Klinefelter syndrome is a hereditary disease which affects only males. Testicles of patients are small and hard. Production of testosterone slows down, resulting in low level of testosterone in serum. Your breasts look like those of females. There is no difference between patients and normal children at birth and in childhood. Differences start to appear from puberty. Klinefelter syndrome patients produce little or no sperm. Assisted reproduction methods can help some patients father a child.
