Contraceptive Options in Singapore

A wide range of contraceptive methods is available in Singapore, including short-term, long-acting, hormonal, and non-hormonal options. Different contraceptives work in different ways — such as preventing ovulation, thickening cervical mucus, or affecting the uterine environment — and suitability varies depending on your health profile, lifestyle, and future family planning goals.

Because each method has different considerations, effectiveness profiles, and potential side effects, a consultation with a doctor can help determine which option may be most appropriate for your individual needs.

Short-Acting Hormonal Contraceptives

Short-acting hormonal contraceptives require regular user action, such as daily, weekly, or monthly use. They work primarily by preventing ovulation, thickening cervical mucus, or both.

Combined Oral Contraceptive Pill

The combined oral contraceptive pill contains oestrogen and progestogen. It works mainly by preventing ovulation and thickening cervical mucus.

Its effectiveness depends on consistent daily use. It may also help regulate menstrual cycles and improve acne in some individuals. It may not be suitable for those with certain medical conditions, including specific cardiovascular risk factors.

Progestogen-Only Pill

The progestogen-only pill, sometimes referred to as the “mini-pill”, primarily works by thickening cervical mucus. Depending on the formulation prescribed, the pill may need to be taken within a specific daily time window to maintain contraceptive reliability. Some individuals may experience irregular bleeding patterns, particularly during the first few months of use.

Contraceptive Patch

The contraceptive patch is a combined hormonal method applied to the skin and changed weekly. It releases hormones that are absorbed into the bloodstream to prevent pregnancy.

Vaginal Ring

The vaginal ring is a flexible device inserted into the vagina for three weeks at a time, followed by a ring-free interval. It releases hormones locally that are absorbed systemically to prevent ovulation.

Long-Acting Reversible Contraceptives

Long-acting reversible contraception provides extended protection without the need for daily or frequent action. Fertility generally returns after removal or discontinuation.

Intrauterine Devices (IUDs)

IUDs are small devices inserted into the uterus by a healthcare professional during a brief outpatient procedure.

Copper IUDs

The copper IUD is a hormone-free contraceptive that works by reducing sperm movement and survival within the uterus. It may also be used as emergency contraception if inserted within a specific timeframe after unprotected intercourse.

Menstrual bleeding may become heavier or more crampy, especially in the first few months after insertion.

Hormonal IUDs (Mirena)

The hormonal IUD, commonly known as Mirena, releases a small amount of levonorgestrel locally within the uterus. It may reduce menstrual bleeding over time, and some individuals may experience very light or absent periods. Its effects are primarily local, with minimal systemic hormone exposure.

Clinical Note: At AOGC, hormonal IUDs (Mirena) are commonly used in clinical practice due to their benefits in menstrual regulation. However, suitability varies between individuals, and a consultation is required to determine whether a hormonal or copper IUD is more appropriate based on your medical history and needs.

Contraceptive Implants

The contraceptive implant is a small rod placed under the skin of the upper arm. It releases progestogen continuously for up to three years. It is a reliable long-acting contraceptive option. Changes in menstrual patterns are common and may include irregular bleeding or absence of periods.

Contraceptive Injections

Injectable contraception provides protection for approximately 12 weeks per dose. It is a discreet option that does not require daily adherence. After stopping, the return of fertility may be delayed. Long-term use may be associated with reduced bone mineral density, so ongoing use is usually reviewed periodically by a doctor.

Barrier Methods

Barrier methods physically prevent sperm from reaching the ovum. Condoms are also the only contraceptive method that helps reduce the risk of sexually transmitted infections (STIs).

Male and Female Condoms

Male condoms provide contraception and STI protection when used correctly and consistently. They are available in latex and non-latex options.

Female condoms offer a woman-controlled barrier method. They can be inserted prior to intercourse and do not require partner participation. Correct use may require some familiarity and practice.

Diaphragms and Cervical Caps

These are silicone barrier devices used with spermicide to cover the cervix.

They must be fitted by a healthcare professional to ensure correct sizing and effectiveness. They are inserted before intercourse and left in place for several hours afterwards. They do not provide STI protection.

Non-Hormonal / Behavioural Methods

Fertility Awareness Methods

These methods involve tracking the menstrual cycle using indicators such as basal body temperature, cervical mucus, and cycle timing.

Effectiveness depends on consistent and accurate tracking. Additional contraception is required during fertile periods, especially in individuals with irregular cycles.

Permanent Contraception

Female Sterilisation

Female sterilisation involves blocking or sealing the fallopian tubes to prevent pregnancy. It is performed via minimally invasive surgery. It is generally considered a permanent method of contraception. Reversal procedures are complex and not always successful.

Male Sterilisation (Vasectomy)

Vasectomy involves blocking or cutting the vas deferens (the tubes that carry sperm from the testicles), preventing sperm from entering semen.

It is usually performed under local anaesthesia in an outpatient setting by a urologist. Alternative contraception is required until semen analysis confirms the absence of sperm, typically around 8–16 weeks after the procedure.

