RESUMEN
@#Introduction: Penile length is defined as a length from base of penile until the tip of the glans. If the length of penile less than 2.5 standard deviations (SD) on average of its age it characterized as a micropenis. The aim of this study is to describe the penile length and micropenis condition in elementary school student. Method: This is a descriptive study to find out the penile length in elementary school boys. Penile length was measured from symphysis pubic to tip of the glans using a rigid ruler by stretching the penile or stretching penile length (SPL) and identified the micropenis condition. Results: There were 203 boys with age ranging from 6 until 13 years old. Mean penile length on all age groups are slightly above mean - 2.5 SD. Micropenis was found in 52 boys (22.6%), half of them are in 9 to 11 years old groups. Most subjects are Sundanese. Conclusions: The mean penile length in all age groups were shorter than the reference that we used. Majority of the subjects in our study were Sundanese, this finding suggest that Sundanese children has a shorter penile length than a subject used in our reference study. Micropenis case findings in this study turned out to be quite large and surprising.
