Contraception & Birth Control: Types, Benefits, Safety & Choosing the Right Method

Contraception & Birth Control: Know Your Options, Take Control of Your Reproductive Health

Contraception is much more than simply preventing pregnancy. It is about having the information and freedom to decide if, when and how often you want to have children. Access to contraception supports the ability to plan pregnancies and spacing between children and can help prevent unintended pregnancies. (World Health Organization)

Your body, your health and your reproductive plans are personal. That is why contraception should be approached as an informed healthcare decision—not something to be considered only after an unplanned situation arises.

What Is Contraception?

Contraception, commonly called birth control, refers to methods used to prevent pregnancy. There are several options, including hormonal methods, intrauterine devices (IUDs), condoms, implants, injectables and permanent methods.

Different methods have different levels of effectiveness, duration, side effects, reversibility and suitability. The right choice depends on an individual's health, preferences, lifestyle and reproductive plans. (World Health Organization)

There is no single contraceptive method that is ideal for everyone.

1. Hormonal Contraceptive Pills

Oral contraceptive pills are among the most commonly used reversible methods of contraception.

Depending on the formulation, pills may contain oestrogen and progestin together or progestin alone. They primarily work by preventing or delaying ovulation and by creating conditions that make fertilisation less likely. (World Health Organization)

For many women, oral contraceptives can be used safely. However, they are not suitable for everyone, and certain health conditions, medications and individual risk factors need to be considered before choosing a particular pill. (World Health Organization)

Pills also require regular use, so consistency is important for effectiveness.

Remember: Oral contraceptive pills do not protect against sexually transmitted infections (STIs). Condoms should be used when STI protection is needed. (World Health Organization)

2. Intrauterine Devices (IUDs)

An IUD is a small device placed inside the uterus by a trained healthcare professional.

There are two broad types:

• Copper IUDs – hormone-free and long-acting

• Hormonal IUDs – release a small amount of levonorgestrel

Both are highly effective, long-acting and reversible. Depending on the specific product, they can provide contraception for several years, and fertility returns after removal. (World Health Organization)

A copper IUD can also be used as emergency contraception when inserted within five days of unprotected intercourse and is the most effective form of emergency contraception. (World Health Organization)

3. Condoms: Simple but Important

Condoms are barrier contraceptives that prevent sperm from reaching the reproductive tract when used correctly.

They have another important advantage: condoms are the only contraceptive method that also provides protection against sexually transmitted infections, including HIV. (World Health Organization)

For contraception to be effective, condoms need to be used correctly and consistently during sexual activity.

If pregnancy prevention and STI protection are both concerns, condoms can also be used alongside another contraceptive method.

4. Implants and Injectable Contraceptives

For women who do not want to remember a pill every day, longer-acting hormonal options may be considered.

Contraceptive implants are small devices placed under the skin of the upper arm and release progestin over an extended period.

Injectable contraceptives contain hormones and provide pregnancy protection for a specified period, depending on the preparation.

These methods can be particularly useful for people who prefer contraception that does not require daily attention. Their suitability should be assessed by a healthcare professional based on individual circumstances. (World Health Organization)

5. Other Contraceptive Options

Depending on individual needs, other options may include:

• Vaginal contraceptive rings

• Contraceptive patches

• Fertility-awareness-based methods

• Permanent contraception such as sterilisation

• Other barrier methods

The choice should take into account factors such as future pregnancy plans, medical history, convenience, effectiveness, possible side effects and personal preference. (CDC)

For those who do not wish to have children in the future, permanent methods may also be discussed with a healthcare provider.

What About Emergency Contraception?

Emergency contraception is useful when unprotected intercourse occurs or when a contraceptive method may have failed—for example, if a condom breaks or contraception was used incorrectly.

Emergency contraceptive pills should be taken as soon as possible, and available emergency methods can generally be used within five days of unprotected intercourse, depending on the method. (World Health Organization)

However, emergency contraception is not intended to replace regular contraception. It is a backup option for situations where regular contraception was not used or may have failed. (CDC)

Repeated reliance on emergency contraception can also be an opportunity to discuss whether a regular contraceptive method would be more convenient and appropriate for you.

Importantly, emergency contraceptive pills do not terminate an established pregnancy and do not cause abortion. (World Health Organization)

Why Planning Ahead Matters

One of the most important aspects of contraception is that you don't have to wait until you are faced with an unplanned pregnancy to think about it.

If you are sexually active and do not currently wish to become pregnant, discussing contraception in advance allows you to understand your options and choose a method that fits your health and lifestyle.

This can help avoid last-minute decisions, anxiety and unnecessary uncertainty.

Contraception is not about fear. It is about preparedness, informed choice and reproductive autonomy.

Does Contraception Affect Future Fertility?

Many modern contraceptive methods are reversible. Fertility generally returns after discontinuation or removal, although the timing can vary depending on the method and individual circumstances. For example, WHO notes that fertility returns quickly after stopping oral contraceptives, while fertility returns immediately after IUD removal. (World Health Organization)

Your doctor can explain what to expect with the particular method you are considering.

How Do You Choose the Right Method?

Instead of choosing a contraceptive simply because a friend or relative is using it,

consider discussing these questions with your gynaecologist:

• Do I want pregnancy soon, later or not at all?

• Do I prefer a daily, monthly or long-acting method?

• Do I have any medical conditions or take regular medications?

• Do I need protection against STIs?

• Am I comfortable with a hormonal method?

• Would I prefer a hormone-free option?

• What possible side effects should I know about?

• How quickly would I like fertility to return after stopping the method?

A healthcare professional can help you weigh these factors and identify an option that is medically appropriate for you. (CDC)

Contraception Is About Choice

Your reproductive health deserves thoughtful planning—not rushed decisions.

Whether you are considering pills, condoms, an IUD, an implant, injections or another method, the most important step is to understand how it works, whether it is appropriate for you and how to use it correctly.

And remember: emergency contraception is a backup—not a substitute for a planned contraceptive strategy.

Be informed. Be prepared. Be proactive about your reproductive health.

Because contraception is not simply about birth control—it is about having the knowledge and support to make informed decisions about your body, your health and your future.

Note: Contraceptive suitability is individual. A method that is appropriate for one person may not be appropriate for another. Speak with a qualified healthcare professional before starting a prescription contraceptive method.
