Symptoms of Klinefelter syndrome

Klinefelter syndrome (KS), also known as XXY syndrome, is a congenital disease that causes babies to be born with an extra X chromosome, hence the name. Males born with KS have low testosterone levels.

As a consequence, when the child reaches puberty, the development of the secondary sex characteristics never occurs. Common signs of KS are reduced muscle tone, sparse facial hair, small testicles, presence of breasts, etc.
