XXY syndrome, also known as Klinefelter syndrome, is a genetic condition where a male is born with an extra X chromosome. Normally, males have one X and one Y chromosome. However, in XXY syndrome, the presence of an extra X chromosome leads to a variety of physical and developmental features and challenges, including reduced testosterone levels, which can affect physical development and fertility.
