OBJECTIVE: To report a case of an azoospermic subject with mild androgen insensitivity syndrome (MAIS) and review the relevant literature. DESIGN: Case report. SETTING: Academic research hospital. PATIENT(S): A 49-year-old man with undermasculinized features and a history of cryptorchidism and azoospermia. INTERVENTION(S): Hormonal evaluation and genetic testing of the androgen receptor gene (AR). MAIN OUTCOME MEASURE(S): Hormonal levels and sequence chromatogram of the proband and his mother. RESULT(S): We found total T in the normal range and high levels of gonadotropins. Karyotype was 46,XY. Genetic testing identified a novel mutation of exon 1 of AR, which resulted in an alanine to serine substitution in the transactivation domain at codon 240 (A240S). Fourteen other mutations of exon 1 of AR have been associated with MAIS to date. CONCLUSION(S): The novel mutation A240S of AR is involved in MAIS, a syndrome associated with azoospermia.
