Klinefelter's syndrome
A genetic disorder in males caused by having an extra X chromosome. Males with this disorder may have larger than normal breasts, a lack of facial and body hair, a rounded body type, and small testicles. They may learn to speak much later than other children and may have difficulty learning to read and write. Klinefelter's syndrome increases the risk of developing testicular cancer.

Klinefelter syndrome
The most common single cause of hypogonadism (underfunction of the gonads) and infertility in men, Klinefelter syndrome is due to a chromosome abnormality with XXY (plus additional X or Y chromosomes). It affects about 1 in 500 males and results in small testes (hypogenitalism), underproduction of testosterone and infertility (hypogonadism), and a long-limbed, long-trunked, relatively tall, slim build. Klinefelter boys tend to have learning and/or behavioral problems. At adolescence there is little growth of facial hair and a third of boys develop gynecomastia (enlargement of the male breast). Named for the physician Harry Klinefelter who with E.C. Reifenstein, Jr. and Fuller Albright (the founder of modern endocrinology) described the condition in 1942 long before its chromosomal basis became known.

Klinefelter's syndrome
A genetic abnormality in a male characterized by two X chromosomes and one Y chromosome, infertility, smallness of the testes, and gynecomastia. It is associated with primary mediastinal extragonadal germ cell tumors found during puberty.
