Symptoms
The symptoms of Klinefelter syndrome can vary widely among affected individuals, but there are some common physical and developmental characteristics associated with the condition. These may include small testes, reduced fertility, gynecomastia (enlarged breast tissue), tall stature, and decreased muscle mass.
Additionally, individuals with Klinefelter syndrome may experience learning and behavioral differences, such as language and speech delays, social and emotional challenges, and difficulties with executive function. It is important to note that not all individuals with Klinefelter syndrome will exhibit the same symptoms, and the severity of the condition can vary widely from person to person.
