Guideline for cryopreservation of unfertilized eggs and ovarian tissues in Japan Society of Reproductive Medicine

The Japan Society of Reproductive Medicine (JSRM) issued the guideline for cryopreservation of unfertilized eggs and ovarian tissue in 2013. The Japan Society of Obstetrics and Gynecology also announced the society opinions concerning cryopreservation of unfertilized/fertilized eggs and ovarian tissue in 2016, independently. To integrate these statements and to reflect the development of current therapeutic modalities in Japan, ethics committee of JSRM revised the guideline for cryopreservation of unfertilized eggs and ovarian tissues. First, considering that medical interventions for the treatment of malignancies might cause iatrogenic ovarian dysfunction, medical indication for cryopreservation of unfertilized eggs and ovarian tissues was specified. Second, the guideline of cryopreservation of unfertilized eggs and ovarian tissues for women that do not apparently possess malignancies and hope to preserve probable future fecundity was also described. Furthermore, requirements to be obeyed by facilities of reproductive medicine were raised to avoid the easy execution of these treatments. We hope that this new guideline could help the specialists of reproductive medicine in their daily practice and also would be helpful for women that definitely desire to preserve future fecundity. Notes Notes To obtain the IC set forth in the above item 3), the doctor specializing in reproductive medicine shall explain the following points. Members of Ethics Committee in Japan Society of Reproductive Medicine have no conflict of interest.
