Why do women freeze eggs and what is it for?
0 (0)

Egg freezing, technically known as oocyte vitrification, is a procedure that preserves a woman’s fertility by cryopreserving her eggs. The eggs are retrieved, vitrified (an ultra-rapid freezing method) and stored in liquid nitrogen at extremely low temperatures, maintaining their viability for years.

Why are eggs frozen?

There are several reasons why a woman may choose to freeze her eggs. These include medical and social reasons:

  • Cancer treatment: chemotherapy and radiation therapy can affect fertility, so freezing eggs before treatment preserves the possibility of having children in the future.
  • Surgery that affects ovarian reserve: some gynecological surgeries can damage the ovaries and reduce ovarian reserve.
  • Autoimmune diseases: some autoimmune diseases can affect fertility.
  • Endometriosis: endometriosis can decrease ovarian reserve and compromise egg quality.
  • Postponing childbearing: women who wish to delay childbearing for professional, personal or educational reasons can freeze their eggs to preserve their fertility at a younger age.
  • Absence of a partner: single women who wish to have children in the future may choose to freeze their eggs.
  • Fertility preservation for other reasons: some women may choose to freeze their eggs as a preventive measure against the natural decline in fertility with age.

What is egg freezing for?

Egg freezing is used for the following purposes:

  • Preserve fertility: it offers the possibility of having biological children in the future, when circumstances are more favorable.
  • Increase the chances of success in fertility treatments: in some cases, egg freezing can improve IVF success rates, since it allows for a greater number of good quality eggs to be available.
  • Avoiding egg donation: Egg freezing allows women to use their own eggs in the future, avoiding the need for egg donation.
  • Provide peace of mind and control over fertility: it gives women more control over their reproductive future and reduces the social and biological pressure associated with age and fertility.

Egg freezing is a safe and effective technique that has revolutionized reproductive medicine. If you are considering freezing your eggs, it is important to consult with a fertility specialist to learn about the procedure, risks, benefits and costs. The doctor will evaluate your individual situation and help you make the best decision for your reproductive future.
