The Effect of Vitamin D on in Vitro Fertilization Outcome

Status Completed

Clinical Trial Summary

To date, several studies have been done to explore the relationship between Vitamin D level and IVF outcome; however, the results are controversial. Sample sizes in these studies mentioned above were relatively small. In addition, there are no prospective cohort studies in this field. Thus, here the investigators carry this prospective observational cohort study to demonstrate the relationship between vitamin D level and IVF outcome.

Clinical Trial Description

Vitamin D level is measured before the commence of IVF cycle. According to Vitamin D level, patients are divided into 3 groups: A, Deficient, <20 ng/mL; B, Insufficient, 20-29.9 ng/mL; C, Replete, >30 ng/mL. Ongoing pregnancy rate are compared among these three groups after controlling age, number of embryos transferred, ect. In addition, Vitamin D level is also meassured before embryo transfer in FET cycles with PGT treatment. The effect of Vitamin D on IVF outcome is detected in patients transferred with Euploid embryos. ;
