Klinefelter Syndrome is where males are born with an extra X chromosome, which may come from either the father’s sperm or the mother’s egg.

People can live normal lives with Klinefelter Syndrome. However, the main issue is that there is a high probability of having fertility problems that can be targeted through fertility treatment.

Symptoms of Klinefelter Syndrome:

  • Babies may have weak muscles
  • Infants have delayed speech
  • Taller than average height for age
  • Delayed or incomplete puberty resulting in small testicles and less facial hair
