1 -- Individuals having the XXY chromosomal makeup might have an alteration in the development of secondary sexual characteristics. This is a result of the genetic mutations in the sex-determining region Y gene. An enlarged penis and scrotum would not be present in the XXY male. There is no research to support the increased development of testicular cancer or the incidence of infertility.
