More recently, Alfano et al. (2017) investigated the role of serum AMH in a more homogenous single-centre cohort of 47 white-European men with iNOA undergoing mTESE; their results showed that while circulating hormone levels associated with a condition of primary hypogonadism did not predict SR, AMH levels, and the AMH/tT ratio did achieve independent predictor status for SR outcomes at mTESE, with a predictive accuracy of 93% and 95%, respectively. Here, AMH is linked to Hypergonadotropic hypogonadism.