Special Considerations

Breastfeeding

Exclusive breastfeeding may provide some contraceptive effect during the first six months postpartum if menstruation has not resumed, and feeding occurs regularly, including overnight. However, additional contraception may still be considered depending on individual circumstances.

Progestogen-only methods — including the mini-pill, implant, hormonal IUD, and injection — are generally considered compatible with breastfeeding. Combined hormonal methods may affect milk supply and are therefore usually introduced later in the postpartum period, depending on individual risk factors and breastfeeding status.

Medical Conditions

Certain medical conditions may influence contraceptive suitability. A doctor can recommend appropriate options based on your medical history, current health conditions, and individual risk factors.

Examples include:

• Migraine with aura: Combined hormonal methods may increase stroke risk in some individuals
• Blood clotting disorders: Oestrogen-containing contraceptives may not be suitable
• Liver disease: Some hormonal contraceptives are metabolised through the liver
• History of breast cancer: Certain hormonal methods may not be recommended
• Cardiovascular disease: Some hormonal methods may affect clotting, and blood pressure

Medications

Some medications may reduce the effectiveness of hormonal contraception. These include certain anti-epileptic medications and rifampicin-based antibiotics commonly used to treat tuberculosis. Most routinely prescribed antibiotics do not significantly affect contraceptive effectiveness.

A medication review during consultation helps determine whether additional contraceptive precautions are required.

Choosing A Contraceptive Method

Choosing a contraceptive method in Singapore typically involves balancing medical suitability, lifestyle preferences, and future reproductive plans.

Lifestyle and Daily Routine: Methods requiring daily action may suit individuals with consistent routines. Those with irregular schedules or frequent travel may prefer longer-acting options that require less maintenance.

Menstrual Preferences: Different contraceptive methods may affect menstrual patterns differently. Hormonal IUDs and certain hormonal methods may reduce menstrual bleeding over time, while copper IUDs may increase bleeding or cramping in some individuals.

Future Pregnancy Plans: Individuals planning pregnancy in the near future may prefer methods with a rapid return to fertility after stopping contraception. Others may consider longer-acting reversible methods.

Side Effects Considerations: Previous experiences with hormonal contraception may influence future choices. Some individuals may prefer non-hormonal methods if they are sensitive to hormonal side effects.

Partner Involvement: Some contraceptive methods require partner participation, while others are controlled entirely by the individual using them. Preferences vary depending on personal circumstances and relationship dynamics.

When to Seek Professional Help

Seek medical review if you experience any of the following while using contraception:

• Severe headaches or visual disturbances while using hormonal contraception
• Leg pain, swelling, or shortness of breath
• Heavy vaginal bleeding, particularly if soaking through pads frequently over several hours
• Inability to feel the IUD strings after previously being able to locate them
• Persistent side effects that affect daily activities or quality of life
• Difficulty using your current method or concerns about suitability
• A desire to review or change your contraceptive method based on changing health or lifestyle needs

Commonly Asked Questions

Can I switch contraceptive methods at any time?

Contraceptive methods can generally be changed at any stage, though the timing of the switch may affect continuous contraceptive protection. Some methods require overlap or backup contraception during the transition period. Our gynaecologist can advise on the safest timing and approach based on your current method and menstrual cycle.

How soon does fertility return after stopping contraception?

Fertility typically returns relatively quickly after stopping most contraceptive methods. However, the timeline varies between individuals and depends on the method used.

For contraceptive injections, the return of fertility may take longer compared to other methods, sometimes several months after the final dose.

Do contraceptives protect against sexually transmitted infections (STIs)?

Male and female condoms are currently the only contraceptive methods that also help reduce the risk of sexually transmitted infections (STIs) when used correctly and consistently. Other contraceptive methods primarily prevent pregnancy and do not provide STI protection.

Will hormonal contraception cause weight gain?

Responses to hormonal contraception vary between individuals. Some people may notice changes in weight, fluid retention, or appetite, while others may not experience noticeable changes.

Current evidence does not consistently show significant weight gain with most hormonal contraceptive methods.

What if I want contraception but have never had a gynaecological examination?

Many contraceptive methods do not require an internal examination before prescription. Options such as oral contraceptives, patches, rings, injections, and implants may often be discussed based on medical history and suitability assessment alone.

However, procedures such as IUD insertion or diaphragm fitting require a clinical examination and in-clinic procedure.

Next Steps

No single contraceptive method is suitable for everyone. The most appropriate option depends on factors such as your medical history, lifestyle preferences, reproductive plans, and tolerance for potential side effects.

Certain medical conditions — including migraine with aura, blood clotting disorders, cardiovascular disease, or a history of hormone-sensitive cancers — may influence contraceptive suitability. While many methods are effective for pregnancy prevention, only male and female condoms also help reduce the risk of sexually transmitted infections (STIs).

A consultation with our qualified obstetrician and gynaecologist can help assess which contraceptive method is appropriate for your individual circumstances.
