There is scarcely available data about the evaluation and evolution of patients with morphologically normal penis, but with reduced length according to the age. In this study, 8 boys were evaluated, with pre-pubertal development, presenting penis length one or two standard-deviation bellow average and with no evidence of endocrine pathology. In 6 cases the patients were observed for 1 year and 2 months to 8 years and 7 months. Two of them were submitted to testosterone treatment. In the last evaluation, all patients presented pubertal development, three of them with normal penis length for the age, and three of them presenting penis length one standard deviation bellow the average. The benign clinical evolution observed favors the adoption of expectant behavior in some of these cases, while testosterone treatment should be applied only in special ones.
