The invention relates to a method for the treatment of an oestrogen-dependent proliferative disorder of the uterus such as endometriosis and uterine fibroids in a patient, by administering an aromatase inhibitor to the patient intravaginally. This achieves high local levels of aromatase inhibitor Locally, and therefore avoids some of the adverse reactions that are observed when aromatase inhibitors are delivered orally. Further, intravaginal delivery allows inhibition of the local lesional production without significantly affecting the circulating levels which have been produced by the ovaries. This results in minimal side-effects and will allow for longer term treatment than current therapies.
