Objective multicentre performance of the automated assays for AMH and estimation of established critical concentrations.

The measurement of AMH has now become widespread practice within the field of fertility treatment and research, despite technical issues with some of the original assays. The two new automated assays, with their potentially improved technical performance, require detailed examination and comparison under different conditions. In addition, the determination of categories of responses to ovarian stimulation, require re-evaluation for these new tests.
