Corrective rape, where a male pupil rapes a female lesbian pupil to "make her heterosexual", was a growing phenomenon in schools, the SA Human Rights Commission (SAHRC) said in a report released on Wednesday.

A gay and lesbian rights group told the commission during public hearings that homosexual pupils experienced "high levels of prejudice" at school resulting in "exclusion, marginalisation and victimisation".

"There is a growing phenomenon of corrective rape. This refers to an instance where a male learner rapes a lesbian female learner in the belief that after such a sexual attack the learner will no longer be lesbian," the report said.
