Contraceptive Choices
You've made the important decision to practice birth
control and now you're faced with another: which method? As you'll see,
there are several available, and with good reason; because no two people
are alike, no one method is right for everyone. This guide is designed to
help you make an informed decision about reversible birth control methods.
In it, you'll find an introduction to the many contraceptive options
available to you. Then, with your doctor's or health care provider's
help, you'll be able to decide on one that works best with your lifestyle
and your needs.
Whichever birth control method you choose, keep in
mind that even the most effective and appropriate method can fail if
you're not able to make a consistent, ongoing commitment to using it.
Whether your regimen is something you'll take daily, like a pill, or use
only as needed, like a diaphragm, its success depends on you. Make sure
you fully understand how and when to use the method you and your doctor or
health care provider have chosen. Remember, this guide is only an
introduction; your doctor or health care provider can best answer any
questions you might have. Be sure to keep in touch with her or him for
regular checkups, your contraceptive choice.
Conception: What Happens?
A Look Inside
The uterus, or womb, is a muscular chamber about the size and shape of
a pear. This is where a fertilized egg can implant and develop into a
baby. The cervix is the opening of the uterus through which sperm enter
to fertilize an egg and through which a baby usually leaves the uterus.
The vagina is the passageway between the uterus and the outside of the
body. This is the canal through which a baby is delivered and where the
penis is inserted during sexual intercourse.
The ovaries are two walnut‑sized structures located
on either side of the uterus. Each holds thousands of tiny egg
follicles‑clusters of cells that contain an immature egg at their centers.
The ovaries also produce hormones needed for reproduction.
The fallopian tubes connect the ovaries and the
uterus. About 4 inches long, they each begin at an opening on either side
of the uterus and end in a funnel that surrounds (but doesn't attach to)
each ovary.
Ovulation & Conception
About once a month, the lining of the uterus begins to thicken in
preparation to receive and nourish a fertilized egg. At the same time,
several egg follicles begin to mature, but usually only one develops
fully, with a mature egg inside. It moves to the surface of the ovary, and
the follicle comes apart, releasing the egg into the fallopian tube. This
process is called ovulation.
Over the next few days, the sides of the fallopian
tube squeeze periodically to push the egg down to the uterus. If the egg
is not fertilized during this critical time, it will disintegrate in the
uterus. And, since the thickened uterine lining is no longer needed, it
will be shed over a period of 2 to 8 days. This discharge, containing
blood, cells, and other secretions, is menstrual flow, or "a period."
The time interval from one period to the next is the
menstrual cycle. Just after ovulation, while the egg is on its way toward
the uterus, it may be fertilized by a man's sperm, which is deposited
during sexual intercourse. Several million sperm can be contained in the
semen released from the penis; only one such sperm must reach the
egg‑usually while it is still in the fallopian tube‑for pregnancy to
occur. This process is called conception. Once fertilized, the egg takes
several days to travel down the fallopian tube to the uterus, where it
implants in the uterine lining and begins to develop into a baby.
When Am I Most Likely to
Conceive?
Every woman's cycle is different; it is possible to
conceive on almost any day in your cycle. However, your greatest chance of
conception occurs just before, during, and just after ovulation. For women
with regular, 28‑day menstrual cycles, ovulation is likely to occur 14
days before the next menstrual period is expected.
Because sperm can survive in the fallopian tube for 2
or 3 days, the most fertile period begins 2 to 3 days before ovulation.
Although the egg may be in the fallopian tube for 2 or 3 days, the fertile
period usually ends by the time the unfertilized egg reaches the uterus.
It's important to remember, however, that your fertile period may vary
from the norm and may even change from cycle to cycle. If you're
interested in determining your own cycle, consult with your doctor or
health care provider.
BIRTH CONTROL OPTIONS
Oral Contraceptives (Birth Control Pills)
How Do Oral Contraceptives
Work?
Oral contraceptives suppress the hormones that cause
ovulation. The process of ovulation is directed by hormones, chemicals
made by the body. Some hormones signal for egg follicles to mature in the
ovary, for example; others trigger the thickening of the uterine wall.
Oral contraceptives consist of man‑made versions of two of these hormones;
taken daily, they block the usual hormone "messages" that direct
ovulation. No eggs are produced, so conception is prevented.
