The objective was to determine potential demand for, and satisfaction with, the SDM. Methods A total of 657 couples were selected by systematic sampling and offered the SDM. Those accepting this method were interviewed 1 and 3 months after starting the SDM. Results Some 47% of the participants were satisfied with the method and intended to continue using it. Conclusions Potential demand for the SDM was 80.3% (278/346 eligible women) among couples who were using a method of low effectiveness or no family planning method. Our results suggest that adding the SDM to the contraceptive method mix may benefit Turkish women.
