e. Making contraceptives available to teenagers through school clinics will encourage them to be more sexually active because they will not have to worry about unwanted pregnancy.
Moore and Caldwell, in a review of the relevant studies, argue that, if anything, this practice reduced the level of teenage sexual activity and significantly reduced the level of teenage pregnancy.
They argue that where teenagers are better informed about sex they are less inclined to either indulge in sexual activity out of curiosity / ignorance or are more willing to limit their sexual behaviour.
