Natural family planning (NFP) comprises the family planning methods approved by the Catholic Church and some Protestant denominations for both achieving and postponing or avoiding pregnancy. [1] [2] In accordance with the Church's teachings regarding sexual behavior, NFP excludes the use of other methods of birth control, which it refers to as "artificial contraception".

Contents

Periodic abstinence, the crux of NFP, is deemed moral by the Church for avoiding or postponing pregnancy for just reasons. [3] When used to avoid pregnancy, couples may engage in sexual intercourse during a woman's naturally occurring infertile times such as during portions of her ovulatory cycle. Various methods may be used to identify whether a woman is likely to be fertile; this information may be used in attempts to either avoid or achieve pregnancy.

Effectiveness can vary widely, depending on the method used, whether the users were trained properly, and how carefully the couple followed the protocol. Pregnancy can result in up to 25% of the user population per year for users of the symptoms-based or calendar-based methods, depending on the method used and how carefully it was practised.

Natural family planning has shown very weak and contradictory results in pre-selecting the sex of a child, with the exception of a Nigerian study at odds with all other findings. Because of these remarkable results, an independent study needs to be repeated in other populations. [4] [5]

History

Pre-20th century

In ancient history, some Christian writers were against abstinence to prevent childbirth and some allowed it. Possibly the earliest Christian writing about periodic abstinence was by Clement of Alexandria. He wrote, "Let the Educator (Christ) put us to shame with the word of Ezekiel: 'Put away your fornications' [Eze. 43:9]. Why, even unreasoning beasts know enough not to mate at certain times. To indulge in intercourse without intending children is to outrage nature, whom we should take as our instructor." [6]

In the year 388, St. Augustine wrote against the Manichaeans: "Is it not you who used to counsel us to observe as much as possible the time when a woman, after her purification, is most likely to conceive, and to abstain from cohabitation at that time...?" [7] The Manichaeans (the group the early church father St. Augustine wrote of and considered to be heretics) believed that it was immoral to create any children, thus (by their belief system), trapping souls in mortal bodies. Augustine condemned them for their use of periodic abstinence during fertile periods: "From this it follows that you consider marriage is not to procreate children, but to satiate lust." [8] : 120  About the year 401, St. Augustine wrote "Of the Good of Marriage" in which he affirmed married couples have the option of having sex without either of them intending procreation: "For, whereas that natural use, when it pass beyond the compact of marriage, that is, beyond the necessity of begetting, is pardonable in the case of a wife, damnable in the case of an harlot; that which is against nature is execrable when done in the case of an harlot, but more execrable in the case of a wife." [9]

Saint Thomas Aquinas wrote in his Summa Contra Gentiles: "Hence it is clear that every emission of the semen is contrary to the good of man, which takes place in a way whereby generation is impossible; and if this is done on purpose, it must be a sin. I mean a way in which generation is impossible in itself as is the case in every emission of the semen without the natural union of male and female: wherefore such sins are called 'sins against nature.' But if it is by accident that generation cannot follow from the emission of the semen, the act is not against nature on that account, nor is it sinful; the case of the woman being barren would be a case in point." [10]

Protestant Reformers such as Martin Luther and John Calvin were opposed to unnatural birth control. [11] Centuries later, John Wesley, the leader of the Methodist movement said that unnatural birth control could destroy one's soul. [11]

If the Manichaeans had an accurate idea of the fertile portion of the menstrual cycle, such knowledge died with them. [12] Documented attempts to prevent pregnancy by practicing periodic abstinence do not appear again until the mid-19th century, when various calendar-based methods were developed "by a few secular thinkers". [13] The Roman Catholic Church's first recorded official approval of periodic abstinence from 1853, where a ruling of the Church's Sacred Penitentiary addressed the topic. Distributed to confessors, the ruling stated that couples who had, on their own, begun the practice of periodic abstinence—if they had "grave reasons"—were not sinning by doing so. [14]

In the Catholic Church, a grave/significant reason for using NFP can include social, economical, medical and other analogous reasons that may motivate a couple to practise it to postpone pregnancy. [15] The Church holds that the motivations behind NFP should not be selfish or self-centered. [15]

In 1880, the Sacred Penitentiary reaffirmed the 1853 ruling and went slightly further. It suggested that, in cases where the couple was already practising artificial birth control and could not be dissuaded to cease attempting birth regulation, the confessor might morally teach them of periodic abstinence. [14]

Early 20th century

In 1905, Theodoor Hendrik van de Velde, a Dutch gynecologist, showed that women only ovulate once per menstrual cycle. [16] In the 1920s Japanese gynecologist Kyusaku Ogino and Austrian Hermann Knaus independently made the discovery that ovulation occurs about fourteen days before the next menstrual period. [17] Ogino used his discovery to develop a formula for use in aiding infertile women to time intercourse to achieve pregnancy.

