How effective are different kinds of birth control? do they have side effects?

See below: Tubal ligation/vasectomy 99.9% effective. Depoprovera/iud 99% effective, birth control pills 95% effective, condom/diaphragm 90 % effective.

IUDs and implants: You should consider long-acting reversible contraceptives (larc)--iuds and a small rod placed under the skin. All very effective (the most effective methods--as effective as sterilization), and last 5 or 10 years (iuds) or 3 years (implant). Low rates of side effects, and the hormone iud has low levels of hormones and benefits of lighter periods. See table: http://www.Contraceptivetechnology.Org.
