Klinefelter's Syndrome is very rare, it only occurs in 1 in 50,000 or fewer newborn males.

Application of Research Article

The new information I learned from my research is that only males can get this disease. Also, the male can get an extra chromosome which i didn't know. Also that Kinfelter's Syndrome can only occur to males. Klinefelter's Syndrome is incurable. It's very rare for males to get this disease. Also, that Klinefelter's Syndrome isn't inherited.
