In some countries, gender differences with premarital sex can be linked to virginity. In India, a woman may undergo a "virginity test" on her wedding night where she can be banished by her husband or subject to an honor killing if it's found she is no longer a virgin. Men are not subjected to this same test and could get away with having premarital sex. In Iran, if a husband finds out his wife had premarital sex, it can be used as grounds for divorce. Therefore, hymen reconstruction surgery is not uncommon for women who wish to prove their virginity.
