About Oocyte Cryopreservation

At this hospital, we are happy to provide cryopreservation services.
We have a long track record in freezing technology as well as long-term storage and management of frozen oocytes, both for oocyte cryopreservation and in other kinds of fertility treatment.
If you are thinking of preparing for your future pregnancy, please contact us.

Process of Oocyte Cryopreservation at Oak Clinic

1. Inducing Ovulation In order to collect oocytes efficiently, we use oral medicine and injections to get multiple oocytes. There is also a way to wait for the oocytes to grow naturally without inducing ovulation at all.
2. Oocyte Pick-Up In an outpatient surgery, a needle is inserted into the ovary to collect oocytes.
3. Cryopreservation The oocytes are cryopreserved in liquid nitrogen by the rapid vitrification method.
