Oocyte cryopreservation:

Oocyte cryopreservation, also known as egg freezing, is a method used to preserve reproductive potential in women wherein the woman's eggs (oocytes) are harvested from the ovaries, frozen unfertilized and stored for later use. During IVF treatment, the frozen egg can be thawed, fertilised with sperm in a lab and implanted in the uterus.Indications of Cryopreservation

One is about to undergo treatment for cancer or any other illness that may affect fertility in future. Treatments like radiation or chemotherapy can harm fertility. Egg freezing before treatment can help one have biological children later.

One undergoes IVF and if the partner isn’t able to produce sufficient sperm on the day eggs are retrieved.

One can use frozen eggs to try to conceive a biological child with sperm from a donor.

Oocytecryopreservation:

The process is done in three stages – ovulation induction, egg retrieval and freezing.

Ovulationinduction

The mother, at the beginning of her menstrual cycle, will have to start synthetic hormones to stimulate the ovaries to produce multiple eggs.

When the follicles are ready for egg retrieval, trigger shot is given for the eggs to mature.

Eggretrieval

Egg retrieval is done under anaesthesia using transvaginal ultrasound, wherein an ultrasound probe is inserted into the vagina to identify the follicles. A needle guided through the vagina and into a follicle has an attached suction device which is used to remove the egg (or multiple eggs) from the follicle.

Freezing

Shortly after the eggs are harvested, they are frozen to be preserved for future use. in liquid nitrogen at the temperature of -196⁰C .
