Many of my friends have gotten married over the past year, and I have several more who are preparing for their marriages now. Birth control became a hot topic among friends- "Which one is the most effective?", "How much does it cost?", and "When should I begin taking it?" were all popular questions. Because this is not something that I had ever needed to think about before, I decided to do some research. The below article is one that I feel adequately sums up all of my research and clearly states that birth control is an abortifacient.
Does the Birth Control Pill Cause Abortions?: A Short Condensation
By Randy Alcorn
Please note that this condensation is from an older version of Does the Birth Control Pill Cause Abortions?. Go to the book page to read the complete text of the updated 10th edition, published December 2011.
“The Pill” is the popular term for more than forty different commercially available oral contraceptives. In medicine, they are commonly referred to as BCPs (birth control pills) or OCs (oral contraceptives). They are also called “Combination Pills,” because they contain a combination of estrogen and progestin.
The Pill is used by about fourteen million American women each year. Across the globe it is used by about sixty million. The question of whether it causes abortions has direct bearing on untold millions of Christians, many of them prolife, who use and recommend it.
In 1991, while researching the original edition of my book, ProLife Answers to ProChoice Arguments, I heard someone suggest that birth control pills can cause abortions. This was brand new to me; in all my years as a pastor and a prolifer, I had never heard it before. I was immediately skeptical.
My vested interests were strong in that Nanci and I used the Pill in the early years of our marriage, as did many of our prolife friends. Why not? We believed it simply prevented conception. We never suspected it had any potential for abortion. No one told us this was even a possibility. I confess I never read the fine print of the Pill’s package insert, nor am I sure I would have understood it even if I had.
In fourteen years as a pastor I did considerable premarital counseling, I always warned couples against the IUD because I’d read it could cause early abortions. I typically recommended young couples use the Pill because of its relative ease and effectiveness.
At the time I was researching ProLife Answers, I found only one person who could point me toward any documentation that connected the Pill and abortion. She told me of just one primary source that supported this belief and I found only one other. Still, these two sources were sufficient to compel me to include this warning in the book:
Some forms of contraception, specifically the intrauterine device (IUD), Norplant, and certain low-dose oral contraceptives, often do not prevent conception but prevent implantation of an already fertilized ovum. The result is an early abortion, the killing of an already conceived individual. Tragically, many women are not told this by their physicians, and therefore do not make an informed choice about which contraceptive to use.”[1]
As it turns out, I made a critical error. At the time, I incorrectly believed that “low-dose” birth control pills were the exception, not the rule. I thought most people who took the Pill were in no danger of having abortions. What I’ve found in more recent research is that since 1988 virtually all oral contraceptives used in America are low-dose, that is, they contain much lower levels of estrogen than the earlier birth control pills.
The standard amount of estrogen in the birth control pills of the 1960s and early ‘70s was 150 micrograms.
After the Pill had been on the market fifteen years, many serious negative side effects of estrogen had been clearly proven. These included blurred vision, nausea, cramping, irregular menstrual bleeding, headaches, increased incidence of breast cancer, strokes, and heart attacks, some of which led to fatalities.[2]
In response to these concerns, beginning in the mid-seventies, manufacturers of the Pill steadily decreased the content of estrogen and progestin in their products. The average dosage of estrogen in the Pill declined from 150 micrograms in 1960 to 35 micrograms in 1988. These facts are directly stated in an advertisement by the Association of Reproductive Health Professionals and Ortho Pharmaceutical Corporation in Hippocrates magazine.[3]
Pharmacists for Life confirms: “As of October 1988, the newer lower dosage birth control pills are the only type available in the U.S., by mutual agreement of the Food and Drug Administration and the three major Pill manufacturers.”[4]
What is now considered a “high dose” of estrogen is 50 micrograms, which is in fact a very low dose in comparison to the 150 micrograms once standard for the Pill. The “low-dose” pills of today are mostly 20-35 micrograms. As far as I can tell, there are no birth control pills available today that have more than 50 micrograms of estrogen. An M.D. wrote to inform me that she had researched many pills by name and could confirm my findings. If such pills exist at all, they are certainly rare.
Not only was I wrong in thinking low-dose contraceptives were the exception rather than the rule, I didn’t realize there was considerable documented medical information linking birth control pills and abortion. The evidence was there, I just didn’t probe deeply enough to find it. Still more evidence has surfaced in subsequent years. I have presented this evidence in detail in my 115-page bookDoes the Birth Control Pill Cause Abortions? I will now summarize that research.
