This article examines the crucial function of vitamin D in numerous physiological processes, particularly in reproductive health, due to the extensive distribution of its receptors in reproductive tissues. Recent research has examined the correlation between vitamin D levels and in vitro fertilization (IVF) success; nevertheless, the results are inconclusive. This meta-analysis seeks to evaluate the impact of vitamin D levels on IVF outcomes, specifically targeting clinical pregnancy rates. A comprehensive database search, encompassing PubMed, EMBASE, and Cochrane Library, revealed research from 2020 to 2024 investigating the correlation between serum or follicular fluid vitamin D levels and IVF success. Seven studies that fulfilled the requirements were examined, with results presented as relative risks and confidence intervals. Results indicate no statistically significant relationship between vitamin D deficiency and IVF outcomes; nevertheless, a non-significant trend implies that deficiency may be associated with reduced pregnancy rates. This analysis underscores the necessity for standardized, randomized studies to better explore the impact of vitamin D in assisted reproduction and offers insights for optimizing fertility care in our nation.
