The Safest Contraceptive Methods Available Today

Overview of Contraceptive Methods

Choosing the right contraceptive method is a personal decision that depends on age, health, number of children, and future reproductive plans. With over 30 years of experience in obstetrics, gynecology, and family planning, BSCKI. Trần Thị Thúy Lâm shares this detailed comparison to help women make the best choice.

There are many contraceptive methods available today with varying levels of effectiveness, usage, and side effects. No single method is perfect for everyone — the best method is one that suits your health condition, lifestyle, and personal needs.

Comparison Summary Table

Typical-use effectiveness (including incorrect usage)

Important note: Theoretical and typical-use effectiveness differ greatly. For example, combined pills are 99% effective with perfect use but only 91% in practice because many women miss pills. This is why LARC methods (not dependent on user compliance) are always preferentially recommended.

Long-Acting Reversible Contraception (LARC) — Most Effective

LARC (Long-Acting Reversible Contraception) is the most effective group of contraceptive methods available today because they do not depend on daily use. Once placed/inserted, you don’t need to remember anything.

Contraceptive Implant

Contraceptive implants are the method with the highest effectiveness among all available contraceptives:

• Mechanism: A small rod (matchstick-sized) containing etonogestrel hormone, inserted under the skin of the inner upper arm
• Duration: 3-5 years (depending on Implanon or Nexplanon type)
• Effectiveness: 99.95% — nearly absolute
• How it works: Suppresses ovulation, thickens cervical mucus, thins uterine lining
• Advantages: No need to remember pills, safe while breastfeeding, can be removed at any time
• Disadvantages: May cause menstrual irregularities (abnormal bleeding, missed periods), headaches, slight weight gain
• Cost: 500,000 - 2,000,000 VND (one-time, effective for 3-5 years)
• Best for: Women wanting long-term contraception, breastfeeding mothers, those who cannot use estrogen

Implant procedure: Performed in 5-10 minutes at the clinic with local anesthesia, virtually painless. Mild bruising may occur for a few days. Can be removed at any time and fertility returns within 1-2 weeks.

IUD (Intrauterine Device)

IUDs come in two main types:

Copper IUD:

• Duration: 5-10 years
• Hormone-free — suitable for women who prefer not to use hormones
• Mechanism: Copper ions create an environment unfavorable to sperm and fertilized eggs
• Disadvantage: May increase menstrual flow and period cramps
• Effectiveness: 99.2%

Hormonal IUD (Mirena/Levosert):

• Duration: 5-7 years
• Releases low-dose levonorgestrel hormone locally
• Additional benefit: Significantly reduces menstrual flow and period pain
• Best for: Women with heavy periods, severe cramps, endometriosis
• Effectiveness: 99.8%

IUD insertion procedure: Performed in 10-15 minutes at the clinic. Best inserted during the first 7 days of the menstrual cycle or immediately after delivery/miscarriage. Mild cramping during insertion resolves within a few hours.

Who should not use an IUD?

• Women with active pelvic infection
• Severe uterine abnormalities
• Uterine fibroids distorting the uterine cavity
• Currently pregnant

Daily Methods — Birth Control Pills

Combined Oral Contraceptives (COC)

Combined pills contain estrogen + progestogen and are the most widely used contraceptive method worldwide:

• Usage: Take daily at the same time, 21 days on, 7 days off (or 24/4 depending on type)
• Effectiveness: 99% with perfect use, 91% in practice
• Additional benefits: Regulate menstruation, reduce cramps, reduce acne, lower risk of ovarian and endometrial cancer
• Side effects: Nausea, headache, breast tenderness (usually subsides after 2-3 months), rare venous thrombosis
• Cost: 30,000 - 150,000 VND/month depending on brand

ABSOLUTELY DO NOT USE when:

• Breastfeeding (less than 6 months postpartum)
• History of deep vein thrombosis or pulmonary embolism
• Over 35 years old + smoking
• Uncontrolled hypertension
• Migraine with focal neurological aura
• Current severe liver disease

