Contraception Methods: 8 Options Compared
Pills, IUDs, condoms, implants, FAM and others — efficacy, side effects, and usage guide.

Contraception is personal — there is no "best method," only "most suitable method for you." This guide compares 8 main methods in terms of efficacy, ease of use, side effects, reversibility, and cost. Doctor consultation is essential — chronic disease, smoking, age, and pregnancy plans affect choice.
Efficacy (Pearl Index — pregnancies per year per 100 users):
- Difference between perfect use and real-world use
- Most effective: implant (0.05), tubal ligation and vasectomy (0.5), hormonal IUD (0.2), copper IUD (0.8)
- Very effective: COC pill (0.3 perfect / 7-9 real), injection, ring
- Effective: condom (2 perfect / 13 real), diaphragm
- Less effective: FAM/calendar (1-9 perfect / 24 real), withdrawal (4 / 22)
- Combined Oral Contraceptive (COC): Estrogen + progestin. Regulates periods, reduces dysmenorrhea, treats acne. Contraindications: smoker + over 35, migraine with aura, history of deep vein thrombosis, untreated hypertension, breast cancer history, before 6 weeks postpartum. Side effects: nausea, breast tenderness, libido change, rare thromboembolic event.
- Mini Pill (progestin only): When estrogen contraindicated, safe in breastfeeding. Must be taken at the same time every day; the allowed delay depends on the product (3 hours for some, 12-24 hours for others), so check your product's leaflet. Spotting common.
- Hormonal IUD (Mirena, Kyleena): Duration depends on the product (Mirena up to 8 years, Kyleena 5 years); can be forgotten after insertion. Periods decrease/stop (especially Mirena). Can be inserted within 48 hours of birth or from 4 weeks postpartum. Side effects: spotting in first 3-6 months, 5% expulsion (falling out) after insertion. Can be applied in nulliparous women.
- Copper IUD: Hormone-free; the duration of effect varies by model — TCu380A (Paragard) is effective for 10 years, while NovaT 380 is effective for 5 years; ask your doctor about the duration of the model placed. May increase period bleeding and cramps. 99% effective for emergency contraception within 5 days of insertion.
- Implant (Implanon, Nexplanon): 4 cm rod placed in upper arm, effective 3 years, progestin only. Period bleeding becomes irregular (20% amenorrhea). Most effective reversible method.
- Hormonal Ring (NuvaRing) / Patch (Evra): Used 3 weeks/month, 1 week break. Same contraindications as COC. Ring inserted by self.
- Barrier (Condom, Diaphragm, Spermicide): Condom is the only method that provides STI protection. Polyurethane alternative if latex allergy.
- Fertility Awareness (FAM/Natural): Basal body temperature + cervical mucus + calendar. Requires regular periods and discipline, very prone to user error. No emergency protection.
Permanent methods:
- Tubal ligation (woman): Laparoscopic, hard to reverse
- Vasectomy (man): Easier, cheaper, safer — also discuss your partner's options
Emergency contraception (after intercourse):
- Levonorgestrel pill (Norlevo, Postinor): within 72 hours, 85% efficacy
- Ulipristal acetate (EllaOne): within 120 hours, more effective
- Copper IUD (within 5 days): 99%
- Availability varies by country — levonorgestrel is sold over the counter at pharmacies in the US and UK; ulipristal may require a prescription
Dear woman, the "right" method varies by your needs, lifestyle, and health. Trying multiple methods is normal. During doctor visit: smoking status, chronic disease, pregnancy plan (1 year or 5 years?), period characteristics, expectations (less/no period?). The decision is yours, the doctor is your guide.
