What is ovarian transposition and when is it a good fertility preservation option?

In certain circumstances, patients will have their cancer treated by focused beams of radiation which are directed to their pelvis, where the ovaries are. In these circumstances it’s possible ahead of time to move the ovaries to another position in the abdominal cavity, which is higher and off to the side, so that the ovaries are not affected nearly as much by the beams of radiation. This procedure is called ovarian transposition. Remarkably, it is not always necessary later on to replace the ovaries back into the original position that they were moved from because when the ovary is surgically moved, the fallopian tube by and large moves along with it. So patients who have had ovarian transposition operations are often able to become pregnant without a second operation.
