<unk>  are legal<unk>  and freedoms relating to reproduction and<unk>  health that vary amongst countries around the world. The World Health Organization defines<unk>  as follows:<unk>  rest on the recognition of the basic<unk> of all couples and individuals to decide freely and responsibly the number, spacing and timing of their children and to have the information and means to do so, and the<unk> to attain the highest standard of sexual and<unk>  health. They also include the<unk> of all to make decisions concerning reproduction free of discrimination, coercion and violence. Women's<unk>  may include some or all of the following: abortion-rights movements; birth control; freedom from coerced sterilization and contraception; the<unk> to access good-quality<unk>  healthcare; and the<unk> to education and access in order to make free and informed<unk>  choices.<unk>  may also include the<unk> to receive education about sexually transmitted infections and other aspects of sexuality,<unk> to menstrual health and protection from practices such as female genital mutilation (FGM).<unk>  began to develop as a subset of human<unk>  at the United Nation's 1968 International Conference on Human<unk> . The resulting non-binding Proclamation of Tehran was the first international document to recognize one of these<unk>  when it stated that: "Parents have a basic human<unk> to determine freely and responsibly the number and the spacing of their children." Women’s sexual, gynecological, and mental health issues were not a priority of the United Nations until its Decade of Women (1975–1985) brought them to the forefront. States, though, have been slow in incorporating these<unk>  in internationally legally binding instruments. Thus, while some of these<unk>  have already been recognized in hard law, that is, in legally binding international human<unk>  instruments, others have been mentioned only in non binding recommendations and, therefore, have at best the status of soft law in international law, while a further group is yet to be accepted by the international community and therefore remains at the level of advocacy. Issues related to<unk>  are some of the most vigorously contested<unk> ' issues worldwide, regardless of the population's socioeconomic level, religion or culture. The issue of<unk>  is frequently presented as being of vital importance in discussions and articles by population concern organizations such as Population Matters.<unk>  are a subset of sexual and<unk>  health and<unk> .
