It was hypothesized in the past that the layers of [[keratin]] resulting from [[circumcision]] provided a barrier of protection against [[Circumcision and Sexually Transmitted Diseases (STD's)| sexually transmitted diseases]]. In 1986, the late circumcision-advocate [[Aaron J. Fink]] invented the idea, without any evidence, that circumcision could prevent the transmission of [[HIV]], arguing that the hard and toughened glans of the circumcised male resisted infection, while the soft and sensitive foreskin and glans [[mucosa]] of the intact male were ports of entry.<ref>{{REFjournal | It was hypothesized in the past that the layers of [[keratin]] resulting from [[circumcision]] provided a barrier of protection against [[Circumcision and Sexually Transmitted Diseases (STD's)| sexually transmitted diseases]].

Recent studies have shown this hypothesis to be false.
