Clinical Trial Summary

Hypospadias is a frequent malformation. The definition of hypospadias is a ventral tissues hypoplasia, with an abnormal position of the urethral meatus, a chordee of the penis and an open foreskin. It can be associate with other genital malformation; in that case it can be classified in the wider field of the disorder of sex development (DSD). There is a lot of surgical technics for those malformations.
