Contraception (or birth control) refers to techniques, drugs, or devices that prevent conception. There are many different methods, each having its own level of effectiveness and safety. According to a study in the JAMA Psychiatry journal, hormonal birth control is associated with depression.[1] The only known method that is 100% effective is abstinence. Abstinence during fertile times can take the place of artificial forms of birth control.[2]
The Roman Catholic church prohibits the use of artificial contraceptives such as pills or barriers to Catholics, though it supports natural methods of avoiding conception based on timing. The policy on contraception is given in the Humanae Vitae.
The Anglican Church regards sexual love as an essential way for a husband and wife to express and strengthen their mutual love, citing Genesis 2:18 'It is not good that the man (Adam) should be alone' in support of this. At the Lambeth Conference of 1930 a resolution was passed stating: Where there is a clearly felt moral obligation to limit or avoid parenthood, complete abstinence is the primary and obvious method. It continued by saying that if there was morally sound reasoning for avoiding abstinence, the Conference agrees that other methods may be used, provided that this is done in the light of Christian principles.
However, by the Lambeth Conference of 1958, contraceptive use among most Anglicans was widespread and a resolution that year stated that the responsibility for deciding upon the number and frequency of children was laid by God upon the consciences of parents in such ways as are acceptable to husband and wife.[5]
There is no single attitude to contraception within Islam; however eight of the nine classic schools of Islamic law permit it.
But some Islamic leaders have openly campaigned against the use of condoms or other birth control methods, thus making population planning in many countries ineffective.
This resistance to birth control was reflected in 2005 when a conference involving 40 Islamic scholars from 21 countries urged fresh efforts to push population planning and better reproductive health services.
Hinduism encourages procreation within marriage, yet there is no opposition against contraception. Most Hindus accept that there is a duty to have a family during that stage of one's life. So they are unlikely to use birth control to avoid having children altogether.
Traditional Hindu texts praise large families (which was normal in ancient times). Yet, Hindu scriptures that applaud small families also exist which emphasize the development of a positive social conscience. So family planning is seen as an ethical good. The Upanishads (texts delineating key Hindu concepts) describe birth control methods, and some Hindu scriptures contain advice on what a couple should do to promote conception (thus providing a type of contraceptive advice).
Some types of contraception can produce an increase in the risk of breast cancer among current and recent users. By 1999, the World Health Organization (WHO) determined the scientific evidence was then compelling enough to designate combined estrogen-progestogen oral contraceptives as "carcinogenic to humans" (Group 1). This designation was reaffirmed in 2005.[6]
Studies accounting for the timing and length of exposure showed that women who began using hormonal contraceptives before the age of 20 and before their first full-term pregnancy are at substantially increased risk for premenopausal breast cancer.
The most recent meta-analysis to date, published in the Mayo Clinic Proceedings (October,2006) found that oral contraceptives increase the risk of developing premenopausal breast cancer by 44% in women who took them prior to the birth of their first child. The authors noted that 21 out of 23 studies showed a positive trend or risk in this cohort of women. The meta-analysis also found that women who took oral contraceptives for 4 or more years prior to the birth of their first child had a 52% increased risk of developing premenopausal breast cancer. Both of these statistics were significant at the 99% confidence interval-a higher standard of statistical significance than is used in most research.[7] An older pooled analysis published in 1996-the Oxford pooled-analysis- found a relative risk (RR) of 1.24 of breast cancer diagnosis among current combined oral contraceptive pill users;[8] however this analysis has been critiqued because over 66% of women were over the age of 45 [9] and because the authors included several older studies, the bulk of whose data came prior to 1980.[10]
Until a 1923 court decision, the federal Comstock Act prohibited the use of the mail service to distribute contraceptives or information on contraception or abortion. Contraception was until this time considered obscene for legal purposes, as it was considered to serve only in the promotion of immorality.
Until 1965, some US states criminalized the possession and/or distribution of contraceptives for reasons of public morality on the grounds that contraception would encourage premarital sex. In the 1965 Supreme Court case of Griswold v. Connecticut, activist judges invented a constitutional right to contraception. The 1972 case of Eisenstadt v. Baird later extended this invented right to include even unmarried couples, rendering any legal attempt to restrict access impossible.
John Roberts upheld "Griswold" at his 2005 confirmation hearings to be Chief Justice.[11]
