Virginity testing has been practiced in some cultures for years to determine purity before marriage. Some countries have revived the practice to help prevent the spread of HIV/AIDS, though it is controversial due to human rights concerns. Virginity testing methods vary by culture and can include inspecting the hymen, which is a sensitive part of the female anatomy that can easily tear from activities other than sex. While supporters believe it discourages early sex and HIV, critics argue it is inaccurate and may put women at risk of attack.
