Klinefelter syndrome (KS), also known as 47,XXY, is an aneuploid genetic condition where the recipient has an additional copy of the X chromosome. As the presence of a Y chromosome denotes male sex, people with Klinefelter syndrome are still genetically male, although they occasionally suffer health complications.
The Klinefelter syndrome has different manifestations and these will vary from one patient to another. Among the primary features are infertility and small, poorly functioning testicles. Often, symptoms may be subtle and many people do not realize they are affected. Whereas some other times symptoms are more prominent and may include weaker muscles, greater height, poor motor coordination, less body hair, gynecomastia (breast growth), and low libido. In the majority of the cases, these symptoms are noticed only at puberty.