The Physician’s Desk Reference (PDR)
The Physician’s Desk Reference is the most frequently used reference book by physicians in America. The PDR, as it’s often called, lists and explains the effects, benefits, and risks of every medical product that can be legally prescribed. The Food and Drug Administration requires that each manufacturer provide accurate information on its products, based on scientific research and laboratory tests.
As you read the following, keep in mind that the term “implantation,” by definition,always involves an already conceived human being. Therefore, any agent which serves to prevent implantation functions as an abortifacient.
This is the PDR’s product information for Ortho-Cept, as listed by Ortho, one of the largest manufacturers of the Pill:
Combination oral contraceptives act by suppression of gonadotropins. Although the primary mechanism of this action is inhibition of ovulation, other alterations include changes in the cervical mucus, which increase the difficulty of sperm entry into the uterus, and changes in the endometrium which reduce the likelihood of implantation.[5]
The FDA-required research information on the birth control pills Ortho-Cyclen and Ortho Tri-Cyclen also state that they cause “changes in...the endometrium (which reduce the likelihood of implantation).”[6]
Notice that these changes in the endometrium, and their reduction in the likelihood of implantation, are not stated by the manufacturer as speculative or theoretical effects, but as actual ones. They consider this such a well-established fact that it requires no statement of qualification.
Similarly, as I document in my book, Syntex and Wyeth, the other two major pill-manufacturers, say essentially the same thing about their oral contraceptives.
The inserts packaged with birth control pills are condensed versions of longer research papers detailing the Pill’s effects, mechanisms, and risks. Near the end, the insert typically says something like the following, which is taken directly from the Desogen pill insert:
If you want more information about birth control pills, ask your doctor, clinic or pharmacist. They have a more technical leaflet called the Professional Labeling, which you may wish to read. The Professional Labeling is also published in a book entitled Physician’s Desk Reference, available in many bookstores and public libraries.
Of the half dozen birth control pill package inserts I’ve read, only one included the information about the Pill’s abortive mechanism. This was a package insert dated July 12, 1994, found in the oral contraceptive Demulen, manufactured by Searle. Yet this abortive mechanism was referred to in all cases in the FDA-required manufacturer’s Professional Labeling, as documented in The Physician’s Desk Reference.
In summary, according to multiple references throughout The Physician’s Desk Reference, which articulate the research findings of all the birth control pill manufacturers, there are not one but three mechanisms of birth control pills:
1. inhibiting ovulation (the primary mechanism),
2. thickening the cervical mucus, thereby making it more difficult for sperm to travel to the egg, and
3. thinning and shriveling the lining of the uterus to the point that it is unable or less able to facilitate the implantation of the newly fertilized egg.
The first two mechanisms are contraceptive. The third is abortive.
When a woman taking the Pill discovers she is pregnant (according to The Physician’s Desk Reference’s efficacy rate tables, this is 3 percent of pill-takerseach year), it means that all three of these mechanisms have failed. The third mechanism sometimes fails in its role as backup, just as the first and second mechanisms sometimes fail. Each and every time the third mechanism succeeds, however, it causes an abortion.
Medical Journals and Textbooks
In an article in the research journal Contraception, Drs. Chowdhury, Joshi and associates state, “The data suggests that though missing of the low-dose combination pills may result in ‘escape’ ovulation in some women, however, the pharmacological effects of pills on the endometrium and cervical mucus may continue to provide them contraceptive protection.”[7]
Note in some citations “contraceptive” is used to refer to an agent which in fact prevents the implantation of an already conceived child. Those who believe each human life begins at conception would see this function not as a contraceptive, but an abortifacient.
