For example, a 1999 study by the Guttmacher Institute found that most U.S. sex education courses in grades 6 through 12 cover puberty, HIV, STDs, abstinence, implications of teenage pregnancy, and how to resist peer pressure.n 2010, Congress eliminated two federal programs that had funded abstinence-only education; the Adolescent Family Life (AFL) Prevention program and the Community-Based Abstinence Education (CBAE) program; $13 million and $99 million a year, respectively for a total of $112 million a year.
