Klinefelter's Syndrome is when a boy is born with an extra copy of the X chromosome. This is a genetic condition that only affects males. Klinefelter's Syndrome affects the growth of a boy's testicles, more specifically, a boy with this genetic condition might have smaller testicles than normal. This can result in a lower production level of testosterone. Other signs of KS can include lower muscle mass, enlarged breast tissue, and less body hair. KS is usually not diagnosed until adulthood.
Early treatment of KS can help to minimize the symptoms. There is no treatment that can be completed to help repair the extra X chromosome that man with KS is born with.
Some treatments include testosterone replacement therapy, breast tissue removal, speech and physical therapy, educational support for those that have a harder time learning due to KS, fertility treatment, and psychological counseling.
Until now, only about one fourth of all people that have ever had KS have been actually diagnosed with this genetic disorder. With more studies being done over the years, and more men being diagnosed, doctors are more aware of what symptoms to look for and what the best treatment options are for their patients.
Thank you so much! :D
