Why are additional contraceptives needed?
There is currently no reversible contraceptive that all women like and are able to use. A woman may try several methods until she finds the one that best suits her. Furthermore, a woman may switch methods several times during her reproductive lifetime because of changes in her age, health, economic security, marital status, lifestyle, and concept of ideal family size. All of these factors can have an impact on her decisions about contraception: when to use or stop using it, what kind to use, and when to switch to another method.
