Hi doctors i gain lot of information of klienfelter syndrome from net and see that some person with this syndrome have normal large testis possible

Klinefelter syndrome: is an extraordinarily complex set of signs and symptoms that result from two or more X chromosomes in males (instead of the usual one). Weaker muscles, greater height, less body hair, breast growth and low libido are common. There are low testosterone levels, but the testicles, though often smaller, may be normal in size. A comprehensive eval/chromosome analysis by specialist(s) is needed.
