Three newly conducted studies strengthen the evidence that a minor procedure of circumcision protects men against deadly AIDS virus and the sexually transmitted virus that causes cervical cancer in women.

Dr. Bertran Auvert and his colleagues examined more than 1,200 men visiting a clinic in South Africa.

They found that, less than 15 percent of circumcised males and 22 percent of uncircumcised men were infected and the carrier of HPV, which is the main cause of cervical cancer and genital warts in females.

“These studies explain, why the women with circumcised sex partners are at a reduced risk of cervical cancer than the women with the uncircumcised,” researchers said.

The circumcised men have half of the chances to have HPV than uncircumcised men, after few adjustments for other differences between the two divided groups, According to the second report.

In third report, Lee and colleagues, in Baltimore, tested African-American men and they came to know that just 10 percent circumcised have the high risk of HIV infection, compared to 22 percent of uncircumcised.

“Circumcision was linked with significantly reduced HIV risk in patients with known HIV exposure, suggesting that results of other studies demonstrating reduced HIV risk for circumcision among heterosexual men likely can be generalized to the U.S. context,” they wrote.

But they found that the American Academy of Pediatrics is not recommending regular circumcision for newborns.

“As a result of this decision, health insurance program for poor and disables (Medicaid) does not cover circumcision costs, and this is mainly prejudicial for poor African American and Hispanic boys who, may face high HIV exposure risk in their adulthood,” Gray and colleagues wrote.
