I believe the charities have been incubated based on health economic evidence showing that they reduce negative health outcomes associated from unplanned pregnancies, presumably by preventing them, which should also reduce abortions.
Characteristics of the specific programs (setting, baseline effects, low-cost approaches etc) might make them more cost-effective than the average contraception / sex-ed program. Also, programs may be cost-effective despite small effects on abortion rates due to low costs.
