Were you looking for information about Klinefelter Syndrome? Kleinfelter syndrome is a common misspelling of Klinefelter syndrome.
Klinefelter syndrome is a type of genetic disorder that affects male sexual development. This condition results when there is a presence of one (or more) extra X chromosome in a male's cells. Extra copies of genes on the X chromosome interfere with male sexual development, preventing the testicles from functioning normally and reducing the levels of testosterone in the body. Possible signs of Klinefelter syndrome include breast development, small testes, and sparse facial and body hair. Treatment options may include testosterone medications, surgery, and counseling.
