Pill (estrogen & progestin)		Progestin intrauterine system (Mirena)
Three-month pill (Seasonale)		Diaphragm
Patch (Ortho Evra)		Cervical cap
Ring (NuvaRing)		Surgical sterilization
Mini-pill (progestin only)		Transcervical sterilization (Essure)
Injection (Depo-Provera)		Spermicides
Male condom		Periodic abstinence
Female condom		Vasectomy
Copper intrauterine device (ParaGard)
