What is contraception

What is contraception?

Contraception, often known as birth control, helps people take control of their reproductive health by preventing pregnancy in a safe and reliable way. If you’re thinking about how to prevent pregnancy or take control of your sexual health, you might be wondering what contraception really involves. It’s one of the most common topics patients ask about, and understanding the different contraception methods can make all the difference when choosing what’s right for you.

This guide explains how contraception works, explores the different types of birth control, and answers some of the most frequently asked questions about safety, effectiveness, and accessibility. By the end, you’ll know exactly what your options are and how to make a confident, informed choice.

How does contraception work?

Contraception helps prevent pregnancy by stopping the natural process of conception, where sperm fertilises an egg. Each method of contraception works differently, and the right choice depends on your health, preferences, and lifestyle.

In general, contraception works in three main ways:

1. Preventing ovulation

Some hormonal methods stop your ovaries from releasing eggs. These contain hormones oestrogen and progesterone, or synthetic versions like progestin. They also thicken cervical mucus to block sperm and thin the womb lining, making it harder for a fertilised egg to implant.

Common examples include:

• Combined pill (oral contraceptive pill)
• Progestogen-only pill (mini pill)
• Contraceptive patch
• Vaginal rings
• Contraceptive injection
• Contraceptive implant

These options are reliable, reversible, and widely used. They can also regulate menstrual bleeding and reduce PMS symptoms, with added protection against ovarian and uterine cancers for some users.

2. Blocking sperm

Barrier methods create a physical block that prevents sperm from reaching an egg. This includes:

• Male condoms
• Female condoms
• Diaphragms
• Contraceptive sponge

It is important to remember that condoms are the only method that also protects against sexually transmitted infections (STIs), making them essential for good sexual health.

3. Preventing implantation

Intrauterine devices (IUDs) and intrauterine systems (IUS) are placed inside the womb to stop sperm from fertilising an egg or prevent a fertilised egg from implanting.

There are two main types of contraception that prevent implantation:

• Copper IUD (Copper T-shaped IUD) – This is a non-hormonal device that releases copper salts toxic to sperm.
• Hormonal IUD (intrauterine system) – The hormonal IUD releases progestogen, which thickens cervical mucus and thins the womb lining.

Both options fall under long-acting reversible contraception (LARC), providing effective protection for 3–10 years once fitted.

What types of contraception are there?

There are many different contraception types, each with unique benefits and considerations. Choosing the right one depends on your health, personal preferences, and plans for the future.

Below, we’ve outlined the main options available in the UK and what to expect from each.

Hormonal contraception methods

These options use synthetic versions of the body’s natural hormones to prevent ovulation.

Common hormonal contraceptives include:

• Combined pill – contains oestrogen and progesterone; taken daily.
• Progestogen-only pill (mini pill) – a good choice for those who can’t take oestrogen; also taken daily.
• Contraceptive patch – worn on the skin and replaced weekly.
• Vaginal rings – inserted into the vagina for three weeks, then removed for a one-week break.
• Contraceptive injection – provides 8–13 weeks of protection per dose.
• Contraceptive implant – a small rod placed under the skin, lasting up to 3 years.

These methods can also improve menstrual regularity and reduce symptoms like cramps or heavy bleeding. Some may also provide additional health benefits related to hormonal balance and reproductive health.

Long-acting reversible contraception (LARC)

For people who prefer a low-maintenance option, long-acting reversible contraception can provide years of reliable protection.

Two main options include:

• Intrauterine device (IUD) – a non-hormonal method that uses copper to prevent fertilisation.
• Intrauterine system (IUS) – a hormonal device that thickens cervical mucus and prevents implantation.

Both methods are fitted by a trained healthcare professional and can be removed at any time if you decide to try for a pregnancy.

Barrier methods

Barrier methods are non-hormonal and easy to use, offering immediate protection.

Popular options include:

• Male condoms
• Female condoms
• Diaphragms
• Contraceptive sponge

These methods are widely available and are crucial for protecting against STIs.

Natural and fertility-based methods

Some people prefer to avoid artificial contraception and rely on natural family planning techniques.

Examples include:

• Fertility awareness-based methods – tracking cervical mucus, body temperature, and menstrual cycle length to identify fertile days.
• Lactational amenorrhea method (LAM) – relying on the natural infertility that can occur while exclusively breastfeeding for up to six months after giving birth.

These methods can be effective with careful tracking and support from a health nurse or trained educator but require commitment and consistency.

Emergency contraception

Emergency contraception offers a backup plan after unprotected sex or contraceptive failure.

Two main types are available:

• Emergency contraceptive pills (Emergency pills) – include levonorgestrel or ulipristal acetate; work best within 3–5 days.
• Copper IUD – can be fitted up to 5 days after unprotected sex and continues to provide long-term protection if left in place.

Emergency contraception is safe and effective but should not replace regular contraception methods.

How to choose the right contraception for you

Choosing a form of birth control is a personal decision. The best method depends on your health, age, lifestyle, and family planning goals. A GP, health nurse, or contraception clinic can help assess your options through a confidential consultation.

During your appointment, you can discuss:

• How long you want contraception to last
• Whether you prefer hormonal or non-hormonal methods
• Any medical conditions that could affect your options
• Whether you need protection against sexually transmitted infections

Your clinician will review the medical eligibility criteria based on World Health Organisation (WHO) and UK guidance. This ensures that your chosen method is safe, suitable, and effective.

Why contraceptive choice matters

Access to contraception is about more than pregnancy prevention. It’s a key part of reproductive health, women’s empowerment, and socioeconomic wellbeing.

Effective contraception allows people to:

• Plan pregnancies safely and intentionally
• Reduce the risk of maternal complications
• Space the time between pregnancies for better health outcomes
• Lower rates of teenage pregnancy and unintended pregnancies

At My Local Surgery, we believe that clear, compassionate advice is essential. Everyone deserves the opportunity to make informed decisions about their body and their future.

Can you get pregnant while using contraception?

No method of contraception is 100% effective, but most are highly reliable when used correctly. The chance of pregnancy depends on how the method is used and whether any doses or applications are missed.

Doctors often refer to perfect use and typical use. Perfect use means using the method exactly as instructed. While typical use includes human error, such as forgetting a pill or not replacing a patch on time.

Common reasons for contraceptive failure

• Missing oral contraceptives (pills) or taking them late
• Condom failure caused by incorrect use or breakage
• Discontinuing use of your usual contraceptive without switching to another method
• Forgetting to replace a vaginal ring, patch, or implant on schedule

For most people, hormonal contraceptives, IUDs, and implants offer a success rate of over 99% when used correctly.
