"Sexual Health" is a free platform and applications designed for informational and educational purposes, with the aim of improving the understanding of the importance of responsible sexual behavior, healthy lifestyle and protection from sexually transmitted infections in order to maintain and improve health. It was conducted by the Croatian Institute for Public Health (CIPH) and the Croatian Association for the Fight against HIV and viral hepatitis (HUHIV). The application in a clear and interesting manner provides useful information about sexual and reproductive health, including the prevention, testing and treatment of sexually transmitted diseases, in accordance with current scientific and technical knowledge. Whether it comes to checking the risk, knowledge quiz, information or recommendations, we believe that everyone will find something for themselves.
