Pornography has long been a subject of interest to researchers, policy makers, and the general public. This chapter provides an overview of recent findings in pornography research with an emphasis on male sexuality. First, we present a brief summary focused on the definition of pornography. Then we outline the results of studies on pornography use along with details about how often men and women consume pornography, what type of pornography they prefer, and other aspects of pornography use. Finally, we address the results of some of the most significant research on the effects of pornography use on male sexuality, such as risky sexual behavior, sexual self-esteem and well-being, sexual dysfunction, sexuality in couples, and pornography addiction. The findings of current research on pornography are limited by methodological and theoretical shortcomings which compromise their generalizability. We provide a short overview of some limitations in the measurement of pornography use. All in all, many findings on pornography, its use, impact, and long-term effects are preliminary and should be interpreted with caution.
