When circumcision is performed the entire glans penis, which is the flesh at the top of the sinew, must be completely clean, Sometimes, in children or adults, we see the foreskin covering  the glans penis or the ridge surrounding the glans penis.  

The Causes

• Incomplete removal of the foreskin, caused by a difficulty in catching hold of it. (A lack of skill or the mohel’s concern for pulling the skin)
• Incorrect cutting method
• Inflammation of the skin in the region of the cut, which is liable to cause adhesions and synechia of the glans penis
• In an overweight person, sometimes part of the glans penis is covered due to his size.

Whenever the glans penis is not completely visible, the mohel must check in order to determine whether the circumcision has been performed properly or needs to be repaired.
