ABSTRACT
The cervical cap is a convenient, inexpensive, nonhormonal and non-invasive contraceptive method. This method has potential for better effectiveness if custom-fit caps are manufactured. As more health care providers become knowledgeable in the use of the cap, more women will become aware of this contraceptive method as an alternative to oral contraceptives and intrauterine devices. Research is needed to document the most accurate method of cervical cap fitting and the effectiveness rate of the cervical cap. Nurse practitioners who counsel patients and fit them for caps are in the perfect position to start doing this research.
PIP: Users have frequently complained about the inherent disruptiveness, expense, and messiness of barrier methods of contraception. The cervical cap seems to eliminate many of the previously cited disadvantages of barrier contraception. The cap does not interfere with intercourse, does not require daily client involvement, and is nonhormonal and noninvasive. The disadvantages connected with its use are that it requires precise individual fitting, it is not yet manufactured in the U.S., it takes time to learn proper placement, and it depends on the individual female anatomy. Despite wide use in Europe since the 19th century, the cervical cap is rarely used or discussed as a contraceptive in the U.S. Statistics cited from various studies of barrier methods in general give the cap an effectiveness range from 85-98%; these effectiveness ratings are for all vaginal barrier devices together so it is difficult to judge the cervical cap specifically. The device's effectiveness will vary according to various psychological and physiological user characteristics. Each of the following 3 types of cervical cap is described and diagrammed: 1) Dumas cap; 2) cavity-rim cap; and 3) Vimule cap. There is a need for health care providers and contraceptive counselors to better acquaint themselves with the cervical cap. Evaluation research on its effectiveness is needed.
