What is Klinefelter’s Syndrome and What are the Symptoms?

Klinefelter’s Syndrome occurs in boys who have an extra X chromosome.

Klinefelter’s Syndrome Symptoms

Because they often appear no different from anyone else, many XXY males probably never learn of their extra chromosome.

However, if they are to be diagnosed, chances are greatest at one of the following times in life: before or shortly after birth, early childhood, adolescence, and in adulthood (as a result of testing for infertility).

Boys with Klinefelter’s Syndrome may have a language disability, but some do not have any trouble learning.

Teenagers with Klinefelter’s Syndrome may have less facial and body hair. Adults with this condition may be infertile.

How is Klinefelter’s Syndrome Diagnosed?

This condition can be diagnosed before birth through amniocentesis or chorionic villus sampling (CVS).

If the mother does not have an amniocentesis or CVS test, a small blood sample can be drawn from the child. White blood cells are then separated from the sample, mixed with tissue culture medium, incubated, and checked for chromosomal abnormalities, such as an extra X chromosome.

Klinefelter’s Syndrome Treatment

Treatment has the best results when its started as early as possible. With treatment, most boys can grow up to have normal sex lives.

Treatment can include:

  • Educational services
  • Physical, speech and occupational therapy
  • Testosterone replacement
