ASCO endorses the following recommendations on ovarian ablation from Cancer Care Ontario:

• Ovarian ablation should not routinely be used with chemotherapy, tamoxifen, or a combination of these treatments.
• Ovarian ablation should not be used as an alternative to other treatments, unless a patient is not healthy enough for other treatments or if the patient chooses not to have other treatments.
• If ovarian ablation is chosen, monthly injections with an LHRH analogue is the best method. (ASCO's endorsement of this recommendation notes that treatment every three months may also be effective.)
