Klinefelter syndrome, also known as congenital varicocele syndrome, is a relatively common genetic disorder with sex chromosome aberrations. The disease is characterized by patients having a classical anorchidic figure, gynecomastia, small testes, absence of spermatozoa, and elevated gonadotropins in the urine. The patient’s sex chromosome is 47, XXY, i.e., one more X chromosome than normal male, so Cranfelt syndrome is also called 47, XXY syndrome. The above content is for reference only.
