Klinefelter syndrome is a genetic condition that affects males, typically caused by an extra X chromosome. This can lead to a range of physical and cognitive symptoms, including underdeveloped genitals, infertiltiy, less body hair, taller than average height, learning disabilities, and in some cases, breast growth. The syndrome is usually diagnosed through genetic testing.
