Analysis of Shape and Retractability of the Prepuce in 603 Japanese Boys
Abstract
Purpose:
We evaluated preputial development in Japanese boys.
Materials and Methods:
Preputial retractability and formation of a tight ring were evaluated in 603 Japanese boys 0 to 15 years old.
Results:
The incidence of a completely retractable prepuce gradually increased from 0 percent at age 6 months to 62.9 percent by 11 to 15 years, while that of a tight ring decreased with age from 84.3 to 8.6 percent. Nine boys had balanoposthitis but none had a symptomatic urinary tract infection.
Conclusions:
Incomplete separation of the prepuce is common and normal in neonates and infants, and preputial separation progresses until adolescence. Awareness of these findings will eliminate unnecessary circumcision in boys.
