" The “sugar daddies” program simply informed students about what kind of people are more likely to be infected. Its effect was to sharply cut down sex with older men (the “sugar daddies”) but, also interestingly, to promote protected sex with boys their own age. After a year, the pregnancy rates were 5.5 percent in schools that had not received the program and 3.7 percent in schools that had received it. This reduction was mainly attributable to a reduction by two-thirds in pregnancies where an older male partner was involved. "
