Sex education, also known as sexual education, sexuality education or sex ed, is the instruction of issues relating to human sexuality, including human sexual anatomy, sexual activity, sexual reproduction, safe sex and birth control, sexual health, reproductive health, emotional relations and responsibilities, age of consent, and reproductive rights. Sex education that includes all of these issues is known as comprehensive sex education, and is often opposed to abstinence-only sex education, which only focuses on sexual abstinence. Sex education may be provided as part of school programs, public health campaigns, or by parents or caregivers. In some countries it is known as "Relationships and Sexual Health Education". Many governments see it as beneficial to provide public education on such matters prior to or at the beginning of puberty for reasons of public health, in limiting the spread of sexually transmitted infections, and avoiding teenage pregnancy or unwanted pregnancies later on.
