description To describe a 46,XX male with a hidden mosaicism. Clinical, hormonal and genetic findings are presented. The patient was a normal phenotypic male with a bilateral testicular volume of 10 ml. Hypergonadotropic hypogonadism (elevated serum concentrations of FSH and LH, and normal serum concentration of testosterone) without gynecomastia was found. Final karyotype was a 46,XX/47,XX + mar mosaic, with 3% of studied cells containing an abnormal SRY positive Y chromosome. XX males karyotype must include a great number of metaphases in order to ascertain a definitive genetic diagnosis.
