Birth control is a broad term used to describe various methods and devices that prevent pregnancy. The use of birth control has allowed individuals and couples to take control of their reproductive health and plan their families according to their preferences. Over the years, a variety of birth control methods have been developed to suit different lifestyles, preferences, and health conditions. In this article, we will explore the various types of birth control available today, highlighting their effectiveness, benefits, and potential drawbacks.
1. Hormonal Methods
Hormonal birth control methods use hormones to regulate or stop ovulation, thereby preventing pregnancy. These methods typically involve synthetic versions of the natural hormones estrogen and progesterone, which are responsible for the menstrual cycle. Some hormonal methods may contain only progesterone (progestin) or a combination of estrogen and progestin.
1.1 The Birth Control Pill
The birth control pill, or oral contraceptive, is one of the most widely used hormonal methods of contraception. It contains a combination of estrogen and progestin (combination pill) or just progestin (mini-pill). The pill works by preventing ovulation (the release of an egg from the ovary) and thickening cervical mucus, making it harder for sperm to reach the egg.
Effectiveness: When taken correctly, the pill is about 99% effective. However, its effectiveness can decrease if it is not taken consistently at the same time every day or if certain medications interfere with it.
Benefits:
- Regulates menstrual cycles and reduces heavy bleeding.
- Can help with acne and reduce the risk of ovarian cysts.
- Reduces the risk of certain cancers, including ovarian and endometrial cancer.
Drawbacks:
- Must be taken daily, at the same time each day.
- Can cause side effects such as nausea, headaches, and mood changes.
- Does not protect against sexually transmitted infections (STIs).
1.2 The Birth Control Patch
The birth control patch is a small, sticky patch that releases estrogen and progestin into the bloodstream through the skin. The patch is applied to the skin once a week for three weeks, followed by a week without the patch to allow for a withdrawal bleed (similar to a period).
Effectiveness: The patch is about 99% effective when used correctly.
Benefits:
- Requires less daily maintenance than the pill.
- Regulates menstrual cycles and reduces menstrual cramps.
- Can help reduce acne.
Drawbacks:
- Must be replaced weekly, and it can be visible on the skin.
- May cause skin irritation at the site of application.
- Can have side effects such as headaches, breast tenderness, and mood swings.
1.3 The Birth Control Ring (NuvaRing)
The birth control ring, also known as NuvaRing, is a small, flexible ring that is inserted into the vagina. It releases a combination of estrogen and progestin over a three-week period, and it is removed after three weeks to allow for a withdrawal bleed.
Effectiveness: The NuvaRing is about 99% effective when used correctly.
Benefits:
- Only needs to be replaced once a month.
- Does not require daily attention, unlike the pill.
- Regulates menstrual cycles and can reduce menstrual cramps.
Drawbacks:
- Some people may find the ring uncomfortable or may feel it during intercourse.
- Like other hormonal methods, it can cause side effects such as mood changes, headaches, and nausea.
- Does not protect against STIs.
1.4 The Birth Control Shot (Depo-Provera)
The birth control shot, Depo-Provera, is an injection of progestin that is administered every three months. It works by preventing ovulation and thickening cervical mucus.
Effectiveness: The shot is about 99% effective when used correctly.
Benefits:
- Only requires one shot every three months.
- Very effective in preventing pregnancy.
- Can reduce menstrual bleeding and prevent endometrial cancer.
Drawbacks:
- Requires visits to a healthcare provider every three months.
- May cause side effects such as weight gain, headaches, and mood changes.
- Does not protect against STIs.
1.5 Implants (Nexplanon)
Nexplanon is a small, flexible rod that is implanted under the skin of the upper arm. It releases progestin over a period of up to three years, preventing ovulation and thickening cervical mucus.
Effectiveness: Implants are over 99% effective.
Benefits:
- Long-acting and requires no daily attention.
- Highly effective in preventing pregnancy.
- Can be used by individuals who cannot take estrogen.
Drawbacks:
- Requires a procedure to have it inserted and removed.
- May cause irregular bleeding or spotting.
- Does not protect against STIs.
2. Barrier Methods
Barrier methods of birth control work by physically blocking sperm from reaching the egg. These methods are often used in conjunction with spermicide, which kills sperm.
2.1 Condoms
Condoms are the most commonly used barrier method. They come in both male and female versions. Male condoms are worn over the penis, while female condoms are inserted into the vagina before intercourse. Both types of condoms prevent sperm from entering the cervix.
Effectiveness: Male condoms are about 85% effective with typical use, and female condoms are about 79% effective.
