Klinefelter syndrome, 47, XXY, or XXY syndrome is when people have an extra number of X chromosomes.[1] People who have Klinefelter's Syndrome are often called "XXY Males", or "47, XXY Males".[2] Other males can have Klinefelter's Syndrome as well (for example, mice).[3] Males who have this condition are almost always infertile. This means that they cannot father babies.[4]
