Micronutrient deficiencies, such as vitamin D, along with disorder in fertility, are reported in some studies. The objective in this research is to study the vitamin D condition in infertile women during their reproductive ages, between 20 and 40 in Shiraz and determining their relation with demographic and social characteristics. In methodology 180 infertile women admitted in Qadir Mother and Child Hospital was selected through simple random sampling and studied variables were tested in them. Also, blood sample was taken from them and their serum 25-hydroxyvitamin D levels were measured through ELISA. In this research, the normal level for vitamin D was appointed to be greater than or equal to 30 ng/ml and the serum level lower than 30 ng/ml was considered to be the deficit level. In results research findings suggested that among the 180 studied women, 95 (52.79%) of them had a vitamin D deficiency and 85 (47.22%) of them had normal level of vitamin D. The lowest level of vitamin D in studied women was 21.4 ng/ml and the highest level of that was 43.80 ng/ml. There was no significant difference observed between vitamin D condition and indices of age, education background, birthplace, job, physical exercise and income. Also, there was no significant difference found between vitamin D condition and weight, height and body mass index. In conclusion according to the findings, more than half of the infertile women had a vitamin deficiency and this could be considered as a problem for their fertility health and the deficiency is not due to the individuals’ socioeconomic situation. Hence, focusing on preventive measures and early treatment seems to be of significance. Keywords: vitamin D, infertility, demographic characteristics. INTRODUCTION: Infertility is one of the most common problems among human societies and according to the estimations of World Health Organization, 60-80 million couples are suffering from this problem, worldwide [1]. There has been many reasons mentioned for infertility in women and micronutrient deficiencies are reported to be among these factors. In some studies, a negative relation between vitamin D level and success in fertility has been reported. Vitamin D is one of the fat-soluble vitamins which was discovered in 1930 and named calciferol [2]. Factors such as age, skin pigmentation, obesity, physical activity, seasonal changes, sunlight and receiving nutrients could impact the blood vitamin D level. Skin pigmentation impacts the vitamin D level [3]. Vitamin D deficiency is described as the cause of metabolic bone diseases such as rickets, osteomalacia, osteoporosis and finally weakness and loss of muscle mass, but recent information has revealed the impact of this vitamin deficiency in decreased immune system, especially forming pneumonia in children, decrease in fertility, increase in age at menarche, decrease in insulin response to glucose, decrease in cardiac contractility, hypertension and infertility [4]. The major part of the vitamin D is transformed to skin due to the UV radiation. Vitamin D is found in foods such as fatty fish species and egg. Moderate amount of vitamin D is derived from food resources such as fatty fish species or supplements [4]. High prevalence of vitamin D deficiency is among the main health issues in today’s world.
