Objective: Assessment of the clinical and hormonal characteristics of patients with androgen insensitivity syndrome (AIS). Materials and methods: 20 cases of AIS were studied in the Endocrinology Unit of the Instituto Especializado del Salud del Niño (Institute of Child Health - Lima, Perú). Quigley criteria was used to assess ambiguous genitalia. Results: According this criteria the findings were the following: 10/18 (55,55%) of cases were stage III, 4/18 (22,22%) were stage IV, 2/18 (11,11%) were stage V, 1/18 (5,55%) were stage VI and 1/18 (5,55%) were stage VII. The last two stages had female phenotype (complete AIS). In patients with incomplete AIS the ratio testosterone/ dihydrotestosterone was less than 17, showing a mild failure of 5α-reductasa. This finding was not present in the cases with complete AIS. Conclusions: Due to the different degrees of ambiguous genitalia, the patients with AIS need genetic, hormone, images studies and surgical exploration to have the necessary criteria to suggest the most adequate therapy for each case.
