Intervention Description
Women were randomised to receive either metformin or placebo starting three weeks before initiation of a GnRH agonist during an IVF treatment cycle (seven weeks prior to oocyte collection and then stopped at oocyte collection). Seventy identical packs of metformin and 70 identical packs of placebo were supplied by DHP Ltd, Crickhowell, Powys (UK) a commercial clinical trial supplier. The randomisation service was provided by DHP Ltd.
