Edited By Irshad Anwar | Updated on Jul 02, 2025 07:21 PM IST

What Is Contraception?

Contraception refers to the methods and techniques used in preventing pregnancy. This remains an important factor in family planning, health, and reproductive physiology since it puts control over fertility in people's and their partners' hands.

Types Of Contraceptive Methods

Barrier Methods

Barrier methods are a physical prevention of sperm from getting to the egg. The commonest barrier options include:

The oldest and most commonly used methods include:

Condoms: These guarantee high effectiveness against unintended pregnancy and STIs.
Diaphragms: A barrier is placed over the cervix, used in conjunction with spermicide.

Hormonal Methods

Hormonal contraception works by altering the levels of some of a woman's sex hormones to prevent ovulation. They include:

Oral Contraceptives: These are tablets taken daily that work in controlling the hormone thus preventing ovulation.
Hormonal Implants: the tiny rods are implanted under the skin. The rods slowly release specified hormones.

Intrauterine Devices

The tiny devices inserted into the uterus are either hormonal or copper. They offer protection from getting pregnant for a long time.

Natural Family Planning

The natural methods require one should be able to monitor fertility signs. The methods are:

Basal Body Temperature: The records of the elevation of the basal body temperature will confirm ovulation.
Cervical Mucus Monitoring: Note changes in the cervical mussels to monitor fertile days

Permanent Contraception

Permanent methods are surgical methods for those who do not want children in the future

Tubal Ligation: the female's fallopian tubes are blocked
Vasectomy: the male's vas deferens is cut

Effectiveness Rates

IUD and Implants: More than 99 per cent effective.
Hormonal Methods: 91-99% effective, depending on use
Barrier Methods: 82-98% effective, depending on correct use

Factors To Consider In Choosing Contraception

Health Factors

A patient should consult a healthcare provider about health factors that one is already living with and which would impact the choice of contraception.

Lifestyle Preference.

Among the factors that one considers in choosing contraception would be your lifestyle, how frequently one has sex, and how comfortable one may feel with a given method.

Possible Side Effects And Risks

The public needs to be informed of the possible side effects of a given birth control measure which could be hormonal change, headaches, or even allergic reactions.

Frequently Asked Questions (FAQs)

1. What is the effectiveness rate of the different methods available?

The IUDs and the implants are the most effective, with a failure rate of less than 1%.

2. Can any woman with health problems use contraception?

While most women with health problems can use contraception, it's always best to seek a healthcare provider's advice on the best method for each woman's special needs.

3. How do hormonal contraceptive methods work?

Hormonal contraceptive methods work by suppressing ovulation, thickening of the cervical mucus, and changes in the uterine lining, thereby preventing sperm from reaching and fertilizing an egg.

4. Do methods of contraception have side effects?

Yes; they may include nausea, mood swings, and irregular bleeding with the different methods.

5. Can I change the methods of contraception?

Yes, one can always change the method according to needs and requirements, but it is always good to consult a doctor for proper advice.

6. What is the contraceptive sponge and how effective is it?

The contraceptive sponge is a small, round sponge containing spermicide that's inserted into the vagina before intercourse. It works by blocking the cervix and releasing spermicide. Its effectiveness varies: it's about 88% effective for women who've never given birth and 76% effective for women who have given birth.

7. How effective is the female condom and how does it differ from the male condom?

The female condom is about 79% effective with typical use. It's inserted into the vagina before intercourse and provides a physical barrier to sperm. Unlike male condoms, it can be inserted up to 8 hours before sex and provides more coverage of external genitalia, potentially offering more protection against STIs.

8. What is the diaphragm and how is it used?

A diaphragm is a shallow, dome-shaped cup made of silicone that's inserted into the vagina to cover the cervix. It's used with spermicide and must be left in place for at least 6 hours after intercourse. With typical use, it's about 88% effective in preventing pregnancy.

9. How do contraceptive rings work and how often are they replaced?

Contraceptive rings are flexible rings inserted into the vagina that release hormones to prevent ovulation. They're left in place for three weeks, then removed for one week to allow for menstruation. A new ring is inserted every month. With typical use, they're about 91% effective.

10. How does sterilization differ for men and women?

Male sterilization (vasectomy) involves cutting and sealing the tubes that carry sperm, while female sterilization (tubal ligation) involves cutting, tying, or blocking the fallopian tubes. Both are considered permanent. Vasectomy is generally a simpler, less invasive procedure with a quicker recovery time compared to tubal ligation.

