Hormone therapy in women with premature ovarian insufficiency: a systematic review and meta-analysis.

The aim of this systematic review and meta-analysis was to evaluate the effectiveness of different hormone therapies, including hormonal contraceptives, in women with premature ovarian insufficiency (POI). Thirty reports of 28 studies were included, with a total of 4004 participants with POI from diverse aetiologies, of whom 3785 received hormone therapies and 219 received calcium supplementation, vitamin D, placebo or no treatment. Hormone therapy was superior to non-treatment, placebo, calcitriol or calcium in preserving bone mineral density (BMD) in women with POI.
