ABSTRACT
There are essentially two types of ovarian transposition: median transposition behind the uterus and lateral transposition outside the true pelvis. The choice is determined by the field and mode of radiation. Median transposition is used for inverted Y-field of radiation in Hodgkin’s disease, which is rare and associated with high scatter radiation. Lateral transposition just outside the true pelvis is suitable for brachytherapy (midline tumors such as vaginal, uterine and bladder tumors), while more lateral transfer is necessary for external radiation.