11. Can breastfeeding be used as a form of contraception?

Yes, breastfeeding can be used as a form of contraception, known as the Lactational Amenorrhea Method (LAM). It's effective for up to six months postpartum if the mother is exclusively breastfeeding, hasn't resumed menstruation, and the baby is less than six months old. However, it's not as reliable as other methods.

12. How do fertility awareness-based methods work and what are their limitations?

Fertility awareness-based methods involve tracking various fertility signs (like basal body temperature and cervical mucus) to identify fertile days and avoid intercourse during this time. While they can be effective when used perfectly, they require significant commitment, are vulnerable to cycle irregularities, and don't protect against STIs.

13. Can certain medical conditions affect contraceptive choices?

Yes, certain medical conditions can influence contraceptive choices. For example, women with a history of blood clots, severe migraines with aura, or certain types of cancer may be advised against using estrogen-containing contraceptives. It's important to discuss medical history with a healthcare provider when choosing a contraceptive method.

14. How does a vasectomy work and is it reversible?

A vasectomy is a surgical procedure that cuts and seals the tubes that carry sperm from the testicles. This prevents sperm from mixing with semen, making the man sterile. While vasectomies can sometimes be reversed, they should be considered a permanent form of contraception as reversal success rates vary and decrease over time.

15. What are the potential risks and benefits of using a copper IUD?

Copper IUDs are highly effective (over 99%) and can last up to 10-12 years. They don't contain hormones, making them suitable for women who can't or prefer not to use hormonal methods. Potential risks include heavier periods, especially in the first few months, and a slight increase in the risk of pelvic inflammatory disease, primarily in the first 20 days after insertion.

16. How effective are condoms in preventing pregnancy and STIs?

When used correctly and consistently, male condoms are about 98% effective in preventing pregnancy. They're also highly effective in preventing the transmission of many sexually transmitted infections (STIs), including HIV. However, typical use effectiveness for pregnancy prevention is around 85% due to human error.

17. What is the rhythm method and how reliable is it?

The rhythm method, also known as natural family planning, involves tracking a woman's menstrual cycle to predict fertile days and avoid intercourse during this time. Its effectiveness varies widely depending on how accurately cycles are tracked and how consistently it's used. It's generally less reliable than other methods, with typical use effectiveness around 76-88%.

18. What is the effectiveness of the "pull-out" method?

The "pull-out" method, or withdrawal, involves the male partner withdrawing the penis before ejaculation. It's not very reliable, with a typical use effectiveness of about 78%. This is because pre-ejaculate fluid can contain sperm, and the method requires significant self-control and timing.

19. How do spermicides work and are they effective on their own?

Spermicides are chemicals that kill or immobilize sperm. They work by creating a physical and chemical barrier to sperm. When used alone, spermicides are not very effective (about 72% with typical use). They're most effective when used in combination with other barrier methods like condoms or diaphragms.

20. How do contraceptive patches work and how often do they need to be changed?

Contraceptive patches work similarly to birth control pills, releasing hormones through the skin to prevent ovulation. A new patch is applied weekly for three weeks, followed by a patch-free week. They're about 91% effective with typical use.

21. Can antibiotics reduce the effectiveness of birth control pills?

Most antibiotics do not interfere with birth control pills. However, rifampin, an antibiotic used to treat tuberculosis, can reduce the pill's effectiveness. It's always best to use a backup method of contraception when taking any medication alongside hormonal birth control.

22. What are the potential side effects of hormonal contraceptives?

Common side effects of hormonal contraceptives can include nausea, breast tenderness, headaches, mood changes, and irregular bleeding. Most side effects are mild and often subside after a few months. Serious side effects, though rare, can include blood clots, especially in smokers or those with certain health conditions.

23. What are the advantages and disadvantages of long-acting reversible contraceptives (LARCs)?

LARCs, such as IUDs and implants, offer several advantages: they're highly effective (over 99%), long-lasting, and don't require daily attention. Disadvantages can include initial discomfort during insertion, potential irregular bleeding, and the need for a healthcare provider for insertion and removal.

