Figure 4: Developmental steps of megameatus intact prepuce. Closure of urethral fold proximal to distally. (a) Arrest of urethral fold closure along with prepucial closure ventrally to form hypospadias (splayed glans and hooded prepuce). (b) Canalization of glanular plate started and proceeds proximally.) (c) Complete closure of urethral fold and prepuce. Canalization of glanular plate completed up to corona. However, there is no closure of glanular folds – Results in megameatus intact prepuce. (d and e) Closure of glanular plate results in normal development of penis and urethra
