The adolescent and young adult with Klinefelter syndrome:ensuring successful transitions to adulthood.

: As many adolescent and young adult males with Klinefelter syndrome move into young adulthood, they will require long-term medical and mental health care for their complex and specific health care needs. Adult general medical providers and endocrinologists may feel ill-prepared to meet the medical needs of this population. In turn, many pediatric primary care and subspecialty providers may find themselves struggling to determine how best to transition the older adolescent to adult-oriented services. Working with families and their teens to consider and address current and future medical, mental health, educational and vocational needs will enhance that young adult's independence and functioning. This chapter addresses general transition issues and those that are specific to adolescents with Klinefelter syndrome. The prognosis for these young patients is good, and can be further enhanced by supportive families and a medical team that is informed about how best to facilitate the transition to adult-oriented services.
