In fact, the only significant sexual difference between adult males and teenage boys with Klinefelter syndrome and other males their age is that the males with Klinefelter syndrome may have less interest in sex. However, regular injections of the male sex hormone testosterone can bring sex drive up to normal levels.

In some cases, testosterone injections lead to a false sense of security. After receiving the hormone for a time, males with Klinefelter syndrome may conclude they've derived as much benefit from it as possible and discontinue the injections. But when they do, their interest in sex almost invariably diminishes until they resume the injections.
