Background and Aim: Rapid growth of Iran's population attracted attention of the authorities after the 1986 national census. This led to population control and family planning programs to be considered as a priority. Appropriate strategies of the family planning program led to a very fast decrease in population growth and fertility indices: and use of contraceptive techniquies rate increased from 49% in 1989 to 73.8% in 2007. This study aimed at reviewing family planning program in Iran (FPPI) during the last four decades and discussing the reasons for its success, as it can be a guide for future efforts aimed at improving other aspects of reproductive health.

Materials and Methods: The method used was systematic reviewing of articles indexed in Medline and University Jihad Scientific Database, reports of the Demographic and Health Project, the Iranian Statistical Center National Censuses, and the Ministry of Health and Medical Education reports on knowledge, attitude and practice.

Results: FPPI initiated officially in 1966 faced with limited success. Following the 1986 national census, population control was announced as a public policy, supported by the leaders. A supportive environment was created by mass media. Establishment of the Departments of Population and FP in the Ministry of Health made possible reorganizing family planning services: expanding coverage of PHC services, including FP services training skilled personnel providing free contraceptives and vasectomy and tubectomy services. Involvement of volunteers and NGOs helped in strengthening community actions. In order to develop personal skills, in addition to face-to-face FP counseling in the health centers, FP education in schools, colleges, workplaces, army and pre-marriage classes was also imparted. Promotion of men's participation in FPPI, by providing male methods of contraception, such as vasectomy or condom use, was also considered. There was also cooperation and support on the part of nongovernmental and international organizations.

Conclusion: Based on the findings, it may be concluded that the principles of health promotion can explain the FPP achievements in Iran. This model can be used in expanding other reproductive health programs in Iran.

Background and Aim: The time needed to achieve a wanted pregnancy is referred to as time to pregnancy (TTP). Due to differences in lifestyles and geographical locations in different countries, factors affecting TTP may be different in various countries. This study was conducted in 2011 to determine factors affecting time to TTP in Kermanshah, Iran.
Materials and methods: In this case-control study 174 women with TTP>12 months (cases) and 587 women with TTP<=12 months (controls) were selected. The tool for collecting data was a questionnaire. The SPSS-16 software was used for data analysis, a p-value <0.05 being considered as statistically significant.
]Results: Multivariate analysis showed that factors decreasing TPP statistically significantly were women's education level (≥high school diploma OR=0.854, CI 95%=0.741-0.984), frequency of intercourse in a week (OR=0.728, CI95%=0.631-0.839), blood group A compared to O (OR=0.639, CI95%=0.405-1.01), and non-exposure to smoking (OR=0.606, CI95%=0.380-0.965). On the other hand, factors increasing TPP were a woman's irregular menstrual cycle (OR=3.701, CI95%=2.127-6.441), lack of physical activity (OR=1.920, CI95%=1.263-2.918) and a body mass index (BMI) higher than 25 (OR=2.221, CI 95%=1.489-3.312).
Conclusion: According to the results of this study, a high BMI and lack of exercise increase, while factors such as frequency of intercourse decrease the length of TTP. Couples seeking medical intervention for pregnancy often disregard factors associated with TTP. It is recommended that care-providers support these couples, promote their awareness, and give them suitable advice.

Background and Aim: Delays in childbearing, in addition to creating health risks for the mother and the child, may lead to permanent parental bereavement. The purpose of this study was psychometric assessment of the validity and reliability of the Iranian version of attitude toward reproductive and childbearing inventory (ATRCI) in women without a history of pregnancy.
Materials and Methods: This study was done on 235 women without a history of pregnancy selected by multi-stage sampling in the South of Iran. They completed a fertility and childbearing attitude questionnaire. The validity and reliabilty of the ATRCI were determined using SPSS-16 software, the statitical tests being Cronbach's alpha coefficient and exploratory factor analysis.
Results: The mean age of the women was 24.47 ± 4.1 years, and the Cronbach's alpha total coefficient was 0.888. The KMO and Bartlett's test of sphericity value (0.890) was  significant.
In this study, in addition to the main components of the questionnaire, the childbirth postponement component was also extracted; they explained  63.01% of the total variance related the attitude toward fertility and childbearing. 
Conclusion:  The 4-component Iranian version of the attitude toward fertility and childbearing inventory was found to have acceptable psychometric validity and reliability. It is recommended that in the future studies this inventory be used in intervantional studies and heath and demographic programs for women without a history of pregnancy.

Background and Aim: Fertility declining to a level too low for replacement and preventing its negative consequences have led to changes in the country's population policies. Understanding the causes of declining fertility and proper policymaking to increase it requires prompt action on the part of researchers and policymakers in different social and health fields. The purpose of this study was to investigate the effect of different components of perceived social support  ̶  instrumental support, material support and emotional support  ̶  on women's fertility intention. 
Materials and Methods: This was a survey conducted in the suburban areas of Bushehr Province, Iran. Using multi-stage cluster sampling a total of 600 eligible women aged 18-44 years old were selected. The questions used to measure fertility intention and social support dimensions of the women were extracted from the standard questionnaire used in international research.

The questions used to measure fertility intention and social support dimensions of the women were extracted from the standard questionnaire used in international research.
Results: The data showed that about 89% of those women who had had one child declared their intention to have a second child, while only 38% of those with 2 children had the intention to have a third child. Multivariate analysis using logistic regression indicated that increased instrumental support will, through controlling the number of currently living children, their education and employment status, increase the likelihood of women's fertility intentions to 1.445.
Conclusion: The instrumental support and the relevant support that can be obtained from social network members can facilitate the transition to higher fertility sequences.
