title: Anti-mullerian hormone as a predictive marker for the selection of women for oocyte in vitro maturation treatment.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Serum AMH was quantified in normo-ovulatory women younger than 39 years undergoing IVM treatment. After immature oocyte retrieval and IVM, maximum 3 mature oocytes were used for treatment and all resulting embryos were transferred, as established by law. From 177 cycles, 991 oocytes were recovered. Following IVM, 484 mature oocytes were obtained (50.1%).
  
  
  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.
