* Circumcision lowers your son’s chances of getting a urinary tract infection (UTI) in the first year of life.
* Although a rare condition, cancer of the penis is essentially eliminated in circumcised males.
* Research shows that males who are circumcised have a slightly lower risk of getting sexually transmitted diseases (STDs).
* Circumcision eliminates foreskin infection that occur at the peak ages of 3 to 5 years.
* Circumcision prevents phimosis, a narrow opening that makes it impossible to retract the foreskin at a later age.
* Genital hygiene, which is particularly important in unsanitary conditions, may be easier after circumcision.