In 1930, John Smulders, a Roman Catholic physician from the Netherlands, used Knaus and Ogino's discoveries to create the rhythm method. Smulders published his work with the Dutch Roman Catholic medical association, and this was the official rhythm method promoted over the next several decades. [17] While maintaining procreation as the primary function of intercourse, the December 1930 encyclical Casti connubii by Pope Pius XI gave recognition to a secondary—unitive—purpose of sexual intercourse. This encyclical stated that there was no moral stain associated with having marital intercourse at times when "new life cannot be brought forth". This referred primarily to conditions such as current pregnancy and menopause. [18] In 1932, a Catholic physician published a book titled The Rhythm of Sterility and Fertility in Women describing the method, [13] and the 1930s also saw the first U.S. Rhythm Clinic (founded by John Rock) to teach the method to Catholic couples. [19] It was during this decade that Rev. Wilhelm Hillebrand, a Catholic priest in Germany, developed a system for avoiding pregnancy based on basal body temperature. [20]

Since 20th century

A minority of Catholic theologians continued to doubt the morality of periodic abstinence. [14] Some historians consider two speeches delivered by Pope Pius XII in 1951 [21] to be the first unequivocal acceptance of periodic abstinence by the Catholic Church. [13] The 1950s also saw another major advance in fertility awareness knowledge: Dr. John Billings discovered the relationship between cervical mucus and fertility while working for the Melbourne Catholic Family Welfare Bureau. Billings and several other physicians studied this sign for a number of years, and by the late 1960s had performed clinical trials and begun to set up teaching centers around the world. [22]

The Vatican II Constitution on the Church in the Modern World declared: "While not making the other purposes of matrimony of less account, the true practice of conjugal love, and the whole meaning of the family life which results from it, have this aim: that the couple be ready with stout hearts to cooperate with the love of the Creator and the Savior. Who through them will enlarge and enrich His own family day by day" (50). Beyond that the council of bishops was told to leave to the Pontifical Commission on Birth Control the task of advising Pope Paul VI on the issue. 64 of the 68 Commission members who voted recommended allowing other means of contraception, but Paul VI determined otherwise. [23]

Humanae Vitae , published in 1968 by Pope Paul VI, addressed a pastoral directive to scientists: "It is supremely desirable... that medical science should by the study of natural rhythms succeed in determining a sufficiently secure basis for the chaste limitation of offspring." This is interpreted as favoring the then-new, more reliable symptoms-based fertility awareness methods over the rhythm method. Just a few years later, in 1971, the first organization to teach a symptothermal method, using both mucus and temperature observations, was started. Now called Couple to Couple League International, this organization was founded by John and Sheila Kippley, lay Catholics, along with Dr. Konald Prem. [20] During the following decade, other now-large Catholic organizations were formed: Family of the Americas(1977), [24] and the Creighton Model as part of the Pope Paul VI Institute (1985), [25] both mucus-based systems of NFP.

Use of the term natural family planning to describe calendar-based methods is considered incorrect by the United States Conference of Catholic Bishops, which considers such methods "inaccurate". [26] Some organizations have considered calendar-based methods to be forms of NFP. [27] : 154  For example, in 1999 the Institute for Reproductive Health at Georgetown University developed the Standard Days Method (SDM), which is more effective than the rhythm method. [28] SDM is promoted by Georgetown University as a form of natural family planning. [29] [30]

Prevalence

It is estimated that 2%–3% of the world's reproductive age population relies on periodic abstinence to avoid pregnancy. [31] However, what portion of this population should be considered NFP users is unclear. Some Catholic sources consider couples that violate the religious restrictions associated with natural family planning to not be NFP users. [27] : 13  [32]

