Taking into consideration (1) the male characteristics of sexual development of the patient—absence of uterus, presence of phallus and prostate—(2) the female karyotype, (3) normal level of 17-OHP excluding congenital adrenal hyperplasia, (4) normal-for-boys level of AMH excluding gonadal dysgenesis and (5) the result of the hCG stimulation indicating the presence of testicular tissue, we concluded that the patient suffered from 46,XX TDSD. Here, AMH is linked to gonadal dysgenesis.
