Hormonal Contraception
How Hormonal Contraceptives Work: – Suppress ovulation – Thicken cervical mucus (blocks sperm) – Thin endometrium (prevents implantation) – Combination: Estrogen + progestin – Progestin-only: No estrogen
Brands: Yaz, Ortho, Levora, and many others
Types: – Monophasic: Same hormone dose all month – Biphasic: Two different hormone doses – Triphasic: Three different hormone doses – Extended-Cycle: Fewer placebo pills (fewer periods) – Continuous-Cycle: No period month
How to Use: – Take pill at same time daily – 21 active pills + 7 placebos (traditional) – Or all active pills (continuous)
Effectiveness: – Perfect use: 99% – Typical use: 91% – Very effective with consistent use
Benefits: – Lighter, shorter periods (or no periods) – Reduced cramps – Improves PCOS symptoms – Regulates irregular cycles – Reduces acne – Protects against ovarian and endometrial cancer – Reduces benign breast cysts – Reversible
Drawbacks: – Must remember daily – Nausea (especially first weeks) – Breast tenderness – Headaches – Mood changes – Reduced libido (some women) – Blood clot risk (rare, increased with smoking/age) – Migraine with aura: Slightly increased stroke risk – Not immediately reversible (takes 1-3 months to conceive)
Brands: Camila, Nor-QD, Heather
How It Works: – Progestin only (no estrogen) – Thickens cervical mucus mainly – Does NOT consistently suppress ovulation
How to Use: – Pill every day (no placebo pills) – Must be taken at same time (3-hour window) – More forgiving if missed
Effectiveness: – Perfect use: 99% – Typical use: 91% – Slightly less effective than combined pill
Benefits: – No estrogen (safer with certain conditions) – Can use while breastfeeding – Minimal hormones – Lighter or no periods – Reduced hormone-related side effects
Drawbacks: – Must take at exact time daily – Irregular bleeding common – Less effective than combined pill – Doesn’t regulate cycles as well – Similar cost to combined pill

How It Works: – Intramuscular progestin injection – Prevents ovulation – Thickens cervical mucus – Lasts 12 weeks (gets every 3 months)
Effectiveness: – Perfect use: 99% – Typical use: 97% – Very effective (no compliance needed)
Benefits: – No daily pill to remember – No hormones between shots – Periods often stop (80% within 12 months) – Very effective – Reversible
Drawbacks: – Weight gain (average 2 kg after 1 year) – Irregular bleeding initially – Delayed return to fertility (6-18 months after last shot) – Must remember appointments – Not for women wanting quick pregnancy – Reduced bone density (reversible) – Requires office visits
Hormone Patch and Ring
Patch (Ortho Evra): – Sticky patch delivering hormones – Changed weekly for 3 weeks – Patch-free week for period – Effectiveness: 91% typical use – Benefits: Weekly reminder instead of daily – Drawbacks: Visible, skin irritation possible

Drawbacks: – Insertion uncomfortable (brief) – Spotting and irregular bleeding first 3-6 months – May cause cramping – Requires insertion procedure – Cost upfront (insurance usually covers) – Small risk of expulsion – Doesn’t protect against STIs
How It Works: – Copper toxic to sperm – Inflammatory response prevents implantation – No hormones
Duration: – 10-12 years
Effectiveness: – 99.4% (highly effective)
Benefits: – No hormones – Longest-lasting – Reversible – Safe while breastfeeding – Can be used for emergency contraception – Doesn’t affect bone density – Safe with certain medical conditions – No significant systemic effects
Drawbacks: – May increase period flow and cramping – Irregular bleeding common first months – Insertion uncomfortable – Cost upfront – Risk of expulsion – Copper allergy (rare) – Doesn’t protect against STIs

Drawbacks: – Irregular bleeding (common initially) – Some women experience constant spotting – Small surgical insertion/removal – Cost upfront – Visible bump under skin (minimal) – Insertion/removal must be professional
Barrier Methods
Male Condom

Factors to Consider:
Effectiveness Needed: – How important is contraceptive efficacy? – Accept occasional failures or need very reliable?
Frequency of Use: – Daily pill? Or long-term methods? – Convenience important?
Menstrual Changes: – Want lighter or no periods? – Want unchanged cycles?
Side Effects: – Tolerate hormonal side effects? – Prefer non-hormonal?
Hormones: – Breastfeeding? (progestin-only options) – Medical conditions contraindicated hormones?
STI Protection: – Need protection against STIs? – (Only condoms provide this)
Cost: – Insurance coverage? – Ability to pay out of pocket?
Return to Fertility: – Need quick return to fertility? – Can wait 6-18 months?
Permanence: – Want reversible or permanent?
Partner Involvement: – Does partner support choice? – Partner-dependent method?
The best contraceptive is the one you’ll use correctly and consistently. There’s no one-size-fits-all answer. For women in long-term relationships wanting maximum effectiveness, IUDs or implants are excellent choices. For those needing STI protection, condoms combined with another method work well. We discuss your individual needs to find what’s right for you.
When to Revisit Contraception Choice
Consider Changing If: – Current method causing significant side effects – Difficulty with compliance – Concern about effectiveness – Desire to change timing of periods – Concern about STI risk – Change in relationship status – Planning for pregnancy – Significant health changes – Cost becomes prohibitive
The Bottom Line
Choosing contraception is personal. Understanding your options, their effectiveness, benefits, and drawbacks empowers you to make the best choice for your life and health.
Make an informed choice. Choose what’s right for you.
