The physical appearance of a person with Klinefelter syndrome can vary, but some common characteristics are often observed. Klinefelter syndrome is a genetic condition that affects males and is typically characterized by the presence of an extra X chromosome (XXY instead of XY).
Common Physical Characteristics
While not every individual with Klinefelter syndrome will exhibit all of these traits, here are some common physical features:
- Atypical Body Proportions: Individuals may exhibit unusual body proportions, such as being taller than average, having longer legs, and a shorter torso.
- Smaller Penis: Some individuals may have a smaller penis.
- Undescended Testicles: One or both testicles may not descend properly.
Summary of Physical Characteristics in Klinefelter Syndrome

It is important to remember that Klinefelter syndrome presents differently in each individual, and some people may have only mild symptoms or not be diagnosed until adulthood.
