What is egg freezing
Egg freezing also referred by scientist as to the Oocyte Cryopreservation is a technique which lets women freeze their eggs and store them until they decide to use them for reproduction purposes. This process gives women the ability to stop the ticking of the family clock for some time and letting them pursue education and careers putting aside worries about not being able to have kids in the future.
What does egg freezing involve and who is it for
Egg freezing involves extracting the eggs from woman’s womb, then the eggs are frozen and stored. In the future when a woman decides she wants to have kids the eggs can be thawed, fertilized and transferred to the uterus as embryos.
Egg freezing is especially for women suffering from cancer and they did not undergo chemotherapy or radiotherapy yet and want to preserve the possibility of having kids in the future. It is also an option for people who are against freezing embryos because of religious or personal beliefs. This way they are able to create only the amount of embryos they want to use and not waste any. It is also a procedure aimed at women which want to pursue other goals in life like education or career and they want to postpone motherhood not letting their eggs loose quality with time. Also women with history of early menopause in the family can use egg freezing to make sure their eggs are safe.
The process of egg retrieval is similar to IVF in that it involves several weeks of hormone injections for stimulating the ovaries. When the eggs become mature they are retrieved from the woman’s body using transvaginal oocyte retrieval. The eggs are being frozen immediately after this process.
Freezing of the eggs is made using either a slow-cooling method or the new flash-freezing method called vitrification – much faster but more cryoprotectants are needed.
