With an insertion of an IUD (intrauterine device), female or male sterilization, or hormone implant, there is very little required of the user post initial procedure; there is nothing to put in place before intercourse to prevent pregnancy.] Intrauterine methods require clinic visits for installation and removal or replacement (if desired) only once every several years (5-12), depending on the device. This allows the user to be able to try and become pregnant if they so desire, upon removal of the IUD. Conversely, sterilization is a one-time, permanent procedure. After the success of surgery is verified (for vasectomy), no subsequent action is usually required of users.
