How FDA-approved contraceptive methods work

  1. This needs a correction. All hormonal methods also may prevent implantation.

    1. I note that my comment made it through moderation, but no correction was made to the original post/article. Why?

      1. I see this was posted later:

        That covered the issue a bit better. I also subsequently noticed that both stories are reprints of copyrighted articles from RNS (Religious News Service). However, they should not have been shared without comment.

      2. LCMS Church Information Center says:

        This is an RNS story, and because it came to us over the wire, we hold no rights to it and therefore cannot correct it.

        1. Right. I see now that this LCMS “Periscope” blog is simply being used to repost articles from other Internet sources that may be of interest to readers. Unfortunately, if one does not see the fine print they look as if they are news reports from the LCMS. I recommend that each article be introduced with so and so of such and such news agency reports…

  2. And by “prevent implantation,” we mean “abortion.”

    1. Right! That should definitely be clarified. Most people do not know what implantation is.

  3. I thought perhaps I would join these gentlemen in suggesting the correction by providing some evidence from the Physicians Desk Reference (PDR)

    The following is from the summary of “Brevicon/Norinyl” one of the more popular “Non-abortifacient” pills.


    Estrogen/progestogen oral contraceptive; suppresses gonadotropins. Primarily inhibits ovulation. Also causes changes in cervical mucus (increases difficulty of sperm entry into uterus) and endometrium (reduces likelihood of implantation).”

    This one is from the summary of “Desogen” another popular “Non-abortifacient” pill.


    Estrogen/progestogen oral contraceptive; acts by suppressing gonadotropins, primarily inhibiting ovulation, and causing other alterations, including changes in cervical mucus (increases difficulty of sperm entry into uterus) and endometrium (reduces likelihood of implantation).”

    This is information from Mirena, an Intrauterine Device “IUD”

    “Progestogen; has not been conclusively demonstrated. Thickens cervical mucus (preventing passage of sperm into uterus), inhibits sperm capacitation or survival, and alters endometrium.”

    The phrase to watch is “alters/changes endometrium.” In the case of the pills it is parenthetically explained “reduces likelihood of implantation” which as they have pointed out is equivalent to abortion because implantation can happen as late as 9 days after fertilization.

    All of this was in a quick search of, a free resource publish by the FDA. More information as well as apologetics can be found in a very inexpensive book call “Does the birth control pill cause abortions” by renowned researcher Randy Alcorn.

    I appreciate your care in considering this important issue and pray that you see the error in distinguishing between “abortifacient” and “non-abortifacient” methods.

  4. Robert Franck says:

    This article might relay information from an FDA website, but particularly regarding the “hormonal methods,” an important aspect of the way it might work is lacking. I suggest people read the LCMS Sanctity of Human Life Committee document titled “Guidance on Contraceptive Methods” for more detailed and well-researched information, particularly about the way hormonal methods also might “prevent implantation” or cause early abortions. You can find that information at

  5. One thing that must be kept in mind is that all “contraceptives”, no matter what the mechanism of action, can and do “fail” at a certain rate. That means that all “contraceptives” will allow the sperm and egg to meet under certain conditions, and at the moment that sperm and egg meet, there is a new human life. This moment is called “fertilization”. Sometimes this “failure rate” is 1 in 20, sometimes this failure rate is 1 in 1000 or less. but ALL contraceptives “fail” at a certain rate. These “failure rates” are published and available. Thus ALL methods have the possibility of embryos being created during the use of that method.

    The question then becomes, what does that “contraceptive” do to an embryo who has just been created? Clearly some contraceptives work by more than just preventing sperm and egg from meeting, for example, emergency contraception with the drug Ella clearly also kills the embryo, and in fact, killing an embryo may actually be the major mechanism of action of Ella depending on when in the woman’s cycle Ella was taken.

    With Plan B, there is some scientific evidence that taken at certain times in the cycle, egg release will not be prevented, and yet Plan B is still “effective”. Clearly whenever egg release is not prevented there is the possibility of fertilization.

    One word of caution and clarification in this discussion. The term “abortion” is technically applied to the killing of embryonic and fetal human beings AFTER the embryo has implanted in the lining of the mother’s uterus. So, by this sophistry, a drug that kills embryos BEFORE implantation could not technically be labelled an “abortifacient”. For this reason, it is better to use unequivocal terms like “Kills embryonic human beings”, or “kills human beings after fertilization”. There is no equivocation about the term “fertilization”.
