46 XX male sexual disorder is a very rare disease. SRY (sexdetermining region Y) located in the Y chromosome is a main sex-specific gen location. It is thought that the translocation of Y chromosome part containing this gene region to the X chromosome is responsible for the disorder. A 35 year-old male patient was admitted to the outpatient clinic with complaints of infertility and decreased sexual desire. Physical examination revealed wrinkles on the face, lack of hair, short stature as well as small testicles. Hypergonadotropic hypogonadism and azoospermia were detected in the patient. The patient's karyotype analysis was reported as 46 XX. SRY gene analysis was positive. These patients do not have spermatogenesis, thus sperm can not be obtained with testis biopsy. The main treatment of the disease is testosterone replacement therapy. In the differential diagnosis of patients with primary hypogonadism presenting with infertility, this rare disease should be considered.