Reproductive endocrinologists have demonstrated that Pill-induced changes cause the endometrium to appear “hostile” or “poorly receptive” to implantation.[8] Magnetic Resonance Imaging (MRI) reveals that the endometrial lining of Pill users is consistently thinner than that of nonusers[9]—up to 58 percent thinner.[10] Recent and fairly sophisticated ultrasound studies[11] have all concluded that endometrial thickness is related to the “functional receptivity” of the endometrium. Others have shown that when the lining of the uterus becomes too thin, implantation of the pre-born child (called the blastocyst or pre-embryo at this stage) does not occur.[12]
The minimal endometrial thickness required to maintain a pregnancy ranges from 5 to 13mm,[13] whereas the average endometrial thickness in women on the Pill is only 1.1 mm.[14] These data lend credence to the FDA-approved statement that “changes in the endometrium reduce the likelihood of implantation.”[15]
Dr. Kristine Severyn says:
The third effect of combined oral contraceptives is to alter the endometrium in such a way that implantation of the fertilized egg (new life) is made more difficult, if not impossible. In effect, the endometrium becomes atrophic and unable to support implantation of the fertilized egg.... The alteration of the endometrium, making it hostile to implantation by the fertilized egg, provides a backup abortifacient method to prevent pregnancy.[16]
Researchers have repeatedly and consistently pointed out this abortifacient effect of the Pill. To date, no published studies have refuted these findings.
Dr. Walter Larimore is a Clinical Professor of Family Medicine who has written over 150 medical articles in a wide variety of journals. In two major medical journal articles, he has addressed the issue of the Pill’s capacity to cause early abortions.[17] In 2000 Dr. Larimore and I coauthored a chapter on this subject in The Reproduction Revolution: A Christian Appraisal of Sexuality, Reproductive Technologies and the Family.[18] In the same chapter, four Christian physicians present their belief that the Pill does not result in early abortions. We respectfully suggest that their case is not based solidly on the medical evidence. (In February 2001 Dr. Larimore was brought on the staff of Focus on the Family, as a broadcaster and “an ambassador to the public on medical ethics, procedures and practices.”)
What Does This Mean?
As a woman’s menstrual cycle progresses, her endometrium gradually gets richer and thicker in preparation for the arrival and implantation of any newly conceived child. In a natural cycle, unimpeded by the Pill, the endometrium experiences an increase of blood vessels, which allow a greater blood supply to bring oxygen and nutrients to the child. There is also an increase in the endometrium’s stores of glycogen, a sugar that serves as a food source for the blastocyst (child) as soon as he or she implants.
The Pill keeps the woman’s body from creating the most hospitable environment for a child, resulting instead in an endometrium that is deficient in both food (glycogen) and oxygen. The child may die because he lacks this nutrition and oxygen.
Typically, the new person attempts to implant at six days after conception. If implantation is unsuccessful, the child is flushed out of the womb in a miscarriage. When the miscarriage is the result of an environment created by a foreign device or chemical, it is in fact an abortion. This is true even if the mother does not intend it, and is not aware of it happening.
Despite all the research, including much more presented in my full booklet, there are those who insist that these contentions are incorrect and should not be taken at face value by those concerned about early abortions. In the case of the Pill manufacturers, those who say their FDA-approved assertions are false should, in my opinion, prevail upon the FDA to change their statements, and not simply ask people to disregard them.
Confirming Evidence
When the Pill thins the endometrium, it seems self-evident a zygote attempting to implant has a smaller likelihood of survival. A woman taking the Pill puts any conceived child at greater risk of being aborted than if the Pill were not being taken.
Some argue that this evidence is indirect and theoretical. But we must ask, if this is a theory, how strong and credible is the theory? If the evidence is only indirect, how compelling is that indirect evidence? Once it was only a theory that plant life grows better in rich, fertile soil than in thin, eroded soil. But it was certainly a theory good farmers believed and acted on.
Some physicians have theorized that when ovulation occurs in Pill-takers, the subsequent hormone production “turns on” the endometrium, causing it to become receptive to implantation.[19] However, there is no direct evidence to support this theory, and there is at least some evidence against it. First, after a woman stops taking the Pill, it usually takes several cycles for her menstrual flow to increase to the volume of women who are not on the Pill. This suggests to most objective researchers that the endometrium is slow to recover from its Pill-induced thinning.[20] Second, the one study that has looked at women who have ovulated on the Pill showed that after ovulation the endometrium is not receptive to implantation.[21]
Arguments Against the Pill Causing Abortion
I have received a number of letters from readers, one of them a physician, who say something like this: “My sister got pregnant while taking the Pill. This is proof that you are wrong in saying that the Pill causes abortions—obviously it couldn’t have, since she had her baby!”
Without a doubt, the Pill’s effects on the endometrium do not always make implantation impossible. I have never heard anyone claim that they do. To be an abortifacient does not require that something always cause an abortion, only that it sometimes does.
