Depiction of flaccid penis before and after circumcision showing what gets removed for extremes of style in each case the tissue to be removed is shown in orange. A before and B after for the low and loose style Almost all the inner foreskin has been removed along with an equal amount of outer foreskin. No tension has been placed in the shaft skin with the result that the flaccid penis droops and the sulcus is not held fully open. Thus despite circumcision it remains possible for smegma to accumulate. C before and D after for the low and tight style The maximum possible amount of inner foreskin has been removed along with the whole of the outer foreskin plus a considerable portion of shaft skin. This has placed the residual shaft skin under tension with the result that the flaccid penis appears to be short and semi-erect. The sulcus is held fully open therefore it is not possible for smegma to accumulate. E before and F after for the high and loose style Much of the of inner foreskin has been retained folded back on itself to face outwards and assume the role of shaft skin. The outer foreskin has been removed along with some shaft skin but not enough to place the residue under tension. Thus the flaccid penis still droops as it did before circumcision. The sulcus is not held fully open therefore it is still possible for smegma to accumulate. G before and H after for the high and tight style Much of the inner foreskin has been retained folded back on itself to face outwards and assume the role of shaft skin. The outer foreskin has been removed as has a considerable amount of shaft skin. This has placed the residual shaft skin under tension with the result that the flaccid penis appears to be short and semi-erect. The sulcus is held fully open therefore it is not possible for smegma to accumulate. Diagrams from http www.circlist.com styles page1.html terminology Male Circumcision An Appraisal of Current
