Circumcision may provide the following benefits;
make it easier to keep the penis clean
reduce the risk of urinary tract infections especially in childhood
prevents:
inflammation of the glans (balanitis) and the foreskin (posthitis)
the potential for scar tissue on the foreskin, which may also lead to phimosis (inability to retract the foreskin)
paraphimosis (swelling of the retracted foreskin resulting in inability to return the foreskin to its normal position)
provide a reduced risk of HIV, penile cancer, cancer of the cervix in female sex partners and some sexually transmitted infections (STIs), especially ulcerative disease such as chancroid and syphilis
