Klinefelter's syndrome, is a condition caused by males

inheriting an extra X chromosome in addition to their already

existing sex chromosomes. Typically having an XXY instead of a

normal XY sex chromosomes.


Symptoms include:

  • Sterility (almost all the time)
  • Gynecomastia; which is increased growth of breasts
  • Hypogonadism; which is decreased testicular hormones

And generally, having more female sex characteristics and less male

sex ones.
