When sex education is contentiously debated, the chief controversial points are whether covering child sexuality is valuable or detrimental; whether LGBT sex education should be integrated into the curriculum; the use of birth control such as condoms and hormonal contraception; and the impact of such use on pregnancy outside marriage, teenage pregnancy, and the transmission of STIs. Increasing support for abstinence-only sex education by conservative groups has been one of the primary causes of this controversy. Countries with conservative attitudes towards sex education (including the UK and the U.S.) have a higher incidence of STIs and teenage pregnancy."Joy of sex education" by George Monbiot , The Guardian, May 11, 2004 On the other hand, it seems that in countries where sex education is not part of the curriculum, students show limited knowledge even in basic reproductive issues. For example, in a 2019 study with Greek students, it is reported that about two-thirds of the students failed to name external female genitals, such as the clitoris and labia, even after detailed pictures were provided to them.
