In this prospective randomized study, women with idiopathic karyotypically normal premature ovarian failure (POF) were treated with gonadotrophin-releasing hormone (GnRH) agonist and gonadotrophins with and without the addition of corticosteroids in an attempt to restore ovarian function. The study comprised 58 women with idiopathic POF randomly allocated to either GnRH agonists (GnRHa) plus gonadotrophin therapy with the addition of corticosteroids (29 patients) or GnRHa plus gonadotrophin therapy with placebo (29 patients). Ovulation occurred in six cases (20.7%) in the dexamethasone group versus three cases (10.3%) in the placebo group. There were two singleton pregnancies in the dexamethasone group. There were no reported complications from the use of dexamethasone apart from a sense of sleepiness and fatigue. The combination of corticosteroids with pituitary suppression followed by ovarian stimulation with gonadotrophin appeared to be beneficial in restoring ovarian function in patients with idiopathic POF and normal karyotype. © 2007 Published by Reproductive Healthcare Ltd.
