Oocytes could be frozen and stored for various reasons:
⊕ The patient will or is currently undergoing a type of treatment, such as chemotherapy or radiotherapy, that disrupts egg production.
⊕ The patient wants to postpone maternity due to various reasons.
The patient that whose oocytes are set to be frozen initially undergoes a typical in-vitro fertilization treatment. The oocytes are then retrieved and frozen.
In this process, we employ a mix of special solutions and liquid nitrogen. The oocytes can be indefinitely preserved in this solution.
