The Short Answer
Hormonal birth control uses synthetic hormones (estrogen, progestin, or both) to prevent pregnancy. Non-hormonal methods work through physical barriers or other mechanisms. Hormonal options tend to be more effective and offer benefits like lighter periods and less acne. Non-hormonal options avoid hormone-related side effects entirely. Neither category is universally better - it depends on your health history, your body's response to hormones, and what trade-offs you are willing to accept.
Key Points:
- Hormonal methods include: pills, IUDs (hormonal), implant, patch, ring, shot
- Non-hormonal methods include: copper IUD, condoms, diaphragm, fertility awareness
- The copper IUD is the only non-hormonal option with 99%+ effectiveness
- Hormonal methods can improve periods, acne, and PMS
- Non-hormonal methods avoid mood changes, weight fluctuation, and other hormonal effects
What Counts as Hormonal?
All hormonal methods use one or both of two synthetic hormones:
- Estrogen (usually ethinyl estradiol): helps prevent ovulation and stabilize the uterine lining.
- Progestin (various types): thickens cervical mucus, thins the uterine lining, and in some cases prevents ovulation.
Combined methods (estrogen + progestin): pill, patch, ring.
Progestin-only methods: mini pill, hormonal IUD, implant, shot.
Progestin-only methods tend to have fewer systemic side effects because they skip estrogen. The hormonal IUD delivers progestin mostly locally, so very little enters the bloodstream.
What Counts as Non-Hormonal?
- Copper IUD: copper ions create a sperm-hostile environment in the uterus.
- Condoms (male and female): physical barriers that block sperm.
- Diaphragm/cervical cap: barrier devices used with spermicide.
- Fertility awareness methods (FAM): tracking your cycle to identify fertile windows.
Side-by-Side Comparison
| Factor | Hormonal | Non-Hormonal |
|---|---|---|
| Most effective option | Implant (99.95%) | Copper IUD (99.2%) |
| Affects your cycle | Yes - often lighter or absent periods | Copper IUD may increase flow; others do not affect it |
| Mood/weight effects | Possible, especially first 2-3 months | None from the method itself |
| Acne | Often improves (combined methods) | No effect |
| STI protection | No | Only condoms |
| Requires prescription | Most do | Copper IUD does; condoms do not |
Reasons to Choose Hormonal
- You want lighter, more predictable periods (or no periods at all).
- You want help with acne, PMS, or endometriosis symptoms.
- You want the highest-effectiveness options available (implant, hormonal IUD).
- You are comfortable monitoring for hormonal side effects during the adjustment period.
Reasons to Choose Non-Hormonal
- You have experienced negative hormonal side effects (mood changes, low libido, weight gain).
- You have a medical condition that makes estrogen unsafe (blood clot history, migraine with aura, certain cancers).
- You prefer not to introduce synthetic hormones into your body.
- You want STI protection (condoms are the only option here).
- You want the longest-lasting single device (copper IUD: 10-12 years).
The "In-Between" Option
The hormonal IUD is sometimes called a middle ground. It uses progestin, so it is technically hormonal, but the hormone is delivered locally to the uterus. Blood levels of progestin are much lower than with pills, patches, or the shot. Many people who are sensitive to systemic hormonal side effects tolerate the hormonal IUD well.
Can You Combine Methods?
Yes. A common combination is a hormonal method (for pregnancy prevention) plus condoms (for STI protection). This is especially useful in new relationships or when either partner's STI status is unknown.
Frequently Asked Questions
Is non-hormonal birth control less effective?
Not necessarily. The copper IUD is 99.2% effective - comparable to hormonal IUDs. However, other non-hormonal methods (condoms, FAM, withdrawal) have lower typical-use effectiveness rates.
Will my periods go back to normal after stopping hormonal birth control?
For most people, periods return within 1-3 months. The exception is the shot (Depo-Provera), which can delay period return for 6-12 months. More on switching methods.
Can I switch from hormonal to non-hormonal?
Yes. The most common switch is from pills to a copper IUD. Your provider can usually insert the copper IUD on the same day you stop the pill. Read our switching guide.
Do non-hormonal methods affect fertility?
No. Non-hormonal methods do not affect your long-term fertility. Once you stop using them, your fertility returns to its natural baseline immediately.