There is little data on the worldwide use of natural family planning. In Brazil, NFP is the third most popular family planning method. [33] The "safe period" method of fertility awareness is the most common family planning method used in India, although condoms are used by some. [34] Of all American women surveyed nationally in 2002, only 0.9% were using "periodic abstinence" (defined as "calendar rhythm" and "natural family planning") compared to 60.6% using other contraceptive methods. [35] In Italy, where the vast majority of citizens claims to be Catholic, NFP methods are rarely taught. [36] [ better source needed ]

In 2002, Sam and Bethany Torode, then a Protestant Christian couple, published a book advocating NFP use. [37] [38] Many NFP clinics and teaching organizations are associated with the Catholic Church, as well as the Church of Jesus Christ of Latter-day Saints (LDS Church) [39] and some members of the Muslim faith. [40]

Some fundamental Christians espouse Quiverfull theology, eschewing all forms of birth control, including natural family planning. [41]

Contraception

Some proponents of NFP differentiate it from other forms of birth control by labeling them artificial birth control. [42] [43] Other NFP literature holds that natural family planning is distinct from contraception. [44] [45] [46] Proponents justify this classification system by saying that NFP has unique characteristics not shared by any other method of birth regulation except for abstinence. NFP is open to life, [43] [46] it alters neither the fertility of the woman nor the fecundity of a particular sex act. [44] [45] That NFP can be used to both avoid or achieve pregnancy. [47]

The Catholic Church has often said that it considers the use of contraception not to conform with God's will for Catholic marriage, in that it interrupts the procreative aspect of the sexual union, making it unnatural and counter to what God has outlined for married couples. [48] Pope John Paul II said in Love and Responsibility that an integral aspect of the love between husband and wife is the openness to the real potential of becoming a parent, or becoming a parent of another, whenever the spouses give of themselves in the sexual embrace. [49] Edward Sri makes an additional commentary on Love and Responsibility in Men, Women, and the Mystery of Love, claiming the openness to life within marriage bolsters an emotional intimacy to supplement physical intimacy. [50]

These claims about how contraception can negatively impact fidelity within marriage are supported by a 2021 study in of more than 2,000 married women, some of whom practised NFP within their marriage and some who practised contraception. The study found that women who practised NFP were 58% less likely than their peers who used contraception to get divorced. "Although there are lower odds of divorce among NFP users, the reason might be due to their religiosity." [51]

Methods

There are three main types of NFP: the symptoms-based methods, the calendar-based methods, and the breastfeeding or lactational amenorrhea method. Symptoms-based methods rely on biological signs of fertility, while calendar-based methods estimate the likelihood of fertility based on the length of past menstrual cycles.

Clinical studies by the Guttmacher Institute found that periodic abstinence resulted in a 25.3 percent failure under typical conditions, though it did not differentiate between symptom-based and calendar-based methods. [52]

Symptoms-based

Some methods of NFP track biological signs of fertility. When used outside of the Catholic concept of NFP, these methods are often referred to simply as fertility awareness-based methods rather than NFP. [53] The three primary signs of a woman's fertility are her basal body temperature (BBT), her cervical mucus, and her cervical position. [54] Computerized fertility monitors, such as Lady-Comp, may track basal body temperatures, hormonal levels in urine, changes in electrical resistance of a woman's saliva, or a mixture of these symptoms. [55]

From these symptoms, a woman can learn to assess her fertility without use of a computerized device. Some systems use only cervical mucus to determine fertility. Two well-known mucus-only methods are the Billings ovulation method and the Creighton Model FertilityCare System. If two or more signs are tracked, the method is referred to as a symptothermal method. Two popular symptothermal systems are taught by the Couple to Couple League and the Fertility Awareness Method (FAM) with Toni Weschler. A study completed in Germany in 2007 found that the symptothermal method has a method effectiveness of 99.6%. [56]

A study by the World Health Organization involving 869 fertile women from Australia, India, Ireland, the Philippines, and El Salvador found that 93% could accurately interpret their body's signals regardless of education and culture. [57]

A symptohormonal method of NFP developed at Marquette University uses the ClearBlue Easy fertility monitor and cycle history to determine the fertile window. [58] The monitor measures estrogen and LH to determine the peak day. This method is also applicable during postpartum, breastfeeding, and perimenopause, and requires less abstinence than other NFP methods. [59] Some couples prefer this method because the monitor reading is objective and is not affected by sleep quality as BBT can be.

