Low successful pregnancy and live birth rates even after successful ovulation induction (OI) and\n in vitro<\/jats:italic>\n fertilization (IVF) in these patients indicate that endometrial dysfunction may be another important factor contributing to infertility. Vitamin D acting through nuclear receptors induces the expression of various genes required for cell growth and differentiation and plays a crucial role in reproduction. Homeobox 10 (HOXA10) may be one of the potential targets for vitamin D action. HOXA10 gene product promotes the differentiation of endometrial cells, making the endometrium receptive for implantation. The present study was undertaken to determine the effect of circulating vitamin D levels on HOXA10 gene expression in endometrial tissues and its possible influence on the reproductive outcome of PCOS patients undergoing OI procedure.\n <\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n \n A prospective cohort study was conducted on 110 infertile PCOS patients. The patients were divided into two groups: Group 1: Vitamin D \u00b320 ng\/ml, Group 2: Vitamin D <20 ng\/ml. Endometrial samples were obtained from 22 patients using pipelle biopsy, used to determine HOXA10 mRNA (messenger ribonucleic acid) expression by quantitative RT-PCR (reverse transcription-polymerase chain reaction) and protein expression by Western blotting. OI was performed using Clomiphene citrate or Letrozole from the 3\n rd<\/jats:sup>\n day of the cycle, and patients were followed up for a maximum of five cycles. Attainment of successful pregnancy was considered a positive outcome.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Both the groups were similar in mean age and other endocrine parameters. Serum vitamin D levels were significantly low (\n P<\/jats:italic>\n < 0.001), and BMI (body mass index) was significantly high (\n P<\/jats:italic>\n = 0.032) in group 2 compared to group 1. Endometrial HOXA10 mRNA (by quantitative rtPCR) and protein expression (by western blotting) were significantly low in group 2 compared to group 1. The clinical pregnancy rate was low in group 2 (\n 28.6%)<\/jats:italic>\n compared to group 1 (\n 42.3%)<\/jats:italic>\n , but this difference was not significant (\n P<\/jats:italic>\n = 0.22). On regression analysis adjusted for age and BMI, vitamin D was an independent predictor of successful pregnancy after OI (\n P<\/jats:italic>\n = 0.09).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Circulating vitamin D levels influence the endometrial HOXA10 gene expression, and this may be reflected on the reproductive outcome of infertile PCOS patients undergoing OI.<\/jats:p>\n
