The original submission said: "This term is found in books and articles written by sex education researchers in Japan to translate the American term "abstinence-only sex education."  For example, see the book published in 2003 titled アメリカの禁欲主義教育と日本の性問題, edited by 日本家族計画協会, 家族計画国際協力財団, ジョイセフ, "人間と性”教育研究協議会 and, ぷれいす東京.

Yes, obviously rather a euphemism.  It would be nice to record it somewhere, but I agree it's not really a term in the Japanese lexicon.
