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.
Klinefelter syndrome, also known as the XXY condition, is a term used to describe males who have an extra X chromosome in most of their cells. Instead of having the usual XY chromosome pattern that most males have, these men have an XXY pattern. Klinefelter syndrome is named after Dr. Henry Klinefelter, who first described a group of symptoms found in some men with the extra X chromosome.
