When Is Ovarian Transposition Considered?

The procedure may be offered before pelvic radiation to a person who wants to preserve ovarian function. The cancer type, treatment plan, age, and likelihood of ovarian involvement affect whether it is appropriate. A discussion with the oncology and fertility teams can address other preservation options.

How Are the Ovaries Moved?

The surgeon frees and repositions one or both ovaries higher in the abdomen or to the side, outside the planned radiation area. They are secured in the new position while their blood supply is preserved. The operation may be performed laparoscopically or during another planned abdominal surgery.

What Happens After Surgery?

Recovery depends on the surgical approach and whether another operation was performed at the same time. The radiation team uses the new ovarian position when planning treatment. Follow-up may assess menstrual patterns, hormone levels, or fertility goals after cancer treatment.

What Are the Risks and Limitations?

Surgical risks include bleeding, infection, pain, and injury to nearby structures. An ovarian cyst or twisting of a repositioned ovary can occur. Ovarian function and future pregnancy are not guaranteed, since radiation scatter, chemotherapy, or damage to the uterus may still affect fertility.

Frequently Asked Questions About Ovarian Transposition

Are the ovaries removed during transposition?

No. The surgeon moves the ovaries to another position while preserving their blood supply. Removal of an ovary is a different operation.

Does ovarian transposition guarantee fertility?

No. The ovaries can still be affected by cancer treatment, and pelvic radiation can damage the uterus. Fertility specialists can explain options based on the planned treatment.

When is the procedure performed?

It is performed before pelvic radiation begins. It may be scheduled as a separate operation or combined with another planned surgery.

Does it protect the ovaries from chemotherapy?

No. Moving the ovaries reduces their exposure to the pelvic radiation field. Chemotherapy can reach the ovaries through the bloodstream and may still affect their function.