Other effects of oral contraceptives help prevent
sperm from reaching the egg and reduce the chance of the egg implanting in
the uterus. Oral contraceptives are one of the most effective forms of
reversible birth control currently available.
There are several types of oral contraceptives, with
different levels and types of hormones.
Most pills contain a uniform combination of two
hormones, progestogen and estrogen; they are called "combination oral
contraceptives," or, simply, "the pill." Another type, "mini‑pills,"
contain only progestogen. Also available are "phasic contraceptives," or "multiphasics,"
which contain the two hormones progestogen and estrogen in varying doses.
Every woman's cycle is different, and so are her needs in an oral
contraceptive. Your doctor or health care provider can determine a type
that's right for you.
What Do I Have to Do?
Combination birth control pills are probably the
easiest birth control method to use--you only need to take them once
daily, at the same time each day. Then, for 7 days each month, you stop
taking the pills (or you take inactive, “placebo" pills). During this
"time off," you will usually experience bleeding similar to a normal
menstrual period. When taking the active pills, you must take one every
day in order to be protected.
Are Oral Contraceptives
Right for Me?
Only your doctor or health care provider can
determine if you’re a suitable candidate for birth control pills. When
used correctly, the pill is 99% effective, making it the most popular
method. It is considered safe for most healthy nonsmokers, even past age
35. While the pill may reduce the risk of acute Pelvic Inflammatory
Disease (PID), it offers no protection against other sexually transmitted
diseases (STDs).
Serious as well as minor side effects have been
reported in women using oral contraceptives. You should discuss these
risks with your doctor or health care provider. Birth control pills are
one of the most effective reversible forms of contraception.
Injection
How Do Injections Work?
Contraceptive injections are given to you by your
doctor as a hormone "shot" into the muscle of your upper arm. Once
administered, a low dose of this hormone, progestin is released into your
system over a period of 3 months. This progestin, similar to the progestin
in birth control pills, suppresses ovulation and provides effective
contraception for 3 months.
What Do I Have To Do?
Once your doctor gives you an injection there's
nothing you have to do for 3 months. However, scheduling regular visits
with your doctor or health care provider for an injection every 3 months
is important to make sure you are protected.
Is an Injection Right for
Me?
It's up to you and your doctor or health care
provider to decide if the injection method is right for you. It may be
appropriate if you want long‑term contraception without having to take
birth control daily or use other contraceptive devices such as diaphragms,
condoms, cervical caps, spermicides, or the sponge. However, the injection
requires an office visit every 3 months, and immediate discontinuation is
not possible. Menstrual irregularities, such as spotting and bleeding
between periods, are common.
The Patch
How Does the Patch Work?
The patch is thin, beige, plastic patch that sticks to your
skin. The patch is usually placed on the skin of the buttocks, stomach,
upper arm, or torso the same day each week for three weeks in a row. No
patch is used in the fourth week. The patch much like the pill releases
synthetic estrogen and progestin into the blood stream.
What Do I Have to Do?
The patch is easy to use--you reapply the patch once a week. Then, for 7 days each month, do not reapply the patch. This is called "time off" where you may experience bleeding similar to a normal menstrual period.
Is the Patch Right for
Me?
It's up to you and your doctor or health care provider to decide if the patch is right for you. It may be appropriate if you have trouble remembering to take a pill once a day. The patch is 99% effective with proper use. The patch offers no protection against other sexually transmitted diseases (STDs).
The Nuva Ring
How Does the Nuva Ring Work?
The Nuva Ring is a soft flexible ring that is approximately two inches in diameter and is worn in the vagina for three weeks. The ring contains a combination of estrogen and progestin hormones similar to the hormones used in the pill. The hormones contained within the ring are absorbed continuously, directly into the blood stream through the vaginal walls.
What Do I Have to Do?
The ring is convenient and easy to use. You insert one new ring into
the vagina and keep it in place for three weeks in a row. Then remove it
for one week in order to menstruate, much like the patch.
Is the Nuva Ring Right for Me?
