How does being circumcised help prevent the AIDS infection?
According to the Center for Disease Control (CDC), the inside of the foreskin contains less keratin—a waxy coating that helps prevent infection—than other parts of the penis. Because of this, it tears more easily during intercourse, providing an entry into the bloodstream for infections like HIV. The foreskin also contains more of the cells HIV tends to target (Langerhans cells) and has been more easily infected by HIV than other parts of the penis in laboratory studies. Finally, there is evidence that the environment between the unretracted foreskin and the head of the penis allows viruses to survive longer, increasing the likelihood of transmission.
There is still debate among medical professionals as to the extent that circumcision should be used as a prevention method. After all, plenty of circumcised men still get HIV! Keep in mind that wearing a condom, talking to your partners, and getting tested will help protect you from HIV transmission whether you’re circumcised or not.
