Signs and Symptoms of Klinefelter Syndrome

According to the U.S. National Library of Medicine, Klinefelter syndrome is a condition that adds an extra X-chromosome to a male's genetic make-up. Klinefelter syndrome is only found in males, and it occurs in approximately 1 in every 500 American males.

Motor Skills

The added X-chromosome may slow motor development in male children, causing delays in crawling and walking.

Infertility

According to Medicinenet.com, nearly 99 percent of the males afflicted with Klinefelter syndrome are infertile because they are unable to produce an adequate amount of sperm.

Appearance

Males with Klinefelter syndrome tend to be taller and grow less facial hair than males without the condition. Klinefelter syndrome can also increase the probability that these males will develop a weight problem as they age.

Breast Symptoms

Klinefelter syndrome can cause the male's breasts to become tender to the touch, and it can also increase the odds of breast cancer.

Intellectual Development

Males with Klinefelter syndrome tend to take longer to learn to read and write. They display normal levels of intelligence, but these levels develop later.
