Freezing of oocytes

This represents a method of freezing oocytes (eggs), which is implemented in women before cancer treatment or in women who do not plan to become pregnant at the moment and want to keep their eggs frozen for the future (the so-called social freezing). Freezing of eggs is preceded by hormonal stimulation of the ovaries taking approximately 12 days. The retrieval of mature eggs is performed under general anesthesia and the obtained eggs are immediately frozen and stored in liquid nitrogen. Cryopreservation is performed by vitrification – ultra-fast freezing of eggs in special straws.
