The XXY genetic disorder is caused by an extra X chromosome in the XY pattern of a normal male. Such a chromosomal variation occurs in one out of every five hundred male births. It is a very bad disease and can affect people in a number of ways. This disorder is also called Klinefelters Disease, and even though reversing the genetic disorder is impossible, it is possible for other effects can be controlled.
Major treatment methods for XXY genetic disorder include the use of testosterone which is a hormone found in males. People suffering from this disorder also display large breasts and breast reduction surgery is often resorted to by sufferers. This disorder can affect the behavior of the male and have them behaving like members of the opposite sex. Such males also have reduced fertility and may have children only if assisted procedures are used.
Even though this extra chromosome is present in many persons, it is not necessary that all of them will exhibit the symptoms associated with this disorder and there are people who go through life without ever being aware of such abnormality in their genes.
