RESUMEN
Background: Recent studies have shown that vitamin D has an essential role in the reproductive system. In this study, we aimed to investigate the effect of vitamin D levels in patients undergoing ovulation induction [OI], and subsequent intrauterine insemination [IUI] procedure
Materials and Methods: One hundred and four infertile and one hundred and three fertile women were recruited in this cross-sectional study which was conducted in a tertiary level maternity hospital. Infertile patients were divided into pregnant and non-pregnant subgroups after treatment. Individual characteristics and 25-hydroxyvitamin D3[25 [OH] D3] levels were compared between the groups
Results: The vast majority of our study population consisted of women who had vitamin D deficiency [96.6%]. There was no statistically significant difference between infertile and fertile groups in terms of serum 25 [OH] D3 levels [P=0.512]. Similarly, no significant difference was observed between the pregnant and non-pregnant subgroups of infertile patients regarding 25 [OH] D3levels [P=0.267]
Conclusion: There is no association between female infertility and serum vitamin D levels. Vitamin D does not predict pregnancy in infertile women undergoing OI with IUI. Further research which will provide a comparison between much more women who have deficient and sufficient 25 [OH] D3levels is warranted