Whether it’s RU-486, Norplant, Depo-Provera, the morning after pill, the Mini-pill, or the Pill, there is no chemical that always causes an abortion. There are only those that do so never, sometimes, often, and usually.
Children who play on the freeway, climb on the roof, or are left alone by swimming pools don’t always die, but this does not prove these practices are safe and never result in fatalities. We would immediately see this inconsistency of anyone who argued in favor of leaving children alone by swimming pools because they know of cases where this has been done without harm to the children. The point that the Pill doesn’t always prevent implantation is certainly true, but has no bearing on the question of whether it sometimes prevents implantation, which the data clearly suggests.
People also often argue, “The blastocyst is perfectly capable of implanting in various ‘hostile’ sites, e.g., the fallopian tube, the ovary, the peritoneum.”
Their point is that the child sometimes implants in the wrong place. This is undeniably true. But again, the only relevant question is whether the Pill sometimes hinders the child’s ability to implant in the right place.
Imagine a farmer who has two places where he might plant seed. One is rich, brown soil that has been tilled, fertilized, and watered. The other is on hard, thin, dry, and rocky soil. If the farmer wants as much seed as possible to take hold and grow, where will he plant the seed? The answer is obvious--on the fertile ground.
Now, you could say to the farmer that his preference for the rich, tilled, moist soil is based on theoretical assumptions because he has probably never seen a scientific study that proves this soil is more hospitable to seed than the thin, hard, dry soil. Likely, such a study has never been done. In other words, there is no absolute proof.
But the farmer would likely reply, based on years of observation, “I know good soil when I see it. Sure, I’ve seen some plants grow in the hard, thin soil too, but the chances of survival are much less there than in the good soil. Call it theoretical if you want to, but we all know it’s true!”
Some newly conceived children manage to survive temporarily in hostile places. But this in no way changes the obvious fact that many more children will survive in a richer, thicker, more hospitable endometrium than in a thinner, more inhospitable one.
(In other publications and in a much more detailed fashion, we have discussed these and other lines of evidence, with hundreds of citations of many scientific studies, as well as researchers and experts in numerous fields. We encourage interested readers to look more deeply into these studies and arguments. [22])
Despite this evidence, some prolife physicians state that the likelihood of the Pill having an abortifacient effect is “infinitesimally low, or nonexistent.”[23] Though I would very much like to believe this, the scientific evidence does not permit me to do so.
Dr. Walt Larimore has told me that whenever he has presented this evidence to audiences of secular physicians, there has been little or no resistance to it. But when he has presented it to Christian physicians there has been substantial resistance. Since secular physicians do not care whether the Pill prevents implantation, they tend to be objective in interpreting the evidence. After all, they have little or nothing at stake either way. Christian physicians, however, very much do not want to believe the Pill causes early abortions. Therefore, I believe, they tend to resist the evidence. This is certainly understandable. Nonetheless, we should not permit what we want to believe to distract us from what the evidence indicates we should believe.
I have mentioned my own vested interests in the Pill that at first made me resist the evidence suggesting it could cause abortions. Dr. Larimore came to this issue with even greater vested interests in believing the best about the birth control pill, having prescribed it for years. When he researched it intensively over an eighteen-month period, in what he described to me as a “gut wrenching” process that involved sleepless nights, he came to the conclusion that in good conscience he could no longer prescribe hormonal contraceptives, including the Pill, the Minipill, Depo-Provera, and Norplant.
Conclusion
The Pill is used by about fourteen million American women each year and sixty million women internationally. Thus, even an infinitesimally low portion (say one-hundredth of one percent) of 780 million Pill cycles per year globally could represent tens of thousands of unborn children lost to this form of chemical abortion annually. How many young lives have to be jeopardized for prolife believers to question the ethics of using the Pill? This is an issue with profound moral implications for those believing we are called to protect the lives of children.

While the basic argument is stated here, much of the documented evidence has been left out due to space constrictions.

This is the very reason that even when I am married, I will not use any form of chemical birth control. Some may call that extreme, but I am not willing to play "Russian roulette" with my baby, never knowing if I caused my body to abort my child or not. Life or death is not an issue to consider lightly. My goal with this post is simply to get the word out about what the birth control pill actually does, praying that as more women learn about this truth, they will choose to say "no" to the pill.
