Goserelin / leuprolide (ovarian function suppression)

Monthly or 3-monthly injections that switch off the ovaries, letting premenopausal women use aromatase inhibitors and lowering recurrence in higher-risk cases.

GnRH agonists induce reversible medical menopause. SOFT/TEXT showed OFS + exemestane or tamoxifen reduces recurrence versus tamoxifen alone, with absolute gains largest in women who needed chemotherapy. Also used for fertility preservation during chemotherapy (POEMS).
