To study the vitamin D levels in infertile females and correlation of Vitamin D deficiency with AMH levels in comparison to fertile females

Abstract

Context: Human and animal data suggest that low vitamin D (25-hydroxyvitamin D) status is associated with impaired fertility, endometriosis, and polycystic ovary syndrome. Vitamin D regulates antimullerian hormone (AMH), FSH, mRNA, and expression of genes in reproductive tissues, implicating a role in female reproduction. Aims: To study the vitamin D levels in infertile females and to know the correlation of vitamin D deficiency (VDD) with serum AMH in infertile females compare to fertile females. Settings And Design: This prospective study was conducted in department of Maternal and Reproductive Health in between April 2014 and April 2016. Materials and Methods: After matching inclusion and exclusion criteria out of total 70 infertile females, 45 were found to have VDD. Of these 35 patients were identified as cases; in whom, the AMH levels were assessed. As control 35 fertile normal females were taken, in which vitamin D and AMH were taken. In both groups, correlation of VDD with AMH was studied. Statistical Analysis Used: To analyze the correlation between vitamin D and AMH linear regression test and for comparison of both the groups, two sample t tests were used. Results: The VDD was present in 64.28% of infertile females. In vitamin D deficient cases, the mean for vitamin D was 6.18 ± 2.09 and AMH was 1.94 ± 1.30. In vitamin D deficient controls, the mean for vitamin D was 4.85 ± 3.02 and AMH was 3.47 ± 2.59. On comparison, the vitamin D levels were lower in fertile than infertile females, which was significant (P = 0.04), and AMH levels were lower in cases than control group (P = 0.003). Conclusion: The VDD was present in 64.28% of infertile females. No significant correlation was found in between VDD and AMH levels in both the groups.
