Copper IUDvsTubal Ligation

A side-by-side comparison of two birth control methods — efficacy, cost, how they work, and who shouldn't use them.

Side-by-side comparison

Method	Copper IUD A small copper device placed in the uterus that works for up to 10 years and is over 99% effective.	Female Sterilization A permanent surgical procedure that blocks or removes the fallopian tubes to prevent pregnancy.
Efficacy	99.2% typical use Most effective: over 99 out of 100 people successfully prevent pregnancy per year.	99.5% typical use Most effective: over 99 out of 100 people successfully prevent pregnancy per year.
Cost	$0–$1,424 Insurance: Usually	$0–$6,000 Insurance: Usually
Duration	Up to 10 years	Permanent
Reversibility	Reversible	Permanent
STI Protection	No	No
How it works	Releases copper ions into the uterus that make the environment toxic to sperm and may prevent implantation if fertilization occurs.	Surgical disruption (clipping, banding, cauterization, or complete removal) of the fallopian tubes prevents eggs from reaching the uterus and sperm from reaching the egg.
Prescription	Required Prescription required	Required Prescription required
Side effects	Heavier or longer periods (especially first few months) Increased cramping Spotting between periods Small risk of uterine perforation at insertion	Surgical risks (bleeding, infection, organ damage) Anesthesia side effects Ectopic pregnancy (small but serious risk if failure occurs)
Who shouldn't use this	Active pelvic infection or PID (FDA label) Uterine anomaly preventing insertion (FDA label) Wilson's disease (copper metabolism disorder) (FDA label) Known copper allergy (FDA label) Current pregnancy (FDA label)	Medical instability for general anesthesia or laparoscopy Uncertainty about future fertility desires

Key differences

Female Sterilization is more effective (99.5% vs 99.2% typical use). Copper IUD duration: Up to 10 years. Female Sterilization duration: Permanent. Copper IUD is reversible; Female Sterilization is permanent. Copper IUD: costs $0–$1,424. Female Sterilization: costs $0–$6,000.
