Teenage pregnancy can be defined as 'babies having babies', referring to the existence of a fertilized fetus in girls aged between 13 and 17. Globally established norms have an age threshold at 18 years, at which time young people enter adulthood. In this connection, though females aged 18 and 19 are still technically teenagers, they are yet considered adults by international convention, with a statutory level of responsibility for themselves, their actions and their legal attachments.