Calendar-based

Calendar-based methods determine fertility based on a record of the length of previous menstrual cycles. They include the Rhythm Method and the Standard Days Method. The Standard Days method was developed and proven by the researchers at the Institute for Reproductive Health of Georgetown University. CycleBeads, unaffiliated with religious teachings, is a visual tool based on the Standard Days method. According to the Institute of Reproductive Health, when used as birth control, CB has a 95% effectiveness rating. Computer programs are available to help track fertility on a calendar. [60]

Lactational amenorrhea

The lactational amenorrhea method (LAM) is a method of avoiding pregnancy based on the natural postpartum infertility that occurs when a woman is amenorrheic and fully breastfeeding. The rules of the method help a woman identify and possibly lengthen her infertile period.

Debates

Roderick Hindery reported that a number of Western Catholics have voiced significant disagreement with the Church's stance on contraception. [61] In 1968, the Canadian Conference of Catholic Bishops issued what many interpreted as a dissenting document, the Winnipeg Statement, in which the bishops recognized that a number of Canadian Catholics found it "either extremely difficult or even impossible to make their own all elements of this doctrine" (that of Humanae vitae ). [62] Additionally, in 1969, they reasserted the Catholic principle of primacy of conscience, [62] a principle that they said should be properly interpreted. They insisted that "a Catholic Christian is not free to form his conscience without consideration of the teaching of the magisterium , in the particular instance exercised by the Holy Father in an encyclical letter." [63] Catholics for a Free Choice claimed in 1998 that 96% of U.S. Catholic women had used contraceptives at some point in their lives and that 72% of U.S. Catholics believed that one could be a good Catholic without obeying the Church's teaching on birth control. [64] According to a nationwide poll of 2,242 U.S. adults surveyed online in September 2005 by Harris Interactive (they stated that the magnitude of errors cannot be estimated due to sampling errors, non-response, etc.), 90% of U.S. Catholics supported the use of birth control/contraceptives. [65] A survey conducted in 2015 by the Pew Research Center among 5,122 U.S. adults (including 1,016 self-identified Catholics) stated 76% of U.S. Catholics thought that the Church should allow Catholics to use birth control. [66]

In 2003, the BBC's Panorama claimed that Church officials have taught that HIV can pass through the membrane of the latex rubber from which condoms were made. It was considered not true according to the World Health Organization, [67] despite a 2000 report by the National Institutes of Health (NIH) stating that consistent use of latex condoms reduced the risk of HIV transmission by approximately 85% relative to risk when unprotected, [68] not 100% safe.

In an interview on Dutch television in 2004, Belgian Cardinal Godfried Danneels argued that the use of condoms should be supported to prevent AIDS if sex with a person infected with HIV should take place, though it is to be avoided. According to Danneels, "the person must use a condom in order not to disobey the commandment condemning murder, in addition to breaking the commandment which forbids adultery. ... Protecting oneself against sickness or death is an act of prevention. Morally, it cannot be judged on the same level as when a condom is used to reduce the number of births." [69] In 2009, Pope Benedict XVI asserted that handing out condoms is not the solution to combating AIDS and actually makes the problem worse. He proposed "spiritual and human awakening" and "friendship for those who suffer" as solutions. [70]

Artificial family planning proponent Stephen D. Mumford claimed that the primary motivation behind the Church's continued opposition to contraceptive use is the impossibility to make changes without spoiling papal authority with regards to papal infallibility. [71] Mumford gives as an example the citation made by dissident theologian August Bernhard Hasler of a minority report co-authored by Pope John Paul II prior to his papacy:

If it should be declared that contraception is not evil in itself, then we should have to concede frankly that the Holy Spirit had been on the side of the Protestant churches in 1930 (when the encyclical Casti connubii was promulgated), in 1951 (Pius XII's address to the midwives), and in 1958 (the address delivered before the Society of Hematologists in the year the pope died). It should likewise have to be admitted that for a half century the Spirit failed to protect Pius XI, Pius XII, and a large part of the Catholic hierarchy from a very serious error. This would mean that the leaders of the Church, acting with extreme imprudence, had condemned thousands of innocent human acts, forbidding, under pain of eternal damnation, a practice which would now be sanctioned. The fact can neither be denied nor ignored that these same acts would now be declared licit on the grounds of principles cited by the Protestants, which popes and bishops have either condemned or at least not approved. [72]

