Social freezing (oocyte freezing for later use)
Egg freezing/cryopreservation via vitrification is a relatively young method intended for women who plan to postpone their pregnancy for the future time.
The motives for the decision are mostly wish to finish university education and focus on professional development or currently not having a right partner to start a family with. Egg freezing via vitrification is also recommended for women before treatment for endometriosis or planned cancer treatment. We sometimes use this method as well as the back up option, in case man is not able to deliver sperm on the day of oocyte collection
Still, the dominant reason for cryopreservation of eggs today is the so-called social freezing. Because our eggs age together with us, quality decreases with age and the number of chromosomally abnormal oocytes increases. It is therefore an advantage to freeze oocytes at a younger age so we can use them successfully in future time.
Today, this method become another modern way of infertility treatment, as the survival rate of oocytes after thawing and their fertilization is approaching almost 100%.
Groups of women for whom oocyte freezing is appropriate.
1 / women who do not yet have a partner or women who wish to become pregnant only at a later age, for example after graduation or after building a professional career
2 / women who work in a harmful work environment and whose eggs are exposed to the harmful effects of the external environment - such as repeated long-distance flights, work with chemicals - (paints, varnishes), X-rays, work in a toxic environment, etc.
3 / women after ovarian surgery when part or all the ovary has been removed - (ovarian cysts, endometriosis)
4 / women with a familial predisposition to premature menopause
5 / women with cancer where chemotherapy or actinotherapy is expected
We recommend freezing eggs ideally at the age of 25-30 years, but it always applies – the sooner, the better!
