Klinefelter's syndrome is a sex-linked chromosomal abnormality in which a male has an extra X chromosome (XXY instead of XY). This syndrome causes infertility, but testosterone replacement therapy can help develop male sex characteristics and improve mood. The other options, Turner syndrome, "Supermale" syndrome, and Down syndrome, are not treated with testosterone replacement therapy for the same reasons as Klinefelter's syndrome.
