the consequences of this official silence are plain to see. In 2010, Peking University, in cooperation with the United Nations Population Fund, conducted China's only national survey youth access to and use reproductive health services and education. Of 10,966 women between the ages 15 and 25, only 4% displayed adequate knowledge of sexual and reproductive health, with those aged 15-19 the least knowledgeable. Sure enough, over half of those surveyed hadn't used contraception their first sexual encounter. (Rates were even higher among migrant workers.)
