Moreover, the study found that increase of school dropout rate, street children, poverty and diseases were the effects of student pregnancy. In addition to that, various measures should be taken to reduce or eradicate the student pregnancy such as education to parents and students, building of hostels, punishment for those who impregnate students and to the large extent, collaboration between parents and teachers should be also considered so as to monitor and control the behavior of students.
