Birth control, also known as contraception, can help prevent
an unwanted pregnancy until you are ready to have a baby. Some forms of birth
control also help protect you from a sexually transmitted disease (STD).
There are many different types of birth control and no
single method is right for everyone. It’s important to consider the pros and
cons of each type of birth control and select the one most suited to your needs
and lifestyle. Think carefully about how easy it is to use and if you are
comfortable using it. You will also want to consider if and when you are
planning to have children.
Other important questions to consider when choosing a birth
control method include:
- Does it contain hormones?
- Does it protect against sexually transmitted
diseases (STDs)?
- Does it require a visit to a doctor or a
prescription from a doctor?
- Does it require preparation right before sex?
- Is it quickly reversible?
- Is it easy to use and will I remember to take it?
- Does it decrease monthly bleeding and cramping
(females)?
- Is it noticeable and do I want my partner to be
aware that I am using it?
- Is it safe?
- Am I allergic to any of its components?
- Does it have side effects and how long will they
last?
- Will it affect my sex drive/sensation during
sex?
- How effective is it?
- How much does it cost?
- Am I willing to pay a lot more now if the method
lasts for a long time?
- How often do I have to take it?
What Types of Birth Control Are Available?
Some methods of birth control work better than others. The
following is a list of the various types of birth control available, sorted by
how effective they are at preventing pregnancies.
Extremely Effective (99-100%)
- abstinence:
Abstinence is complete avoidance of sex.
- intrauterine
device (IUD): This is a small, T-shaped piece of plastic that is put inside
a woman’s uterus by a doctor. There are two kinds. A copper IUD releases a
small amount of copper to prevent sperm from fertilizing an egg. The complete
mechanisms of action of hormonal IUDs are not completely understood. There are
several different types available, all of which release small amounts of
hormones into the uterine cavity. Some of the methods by which this inhibits
conception include thickening of the cervical mucus to prevent sperm penetration,
alteration of the uterine lining to make it inhospitable for a fertilized egg
to implant, and also, in some cases, partially suppressing the release of eggs
from the ovaries (ovulation).
- implants:
An implant is a soft plastic rod that is placed just under the skin of your arm
by a doctor. The rod releases a synthetic progestin hormone over three years.
Its primary mechanism of action is to prevent eggs from being released from the
ovaries.
- sterilization:
This is a permanent method of birth control that involves cutting or blocking
the tubes that carry sperm (in men) or the tubes that carry eggs to the uterus
(in women).
Very Effective (>91%)
- shot:
This is an injection of a progestin hormone which is slowly absorbed by your
body and prevents any eggs from leaving your ovaries. Each injection works for
approximately 12 weeks, so it’s extremely important to receive subsequent
injections on schedule if you wish to maintain contraception.
- patch:
This is asmall sticky patch worn on the skin that sends steady levels of
hormones into your bloodstream.
- vaginal ring:
This is a soft, plastic ring that you put in your vagina, where it releases a
steady dose of sex hormones.
- birth control
pills: This is a set of pills usually taken every single day at the same
time, which contain hormones called estrogen and progesterone. The pill works
by stopping the release of eggs from your ovaries.
Effective (>80%)
- condoms:
This is a thin, disposable wrap placed over the erect penis. If used correctly,
sperm will be trapped inside the condom and will not be able to get inside the
vagina
- cervical barriers
(diaphragm, cap, or shield): A cervical barrier is a small rubber cup that you
fill with spermicidal jelly and place in your vagina, over the cervix, before
sex. This prevents sperm from entering your uterus.
Moderately Effective (>70%)
- spermicides:
These are chemicals that come in the form of jellies, creams, or foams that
kill sperm. They are usually used together with a cervical barrier, such as a
diaphragm.
- sponge:
This is a small foam pad soaked in spermicide and placed in the vagina over the
cervix.
- fertility
tracking: This method involves very carefully tracking changes in your body
so you can know when you are most likely to be fertile and when you are not.
You are not likely to get pregnant if you have sexual intercourse on the days
you are not fertile.
Emergency Contraceptives
Emergency contraceptive pills are used to prevent pregnancy
after you have already had unprotected sex (sex without using a birth control
method). They are sometimes called the “morning after pill.” They may be used
as a backup if your normal birth control method fails or you forget to take it.
Emergency contraceptives can prevent pregnancy for up to
five days after sex. They will not work if you are already pregnant.
Ineffective Forms of Birth Control
These methods are not a reliable form of birth control:
- douching
- urinating after intercourse
- feminine hygiene products
- homemade condoms

How Do I Choose the Method That’s Right for Me?
Figuring out which method to use can be a bit overwhelming. A
method that’s perfect for one woman may not be right for another.
Take a moment to consider all of the important questions and
all of the available options. Then weigh the pros and cons of each option as it
applies to your own lifestyle and future plans. You may even decide to use a
combination of birth control methods for extra protection against pregnancy and
STDs.
You can always talk to a doctor or to a clinic that
specializes in family planning to help you choose a method that is right for
you. The more you know, the more in control you can be of your sexual health as
well as when you may want to have children.
