This paper touches on the importance of providing public awareness and education to our educators, parents, and students so that we reduce the number of girls that have onset puberty. It also provides information on how we can teach parents to be supportive during adolescents, which can be a difficult and confusing time for students, which is more important than ever. With the improvement of sexual education programs taught in our school systems, parents and teachers can adequately prepare students for the negative effects of sexual activity before it is too late. The numbers of adolescents engaging in sexual activity, STIs and teen pregnancies can be reduced. Adolescent Sexual Development。 Sexual maturation and growth spurts both accompany puberty and can be a difficult and confusing time for adolescents, especially with children hitting puberty at an earlier age than ever. It is essential that adolescents have the support of their teachers, parents, and physicians at this transitional time in their lives. Even though sexual education is taught in our school systems, these students are inadequately prepared and a staggering number of students are exposed to sexually transmitted infections and teen pregnancy; not to mention the emotional distress that adolescents will endure.It takes years for the average adolescents’ body to go through the process of sexual maturation. The onset of puberty is not triggered by any particular event, but rather a multitude of things such as stress, genetics, nutrition and diet as well as the amount of body fat to name a few (Gentry, p. 1, 2002). There is also a growth spurt that is brought on by puberty when the skeletal system grows rapidly. This can occur in girls starting at age 10 and boy at age 10.5; this growth spurt usually ends around 19 for girls and 20 for boys (Headlee, p. 7, 2010). Hands legs and feet are first and then the growth spurt will hit the torso; in girls, the sexual hormone will attribute to broader hips. These growths spurts can be an awkward time for adolescent children as their bodies are evening out.
