The authors' aim in this study was to determine the vitamin D levels of Turkish women who were undergoing in vitro fertilization (IVF). The study design was a descriptive cohort study of a total of 208 infertile women at an IVF center in Turkey. Our findings showed that 4.3% of the women had a replete vitamin D level, 23.6% of the women had insufficient vitamin D levels, and 72.1% of women had deficient vitamin D levels. Our findings suggest that much more effective vitamin D support programs should be implemented for women who are seeking to become pregnant.