Only your doctor or health care provider can determine if
you’re a suitable candidate for the Ring. According to studies provided
to the Food and Drug Administration (FDA) during the approval process,
effectiveness ratings are listed at 99% when used according to labeled instructions. This is comparable to the patch and better than the Pill’s effectiveness ratings.
Diaphragm
How Does a Diaphragm Work?
The diaphragm must be fitted by your doctor or health
care provider and always used with contraceptive jelly or cream. It forms
a barrier to the uterus, preventing sperm from entering and fertilizing an
egg. A diaphragm is a soft rubber, latex, or silicon cup that is filled
with contraceptive jelly or cream and inserted into the vagina to cover
the opening at the bottom of the uterus, called the cervix.
The diaphragm works in two ways: it provides a
physical barrier to semen, and it holds the contraceptive jelly or cream,
which kills sperm before they can enter the uterus and fertilize an egg.
When used properly--which means always using jelly or cream--the diaphragm
is highly effective; if your partner uses a condom at the same time, its
effectiveness is greatly enhanced.
What Do I Have to Do?
Spermicide is applied to the diaphragm, which is
inserted into the vagina so that it covers the cervix and is held securely
in place behind the pubic bone and rear wall of the vagina, If you have
intercourse again, you need to add more contraceptive jelly or cream each
time. This is inserted with a special applicator while the diaphragm is
still in place.
The diaphragm should remain in place for 6 hours
after intercourse and should be removed as soon as possible thereafter.
Each time you use your diaphragm, you should check it to make sure there
are no holes or tears in it. It should be replaced every 2 years or
sooner. Also, have your diaphragm size checked by your doctor or health
care provider once a year or after you’ve had a pregnancy, or gained or
lost more than 10 pounds.
Is the Diaphragm Right for
Me?
Your doctor or health care provider can tell you if
the diaphragm is a suitable birth control method for you. It requires
substantial user involvement: applying spermicide, inserting, cleaning,
proper storage. Use of a diaphragm may increase risk of urinary tract
infections. Toxic shock syndrome (TSS) has been reported in some women
using diaphragms. Consider it if you prefer a birth control method you
only have to use when you need it and if you’re committed to following the
procedures for using it properly. For many women, it’s an easy habit to
get used to.
Condoms
How Do Condoms Work?
A condom is a thin shield that is fitted directly on
a man’s penis. It traps the semen expelled from the penis during
intercourse, preventing sperm from fertilizing an egg. There are many
types of condoms available; most are made of latex rubber, but some are
made from animal tissue like lambskin (also called “natural” condoms).
They may be lubricated or ribbed or treated with a spermicide.
Latex condoms, especially those that are treated with
a spermicide, help prevent both partners from giving each other sexually
transmitted diseases (STDs). Condoms can be bought without a
prescription. A condom is worn on the penis. It collects semen and
prevents sperm from entering the uterus. Although condoms are quite
effective, they may tear or slip off during intercourse.
What Do I Have to Do?
A man must put on a condom when his penis is erect
but before intercourse. Afterward, he should withdraw immediately to
prevent leakage. It’s a good idea for you to use a backup form of birth
control in case of leakage or breakage. Possible choices: spermicide
suppositories, jelly, cream, or foam; a diaphragm; or the contraceptive
sponge.
Are Condoms Right for Me?
Virtually any male can wear a condom; it’s
convenient, inexpensive, easy to obtain, and highly portable. The added
protection against sexually transmitted diseases (STDs) makes it a good
choice if you have more than one sexual partner. However, condoms can
reduce sexual spontaneity and sensation, and may break or leak, posing a
heightened risk of pregnancy.
Female Condoms
How Do Female Condoms Work?
The female condom is a lubricated plastic sheath with
rings on each end, The ring on one end is open and remains outside the
vagina, covering part of the labia. The ring on the other end is closed
with the plastic and looks like a diaphragm. It's placed in the vagina so
that it covers the cervix, preventing sperm from entering the uterus. The
sheath between the two rings forms a pouch to line the entire vaginal
area. Like the use of the male latex condom, female condoms are available
without a prescription
What Do I Have to Do?
The female condom can be inserted up to 8 hours
before intercourse. Follow the package directions for correct insertion.
