Things to consider about birth control

By Mayo Clinic staff

Your age, health, emotional maturity, marital status and even your religious convictions come into play when you choose a contraceptive method. Knowing your options is part of the decision process, but an honest assessment of yourself, your partner and your relationship is just as important. Most people have to make some trade-offs. They will, for instance, deal with the mild side effects of some hormonal contraceptives in exchange for superior effectiveness, or forgo the convenience of an IUD for the low cost of a barrier method. Ideally, you and your partner can discuss the options and reach a mutually beneficial decision. For complete information, consider raising the following questions with your health care professional.

What is the method's effectiveness?
The efficacy of any method depends on whether it's used consistently and correctly. Still, the failure rates of some methods are significantly higher than others'. Different people are satisfied with varying levels of effectiveness.

Is it reversible?
The method you choose depends on your life stage and reproductive goals. If you plan to have children at some point in the future, you may want a method that's easily stopped or quickly reversible. If you're certain that you would never desire pregnancy, you may prefer a permanent method.

Is it convenient?
The word "convenient" can be defined in a number of ways, depending on your perspective. For some, convenience means fewer trips to a health care professional. If your schedule is chaotic, you might want to select a method that doesn't require much planning or adhering to a rigid schedule. In that case, a method that's long-acting might fit more easily into your daily routine. For others, the idea of convenience suggests ease of use, no bothersome side effects or no disruption of the sexual experience. It's important to decide what type of birth control is best tailored to your lifestyle.

Can you afford it?
Some methods are inexpensive, while others can be more costly. Consult with your insurance provider if you're unsure about your coverage, and then weigh the expense factor in your choice.

Are health risks involved?
You may want to consider your tolerance for the possible side effects associated with a particular birth control method. Allergic responses to various components of contraceptives could be another determining factor. Some methods, particularly those that contain estrogen, pose the risk of rare but serious side effects. These may occur more often in women with specific characteristics, such as those who smoke and are 35 or older. Consider whether your medical history or lifestyle conflicts with the use of these methods.

Will the birth control method provide protection from STDs?
Unless you're in a mutually monogamous relationship, use condoms to protect yourself from contracting infections such as HIV/AIDS, genital herpes and gonorrhea.

Is the method acceptable to your sexual partner?
Your partner may have birth control preferences that are similar to or different from your own. Discussing all the birth control options with him or her helps you determine which method is acceptable to both of you.

Is the method compatible with your religious beliefs or cultural practices?
Some forms of birth control may be considered a violation of certain religious laws or cultural traditions. Weigh the techniques described here against your particular convictions.

Does the method offer any noncontraceptive benefits?
Besides preventing pregnancy, some contraceptives provide additional benefits such as more predictable, lighter menstrual cycles or a decreased risk of STDs. If these benefits are important to you, they may influence your birth control decision.
