no. of eggs reserved in the ovaries falls steepily. By age of 38 years, the rate of fertility loss begins to accelerate, and continues to do so until the mid 40’s, when the chance of pregnancy declines significantly.

How Does Egg Freezing “Beat” the Biological Clock?
Frozen eggs are suspended at the age of the woman at the time the eggs were removed and preserved. The risk of birth defects such as Down Syndrome increase as a woman ages. Freezing eggs allows a woman to “put the brakes” on the risk of such birth defects. The eggs, in essence, do not age. They remain at the age that the woman was at the time of their removal from her body. While a woman may return years later to use her frozen eggs, there will be no increase in risk to the resulting baby, as these eggs have been “suspended” at that younger age.
