Abstract
Teen pregnancy is considered to be a phenomenon that generates a high social and economic impact. Its study and intervention has focused on promoting the use of contraceptive methods and the disclosure of scientific information about sexuality; however, the high numbers persist. The present article aims to argue how a social system such as patriarchy can influence the construction of gender representations and the experience of teenage sexuality, which could lead to an unplanned pregnancy. The conclusion is that, although patriarchy affects and is expressed in the experience of sexuality, gender representations and romantic relationships of young people, there are other individual, social, economic and political variables that are articulated in the complex reality of teen pregnancy.
