Not personally. Someone from the Institute said it <http://www.nytimes.com/library/national/science/042999sci-teen-births.html>:
< quote> "Many groups want to take credit for the drop in teen-age pregnancy, but the credit truly goes to the teen-agers," said Jacqueline E. Darroch, the [Alan Guttmacher] institute's vice president, in a statement accompanying a study to be released Thursday. "About 20 percent of the decrease since the late 1980s is because of decreased sexual activity, and 80 percent of the decrease is because of more effective contraceptive practice." </quote>
