History and Objectives: Population development is one of the major problems in many countries of the world and it is necessary to apply family planning strategies. In this regard, knowledge of reasons for agreement and opposition to apply these strategies is very effective. This study was carried out in rural areas of Kashan in 1997 to determine the reasons of opposition.

Materials and Methods: The descriptive strategy of this study was conducted on 520 married men with an age of 15-49 years in rural regions of Kashan. For collection of information, a questionnaire was filled out through interviewing.

Results: The most opposed method was vasectomy (79.5%) because of its possible complications (34%). For contraceptive method, its high rate of complications was mentioned as an opposing factor (51.9%). Unreliability of condom (51%) was the most opposing factor for this method. Illegality of tubectomy (24.8%) was the most opposing factor.

Conclusion and Recommendations: Considering the above-mentioned reasons, it is recommended to perform an experimental study to evaluate the effectiveness of health education on opposing factors to pave the way for attainment of goals regarding family planning.