It is said that none of the instances cited falls under the domain of papal infallibility; the Pope is not considered infallible except in the rare, solemn occasions when he is speaking ex cathedra. [73] According to M. R. Gagnebet, though the encyclical Humanae vitae is considered by some to be a non-infallible document, "the doctrinal authority of the Pope and the Bishops is not limited to infallible teaching. The duty of obedience is not restricted to definitions of faith". [74]

Theological opposition has come from some denominations of Protestant Christianity. The Reformed theologian John Piper's Desiring God ministry states of NFP, "There is no reason to conclude that natural family planning is appropriate but that 'artificial' (non-abortive) means are not." [75] Eastern Orthodox couple Sam and Bethany Torode, former advocates of NFP-only, have redacted their position to include barrier methods and explain their current theology this way:

We also see honest congruity with the language of the body by saying "no" to conception with our bodies (via barrier methods or sensual massage) when our minds and hearts are also saying "no" to conception. We don't believe this angers God, nor that it leads to the slippery slope of relativism or divorce. We strongly disagree with the idea that this is a mortal sin.... It's a theological attack on women to always require that abstinence during the time of the wife's peak sexual desire (ovulation) for the entire duration of her fertile life, except for the handful of times when she conceives. [76]

Traditionalist Catholic priest Francis Ripley criticizes the concept: [77]

The use of the term "Natural Family Planning" has come under sharp attack from traditional Catholic writers in recent years because it implies the right of the couple to "plan" their family; whereas the Catholic norm is to let God plan one's family and to accept the children when (and if) God gives them—as a blessing from Him on the marital union and on society. [77]

<span class="mw-page-title-main">Fertility awareness</span> Methods to determine menstrual phases

Fertility awareness (FA) refers to a set of practices used to determine the fertile and infertile phases of a woman's menstrual cycle. Fertility awareness methods may be used to avoid pregnancy, to achieve pregnancy, or as a way to monitor gynecological health.

Calendar-based methods are various methods of estimating a woman's likelihood of fertility, based on a record of the length of previous menstrual cycles. Various methods are known as the Knaus–Ogino method and the rhythm method. The standard days method is also considered a calendar-based method, because when using it, a woman tracks the days of her menstrual cycle without observing her physical fertility signs. The standard days method is based on a fixed formula taking into consideration the timing of ovulation, the functional life of the sperm and the ovum, and the resulting likelihood of pregnancy on particular days of the menstrual cycle. These methods may be used to achieve pregnancy by timing unprotected intercourse for days identified as fertile, or to avoid pregnancy by avoiding unprotected intercourse during fertile days.

<span class="mw-page-title-main">Sexual abstinence</span> Act of refraining from sexual activity

Sexual abstinence or sexual restraint is the practice of refraining from sexual activity for medical, psychological, legal, social, philosophical, moral, religious or other reasons. Sexual abstinence is distinct from asexuality, which is a sexual orientation where people feel small or no sexual attraction. Celibacy is sexual abstinence generally motivated by factors such as an individual's personal or religious beliefs. Sexual abstinence before marriage is required in some societies by social norms, or by law in some countries. It is a part of chastity.

Casti connubii is a papal encyclical promulgated by Pope Pius XI on 31 December 1930 in response to the Lambeth Conference of the Anglican Communion. It stressed the sanctity of marriage, prohibited Catholics from using any form of artificial birth control, and reaffirmed the prohibition on abortion. It also explained the authority of church doctrine on moral matters, and advocated that civil governments follow the lead of the church in this area.

The Billings ovulation method is a method in which women use their vaginal mucus to determine their fertility. It does not rely on the presence of ovulation, rather it identifies patterns of potential fertility and obvious infertility within the cycle, whatever its length. Effectiveness, however, is not very clear.

Prior to the 20th century, the three major branches of Christianity—Catholicism, Eastern Orthodoxy and Protestantism —generally held a critical perspective of birth control. Among Christian denominations today, however, there is a large variety of views regarding birth control that range from the acceptance of birth control to only allowing natural family planning to teaching Quiverfull doctrine, which disallows contraception and holds that Christians should have large families.

The Creighton Model FertilityCare System is a form of natural family planning which involves identifying the fertile period during a woman's menstrual cycle. The Creighton Model was developed by Thomas Hilgers, the founder and director of the Pope Paul VI Institute. This model, like the Billings ovulation method, is based on observations of cervical mucus to track fertility. Creighton can be used for both avoiding pregnancy and achieving pregnancy.

