The appearance of someone with Klinefelter syndrome can vary significantly, but often includes a combination of physical characteristics related to hormonal imbalances. These features are typically more pronounced after puberty.
Here's a breakdown of common characteristics:
-
Body Composition:
- Taller stature, often exceeding the average height.
- Less muscular build compared to individuals without the condition.
- Broader hips and longer limbs (arms and legs) relative to the torso.
-
Sexual Development:
- Smaller penis and testicles (microorchidism).
- Delayed or incomplete puberty, possibly requiring hormone therapy. Some individuals may not undergo typical pubertal changes.
- Reduced facial and body hair.
-
Other Physical Traits:
- Gynecomastia: Enlarged breast tissue.
- Weaker bones (increased risk of osteoporosis).
- Lower energy levels or fatigue.
It's important to remember that not all individuals with Klinefelter syndrome will exhibit all of these characteristics. Some may have only a few, while others may have a more pronounced combination. Diagnosis is typically confirmed through chromosome analysis.
