Background: The predictive value of anti-m ü llerian hormone (AMH) in Chinese women undergoing in vitro fertilization (IVF) treatment is data deficient.To determine the attributes of AMH in controlled ovarian stimulation (COS), oocyte yield, cycle cancellation, and pregnancy outcomes were retrospectivelyanalyzed.Materials and Methods: All patients initiating their first IVT cycle with GnRH agonist treatment in our center from October 2013 through December 2014 were included, except patients diagnosed with polycystic ovarian syndrome.Serum samples collected prior to IVT treatment were used to determine serum AMH levels.Results.: A total of 4,017 continuous cycles accordance with the including criteria were analyzed in the present study.Anti-mullerian hormone was positively correlated with number of oocytes retrieved.Overall, AMH was significantly correlated with risk of cycle cancellation and poor ovarian response (POR, three or fewer oocytes retrieved), with an area under the curve (AUC) of 0.83 and 0.89 respectively.An AMH cutoff of 0.8ng/mL had a sensitivity of 65.1% and a specificity of 84.6%for the prediction of cycle cancellation, and cutoff of 1.0ng/ml with a sensitivity of 64.5% and a specificity of 90.5% for the prediction of POR.Patients with AMH <0.8ng/ml had a 32.8-fold increased risk of cancellation as compared with patients with an AMH>2.0ng/mL (P<0.05, 95% CI, 11.3-94.9).However, AMH was less predictive of pregnancy and live birth, with AUCs of 0.55 and 0.53, respectively.Clinical pregnancy rate per retrieval according to AMH level (≤0.80, 0.81-1.00, 1.01-2.00, and >2.01ng/ml), stratified by patient age (≤30, 31-34, 35-37, 38-40 and >40 years), showed no significantly different (P>0.05).Even with AMH<0.8ng/ml, 53.8% of all the patients achieved pregnancy and 40.8% of patients achieved live birth after transfer (see Table 1).Conclusions: Anti-mullerian hormone is a fairly robust metric for the prediction of cancellation and how many oocytes may be retrieved after stimulation but is a relatively poor test for prediction of pregnancy and live birth.Patients with low levels of AMH still can achieve reasonable treatment outcomes and should not be precluded from attempting IVF solely on the basis of an AMH value.
