Birth Control

irth control is a difficult and personal decision. The Bible does not address this issue - probably because in Biblical times there were no good, effective ways to have sex without pregnancy. Because the Bible is silent, there are a wide variety of beliefs about contraception, ranging from those who feel it's sin to use anything (including abstinence when the woman is fertile), to those who feel anything (including abortion) is acceptable. Our goal here is not to debate these theologies, or to provide the final word on contraception - rather we hope to provide factual information that will allow each couple to make an informed, prayerful decision.

No form of contraception is completely effective, but most are fairly good provided they are used correctly and consistently; the vast majority of failures are due to misuse or non-use. Learn all that you can about the method you choose so you can use it properly. More on contraceptive failure, and a chart of failure rates for various methods, here.

Hormonal Methods - Pills, Implants, Shots, Rings and Patches:

Hormonal methods are the most used form of contraceptive today. They are also the most controversial for Christians. Some methods primarily prevent fertilization, while others primarily prevent implantation. The debate about these methods is based on uncertainty about which methods can destroy a fertilized egg, and which do not. If you think life begins when the fertilized egg implants in the womb, the distinction does not matter to you. If you feel it's a sin to do anything that will destroy a fertilized egg, the distinction makes a great deal of difference to you. For detailed investigation of this issue we highly recommend an article by John Guillebaud, Professor of Family Planning and Reproductive Health at University College London, and a dedicated Christian.

Our thinking on how certain hormonal methods do and do not work has changed somewhat over the years (more), in large part because of the influence of several Christian medical professionals with whom we have discussed the issue. What we say here is based on the best science we can find, but there are no absolute answers for some methods.  Ultimately each couple must prayerfully find what is right for them.

All hormonal methods of contraception contain a progestin, a synthetic form of progesterone, and some methods also contain a synthetic estrogen. There are a seven progestins and two synthetic estrogens used, in different combinations and strengths - this means that various methods can have very different side effects. Some side effects are only apparent for the first month of two of using a new method, others are long term. If a woman doesn't have health issues which preclude her using hormonal methods, she should be able to find one that works well for her if she will take time to talk to her health care provider about her cycles and any side effects she experiences.


Other Considerations for hormonal methods: While the current hormonal methods are much safer than the higher dose pills used a couple of decades ago, there are still side effects to consider. All hormonal forms of contraception contain a progestin like chemical, and progestins are well known for lowering sex drive. Complaints of this happening are most common with the long term injections and implants, but it has been noted as sometimes occurring with pills too. Recent reports have suggested that sexual side effects from hormonal contraceptive can last for a year or more after the method is discontinued.

There have been concerns in the past that certain drugs, especially antibiotics, could reduce the effectiveness of hormonal pills. Recent well done studies found no evidence of a problem with most antibiotics3 - the exception being Rifampin, which certainly does increase the chance of ovulation occurring. Still, if it seems wise to use a back up method of contraception while on antibiotics - particular if you feel life begins when sperm and egg join. Several anti-seizure medications (Phenobarbitol, Phenytoin, and Carbamazepine) are well documented to significantly reduce the effectiveness of contraceptive pills, resulting in up to 25 times higher pregnancy rates. Several antifungal medications may also result in more pregnancies - Griseofulvin in particular is a concern, with Fluconazole, Ketoconazole, and Itraconazole being less certain. There is also concern that St. John's Wort may reduce the levels of hormones and result in more more pregnancies. Finally, there is concern that a woman's total body weight may be a factor in how effectively the pill prevents ovulation, so larger women should talk to their doctor and consider avoiding very low does pills.

Another issue is that these methods seem to alter the women's sexual response that comes from pheromones. If she is strongly attracted to a man normally, she may be less attracted while taking hormonal contraceptives.

Pills:

Progestin Only Pills: Progestin Only Pills (POP's) almost certainly allow ovulation at least some of the time. That means possible fertilization, followed by destruction of the fertilized egg, because the progestin inhibits implantation. If you see life as starting at fertilization, POP's are not for you. Click here for a list of progestin only pills. Note - progestin only pills are commonly used as a method for breastfeeding women, and are very effective at suppressing ovulation when combined with lactation.

