This group of patients are real, narrow gender heritability, which determines the three main criteria of individual sex: gonads, genital organs, external genitalia are contradictory to those with obvious cases of chromosomal aberrations and severe hypospadias And when the children were female nurture cases are removed, through this screening a total of 12 cases. We divide these 12 cases into Krebs’ s taxonomy according to their use so far: the case of true hermaphroditism, 3 cases of male pseudohermaphroditism and 5 cases of female pseudohermaphroditism. None of these 12 cases had a history of family history and were not adopted during pregnancy
