XXY, also known as Klinefelter syndrome, is relatively rare, affecting 1 in every 500 to 1,000 newborn males. Despite its rarity, it's one of the most common chromosomal disorders in males. It results from an extra X chromosome and can cause symptoms like reduced muscle mass, facial hair, and body hair; taller than average height; and infertility or reduced fertility. Although these symptoms can be managed, awareness and early diagnosis are critical for improving quality of life.