Progestogen-Only Pill (mini-pill)

• Safe while breastfeeding — does not affect milk supply
• Must be taken very precisely on time (maximum 3-hour deviation from fixed time)
• Best for: Women who cannot use estrogen, breastfeeding mothers, smokers over 35
• Side effects: Irregular bleeding, especially in the first 3 months

Methods for Each Encounter

Condoms

Condoms are the only method that provides both contraception and protection against sexually transmitted diseases (STDs/STIs):

Male condoms:

• Contraceptive effectiveness: 82% typical use, 98% with perfect use
• Available at pharmacies and supermarkets
• No prescription needed
• Note: Check expiration date, do not use with oil-based lubricants (damages latex)

Female condoms:

• Effectiveness: 79% typical use
• Give women more control over protection
• Less common in Vietnam, harder to find

Emergency Contraception

Emergency contraception (also called the “morning-after pill”) is NOT a regular contraceptive method:

• Timing: Use as soon as possible after unprotected intercourse, maximum 72 hours (some types up to 120 hours)
• Effectiveness: 85-95% if used within the first 24 hours, decreasing over time
• Mechanism: Suppresses or delays ovulation
• Side effects: Nausea, vomiting, headache, menstrual irregularity for 1-2 months
• WARNING: Frequent use of emergency contraception (multiple times/month) causes severe hormonal disruption, prolonged menstrual disorders, and decreasing effectiveness

Natural Methods — Use with Caution

Rhythm Method

• Low effectiveness: Only 76% in typical use
• Only suitable for women with very regular cycles (28-30 days)
• Avoid intercourse or use condoms during ovulation days (days 12-16 of the cycle)
• Not recommended for women with irregular periods

Withdrawal

• Very low effectiveness: 78% in typical use
• Depends entirely on the male partner
• Sperm may be present in pre-ejaculatory fluid
• Not considered a reliable contraceptive method

Sterilization — Permanent Methods

Female sterilization (tubal ligation)

• Effectiveness: 99.5%
• Laparoscopic surgery, 1-2 day hospital stay
• Permanent — very difficult to reverse
• Should only be performed when you are certain you do not want more children

Male sterilization (vasectomy)

• Simpler than female sterilization
• Outpatient procedure with local anesthesia
• Need supplementary contraception for the first 3 months (waiting for existing sperm to clear)

Postpartum Contraception — An Issue Many New Mothers Overlook

Many women believe that breastfeeding prevents pregnancy, but this is not entirely true. The lactational amenorrhea method (LAM) is only effective when:

• Exclusively breastfeeding (no supplementary feeding)
• Menstruation has not returned
• Baby is under 6 months old

If all 3 conditions above are not met, additional contraception is needed. Methods safe while breastfeeding include: implants, IUDs (both types), and mini-pills. Do not use combined oral contraceptives (containing estrogen) in the first 6 months of breastfeeding.

Guide to Choosing the Right Method

Common Misconceptions About Contraception

1. “Breastfeeding means you can’t get pregnant” — False. LAM only works when all 3 strict conditions are met.
2. “Vaginal douching after sex prevents pregnancy” — Completely ineffective and can cause infections.
3. “Taking birth control pills for years causes infertility” — Not true. Fertility returns within 1-3 months after stopping.
4. “Emergency contraception can replace daily pills” — Very dangerous, causes severe hormonal disruption.
5. “IUDs are only for women who’ve had children” — False. Women without children can also use IUDs (small Multiload or Mirena mini).

When Should You See a Doctor?

You should visit for a gynecological exam for contraception counseling when:

• Unsure which method to choose — the doctor will assess your health and advise
• Want to switch contraceptive methods — need guidance for a safe transition
• Experiencing side effects from your current method: prolonged bleeding, headaches, significant weight gain
• Just had a baby — need advice on methods suitable for breastfeeding
• After miscarriage or abortion — need contraception immediately to protect your health
• Suspect an unplanned pregnancy — need confirmation and counseling
