A case of complete androgen insensitivity syndrome presenting with incarcerated inguinal hernia: an immunohistochemical study

Negative AR immunostaining could either reflect Sertoli-cell immaturity or a mutation resulting in no protein production. The AMH immunodetection, consistent with its high serum levels, could potentially reflect Sertoli-cell immaturity. The SOX-9 nuclear detection in the Sertoli cells was consistent with its role, inducing male sex differentiation, including AMH expression. The nuclear localization of PGDS in the spermatogonia needs further investigation.