It's important that the closed ring section hugs the cervix. Additional
spermicide may be used before and after the condom is in place. Since this
condom is made from polyurethane rather than latex, oil‑based spermicides
and lubricants will not damage it. The female condom should be removed
immediately after intercourse, before you stand up. As with any condom, it
is a one‑use‑only item, and should be properly disposed of after use.
Are Female Condoms Right for
Me?
Like the male condom, the female condom offers
protection against STDs as well as contraception. Additionally, the woman
controls its use (unlike use of a male condom). However, the female condom
is more cumbersome to use, more visible, and less comfortable than a male
condom.
Intrauterine Device (IUD)
How Does the IUD Work?
The IUD is a small plastic device, containing copper
or the hormone progesterone, that is placed by a doctor or health care
professional inside the uterus for an extended length of time. In fact,
the copper IUD may be used for up to 8 years. It is a highly effective
contraceptive and is thought to work by preventing sperm from reaching or
fertilizing the egg. The modern IUD is one of the most effective forms of
birth control available.
What Do I Have to Do?
Your doctor or health care provider must insert an
IUD; once it is in place, you should check the placement regularly, at
least after each menstrual period. Schedule regular follow‑up visits with
your doctor or health care provider, and have your IUD replaced as he or
she directs.
Is an IUD Right for Me?
Your doctor or health care provider will help you
determine if an IUD is an appropriate birth control method for you. It is
appropriate for women who have had at least one child and are in a
mutually monogamous relationship, since it does not protect against
sexually transmitted diseases. Consider the IUD if you want sexual
spontaneity, high degree of effectiveness, and a long‑term contraceptive.
Emergency Contraception
How Does Emergency Contraception Work?
If you have had sex without birth control or your birth control method has failed within the past 3 days, you can use Plan B to reduce your risk of pregnancy. If it has been longer than 3 days consult your physician. Plan B contains large doses of levonorgestrel that can be found in a single birth control pill.
What Do I Have to Do?
Plan B is an emergency contraception or back up method of birth control that can only be ordered and taken by women. A prescription from a doctor is NOT necessary to order this product and you can dispense Plan B at most big pharmacies.
Is Emergency Contraception Right for Me?
Plan be should never be used as a primary source of birth control, however it is available for a back up plan or last resort. Plan B will decrease your chances of getting pregnant up to 89%. The advantage to Plan B is that
it is easily accessible to women years 18 or older without a prescription and it is more effective the sooner you take it.
Natural Family Planning
How Does Natural Family
Planning Work?
Natural family planning is based on the fact that
fertilization is most likely to occur just before, during, and just after
ovulation. By carefully monitoring yourself daily, you may be able to
determine when you are ovulating and thus predict when you are most
fertile. At those times you could practice birth control just by avoiding
intercourse. While more effective than no birth control at all, natural
family planning has a high failure‑rate because even the most regular
cycles can vary from month to month. It is perhaps the least effective
birth control method.
What Do I Have to Do?
To monitor your ovulation schedule, you need to use a
calendar daily for at least 3 months. You can note ovulation using two
different methods: (1) basal body temperature (BBT) and (2) cervical mucus
charting.
The BBT method is based on the fact that just before
ovulation, your body temperature drops and then rises steadily for a few
days. If you take your temperature daily for several months and plot it on
a chart, you will probably be able to see a pattern. This pattern helps
you predict your most fertile days and abstain from intercourse at those
times.
Cervical mucus charting requires that you take a
sample of any mucus (discharge) from your vagina daily. Close to or during
ovulation, the mucus should become clear, elastic, and slippery. If you
chart your cervical mucus findings over several months, you may see a
pattern that will allow you to predict your next fertile period.
Is Natural Family Planning
Right for Me?
Natural family planning is best used only by women
with very regular, predictable cycles. Ask your doctor or health care
provider if you are an appropriate candidate. Consider natural family
planning if you choose not to use a birth control device and if you are
willing to stick to a time‑consuming schedule of daily readings for
several months. Overall, this is the least effective method.
How Do the Methods Compare?
Use this chart to compare the failure rates of the
methods we've discussed.
Each is listed with its lowest expected failure
rate‑that is, the percentage of pregnancies with the method if it is used
properly‑and with its typical failure rate, or the percentage of
pregnancies reported by average users.
