The objective aimed was to obtain information about the sexual behavior of adolescents and youths attending university as regards contraception, pregnancy and abortion and the knowledge of the Papanicolau test as a preventive, method for malignant diseases. An anonymous survey which was especially designed for this investigation was implemented with 438 students - 123 women and 315 men - divided into three groups according to age; between 17 - 20, 21 - 24 and more than 25 years-old. Taking into account the sexually active population. 70% of the men between 17-20 use contraceptive methods (condoms 98,6%) and so do 100% of the women of the same age (menstrual cycle control method 71,4%, contraceptive pills 14,2%, or her partner uses condom 21,4%). In the group of youths between 21-24 years old, 76,8% of the men and 82,7% of the women use contraceptive methods: 70% of the men use condoms and 30% contraceptive methods used by their patner, whereas 58,3% of the women use the menstrual cycle control method, 25% take pills and 8,3% use DIU. In the group of older youths 71,4% of the men use contraception methods (66,6% condoms) and 51,14% of the women (100% the menstrual cycle control method) and 25% add other methods to this one. Only 20,68% of the women stated having had pregnancies (all of the between 21 - 24). As there is the same porcentage of abortion in this age groups, it can be presumed that all the pregnancies ended in abortion. This contradicts the position stated regarding abortion due to the fact that 66% of the population questioned in the survey was against abortion and defended the right to live, whereas 23% was for abortion mainly in the case of rapes and/or maternal diseases. A small porcentage was for abortion in the case of pregnancies which may disturb their life projects. As regards the Papanicolau test, all the groups have a good knowledge about it, but only women over 25 years old practice it responsably.