Contraception was illegal in Ireland from 1935 until 1980, when it was legalised with strong restrictions, later loosened. The ban reflected Catholic teachings on sexual morality.

<span class="mw-page-title-main">Comparison of birth control methods</span>

There are many methods of birth control that vary in requirements, side effects, and effectiveness. As the technology, education, and awareness about contraception has evolved, new contraception methods have been theorized and put in application. Although no method of birth control is ideal for every user, some methods remain more effective, affordable or intrusive than others. Outlined here are the different types of barrier methods, hormonal methods, various methods including spermicides, emergency contraceptives, and surgical methods and a comparison between them.

The Jewish view on birth control currently varies between the Orthodox, Conservative and Reform branches of Judaism. Among Orthodox Judaism, use of birth control has been considered only acceptable for use in limited circumstances. Conservative Judaism, while generally encouraging its members to follow the traditional Jewish views on birth control has been more willing to allow greater exceptions regarding its use to fit better within modern society. Reform Judaism has generally been the most liberal with regard to birth control allowing individual followers to use their own judgment in what, if any, birth control methods they might wish to employ.

Religious adherents vary widely in their views on birth control. This can be true even between different branches of one faith, as in the case of Judaism and Christianity. Some religious believers find that their own opinions of the use of birth control differ from the beliefs espoused by the leaders of their faith, and many grapple with the ethical dilemma of what is conceived as "correct action" according to their faith, versus personal circumstance, reason, and choice. This article will discuss various views on birth control of the major world religions Christianity, Buddhism, Judaism, Islam, Hinduism, and Baha'i.

Catholic theology of sexuality, like Catholic theology in general, is drawn from "natural law", canonical scripture, divine revelation, and sacred tradition, as interpreted authoritatively by the magisterium of the Catholic Church. Sexual morality evaluates sexual behavior according to standards laid out by Catholic moral theology, and often provides general principles by which Catholics can evaluate whether specific actions meet these standards.

<span class="mw-page-title-main">Birth control</span> Method of preventing human pregnancy

Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent unintended pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using human birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable.

Religious response to assisted reproductive technology deals with the new challenges for traditional social and religious communities raised by modern assisted reproductive technology. Because many religious communities have strong opinions and religious legislation regarding marriage, sex and reproduction, modern fertility technology has forced religions to respond.

Protestant views on contraception are markedly more pluralistic than the doctrine expressed by the Magisterium of the Roman Catholic Church, due to historical divergences of theological thought that began during the Protestant Reformation, including the rejection of an infallible doctrinal authority other than Scripture. The doctrine of various forms of Protestantism as a whole from the Reformation until 1930 strongly condemned contraception as the Catholic Church does, but such opposition has since almost totally been dropped. Since the 1940 Seventh Lambeth Conference of the Anglican Communion, major mainline Protestant denominations shifted their doctrine to accepting contraception. In general, most liberal Protestants, such as the United Church of Christ, hold relatively settled views that accept the use of contraception, while conservative evangelicals denominations mostly also accept the use of contraception; however, some evangelicals are divided on the issue, with a small minority of denominations seeing natural family planning as the only permissible method. Other traditions such as Laestadian Lutheran Churches, do not permit the use of birth control and may teach Quiverfull doctrine, which holds that Christians should have large families.

Contraception in Francoist Spain (1939–1975) and the democratic transition (1975–1985) was illegal. It could not be used, sold or covered in information for dissemination. This was partly a result of Hispanic Eugenics that drew on Catholicism and opposed abortion, euthanasia and contraception while trying to create an ideologically aligned population from birth. A law enacted in 1941 saw usage, distribution and sharing of information about contraception become a criminal offense. Midwives were persecuted because of their connections to sharing contraceptive and abortion information with other women. Condoms were somewhat accessible in the Francoist period despite prohibitions against them, though they were associated with men and prostitutes. Other birth control practices were used in the 1950s, 1960s and 1970s including diaphragms, coitus interruptus, the pill, and the rhythm method. Opposition to the decriminalization of contraception became much more earnest in the mid-1960s. By 1965, over 2 million units of the pill had been sold in Spain where it had been legal under certain medical conditions since the year before. Despite the Government welcoming the drop in the number of single mothers, they noted in 1975 that this was a result of more women using birth control and seeking abortions abroad.