24. What are the risks associated with using hormonal contraceptives?

While generally safe for most women, hormonal contraceptives can increase the risk of blood clots, especially in smokers and women over 35. They may also slightly increase the risk of certain cancers (like breast cancer) while decreasing the risk of others (like ovarian and endometrial cancer). It's important to discuss individual risk factors with a healthcare provider.

25. How does the contraceptive injection work and how often is it administered?

The contraceptive injection contains progestin, which prevents ovulation and thickens cervical mucus. It's typically administered every 12-13 weeks. It's about 94% effective with typical use but can cause irregular bleeding and may delay return to fertility after stopping.

26. What's the difference between hormonal and non-hormonal contraception?

Hormonal contraception methods use synthetic hormones to prevent pregnancy, such as birth control pills, patches, and injections. Non-hormonal methods don't use hormones and include barrier methods (condoms, diaphragms), copper IUDs, and natural family planning techniques.

27. How does the female birth control pill work?

The female birth control pill typically contains synthetic hormones (estrogen and progestin) that prevent ovulation. It also thickens cervical mucus, making it harder for sperm to reach the egg, and thins the uterine lining, reducing the likelihood of implantation if fertilization occurs.

28. What is an IUD and how does it prevent pregnancy?

An IUD (Intrauterine Device) is a small, T-shaped device inserted into the uterus. There are two types: copper IUDs, which create an environment hostile to sperm, and hormonal IUDs, which release progestin to thicken cervical mucus and thin the uterine lining. Both types are highly effective at preventing pregnancy.

29. What is the contraceptive implant and how long does it last?

The contraceptive implant is a small, flexible rod inserted under the skin of the upper arm. It releases progestin to prevent ovulation and thicken cervical mucus. It's highly effective (over 99%) and can last for up to 3-5 years, depending on the specific type.

30. What is emergency contraception and how does it work?

Emergency contraception, often called the "morning-after pill," is used to prevent pregnancy after unprotected sex. It works primarily by delaying or preventing ovulation. It's not an abortion pill and won't work if a person is already pregnant.

31. What is contraception and why is it important?

Contraception refers to methods used to prevent pregnancy. It's important because it allows individuals and couples to plan their families, space out births, and prevent unintended pregnancies. Contraception also plays a crucial role in promoting reproductive health and reducing maternal and infant mortality rates.

32. What is the role of contraception in managing certain medical conditions?

Hormonal contraceptives can be used to manage conditions like endometriosis, polycystic ovary syndrome (PCOS), and heavy menstrual bleeding. For example, combined oral contraceptives can help regulate menstrual cycles and reduce symptoms in women with PCOS.

33. How do contraceptive needs change throughout a woman's reproductive life?

Contraceptive needs often change with age and life circumstances. Young women might prioritize pregnancy prevention and STI protection. Women in their 20s and 30s might focus on methods compatible with future fertility plans. Perimenopausal women might consider methods that can help manage symptoms while still providing contraception.

34. What are the latest advancements in male contraception?

Research into male contraception includes hormonal methods like gels and injections that suppress sperm production, as well as non-hormonal methods like reversible vas deferens blockage. While progress has been made, most of these methods are still in development and not yet widely available.

35. What are the ethical considerations surrounding contraception?

Ethical considerations include access to contraception as a human right, religious and cultural beliefs about family planning, the environmental impact of hormonal contraceptives, and the balance between population control and individual reproductive choices. These issues can influence personal choices and public health policies.

36. What factors should be considered when choosing a contraceptive method?

Factors to consider include effectiveness, ease of use, potential side effects, health conditions, future fertility plans, protection against STIs, cost, and personal preferences. It's important to discuss these factors with a healthcare provider to find the most suitable method.

37. How do contraceptive methods differ in their ability to prevent STIs?

Barrier methods like male and female condoms provide the best protection against STIs. Other methods like hormonal contraceptives, IUDs, and sterilization are effective at preventing pregnancy but don't protect against STIs. Some methods, like spermicides, may actually increase the risk of STI transmission if used frequently.

38. How does obesity affect contraceptive effectiveness?

Obesity can reduce the effectiveness of some hormonal contraceptives, particularly the contraceptive patch and morning-after pill. This is because excess body fat can affect how these hormones are metabolized. Higher doses or alternative methods may be recommended for individuals with a high BMI.

