[Ed. – So will California find some other rationale for teaching young children about fisting, blood play, and oral sex?]
A global research review of school based comprehensive sex education programs found very little effectiveness from these programs and instead found increased sexual activity.
The review, conducted by the Institute for Research & Evaluation and published in the Institute of Law and Medicine in January, examined 60 studies of 40 school based comprehensive sex education programs in the U.S. as well as 43 studies of 39 programs in other countries.
The review found “little evidence that [comprehensive sex education] programs are effective at producing positive impact on their participants” and questioned the efficacy of school based comprehensive sex education, according to a press release from the Institute for Research and Evaluation.
… [T]he review also found no evidence that these six programs increased consistent condom usage or teen abstinence or reduced sexually transmitted diseases.
