Changes

Natural foreskins are found in all lengths from very short to very long. Most fall near the center of the range. Longer foreskins appear to perform their [[Immunological and protective function of the foreskin| protective and immunological function]] more satisfactorily. A Shorter foreskins or inadequate foreskin may be lengthened by [[tissue expansion]] to improve function and aesthetics.

The tapered tip of a longer foreskin that extends beyond the [[glans penis]] is known as the ''[[acroposthion]]''. A very few of the longest foreskins will not remain retracted when released, but will spontaneously [[Gliding action| glide]] forward to recover the glans penis. Longer foreskins improve protection and [[gliding action]] and do not usually create an issue. There is no recognized definition of an excessively long or so-called "redundant" foreskin.<ref name="tip2022">{{REFweb