39. What are the contraceptive options for women over 35?

Women over 35 have many contraceptive options, but some carry increased risks, especially for smokers. Low-dose hormonal methods, progestin-only methods, non-hormonal methods like copper IUDs, and sterilization are often good choices. The best option depends on individual health factors and should be discussed with a healthcare provider.

40. How does the effectiveness of contraceptives differ between perfect use and typical use?

Perfect use refers to using a method correctly and consistently every time, while typical use accounts for human error. For example, condoms are 98% effective with perfect use but about 85% effective with typical use. Understanding this difference is crucial for realistic expectations and choosing an appropriate method.

41. What are the contraceptive options for women who are breastfeeding?

Breastfeeding women have several safe options, including progestin-only methods (mini-pills, implants, injections), non-hormonal methods (condoms, copper IUDs), and the lactational amenorrhea method (LAM) for the first six months postpartum. Combined hormonal methods are generally not recommended in the early postpartum period.

42. How do different contraceptive methods affect menstrual bleeding patterns?

Different methods can have varying effects on menstrual bleeding. Hormonal methods may lead to lighter periods, spotting, or even absence of periods. Copper IUDs might cause heavier periods, especially initially. Understanding these potential changes can help in method selection and managing expectations.

43. How does contraception intersect with issues of gender equality and women's empowerment?

Access to contraception is crucial for women's empowerment, allowing them to control their reproductive lives, pursue education and careers, and make decisions about their bodies. It also promotes gender equality by enabling shared responsibility for family planning between partners.

44. What are the potential interactions between contraceptives and other medications?

Some medications, including certain antibiotics, anti-seizure drugs, and HIV medications, can reduce the effectiveness of hormonal contraceptives. Conversely, hormonal contraceptives can affect the metabolism of other drugs. It's crucial to inform healthcare providers about all medications when discussing contraceptive options.

45. How do contraceptives affect cancer risk?

The relationship between contraceptives and cancer is complex. Hormonal contraceptives slightly increase the risk of breast and cervical cancer but significantly decrease the risk of ovarian and endometrial cancer. The overall cancer risk is neutral to slightly protective for most women using hormonal contraceptives.

46. What are the contraceptive options for individuals with disabilities?

Contraceptive options for individuals with disabilities depend on the specific disability and individual needs. Considerations might include ease of use, potential drug interactions, and the ability to manage side effects. Healthcare providers should work closely with individuals to find the most suitable and accessible method.

47. How do contraceptives affect bone health?

Some hormonal contraceptives, particularly progestin-only injectables like Depo-Provera, can temporarily decrease bone density. However, this effect is generally reversible after discontinuation. Combined hormonal contraceptives may have a slightly protective effect on bone health.

48. What are the environmental impacts of different contraceptive methods?

Hormonal contraceptives can have environmental impacts when excreted into water systems, potentially affecting aquatic life. Barrier methods like condoms contribute to plastic waste. However, the environmental impact of contraception is generally considered less than that of unintended pregnancies and population growth.

49. How do contraceptives affect libido and sexual function?

The effect of contraceptives on libido varies. Some women report decreased libido with hormonal methods, while others experience no change or even increased libido due to reduced pregnancy anxiety. Non-hormonal methods generally don't affect libido, but barrier methods might impact spontaneity.

50. What are the contraceptive options for individuals with chronic health conditions?

Contraceptive options for those with chronic health conditions depend on the specific condition. For example, women with diabetes might avoid high-dose estrogen methods, while those with lupus might use progestin-only or non-hormonal methods. Individualized care and close medical supervision are crucial.

51. How do contraceptives affect fertility after discontinuation?

Most contraceptive methods do not affect long-term fertility. After stopping hormonal methods, ovulation typically resumes within a few months. However, it may take longer (up to a year) for fertility to return after stopping injectable contraceptives. IUDs and barrier methods have no impact on future fertility.

52. What are the psychological effects of different contraceptive methods?

Psychological effects can vary widely. Some women report mood changes or depression with hormonal methods, while others experience improved mood due to reduced pregnancy anxiety. Non-hormonal methods generally don't have direct psychological effects but may impact sexual spontaneity or cause anxiety about effectiveness.

53. How do contraceptives affect the menstrual cycle and related symptoms?

Many hormonal contraceptives can regulate the menstrual cycle, reduce menstrual flow, and alleviate symptoms like cramps and PMS. Some methods, like certain types of pills or hormonal IUDs,
