Klinefelter syndrome (KS) also known as 47,XXY or XXY, is the set of symptoms that result from two or more X chromosomes in males.[2] The primary features are sterility and small testicles.[2][8] Often, symptoms may be subtle and many people do not realize they are affected.[1] Sometimes, symptoms are more prominent and may include weaker muscles, greater height, poor coordination, less body hair, breast growth, and less interest in sex.[1] Often it is only at puberty that these symptoms are noticed.[4]Intelligence is usually normal; however, reading difficulties and problems with speech are more common.[1] Symptoms are typically more severe if three or more X chromosomes are present Klinefelter syndrome usually occurs randomly.[3] An older mother may have a slightly increased risk of a child with KS.[3] The condition is not typically inherited from one's parents.[3] The underlying mechanisms involves at least one extra X chromosome in addition to a Y chromosome such that the total chromosome number is 47 or more rather than the usual 46.[9] KS is diagnosed by the genetic test known as a karyotype.[4]    Are U married?
