Definition & Meaning of "Klinefelter syndrome"

What is "Klinefelter syndrome"?

Klinefelter syndrome is a genetic condition that occurs in males and is characterized by the presence of an extra X chromosome instead of the usual XY pattern. It is typically associated with physical features such as being tall, having long legs, reduced muscle strength, and small testes, which are the male reproductive organs responsible for producing sperm and testosterone. Individuals with Klinefelter syndrome may also experience developmental delays, learning disabilities, and behavioral issues. Additionally, they may have reduced fertility and an increased risk of conditions such as osteoporosis and breast cancer. Treatment for Klinefelter syndrome may involve hormone therapy to address hormonal imbalances and support physical development.
