In our world today most especially in the developing country, teenage pregnancy is as a result of traditional roles and early marriage, because teenage pregnancy is seen as a blessing and a proof that the young woman is fertile. In most cases, poverty contributes to this, when one does not have someone to take care of her at her early age.
In the developed world, the causes of teenage pregnancy is different in the sense that it is mostly outside marriage and carries lots of social stigma. Thus, adolescent sexual behaviour is one of the causes of teenage pregnancy. In our world today, having sex before 20yrs is the in thing, it is even the normal all over the world and this brought about high levels of adolescent pregnancy which creates sexual relationship among teenagers without the provision of comprehensive information about sex.
The in-take of drugs, alcohol etc contributes a lot to teenage pregnancy meanwhile as a teenager you may not be ready for sexual intercourse at that moment but being intoxicated with drugs and alcohol makes you to be involved in unintended sexual activity just because sex at that time is less emotionally painful and embarrassing. To avoid this, eradicate anything alcohol or drugs.
Furthermore, sexual abuse is also one of the causes of teenage pregnancy. Rape as a sexual abuse has more effect in the life of our teenage girls causing unwanted sex and teenage pregnancy.
Conclusively, age discrepancies also causes teenage pregnancy in the sense that a teenage girl with a partner much older than herself is more likely to get pregnant more often than a girl that have a partner of a close age, as she prefers having the children than abortion since she is not educated enough to use contraceptives.
