Ovarian transposition is a surgical procedure in which the ovaries are displaced from the pelvis before pelvic radiation therapy in order to protect them from radiation injury.
It is performed in premenopausal women with a variety of pelvic malignancies (e.g cervical cancer, rectal cancer, and lymphoma).
The procedure increases the incidence of functional ovarian cysts and peritoneal inclusion cysts.
Locations for transposed ovaries include the lateral paracolic gutter, anterior to the psoas muscle above the pelvic brim, or within the pelvis in a far lateral position.
