How can i tell if i have delayed puberty or klinefelter syndrome?

Karyotype: A simple chromosomal test called a karyotype can rule out klienfelter syndrom.

Genetics: Klinefelter's syndrome is a genetic disorder unique to males. Those with it have at least 1 extra x chromosome. Boys are usually tall and may have learning problems, sometimes behavior problems. Puberty often starts normally but testicular failure often necessitates a need for testosterone supplementation. If you're concerned about puberty please discuss with your doctor.