Combined Oral Contraceptives: There is now good evidence that Combined Oral Contraceptives (COC's), which contain both a progestin and a synthetic estrogen, are so effective at preventing ovulation that fertilization can not occur. It is true that the progestin in the pills could interfere with implantation if an egg was fertilized, but if fertilization never occurs this is irrelevant. There are a couple of caveats to this: firstly the pills must be taken very regularly, not just daily, but at the same time each day, and secondly the week without pills (or with non-hormonal place holder pills) must not be lengthened. (Prof. Guillebaud suggests that one can further improve the ovulation suppression of COC's by reducing the pill free interval to 4 days per cycle - discuss this with your health care provider if interested.)

If a woman can take pills very regularly, COC's should be a safe form of contraception, even for a couple that feels life begins when sperm and egg join. Click here for a list of combination pills.

Other Hormonal Methods:

Many new approaches to hormonal contraception are now available. Some of these are progestin only, but because the delivery system ensures a constant, proper level of the hormone, ovulation may be fully suppressed.

IUDs

Standard IUD: Intrauterine Devices have long been called abortifacients, meaning they allow fertilization but prevent implantation or destroy the egg after it implants. Several studies have proven that the IUD, and particularly those with copper in them, have a powerful spermicidal effect. Further studies have shown that some women with IUDs who did not become pregnant had in their blood a hormone that only occurs after a fertilize egg has implanted. This was less common with copper IUDs, but was seen for both copper and inert IUDs. Clearly in these cases the IUD destroyed the fertilized egg after it implanted. Paragard T380A, which is available worldwide, is currently the most commonly used method of contraception.

Hormonal IUDs:
Barrier Methods:

Male condoms are the most common barrier method - and probably the least enjoyable for most men and many women. If you decide to go this way, it's important to try a number of sizes, since this affects both comfort and effectiveness. If a condom is too short, too wide, or too narrow, try another one. (If you can't find a good fit, try the "TheyFit" brand that comes in 55 sizes.) Condoms need to be put on before there is any contact between the penis and the woman's genitals. After ejaculation the penis must be withdrawn before any loss of erection, and the base of the condom needs to be held in place during withdrawal.

A possible side effect of condoms was recently found - women who use condoms have a higher rate of depression than sexually active women who do not use condoms6. The theory is that semen contains chemicals which act as antidepressants when absorbed by the vagina; women using condoms do not receive this benefit from sex.

Tips for more enjoyable condom use: Female condoms are similar to the male version, except that they are inserted into the vagina. Since the condom does not move with the penis the sensation is more natural and more enjoyable for the man - however, some women find them uncomfortable. Female condoms have about twice the failure rate of male condoms, and are much more expensive. One selling point has been that they are thought to be better at protecting women from STDs.

Diaphragms and Cervical Caps are placed over the cervix along with a spermicide. The spermicide kills sperm, while the diaphragm or cap prevents sperm from entering the cervix. Some people find putting in a diaphragm or cap to be a major interruption, while others see it as a minor issue. These methods are very comfortable for both the man and the woman, as neither should be aware of the product once inserted. These methods have fallen out of favor, in part because they do not prevent STDs, but this is not usually an issue for a Christian man and wife. We know couples who have been very happy with these methods for many years, so don't reject them out of hand.
Diaphragms and standard cervical caps are reusable, prescription items that must be fitted to the woman's body by a doctor. A new fitting is required if the woman gains or loses weight, or has a vaginal delivery. Caps are much more difficult to fit in women who have given birth vaginally, and the failure rate is much higher for such women.


Spermicides can be used by themselves for contraception. There are a number of stand alone spermicides available as suppositories, creams, foams, and even a plastic film. The up side of these methods is that they do not cause a physical separation of the sex organs like condoms. The down sides are timing and possible irritation. Spermicides are only effective for a limited time (typically an hour) and some need to be inside the body for fifteen minutes before intercourse can occur. Some men, and fewer women, are irritated by nonoxynol-9, the active ingredient in all of the stand alone spermicides available in the USA. For women, frequency of use significantly increases the chance of irritation4 - used no more than every other day irritation is rare (3% over placebo). This can range from mild discomfort if they don't wash after sex to strong burning within seconds of contact. Most reactions are actually to one of the non-active ingredients, so changing brands can help in many cases. It should be noted that all stand alone spermicides list the same effectiveness rate, but independent research has shown that higher-dose products (100 mg or more of nonoxynol-9) are more effective, with a quarter fewer failures.5

Sponges: are pieces of foam containing a spermicide that are inserted into the vagina near the cervix. Sponges work both as a block to sperm and by killing sperm. Many women don't care for them, but they a have small loyal following. One advantage of the sponge is that it can be used for multiple sex acts without being replaced. Some men can feel the sponge, or it's removal tab, during sex. The failure rate is high - 9% for women who have not had a child, up to 20% for women who have.
NFP and FAM

NFP and FAM: NFP stands for Natural Family Planning, while FAM stands for Fertility Awareness Method. Both methods involve knowing when the woman is fertile by charting one or more factors such as cycle length, morning body temperature, and condition of cervical mucous.

