Answer

For male infants, neonatal circumcision substantially decreases the risk of UTI. Schoen et al found that during the first year of life, the rate of UTI was 2.15% in uncircumcised boys, versus 0.22% in circumcised boys. [6] Risk is particularly high during the first 3 months of life; Schaikh et al reported that in febrile boys younger than 3 months, UTI was present in 2.4% of circumcised boys and in 20.1% of uncircumcised boys.
