title: Spermaturia in two normal boys without other signs of puberty.
abstract: We report spermaturia in two normal boys with testicular volumes of 3 ml and no other signs of puberty. This supports the hypothesis that spermatogenesis can begin before any other signs of puberty and indicates that the definition of start of puberty as testicular volumes of 4 ml or more may be too rigorous.
