Girls between the ages of 11 and 14 enter puberty. The period and a mixed up hormone household are accompanied by sudden fertility. Children in rural schools in developing countries are usually not prepared for this phase of life, family education often fails because of a high sense of shame and there is no corresponding access to the media. Puberty hits most girls in Cambodia and Laos completely unprepared. The period prevents them from attending school, they think they are ill, they have no place to go, no one to turn to, no knowledge of hygiene, no technical possibilities in the form of bandages, etc.
Lack of information/education is not least the reason for childhood pregnancy.
