To some, the Catholic Church's consistent teaching againstbirth control may seem outdated. Yet with each passing year, evidence of contraception's
negative consequences keeps piling up, revealing profound repercussions on women,
children, families, and society.
Contraceptives Can Cause Early
Advocates of contraception claim it
doesn't cause abortions. However, that claim rests on an inaccurate
redefinition of "pregnancy" as beginning only after an embryo successfully implants in the mother's uterus. This,
then, excludes from the meaning of abortion all pills and devices that cause
the death of an embryo before
implantation. Yet it's scientifically indisputable that a new human life begins
when an embryo first forms at fertilization—6 to 8 days before implantation.
Physicians' textbooks and handbooks
reveal that some types of contraception sometimes work by preventing a living,
developing, embryonic baby from reaching the uterus and successfully
implanting, which results in his or her death.1
Physical Risks for Women
also presents significant health risks for women. Combined oral contraceptives
(COCs), as well as contraceptive patches and the "ring," have long been known
to cause cancer (of the breast, cervix, and liver).2 They
also substantially increase the risk of potentially life-threatening blood
which have resulted in heart attacks, strokes, and hundreds of deaths in
healthy young women.
the Church's teaching, God invites us to a fuller, richer, deeper way of life and
devices (IUDs) present other risks. For example, the following are just some of
the warnings by the Food and Drug Administration (FDA) about one common IUD:
septic shock and death may occur in the event of pregnancy; about half of
pregnancies are ectopic; the device may embed, perforate, or penetrate the
uterine wall, resulting in its migration outside the [uterus], adhesions,
peritonitis, intestinal perforation/obstruction, abscesses, and erosion of
adjacent internal organs.4
From Pill to Poverty
the contraceptive pill, the sexual revolution couldn't have happened. Few women
were willing to risk pregnancy outside of marriage. Economist George Akerlof has
shown how that dynamic abruptly changed with the contraceptive pill, leading to
"the feminization of poverty."5
that the pill would prevent pregnancy, women had sex without the promise of
marriage. Because women controlled the decision to contracept, give birth, or
undergo abortion, however, many men reasoned that they were not responsible for
children conceived outside marriage. Indicating men's denial of responsibility:
"Shotgun marriages" soon plummeted, while out-of-wedlock births nearly tripled.
In less than two decades (1965-1984), abortions among unmarried women grew from
an annual 88,000 to 1,271,000.
the past decade, at least 40 percent of children each year are born to
unmarried mothers who are often left struggling in poverty to raise children
alone. According to Child Trends, "in 2015, 43
percent of children living in single-mother families were poor, compared with
10 percent of children living in married-couple families."6 Poverty
and the absence of a child's biological father in the home are two of the
strongest predictors of poor academic, emotional, and behavioral outcomes in
Contraception Is Unreliable
could abortions and nonmarital births skyrocket if women are contracepting?
With typical use, most contraceptives are far from reliable, especially for
teens, who are twice as likely as adults to become pregnant while using
contraceptive pills, patches, or rings.7 Every year, one million of the 11 million U.S. women
on the pill become pregnant, and 40% of them undergo abortions.8
What Does Our Catholic Faith Offer?
love is generous, sacrificial, life-giving, and forever. As humans made in
God's image, we are called to imitate the eternal giving and receiving of love
that is the Holy Trinity. We can do this in a unique way through marriage—a vowed
communion of a man and a woman who enter a "one flesh" union open to bringing
forth a new human life. "The whole meaning of marriage is present and
signified"9 in each act of marital sex,
so the love-giving and life-giving purposes of sex should not be separated.
the same time, for serious reasons, in exercising responsible parenthood, a
couple may "decide not to have additional children for either a certain or an
indefinite period of time."10 In these cases, "the Church teaches that married people may then take
advantage of the natural cycles immanent in the reproductive system and engage
in marital intercourse only during those times that are infertile."11
to the research of countless doctors and scientists, modern, fertility
awareness-based methods of natural family planning rival and even surpass12 the effectiveness of
contraceptives while posing no risks to mothers or unborn children. In fact, couples
using such methods report better sex, improved communication, and the ability
to identify underlying causes of infertility.13 (To learn more, visit www.foryourmarriage.org/family-planning.)
short, through the Church's teaching, God invites us to a fuller, richer,
deeper way of life and love.