With NFP the only choices during the fertile time are intercourse with no birth control, and total sexual abstinence. If the signs of fertility are tracked consistently, and the couple does not "fudge" during the fertile time, NFP can be very effective. In fact, couples using NFP correctly have a much lower failure rate than condom users, and about as good as typical pill users. We have theological problems with NFP because it violates the Biblical command to only abstain from sex for the purpose of fasting and prayer (1 Cor 7:5). Note: NFP is the only birth control method approved by the Roman Catholic Church.

FAM uses the same methods as NFP to determine when the woman is fertile, but during the fertile time the couple can have intercourse with a barrier method, or engage in sex that does not include intercourse. Because FAM does not prevent sex, we have no problem with it theologically. Done properly, FAM means a birth control product is only needed for a week to ten days each cycle - this can be nice for both sex and the pocket book. Another advantage of FAM is that both husband and wife are aware of the woman's cycle.
There are devices available to help determine when a woman is fertile and when she is not. The following is a very brief description of three such devices.

Sterilization:

Vasectomy involves cutting the vas deferens, the tubes that transport the sperm out of the testicles. This is done by making a small incision in the scrotum in an outpatient procedure. Failure is very rare, and complications uncommon. Reports in the past tentatively linked vasectomy to some long term health issues, but better studies have since disproved any cause and effect relationship. No change in sex drive is caused by vasectomy, although a very few men seem to have a psychosomatic response that interferes with normal sexual function. Since the testicles provide less than 5% of seminal fluid volume, no difference in ejaculation is seen of felt following the procedure. Occasionally a man has significant problems from a vasectomy, and very rarely these can last for years after the procedure. The type of procedure done, and the skill of the doctor, seem to be factors in how likely a man is to have such problems. Do your homework, and find a doctor with a good deal of experience.
Although vasectomies can sometimes be reversed, this is never assured, and reversals are costly and often painful. A vasectomy should be considered a permanent form of contraception.

Tubal ligation cuts and ties the woman's fallopian tubes so sperm cannot reach egg. A tubal is abdominal surgery, and as such carries far more risk than a vasectomy. For this reason, a tubal seems a poor choice unless the woman is having it done while a doctor is in the neighborhood performing a C-section.
One rare but serious complication of a tubal ligation is an ectopic pregnancy. In an ectopic pregnancy the fertilized egg implants in a fallopian tube rather than in the uterus. This is an extremely dangerous situation that results in death of the mother unless the pregnancy is terminated. The overall rate of ectopic pregnancy for traditional tubal ligations is .7% (7.3 in 1000). The method of performing the procedure has an impact on the chances of an ectopic pregnancy. The age of the woman when the procedure was done was also significant, with women having a tubal under the age of 30 having double the risk of older women7.

Additionally, there have been claims that a tubal ligation can adversely affect a woman's sex drive and in a few instances even her ability to have or enjoy orgasm. Hormonal changes and early menopause are also claimed by some. This is a highly debated topic at present, and it seems impossible at this point to know the truth. We have seen studies which seem to fairly conclusively show some unexplained changes correlated to tubal ligation - for this reason we see a tubal ligation as a risk for a couple intending to continue a mutually enjoyable sex life.

Birth control is a difficult issue for Christians, and we pray the information given here will help couples make an informed choice.

It's probably impossible to write an article like this without one's opinions tainting what is said, so it seems only fair to clarify what we believe personally. We are convinced that God has a will for each couple with regard to number and spacing of children, and we need to pray to know that will. We believe it is acceptable to use some forms of contraception to fulfill this will. Because we believe life starts at the moment the sperm and egg join, we could not personally use methods that destroy a fertilized egg. Neither do we feel it's right to use a form of birth control which involves abstinence.
