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.
