Anti-mullerian hormone as a predictive marker for the selection of women for oocyte in vitro maturation treatment

Abstract
Purpose: In oocyte in-vitro maturation (IVM) treatments, the chances to achieve a pregnancy are critically dependent on the retrieval of a suitable number of oocytes. In this study, we assessed the ability of circulating levels of anti-mullerian hormone (AMH) to identify normo-ovulatory women suitable for IVM treatment on the basis of the number of retrieved oocytes.
Results:The overall pregnancy rate per embryo transfer was 16.6% (25/151) and the implantation rate was 10.9% (30/278). Linear regression and receiver operating characteristic (ROC) analyses were applied to identify independent variables and quantify a cut-off AMH value able to identify patients suitable for IVM treatment. An AMH value of 1.28 ng/ml was identified as a threshold for the prediction of the retrieval of at least 5 oocytes, with a sensitivity of 93.4% and a specificity of 33.8%. Positive and negative predictive values were 67.6% and 75.0%, respectively.
Conclusions: AMH can be adopted to identify women candidate for an IVM treatment from whom a suitable number of oocytes may be retrieved. This is of crucial significance during a non-stimulated cycle, in order to prevent an insufficient oocyte collection and rescue the treatment by implementing a conventional controlled ovarian stimulation.
