As you probably already know, up until about 8 weeks gestation, the male and female are the same. After that point, the penis expands greatly and develops. Part of that development is that the underside of the penis joins the two sides to form an urethra. The ventral raphe, the little ridge along the underside of the penis is the result of this joining of the two sides. It is similar to a scar. Hypospadias is simply where the joining process is not complete and the urethral opening is somewhat further down than normal. It may be just slightly off center and appear as an elongated meatus, a cleft glans or it may be further down at the base of the glans, anywhere along the shaft or even below the scrotum. Regardless of where the opening is, from that point to the tip of the penis will be mucosal skin that would have been the urethral tube. To fashion a urethra from the current opening to the tip of the penis is simply a matter of bringing the two sides of the mucosal skin together. The skin in the butterflied area is the urethra that just didn't lap over to form the tube. All of the material is there, the process is just not complete. Any surgeon that has used foreskin or mouth lining as donor material can do the Scottish procedure with no problem.
