Leepson sees sex education as instruction in various physiological, psychological and sociological aspects of sexual response and reproduction. Kearney (2008) also defined sex education as "involving a comprehensive course of action by the school, calculated to bring about the socially desirable attitudes, practices and personal conduct on the part of children and adults, that will best protect the individual as a human and the family as a social institution." Thus, sex education may also be described as "sexuality education", which means that it encompasses education about all aspects of sexuality, including information about family planning, reproduction (fertilization, conception and development of the embryo and fetus, through to childbirth), plus information about all aspects of one's sexuality including: body image, sexual orientation, sexual pleasure, values, decision making, communication, dating, relationships, sexually transmitted infections (STIs) and how to avoid them, and birth control methods. Various aspects of sex education are considered appropriate in school depending on the age of the students or what the children can comprehend at a particular point in time. Rubin and Kindendall expressed that sex education is not merely the topics of reproduction and teaching how babies are conceived and born. Instead, it has a far richer scope and goal of helping children incorporate sex more meaningfully into their present and future life and to provide them with some basic understanding of virtually every aspect of sex by the time they reach full maturity.
