 It has been found that larger foreskins place uncircumcised men at an increased risk for HIV infection most likely due to the larger surface area of inner foreskin and the high concentration of Langerhans cells.Preputioplasty is the most common foreskin reconstruction technique, most often done when a boy is born with a foreskin that is too small; a similar procedure is performed to relieve a tight foreskin without resorting to circumcision.Circumcision is the removal of the foreskin, either partially or completely.
