The World Health Organization has defined the period between the ages of 10-19 as adolescence, 15-24 years as youth and 10-24 years as youth period. Adolescence is divided into 3 periods: early adolescence (10-13 years), middle adolescence (14-16 years) and late adolescence (17-21 years). HIV virus and AIDS, which have become a problem among sexually transmitted diseases all over the world, have increased the importance of controlling sexually transmitted diseases. There is a strong correlation between the spread of STDs through traditional means and the transmission of HIV; and sexually transmitted diseases have been found to increase the risk of sexual transmission of HIV. According to WHO data, 340 million treatable STDs, millions of incurable STDs and 5 million HIV cases occur worldwide each year.

People in the 15-49 age group who are sexually active are the most likely to contract sexually transmitted diseases. The prevalence of STDs is higher in developing countries than in developed countries. These diseases are among the top 5 etiologic factors that cause loss of years of "healthy productive life" in developing countries. As in other countries, sexually transmitted diseases are of great importance in terms of complications and sequelae in Turkey

One out of 20 young people is infected with STDs every year. In our country, the age of sexual maturation has shifted earlier. In addition, the age of sexual experience of young people has also shifted earlier. Young people's understanding of freedom and their inability to access FP methods whenever they want negatively affect their sexual health behaviors. Impact on Society STDs cause a lot of economic and social damage to society. STDs may disrupt the normal functioning of family, community and health institutions and leave these institutions under a heavy economic burden. STDs reduce the productivity of men and women at the most productive ages of their lives. In addition, when outbreaks of these infections are not controlled, the costs to society will increase.
