The pill and condom are very common. Other alternatives are IUDs, both hormonal and copper, which are effective for a long time. Sponges, jellies, and spermicidal films are a messier option. Diaphragms are also fairly effective. Vasectomy and tubal ligation are slightly more permanent methods. The female condom is a less popular barrier method and is slightly less effective.
