Cryopreservation ofhuman oocytes to delay fertility also be an option for women who are going to be subjected to a cancer/autoimmune treatment. It allows for creating a bank of oocytes for donation in assisted reproduction centers. The legislation allows the use of cryopreserved oocytes throughout the reproductive life of women with what conservation could last up to 48-50 years. Oocyte vitrification is a ultrafast freezing method in which cryoprotectants are used to prevent the formation of ice crystals within the cell. Treatment for oocyte vitrification process is similar to IVF treatment, ending at the time of obtaining the ova. The eggs obtained in the laboratory are classified according to maturity and quality. The apartments will be cryopreserved by vitrification technique tanks and maintained in liquid nitrogen until used for reproductive purposes.
对人类卵母细胞进行冷冻保存以延迟生育，对于即将接受癌症/自身免疫治疗的女性来说也是一种选择。这使得在辅助生殖中心能够建立一个卵母细胞库用于捐赠。法律允许在女性的整个生殖寿命期间使用冷冻保存的卵母细胞，其保存时间最长可达48至50年。卵母细胞玻璃化是一种超快速冷冻方法，其中使用冷冻保护剂来防止细胞内形成冰晶。卵母细胞玻璃化过程的治疗与体外受精治疗相似，在获取卵子时结束。在实验室获得的卵子根据成熟度和质量进行分类。这些卵子将通过玻璃化技术罐进行冷冻保存，并保存在液氮中，直到用于生殖目的。
