Review Articles VITAMIN D AND MALE FERTILITY

Abstract

Experimental and observational research found that males with vitamin D deficiency were likely to have testosterone deficiency or be at increased risk for it. Semen quality was also shown to be affected by low vitamin D levels, and it was the most consistent finding. It has been demonstrated that vitamin D directly affects spermatozoa and has a beneficial relationship with sperm motility. By
describing experimental and clinical investigations in animals and humans addressing the link between testis function and vitamin D, the current review summarizes current information on the role of vitamin D in male fertility.
