Uncircumcised men were first shown to be more likely
to acquire heterosexual HIV infection over a decade ago,
in articles in the leading medical journals "Lancet" and
"New England Journal of Medicine". Since then over 40
separate studies have shown that uncircumcised men are
more likely to become infected with HIV on heterosexual
exposure. The ease with which the foreskin tears during
intercourse, leaving mini-abrasions through which the
virus enters, can lead to the infections. It has recently
been shown that certain specialized cells in the foreskin,
Langerhans cells, can trap the HIV virus and promote infection.
