protect yourself In the United States , infant circumcision is declining . About 64 percent of American male infants were circumcised in 1995 , down from more than 90 percent in the 1970s . Rates tend to be higher in whites -LRB- 81percent -RRB- than in blacks -LRB- 65 percent -RRB- or Hispanics -LRB- 54 percent -RRB- . Some opponents say the removal of the foreskin is an unnecessary surgical procedure that may reduce sexual sensitivity in adulthood . In Jewish and Muslim cultures , young or infant boys are routinely circumcised for religious reasons . Circumcision rates have traditionally been higher in the U.S. than in Europe , but the American Academy of Pediatrics currently says that the medical benefits are insufficient to recommend circumcision for all baby boys . In the new study , a research team at the Rakai Health Sciences Program in Uganda -- in collaboration with researchers from the Johns Hopkins University Bloomberg School of Public Health in Baltimore , Maryland , and Makerere University in Uganda -- conducted two clinical trials involving 3,393 uncircumcised men ages 15 to 49 .

Circumcision rates have traditionally been higher in the U.S. than in Europe , but they 've been on the decline . The finding adds to the evidence that there are health benefits to circumcision . It was already known that circumcision can reduce the risk of penile cancer , a relatively rare disease . In a previous study , the same research team found that adult circumcision could reduce the risk of HIV infection . Efforts to increase the practice of male circumcision in areas with high rates of sexually transmitted infections , including Africa , could have a tremendous benefit , say the study 's authors . Genital herpes has been associated with an increased risk of HIV , and HPV can cause genital warts as well as a higher risk of anal , cervical -LRB- in women -RRB- , and penile cancers .
