Sex Education: Global Perspectives, Effective Programs, and Socio-Cultural Challenges presents a comprehensive and cohesive overview of sexuality education, including frameworks, challenges, and contexts that should be considered by developers of sexuality education programs. This book is divided into three sections: 1) Global Perspectives on Sexual Issues; 2) Effective Programs; and 3) Research on Sociocultural Challenges. The first section addresses a human rights point of view as a central and sensitive challenge to sex education and refers to the fact that the Western and Eastern countries of the European Union, Latin American, and the world as a whole need access to quality sex education with an impact on love, care, and respect of adolescents and young people. The second part of the book provides an overview of the status of sexual education programs based on Denmark, Ireland, and Mexico. In countries with fully developed comprehensive SE programs, authors show how teenage birth rates tend to be lower compared with countries in which SE is virtually absent. The last part of the book addresses three studies that show the importance of some sociocultural challenges that educators in sexuality may face when working with a vulnerable population such as women and men who have sex with men.
