OBJECTIVE: To determine whether a relationship exists between vitamin D (25OH-D) levels and ovarian reserve parameters (antimüllerian hormone [AMH] and FSH levels) in a large cohort of infertile women with a high prevalence of diminished ovarian reserve.
DESIGN: Retrospective cohort study.
SETTING: Academically affiliated private fertility center.
PATIENT(S): A total of 457 infertile women 21-50 years of age who had baseline hormone measurements.
MAIN OUTCOME MEASURE(S): Statistical analyses to determine whether a relationship exists between AMH, FSH, and serum 25OH-D levels.
RESULT(S): As defined by 25OH-D <20.0 ng/mL, 74/457 patients (16.2%) had vitamin D deficiency. AMH and FSH levels did not vary between women with vitamin D deficiency and those with normal levels (0.8 ± 3.0 vs. 0.5 ± 1.6 ng/mL [P=.18] and 9.4 ± 7.2 vs. 9.2 ± 9.5 mIU/mL [P=.54], respectively). Multivariate linear regression analysis of log-transformed AMH and FSH with 25OH-D levels adjusted for age, body mass index, and seasonal variation confirmed lack of association. Receiver operating characteristic (ROC) analysis to determine if 25OH-D levels are predictive of AMH showed areas under the ROC curves (AUCs) for women <38 years of age to be 0.501, 0.554, and 0.511 for AMH threshold values of 0.5 ng/mL, 1.0 ng/mL, and 5.0 ng/mL, respectively. For women ≥38 years respective AUC values were 0.549, 0.545, and 0.557 ng/mL.
CONCLUSION(S): Vitamin D levels were not associated with ovarian reserve in a large group of infertile women with a high prevalence of diminished ovarian reserve. Previously reported vitamin D-associated outcomes in infertility patients may, therefore, be mediated by factors other than ovarian reserve.
