ABSTRACT
Sex differentiation is a genetically determined and controlled process that may be
altered by various types of genetic mutations or by the effect of hormones or other
environmental disruptors acting upon the embryo. The result is the formation of external genitalia that does not match with the genetic sex and the internal
genitalia. Mixed gonadal dysgenesis is classified into the sexual differentiation
disorders of chromosomal cause. Here is a one-year old child, who was seen at
“Juan Manuel Marquez” pediatric hospital since he presented with atypical external
genitalia. The diagnosis was mixed gonadal dysgenesis, based on supplementary
tests like gynecological echography, hormone studies and karyotype. The initial
treatment was surgical in two surgical times, and the hormonal follow-up lasted till
puberty (14 years) when the hormone replacement therapy started according to
the indications for the patient's age.
