Were you looking for information about Klinefelter Syndrome? Kleinfelder syndrome is a common misspelling of Klinefelter syndrome.
Men who have Klinefelter syndrome have an extra X chromosome in each cell. This genetic disorder affects male sexual development, often causing breast development, small testes, and sparse facial and body hair. Also, because their testicles do not develop normally, affected males may have low levels of the hormone testosterone when they reach puberty. As this is a chromosomal disorder, there is no cure for Klinefelter syndrome. However, treatment options may include testosterone treatment or surgery.
