If radiation is planned in the lower abdomen and the ovaries are within the radiation area, this can lead to a loss of fertility. To prevent this, the ovaries can be moved out of the radiation area using a laparoscopy. During this operation, it is also possible to remove ovarian tissue, which can be frozen and transplanted again later. Of course, such a relocation of the ovaries is also conceivable as part of a planned abdominal operation for the underlying disease. The prerequisite is an abdomen free of adhesions (no history of major abdominal surgery and no prior infections in the abdominal cavity).
