Sex education is almost mandated in the United States. The data reviewing sexual activity in the adolescent population indicates that large numbers of women under the age of 19 who have unintended pregnancies are at risk for an increased frequency of sexually transmitted diseases which will affect their future. It is essential that good educational programs and preventive service programs be developed and mandated for the adolescent population. Experience in Western Europe demonstrates that the adolescent who has a proper education concerning sexual activity, sexually transmitted disease, and contraception is at lower risk for the many problems that we see in the United States. There must be cross-cultural data that can be translated for use in the entire world. As the population of this world ages, we must protect those who are entering adulthood from being exposed to the STDs and undertaking the responsibility of parenting without having reached full maturity. The cost in dollars of the sequelae of adolescent pregnancies are great. These costs are not only financial, but also emotional and social, and they have a negative impact on the country in which the adolescent lives. We have a heavy responsibility as physicians and health care professionals to see that the adolescents of the world are given the knowledge and models to use to reduce the risk for pregnancy and the acquisition of a sexually transmitted disease.
