Birth Control Natural Methods

If a woman is sexually active and she is fertile physically able to become pregnant she needs to ask herself,

"Do I want to become pregnant now?"

If her answer is "No," she must use some method of birth control (contraception).

There are a number of different ways to describe birth control.

Terms include contraception, pregnancy prevention, fertility control, and family planning.

But no matter what the process itself is called, sexually active people can choose from a plethora of methods to reduce the possibility of their becoming pregnant. Nevertheless, no method of birth control available today offers perfect protection against sexually transmitted infections (sexually transmitted diseases, or STDs), except abstinence.

In simple terms, all methods of birth control are based on either preventing a man’s sperm from reaching and entering a woman’s egg (fertilization) or preventing the fertilized egg from implanting in the woman’s uterus (her womb) and starting to grow.

The direct responsibility for most of the methods of birth control that are currently available rests with the woman. However, responsibility for contraception should ideally involve the man as well as the woman. The chosen method (or methods) of birth control should thus optimally be a decision and an activity shared by both partners. The input of their health care professionals may sometimes be essential. New methods of birth control are being developed and tested all the time. And what is appropriate for a couple at one point may change with time and circumstances.

Unfortunately, no birth control method, except abstinence, is considered to be 100% effective.

These methods of contraception are considered "natural" because they are non-mechanical and non-hormonal. They are not barrier methods in the sense that they kill the sperm or prevent the sperm from reaching the egg. Additionally, they do not involve the use of hormones. Instead, these methods require that a man and woman not have sexual intercourse during the time when an egg is available to be fertilized by a sperm.

The fertility awareness methods (FAMs) are based upon knowing when a woman ovulates each month. In order to use a FAM, it is necessary to watch for the signs and symptoms that indicate ovulation has occurred or is about to occur.

On the average, the egg is released about 14 plus or minus 2 days before a woman’s next menstrual period. But because the egg survives 3 to 4 days (6 to 24 hours after ovulation) and the sperm can live 48 to 72 hours (up to even 5 days in fertile mucus), the actual time during which a woman may become pregnant is measured not in hours, not in days, but in weeks.

FAMS can be up to 98% effective, but they require a continuous and conscious commitment with considerable self-control. Although these methods were developed to prevent pregnancy, they can equally well be used by a couple to increase fertility and promote conception.

The calendar rhythm method relies upon calculating a woman’s fertile period on the calendar. Based upon her 12 previous menstrual cycles, a woman subtracts l8 days from her shortest menstrual cycle to determine her first fertile day and 11 days from her longest menstrual cycle to determine her last fertile day. She can then calculate the total number of days during which she may ovulate. If a woman’s menstrual cycles are quite irregular from month to month, there will be a greater number of days during which she might become pregnant. The calendar method is only about 80% effective in preventing pregnancy and when used alone is considered outdated.

The basal body temperature (BBT) method is based upon the fact that a woman’s temperature drops 12 to 24 hours before an egg is released from her ovary and then increases again once the egg has been released. Unfortunately, this temperature difference is not very large. It is less than 1 degree F (about a half degree C) in the body at rest.

The basal body temperature method requires that a woman take her temperature every morning before she gets out of bed. An accurate, sensitive thermometer must be used and the daily temperature variations carefully noted. This must be done every month. A computerized monitor for recording and charting fertility is now available on the market, but a woman still must take her own temperature and enter this information into the monitor.

To use the BBT as a birth control method, a woman should refrain from having sexual intercourse from the time her temperature drops until at least 48 to72 hours after her temperature increases again.

The mucus inspection method depends on the presence or absence of a particular type of cervical mucus that a woman produces in response to estrogen. A woman will generate larger amounts of more watery mucus than usual (like raw egg white) just before release of an egg from her ovary. A woman can learn to recognize differences in the quantity and quality of her cervical mucus by examining its appearance on her underwear, pads and toilet tissue.

She may choose to have intercourse between the time of her last menstrual period and the time of increased cervical mucus. During this period, it is recommended that she have sexual intercourse only every other day because the presence of seminal fluid makes it more difficult to determine the nature of her cervical mucus. If the woman does not wish to become pregnant, she should not have sexual intercourse at all for 3 to 4 days after she notices the greatest amount of cervical mucus.

The symptothermal method combines certain aspects of the calendar, the basal body temperature, and the mucus inspection methods. Not only are all these factors taken into consideration, but so are other symptoms such as slight cramping and breast tenderness. Some women experience lower abdominal discomfort (in the area of the ovaries) during release of an egg (ovulation).

