Introduction: Klinefelter syndrome
A rare chromosomal genetic syndrome where the person has XXY chromosomes instead of XY or XX.
The person is usually male because of the Y chromosome,
but has lower levels of testosterone
and may have some female-like features
(because there are two X chromosomes).
Sterility is a possible complication.
The rarer subtype XXXY syndrome may lead to retardation.
