AMHR2 and varicocele: Still on the topic of different patterns of expression, Kistamás et al. have not found any statistically relevant correlation between AMHR-2 expression and age on the appendix testis [32] in a large series of patients undergoing surgical explorations for different conditions, such as hydrocele and varicocele; however, as the appendix testis is histologically different from testicular tissue [33], drawing an association with the present study is not feasible.
