A Tokyo fertility clinic said Wednesday it will open the nation's first ovary bank next month to help cancer patients conceive by removing and freezing their ovarian tissues before treatment.

Ladies Clinic Kyono said it has enlisted a range of medical facilities that treat cancer patients to set up an ovarian tissue preservation network.

Radiation treatment and chemotherapy often results in infertility, and removal and replacement of a young woman's ovaries is often the only hope for her to conceive.
