Norplant is a commitment. Six thin plastic implants are put under the skin of your arm, and hormones are released constantly for 5 years to keep your ovaries from releasing eggs. The insertion is painless (except for the prick of the numbing needle), and it costs around $600. Norplant can be removed early, but removal costs about $150, and therefore, this method isn't worth it unless you plan on leaving the implants in for the full 5 years.
