Does Maternal Vitamin D Level Affect the Ovarian Reserve of Female Newborn Infants?

Abstract

Objective To evaluate whether maternal vitamin D levels affect cord blood Anti Müllerian Hormone (AMH) levels, reflecting ovarian reserve, in female offspring. Methods Cord blood AMH from healthy pregnant women delivering term female infants were compared in groups with different maternal vitamin D levels. Results Maternal age, weight gain during pregnancy, usage of vitamin D supplements, newborn birth weight, and 5th-min Apgar scores were significantly higher in the normal vitamin D level group (All p < 0.05). AMH levels were similar among all groups (p = 0.6). There was no significant correlation between newborn AMH and maternal vitamin D levels (rho = 0.006, p = 0.9). The stepwise regression analysis showed that the maternal age and birth weight had lower AMH levels, whereas the maternal vitamin D level did not. (p = 0.03, p = 0.04, p = 0.5, respectively). Conclusion Maternal vitamin D levels did not have a significant effect on AMH, a reflection of ovarian reserve.
