Ten young patients with cervical cancer were treated by extraperitoneal ovarian transposition. All patients received pelvic irradiation post operatively. Sex hormone were analysed after treatment. 10 cervical cancer patients who were irradiated only were analysed as control. Our data suggested that extraperitoneal ovarian transposition has definite significance for reserving ovarian function in young patients with cervical cancer and improve the quality of operation. This operation is chiefly suited for young patients with early cervical cancer who were operated extra-peritoneally, also for young patients who are irradiated alone or before operation.
