〔Sumiyoshi&Ginza〕Oocyte Cryopreservation

At our clinic, we are performing cryopreservation of oocytes on unmarried women.
We have cultivated among those undergoing infertility treatment, a long performance in the preservation administration of the frozen oocytes that have passed a long-term, cultivated and freezing technology. 
If you are thinking about what you can prepare now for what to provide for the future pregnancies, please consult us.


【The process of Oocyte Freezing】

1. Ovulation Induction In order to oocyte pick up with efficiency, we are growing multiple oocytes by use of internal medicine and injections.  There is also the method not using ovulation induction at all, and just to wait for the natural growth of the oocytes.
2. Oocyte Pick-Up We collect the oocytes by inserting a needle into the ovaries. (It is similar to an easy operation that can be done as a “1 Day Procedure”.)
3. Cryopreservation From the Super fast vitrification preservation method, we will do the cryopreservation in the liquid nitrogen.
