Foreskin restoration is the attempt to reverse the effects of circumcision.
It can produce a remarkably similar appearance to an original foreskin, and greatly improved sensation to the glans and to the partner, but It can never restore all that was lost, so It does not give any justification to infant circumcision. Surgical restoration has been known to give satisfactory results but it has also produced some disasters. It is expensive. The cosmetic surgeons who do it are mainly concerned with appearance. They tend not to know of the foreskin's function.