A woman can use an ovulation prediction kit to determine when she is most likely to ovulate. This is a special kit that measures the amount of luteinizing hormone (LH). Because LH promotes the maturation of an egg in the ovary, the amount of LH usually increases 20 to 48 hours before ovulation. This increase is called the LH surge, which can then be detected in a woman’s urine 8 to 12 hours later. The ovulation prediction kit is designed to measure the amount of LH in the urine.

There are a number of ovulation prediction kits available on the market which range from simple to complex. In the simplest, the woman urinates onto a test stick and the amount of LH is indicated by a color change. The intensity of the color is proportional to the amount of LH in her urine. A woman begins testing her urine 2 to 3 days before she expects to ovulate based upon the dates of her previous monthly cycles.

More advanced technology assistance is now also on the market. An electronic monitor is available that not only measures the hormones in a urine sample but identifies the 6 most fertile days in a particular woman’s cycle. This electronic monitor costs about $200.00.

The optimum days for fertilization are the two days before ovulation, the day of ovulation, and the day after ovulation. The greatest chance of becoming pregnant is if intercourse occurs within 24 hours after the LH surge. Ovulation prediction kits are used primarily to increase the chance of a woman becoming pregnant, but they can also indicate to the woman that she is about to ovulate and should take appropriate contraceptive precautions.

Withdrawal is also called coitus interruptus. The man withdraws his penis from a woman’s vagina before he ejaculates so that the sperm released from his penis does not enter her vagina.

There are problems with using withdrawal as a contraceptive method. First, a man may release sperm before he has an orgasm. Secondly, a man needs self-control and a precise sense of timing to be able to withdraw his penis from the woman’s vagina before he ejaculates. Because this can be difficult for the man to do successfully, the withdrawal method is only about 75-80% effective in preventing pregnancy.

Lactational infertility is based upon the idea that a woman cannot become pregnant as long as she is breastfeeding her baby. It is true that a woman may not ovulate quite as soon after giving birth as she would if she were not breastfeeding. Women who are breastfeeding usually start ovulating again between 10-12 weeks after delivery.

A nursing mother may start ovulating again and not realize she is fertile, as ovulation can occur prior to the return of her menstrual period. If this happens and the mother has unprotected sexual intercourse, she can become pregnant at the same time she is still breastfeeding her previous baby. If a nursing mother does not wish to become pregnant again, she must again start to use an appropriate method of contraception. (See Depo-Provera, the minipill, barrier methods).

Vaginal douching is the use of a liquid solution to wash out mucus and other types of bodily debris from a woman’s vagina. Many women make regular douching a part of their routine for maintaining vaginal hygiene.

Regardless of whether a woman does it for hygienic reasons, vaginal douching does not work as a contraception method. During intercourse, active sperm can reach a woman’s cervix and even the upper part of her uterus within 5 minutes of ejaculation. Douching after intercourse cannot be done soon enough to have any contraceptive benefits and the douching could force sperm higher up into the uterus. In addition, if a woman douches within a 6-8 hour period after using, for example, a spermicide, she will actually reduce the effectiveness of this contraceptive method.

Some women used to think that standing up and urinating immediately after sexual intercourse might reduce the chances of them becoming pregnant. They hoped that gravity might make it more difficult for sperm to swim "uphill" to the uterus and that the stream of urine running over their vaginal area would wash away sperm, similar to the process of douching. However, just like douching, urination after intercourse does not have any contraceptive value.

Abstinence from sexual activity means not having any sexual intercourse at all. No sexual intercourse with a member of the opposite sex means that there is no chance that a man’s sperm can fertilize a woman’s egg.

A man or a woman can practice abstinence from sexual activity for a specific period of time, or continuously throughout one’s lifetime. Abstinence is essentially 100% effective in preventing pregnancy. Another significant benefit of abstinence is that it markedly reduces the likelihood of contracting a sexually transmitted infection. In this context, abstinence means refraining from all vaginal, anal and oral sexual activity because sexually transmitted infections can be passed from one person to another in any and all of these ways. It should be noted that sexual activity such as mutual masturbation and touching of the other partner’s genitals can, in some instances, transfer sperm during heavy mutual foreplay possibly leading to pregnancy. Oral sex will not cause pregnancy. However, if we are trying to prevent sexually transmitted infection, then any contact can transmit organisms, from kissing on down the line.
