These glands, located on the mucosal skin of the foreskin, provide additional lubrication to the foreskin and glans when covered.  Not all intact men have sebaceous glands, but most are removed during circumcision.

The part of the penile sheath that covers the shaft from the pubic area up to the intact foreskin or circumcision scar. During non-surgical restoration, stretching this sheath along with any remaining inner foreskin stimulates mitoses, which creates new skin cells and ultimately a faux foreskin.

Also called adhesions, skin bridges are a common complication of circumcision where the remnants of the inner foreskin span the sulcus and fuse to the mucous membrane of the glans, usually at the corona. Depending on the size and location of a skin bridge, it may cause difficulty while restoring.

The groove or furrow encircling the penis between the flare of the corona of the glans and the smooth shaft of the penis. Also referred to as the "coronal sulcus."
