In boys, testicular enlargement is the first physical manifestation of puberty (and is termed gonadarche ).  Testes in prepubertal boys change little in size from about 1 year of age to the onset of puberty, averaging about 2–3 cm in length and about –2 cm in width. The size of the testicles is among the parameters of the Tanner scale for male genitals , from stage I which represents a volume of less than ml, to stage V which represents a testicular volume of greater than 20 ml. Testicular size reaches maximal adult size about 6 years after the onset of puberty. After the boy's testicles have enlarged and developed for about one year, the length and then the breadth of the shaft of the penis will increase and the glans penis and corpora cavernosa will also start to enlarge to adult proportions.  While 18–20 cm 3 is an average adult size, there is wide variation in testicular size in the normal population.
