China's high abortion rate has triggered public concerns over sex education for young people, with experts calling for cooperation from health departments and parents to protect young women.

About 13 million abortions are carried out in the country annually, according to the technology research center under the National Health and Family Planning Commission.

Sixty-two percent of these abortions are performed on women aged between 20 and 29, most of whom are single. Nearly 20 percent have had more than one abortion.
