What is Contraception

Contraception, also known as birth control, is a method or device used to prevent pregnancy. It has been a crucial part of human health and reproductive rights for centuries, with evidence of contraceptive use dating back to ancient times.
‍
The concept of contraception is broad and encompasses a variety of methods, each with its mechanisms of action, effectiveness, and potential side effects. The choice of contraception is a personal one, influenced by factors such as health conditions, lifestyle, comfort, and personal beliefs.

Understanding the different types of contraception, how they work, and their potential benefits and drawbacks is essential to making an informed decision about birth control.

History of Contraception

The history of contraception is as old as human civilisation itself. Ancient civilisations used various methods to control fertility, from herbal remedies to physical barriers. In ancient Egypt, for example, women used pessaries made of crocodile dung and honey to block sperm from reaching the uterus.

Over the centuries, contraceptive methods have evolved significantly. The development of the rubber vulcanisation process in the 19th century led to the creation of the first rubber condoms, diaphragms, and cervical caps.

The 20th century saw even more advancements, with the introduction of the birth control pill, intrauterine devices (IUDs), and modern sterilisation methods.

The Birth Control Pill

The birth control pill, often referred to as "the pill," was a revolutionary development in contraception. Introduced in the 1960s, the pill uses hormones to prevent ovulation and thus prevent pregnancy.

It was the first contraceptive method that allowed women to control their fertility without the need for a physical barrier or the cooperation of their partner.

Despite initial controversy, the pill quickly became popular and remains one of the most commonly used contraceptive methods today. It has also paved the way for other hormonal contraceptive methods, such as the patch, the ring, and injectable contraceptives.

Intrauterine Devices (IUDs)

Intrauterine devices (IUDs) are small, T-shaped devices that are inserted into the uterus to prevent pregnancy. There are two main types of IUDs: copper IUDs, which release copper to prevent sperm from reaching the egg, and hormonal IUDs, which release progestin to thicken cervical mucus and prevent ovulation.

IUDs have a long history, with early versions dating back to the 19th century. However, modern IUDs are much safer and more effective. They are a popular choice for long-term contraception, as they can remain in place for up to 10 years.

What Are The 5 Most Common Methods of Contraception?

There are many different methods of contraception available today, each with its advantages and disadvantages. These can be broadly categorised into barrier methods, hormonal methods, intrauterine methods, emergency contraception, and sterilisation.

Choosing the correct type of contraception depends on a variety of factors, including health, lifestyle, personal preferences, and plans for future childbearing. Discussing these factors with a healthcare provider is essential to determine the best option.
‍

• Barrier Methods
  ‍Barrier methods of contraception work by preventing sperm from reaching the egg. They include male and female condoms, diaphragms, cervical caps, and contraceptive sponges. Barrier methods are typically used in combination with spermicide to increase their effectiveness.
  
  Barrier methods have the advantage of being non-hormonal and reversible. They also offer protection against sexually transmitted infections (STIs). However, they must be used correctly and consistently to be effective, and some people may be allergic to the materials used.
  ‍‍
• Hormonal Methods
  Hormonal methods of contraception use hormones to prevent ovulation, thicken cervical mucus, or thin the lining of the uterus to prevent pregnancy. They include the birth control pill, patch, ring, injection, and implant.
  
  Hormonal methods are highly effective when used correctly, and some can also help regulate menstrual cycles and reduce menstrual pain. However, they can have side effects such as weight gain, mood changes, and increased risk of blood clots. They also do not protect against STIs.
  ‍
• Intrauterine Methods
  Intrauterine methods involve the insertion of a device into the uterus to prevent pregnancy. This includes copper IUDs and hormonal IUDs. Intrauterine methods are highly effective and long-lasting, making them a good choice for long-term contraception.
  ‍
  While IUDs can cause side effects such as irregular bleeding and cramping, these often subside after the first few months. IUDs can be removed at any time if the user wishes to become pregnant or experiences adverse effects.
  ‍
• Emergency Contraception
  Emergency contraception is used to prevent pregnancy after unprotected sex or contraceptive failure. It includes the morning-after pill and copper IUDs. Emergency contraception is not intended for regular use but can be a valid backup in case other methods fail.
  
