Background: The time required to achieve the pregnancy is called time to pregnancy (TTP). The effective factors on TTP are different because of the different life style and geographical condition in various countries. The present study aimed to determine the effective factors on TTP in Kermanshah in 2010. Method: In this case-control study, 174 mothers with TTP ≥ 12 months and 587 mothers with TTP < 12 months were selected as case and control group, respectively. A questionnaire was used for data collection. The data were analyzed by SPSS, V.16 software and p < 0.05 was considered as significance level. Results: Based on the results of Multi-variant analysis, women education level (Diploma and higher)( OR-0.854, CI 95% = 0.741-0.984), increasing intercourse frequency per week (OR = 0.728, CI 95% = 0.631-0.839), not exposure to smoking (OR=0.606, CI 95%=0.380-0.965) and blood group A compared to O (OR = 0.639, CI 95% = 0.405-1.01) significantly reduced TTP. Some factors as BMI>25kg/m2 (OR=2.221, CI 95%=1.489-3.312), irregular menstrual (OR=3.70, CI 95%=2.127-6.441) and the lack of doing sport activities among females (OR=1.920, CI95%=1.263-2.918) increased TTP. Conclusion: Based on the results of this study, some factors as high BMI and the lack of doing sport activities increased TTP and some factors as increasing the intercourse frequency per week reduced its chance. The couples who plan for pregnancy and follow medical interventions don’t consider the factors of TTP. It is recommended that health care staffs support the couples and give them the required consultations
