男性：克萊裏菲爾特綜合征  (Klinefelter Syndrome)

治 療
XXY性染色體組合是通過驗血來作出診斷的(即通過所謂的“染色體組型分析”的檢驗)。如今，這種診斷在產前檢查的一定時候進行，像通過羊水診斷(amniocentesis)或絨毛膜取樣(chorionic villus sampling，CVS)。但是，對於大多數的病例，發現症狀還是較晚了，要麼遲至男孩到了上學的年齡或進入了青春期才被發現病症。而且，剩下的病例直到成年期才被確診，例如直到醫生因為檢查男子不育症的病因時才被發現。雖然這個病症不能被“治癒”，它的許多症狀仍舊可以通過治療得到好轉。例如，一旦一個男孩被確診，在他進入青春期時，給予規律的“男性”激素睾丸酮的治療，能夠協助他長出面部的毛髮和發育出較為強健的肌肉型體格。

援助社團
過去，患有克萊裏菲爾特綜合征的男性及其家人常常感到孤立無助，也發現難以獲得更多的有關病症知識。然而，近年來，已經成立了許多援助社團。這些團體會樂意提供額外的知識，它們也在其他有關網站建立超連結，以提供幫助。這樣的團體的例子有(請點擊下麵的圖示)：

Causes of Intersexuality - Chromosomes

Males: Klinefelter Syndrome

Treatment
The chromosomal combination of XXY is diagnosed by means of a blood test (i.e. a chromosomal analysis called “karyotyping”). Today, the diagnosis is sometimes made before birth as a result of prenatal tests like amniocentesis or chorionic villus sampling (CVS). However, in most cases the condition is discovered much later when the boy enters school or reaches puberty. Still other cases are diagnosed in adulthood, for example when a doctor looks for the cause of a man’s infertility. While the condition as such cannot be “cured”, many of its possible symptoms can be treated. For example, once a boy has been diagnosed and reaches puberty, regular injections of the “male” hormone testosterone can help in growing facial hair and in developing a stronger and more muscular body.

Support Groups
In the past, persons with Klinefelter syndrome and their families often felt isolated and found it difficult to learn more about the condition. However, in recent years, a number of support groups have organized. They will gladly supply additional information as well as links to other related sites. For example these groups (click on logos):