  The morning-after pill is most effective when taken as soon as possible after unprotected sex. Still, the pill can be taken up to 72 hours later. Copper IUDs can be inserted up to 5 days after unprotected sex and can then be left in place for long-term contraception.
  ‍
• Sterilisation
  Sterilisation is a permanent method of contraception that involves surgical procedures to prevent pregnancy. For women, this includes tubal ligation or "having the tubes tied," and for men, vasectomy.
  ‍
  Sterilisation is highly effective and permanent, making it a good choice for those who are confident they do not want more children. However, it is a surgical procedure and carries risks such as infection and complications from anaesthesia. It is also difficult to reverse if the person changes their mind about wanting children in the future.‍

Is Contraception Effective?

The effectiveness of contraception is a critical consideration in family planning, with various methods offering different levels of reliability. Understanding these effectiveness rates helps individuals make informed choices about their contraceptive use.
‍

• Perfect Use vs. Typical Use
  Contraceptive effectiveness is often categorised into "perfect use" and "typical use" rates. Perfect use indicates adherence to the method's instructions without fail. In contrast, typical use reflects the average effectiveness considering common mistakes or inconsistent use.
  ‍‍
• Long-Acting Reversible Contraceptives (LARCs)
  LARCs, such as intrauterine devices (IUDs) and contraceptive implants, are among the most effective forms of birth control, boasting failure rates of less than 1%. Their high efficacy is primarily due to their minimal reliance on user compliance.
  ‍
• Hormonal Methods
  ‍Hormonal contraception, including the oral contraceptive pill, contraceptive injection, and vaginal rings, has a typical use failure rate of around 9%. These methods require consistent daily or periodic use to maintain their effectiveness.
  ‍
• Barrier Methods
  Barrier methods, such as condoms and diaphragms, have typical use failure rates ranging from 12-18%. While less effective at preventing pregnancy compared to LARCs and hormonal methods, condoms are essential for STI protection, highlighting the need for dual protection strategies.

What Are The Side Effects and Risks of Contraception?

While contraception provides an effective means of preventing pregnancy, it's crucial to recognise the potential side effects and risks associated with different contraceptive methods. Making an informed choice involves weighing these against the risks of unintended pregnancy.

• Hormonal Methods: This can lead to nausea, breast tenderness, mood changes, weight gain, and menstrual changes like lighter periods or spotting. They may also increase the risk of blood clots and certain cancers while decreasing the risk of others.
  ‍
• Barrier Methods
  ‍This may cause irritation, allergic reactions, and an increased risk of urinary tract infections. Contraceptive sponges carry a small risk of toxic shock syndrome.
  ‍
• Intrauterine Devices (IUDs):
  Side effects can include cramping, irregular bleeding, and backache. There's also a risk of pelvic inflammatory disease shortly after insertion and a minor risk of uterine perforation during the procedure.
  ‍
• Contraceptive Implants and Injections
  ‍Similar to other hormonal methods, these can cause side effects such as weight gain, mood swings, and changes in menstrual bleeding patterns.
  ‍
• Emergency Contraception
  This may lead to side effects like nausea and vomiting, fatigue, headache, and dizziness, and should not be used as a regular form of birth control due to the high doses of hormones.

Choosing Control

Contraception is an essential aspect of reproductive health and rights, allowing individuals to control their fertility and prevent unintended pregnancies. There are many different types of contraception available, each with its advantages, disadvantages, and effectiveness rates.

Understanding these options and making an informed choice about contraception is a personal decision that can have a significant impact on an individual's health and life.

While contraception is generally safe and effective, it is not without risks and side effects. It's important to discuss these risks with a healthcare provider and to weigh them against the risks of unintended pregnancy.

Access to contraception is also a critical issue, with many people around the world facing barriers to the contraceptive care they need. Efforts to improve access to contraception are ongoing and are a vital part of promoting reproductive health and rights.
