Vitrification is a technique used to freeze and preserve oocytes (eggs) for future use in fertility treatments. During vitrification, the oocytes are rapidly cooled to a very low temperature, which essentially stops all biological activity and prevents damage to the cells.
Vitrification is a relatively new technique for oocyte freezing, but it has quickly
become the preferred method due to its higher success rates compared to traditional slow freezing methods. Vitrification results in a higher survival rate of the oocytes after thawing, and a higher likelihood of successful fertilization and implantation when the oocytes are used in fertility treatments.
Vitrification may be recommended in a number of different situations, such as:
Women who wish to delay childbearing for personal or medical reasons
Women undergoing cancer treatments that may impact their fertility
Couples going through IVF who have extra oocytes that are not used in the
Women with conditions that may impact their ovarian reserve, such as
endometriosis and low ovarian reserve .
