The Cambodian government has told Phnom Penh's Victoria International Hospital to stop advertising virginity restoration surgery services.

The Cambodian government has ordered a hospital to stop advertising so-called virginity restoration procedures, saying it harms the "morality" of society.

A number of Cambodian clinics quietly offer hymenoplasty - a procedure commonly sought after in countries where a woman's virginity is prized - but Phnom Penh's Victoria International Hospital is unusual in publicly advertising their services.

Information Minister Khieu Kanharith has told the hospital to "halt the advertisement offering virgin surgery".

"Your hospital has been advertising services about the technology of virgin surgery and altering women's vaginas on radio, TV, and in newspapers with excessive commentary which affects the long-lasting morality and beautiful traditions of Cambodian society," Kanharith said.

He added that the adverts also harmed "the dignity of other patients" who come to the hospital for unrelated treatment - without directly condemning the surgery in itself.

Kanharith has also ordered all media outlets in the country to immediately pull the adverts.

The hospital did not respond to requests for comment.

Cambodian women are under intense pressure to retain their virginity until marriage, as in many societies in Asia.

Some seek procedures to restore their hymen, despite the fact that the presence of an intact hymen - which can easily be broken without engaging in sexual activity - is not regarded as an effective way to test virginity.

In recent years Cambodia has also become notorious as a regional hub for selling young women's virginity to wealthy men, according to activists.
