25-Hydroxyvitamin D (25(OH)D) and biomarkers of ovarian reserve

Objective: The aim of the study was to examine the associations between 25-hydroxyvitamin D (25(OH)D) and biomarkers of ovarian reserve in a large community-based sample of women. Methods: In 2010 to 2016, women aged 30 to 44 years without any known fertility problems were recruited from the Chapel Hill, NC area for a prospective time-to-pregnancy cohort study. At enrollment 561 women provided a blood sample that was used to measure 25(OH)D, anti-Müllerian hormone (AMH), follicle-stimulating hormone, and inhibin-B. Unadjusted associations were estimated with Spearman correlation coefficients. Multivariable linear regression was used to estimate associations of 25(OH)D with ovarian reserve biomarkers, after adjusting for age, race, body mass index, smoking history, and recent use of hormonal birth control. Results: The mean 25(OH)D was 36 ng/mL (SD = 11 ng/mL). 25(OH)D was not correlated with AMH, follicle-stimulating hormone, or inhibin-B (all r
