Barrier contraception: a comprehensive overview.

The barrier class of contraceptives used either alone or with supplementary spermicidal agents includes the most ancient of methods for the control of human fertility. Modern innovations have effected marked improvement in their efficacy and acceptability, so that they have become key means of controlling fertility in the world today. The traditional diaphragms and condoms decreased in popularity to some extent when methods such as the OCs and IUDs became available for general use. However, the plain or medicated barriers are regaining their rightful position in our contraceptive armamentarium as more and more questions are being raised about the real or potential adverse side effects of systemic and intrauterine contraceptives. There is evidence throughout the world of the growing popularity and use of locally acting mechanical and/or spermicidal contraceptive methods. Their impact upon the increasing world population can be expected to become even greater when the true need for the control of fertility becomes more generally recognized and appreciated.
