Infertility can be broadly categorized into explained, reasons for which vary from failure of conception due to reproductive health issues of a male or female partner.
Aims: This study aims to investigate the association between vitamin D status and clinical pregnancy rates in women undergoing ICSI.
Methodology: Study setting: Ain Shams University Maternity Hospital. Study duration: March 2016 - November 2016 Number of patients: Included 240 patients. Study Design: A prospective Cohort study. The study was registered on ClinicalTrials.gov Clinical Trials.gov identifier: NCT02987478
Results: The current study was conducted at Ain Shams University Maternity Hospital during the period between January 2016 and November 2016. A total of 240 women planned to undergo IVF/ICSI for unexplained infertility were included.
Conclusion: The current study showed a significant association between reduced serum vitamin D and lower clinical pregnancy rate after IVF/ICSI in women with unexplained infertility.
Recommendations: Clinical trials are needed to address whether vitamin D and calcium supplementation would improve clinical pregnancy outcome following IVF/ICSI in such group of women.
