NCT03829943

Brief Summary

The purpose of this study will be to investigate if there is a correlation between Vitamin D levels and Sperm DNA Fragmentation. This is a prospective, cohort study. In this study male participants presenting with their partners because of inability to conceive will be recruited for this study. Participants will have a blood sample drawn which will be tested for Vitamin D level. The investigators will then compare sperm DNA fragmentation between normal Vitamin D levels, Vitamin D insufficiency, and Vitamin D deficiency. All infertile males who present to the investigators' infertility clinic have a Semen analysis and Sperm chromatin Structure Assay (SCSA). The research part of the study will be to obtain the Vitamin D level.
