Modern methods :
In 1909, Richard Richter developed the first intrauterine device made from silkworm gut, which was further developed and marketed in Germany by Ernst Gräfenberg in the late 1920s. Gregory Pincus"Pincus and John Rock with help from the Planned Parenthood Federation of America developed the first birth control pills in the 1950s, such as mestranol / norethynodrel, which became publicly available in the 1960s. Medical abortion became an alternative to surgical abortion with the availability of prostaglandin analogs in the 1970s and mifepristone in the 1980s.

Legal positions :
Human rights agreements require most governments to provide family planning and contraceptive information and services. These include the requirement to create a national plan for family planning services, remove laws that limit access to family planning, ensure that a wide variety of safe and effective birth control methods are available including emergency contraceptives, make sure there are appropriately trained healthcare providers and facilities at an affordable price, and create a process to review the programs implemented. If governments fail to do the above it may put them in breach of binding international treaty obligations.
In America, Griswold v. Connecticut overturned a state law prohibiting dissemination of contraception information based on a constitutional right to privacy for marital relationships. In 1971, Baird extended this right to privacy to single people.
In 2010, the United Nations launched the Every Woman Every Child movement to assess the progress toward meeting women's contraceptive needs. The initiative has set a goal of increasing the number of users of modern birth control by 120 million women in the world's 69 poorest countries by the year 2020. Additionally, they aim to eradicate discrimination against girls and young women who seek contraceptives. The American Congress of Obstetricians and Gynecologists(ACOG) recommended in 2014 that oral birth control pills should be over the counter medications.

Religious views:
Religions vary widely in their views of the ethics of birth control. The Roman Catholic Church officially only acceptsnatural family planning in certain cases, although large numbers of Catholics in developed countries accept and use modern methods of birth control. Among Protestants there is a wide range of views from supporting none to allowing all methods of birth control. Views in Judaism range from the stricter Orthodox sect to the more relaxed Reformsect. Hindus may use both natural and artificial contraceptives. A common Buddhist view is that preventing conception is acceptable, while intervening after conception has occurred is not.
In Islam, contraceptives are allowed if they do not threaten health, although their use is discouraged by some. The Quran does not make any explicit statements about the morality of birth control, but contains statements encouraging having children. Muhammad also is reported to have said "marry and procreate".