Benefits:
- Easy to use and widely available.
- Provide protection against STIs, including HIV.
- Inexpensive and non-prescription.
Drawbacks:
- Can break or slip off during intercourse if not used correctly.
- Some people may be allergic to latex, though non-latex condoms are available.
- Must be used every time during intercourse.
2.2 Diaphragm
A diaphragm is a flexible, dome-shaped cup made of silicone or rubber that is inserted into the vagina to cover the cervix. It is used with spermicide to prevent sperm from entering the uterus.
Effectiveness: The diaphragm is about 88% effective with typical use.
Benefits:
- Reusable and can last for several years.
- No hormones involved.
- Can be inserted hours before intercourse.
Drawbacks:
- Requires a prescription and fitting by a healthcare provider.
- Must be used with spermicide.
- Can be difficult for some individuals to insert correctly.
2.3 Cervical Cap
The cervical cap is a small, cup-like device that fits over the cervix to block sperm. Like the diaphragm, it is used with spermicide.
Effectiveness: The cervical cap is about 71% to 86% effective, depending on the person’s history of childbirth.
Benefits:
- Can be used as a long-term option if properly cared for.
- Non-hormonal method of contraception.
- Can be inserted hours before intercourse.
Drawbacks:
- Requires a prescription and fitting.
- Must be used with spermicide.
- May cause irritation or discomfort.
2.4 Spermicide
Spermicide is a chemical substance that kills sperm. It is available in several forms, including creams, gels, foams, and suppositories. Spermicide is often used in combination with other barrier methods like condoms, diaphragms, or cervical caps.
Effectiveness: Spermicide alone is about 71% effective.
Benefits:
- Easy to use and widely available.
- Can be used with other barrier methods for added protection.
Drawbacks:
- Can cause irritation or allergic reactions.
- Less effective when used alone.
3. Intrauterine Devices (IUDs)
IUDs are small devices that are inserted into the uterus to prevent pregnancy. There are two types of IUDs: hormonal and non-hormonal (copper).
3.1 Hormonal IUDs
Hormonal IUDs release progestin into the uterus, preventing sperm from reaching the egg and making the uterine lining less receptive to a fertilized egg. They are effective for 3 to 7 years, depending on the brand.
Effectiveness: Hormonal IUDs are more than 99% effective.
Benefits:
- Long-term, reversible contraception.
- Can reduce menstrual bleeding and cramps.
- Requires little maintenance once inserted.
Drawbacks:
- Insertion requires a healthcare provider and can be uncomfortable.
- May cause irregular bleeding or spotting, especially in the first few months.
- Does not protect against STIs.
3.2 Copper IUDs
The copper IUD (ParaGard) does not contain hormones. Instead, copper acts as a spermicide, preventing sperm from fertilizing an egg. Copper IUDs can remain in place for up to 10 years.
Effectiveness: Copper IUDs are more than 99% effective.
Benefits:
- Non-hormonal method of contraception.
- Long-term and reversible.
- Can be used by people who cannot take hormonal contraception.
Drawbacks:
- Can cause heavier menstrual bleeding and more cramping.
- Insertion can be uncomfortable or painful for some individuals.
- Does not protect against STIs.
4. Permanent Methods
For individuals who are certain they do not want to have children in the future, permanent birth control methods may be an option. These methods are irreversible.
4.1 Sterilization (Tubal Ligation)
Sterilization involves surgically blocking or removing the fallopian tubes (for women) or cutting the vas deferens (for men) to prevent sperm from reaching the egg.
Effectiveness: Sterilization is over 99% effective.
Benefits:
- Permanent and highly effective.
- Does not require ongoing maintenance.
Drawbacks:
- Permanent and not reversible.
- Involves surgery and has associated risks.

Effectiveness: A vasectomy is about 99% effective.
Benefits:
- Permanent and highly effective.
- Simple procedure with a short recovery time.
Drawbacks:
- Permanent and not reversible.
- Does not protect against STIs.
5. Natural Methods
Natural methods involve tracking fertility signs to avoid pregnancy. These methods require careful monitoring and discipline.
5.1 Fertility Awareness Methods
Fertility awareness methods involve tracking a woman’s menstrual cycle, cervical mucus, and body temperature to predict fertile days. During the fertile window, couples avoid unprotected sex or use barrier methods.
Effectiveness: These methods are about 76% effective with typical use.
Benefits:
- No hormones or devices involved.
- Can help individuals understand their fertility patterns.
Drawbacks:
- Requires careful tracking and discipline.
- Less effective than other methods.
