Question

Quizplus · Accepted Answer

Klinefelter syndrome is a sex-linked chromosomal condition affecting males, characterized by an extra X chromosome (XXY). It can lead to symptoms such as reduced testosterone levels, which can cause underdeveloped male sex characteristics and infertility. Testosterone replacement therapy is a common treatment to help manage symptoms, but it does not address infertility.
