Klinefelter syndrome was first described in 1942 by Dr. Harry Klinefelter, an endocrinologist at Massachusetts General Hospital. He published a case study of nine adult men with a common set of symptoms involving hypogonadism. At the time, chromosomes had not yet been discovered.
The term Klinefelter (pronounced KLAHYN-fel-ter) syndrome, or KS, describes a set of features that can occur in a male who is born with an extra X chromosome (pronounced KROH-muh-sohm) in his cells. It is named after Dr. Henry Klinefelter, who identified the condition in the 1940s.
