NIH Rare Diseases:42 47, xxy refers to the presence of an additional x chromosome in a person's body cells. some individuals with a 47, xxy chromosome finding do not appear different from other individuals, and they may have mild symptoms or no apparent symptoms. during the first few years of life, most 47, xxy males do not show any obvious differences from typical male infants and young boys. children may have slightly weaker muscles, delayed development of motor skills, and learning and/or language problems. in later adolescence and adulthood, 47, xxy males can have features of klinefelter syndrome, which can include primary hypogonadism (decreased testosterone production), small testes, enlarged breast tissue (gynecomastia), tall stature, and/or other features. although the vast majority of individuals with 47, xxy identify as males, some develop atypical gender identities. there have been reports of individuals with 47, xxy having a female physical appearance, but in most cases this was attributed to changes in specific genes related to sexual development. most 47, xxy males are infertile, but many produce sperm and may be able to conceive with assisted reproduction. treatment varies among individuals and may include testosterone therapy; however, this therapy may not be appropriate for all individuals. last updated: 9/20/2013

MalaCards based summary: Klinefelter's Syndrome, also known as klinefelter syndrome, is related to infertility and azoospermia. An important gene associated with Klinefelter's Syndrome is GNRHR (gonadotropin-releasing hormone receptor). The compounds gnrh and cyclic amp have been mentioned in the context of this disorder. Affiliated tissues include breast, testes and bone.

Genetics Home Reference:21 Klinefelter syndrome is a chromosomal condition that affects male physical and cognitive development. Its signs and symptoms vary among affected individuals.

MedlinePlus:33 Klinefelter's syndrome (ks) is a condition that occurs in men who have an extra x chromosome. the syndrome can affect different stages of physical, language, and social development. the most common symptom is infertility. boys may be taller than other boys their age, with more fat around the belly. after puberty, ks boys may have smaller testes and penis breast growth less facial and body hair reduced muscle tone narrower shoulders and wider hips weaker bones decreased sexual interest lower energy ks males may have learning or language problems. they may be quiet and shy and have trouble fitting in. a genetic test can diagnose ks. there is no cure, but treatments are available. it is important to start treatment as early as possible. with treatment, most boys grow up to have normal lives. treatments include testosterone replacement therapy and breast reduction surgery. if needed, physical, speech, language, and occupational therapy may also help. nih: national institute of child health and human development
