The development of contraceptive methods allowed and induced the change of social and cultural patterns, improving peoples' quality of life and health. Today more than 550 million couples are using contraceptive methods. 1 The large-scale use of contraceptives triggered the most powerful revolution ever seen in reproductive health and gender equity. a) Background 1) Introduction 1.Diczfalusy E. Contraception and society. Eur J Contracept Reprod Health Care Dec;7(4): Diczfalusy E

In the last 20/30 years: Information about new contraceptive methods has severely increased. 2 STD infection rates among young people has been rising considerably, chiefly due to misinformation and unawareness. 2 This information boom leaded to incorrect concepts and myths. 2 2.Segal SJ.

2) Study Planning a) Type of study To achieve the aim of this project, an observational transversal study was designed. After choosing two colleges, a randomly groups sample was administrated to subjects. Advantages: conclusions taken with rapidity/promptitude Disadvantades: the information produced is limited

Participants were separated into subgroups by selected characteristics, such as attended Faculty, year of study and gender. We studied 131 students: approximately 65 students from each Faculty: Faculdade de Medicina da Universidade do Porto and Faculdade de Economia da Universidade do Porto. The students inquired were from the first grade. In this subgroup of 65 students we had a representative sample of each gender. I.Participants selection b) Development of the study

Medicine Faculty: From the 22 classes (in average each class has 11 students), we randomly selected 6, so that we obtained approximatly the 50 students we firstly proposed to study. The questionnaire was delivered during a practise class, so that we assure the majority of students were present. Economy Faculty: We randomly selected a practise class (practise classes have approximatly 70 students).

By now, we are only able to analyse the influence of gender and study area among 1st year students; We are still collecting the information from the 4th year students, so that we can also evaluate the effect of age and university environment. Approximately the same number of students in 4 th grade is being inquired.

II.Questionnaires analysis First of all, we codified the questions and introduced the variables in SPSS. Print screen of the variable view

According to the codification we introduced the data on the program. SPSS allowed us to analyse statistically the participants answers. Print screen of the data view
