The<unk>  is a standard for measuring the amount of<unk>  which covers the glans penis of  an individual adult male. It was developed by Paul Sherriff, a<unk>  restorer. The index ranges from<unk>  index (CI) 1 -10, with 1 for those with very little skin and these include  those who were very heavily circumcised. CI 10 on the other hand refers to those with very long<unk> s which completely covers the glans whether it is in the flaccid or erect state.
The<unk>  index is often used by<unk>  restorers as a benchmark for evaluating progress in  non surgical<unk>  restoration with CI 4 being considered the most important milestone for any would be restorer as it is the stage where the<unk>  begins to cover the rim of the glans.
