Abstract

Introduction: Infertility is one of the most common disorders in modern societies, especially in developing countries. Temperament (Mizaj) as one of the indicators of Persian medicine represents the systemic status of the individual that can affect the fertility status of couples. This study was conducted with aim to assess the effect of temperament of fertile and infertile couples on their infertility in the population of North Khorasan province.
Methods: In this case-control study, the records of fertile and infertile couples referring to obstetrics and gynecology centers in North Khorasan Province were reviewed. The required information was extracted from the couples’ records in two groups of fertile and infertile and the temperament type of the participants was determined with the psychometric Salmannejad temperament questionnaire, and analyzed using the frequency distribution and odds ratio and confidence interval for the odds ratio, which is an indicator of determining the relationship between exposure and outcome in case-control studies, with a confidence level of 95%.
Results: In temperament assessment of 240 couples (120 fertile and 120 infertile couples,) cold and wet temperament was the most common in the infertile group (CI 95%= 1.25-3.0 and OR=1.95) and warm and wet temperament was the most common in the fertile group (CI95%=0.23-0.61 and OR=0.37) (27.5% and 25.4%, respectively). In other words, in people with a cold and wet temperament, the risk of infertility is 95% higher than other temperaments, and since the confidence interval does not include 1, it was statistically significant. Based on the available data, a warm and wet temperament is 63% more protective against infertility than other temperaments.
Conclusion: Based on the available data, cold and wet temperament is the most common type in infertile couples in North Khorasan province. Also, warm and wet temperament and warm and dry temperament play a role in protecting against infertility. The results of this study showed that a person's dystemperament can be effective as a risk factor in the occurrence of infertility.
