Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to determine whether there is a correlation between the levels of Vitamin E in sperm and sperm DNA fragmentation. Previous research has shown that damage to the DNA in sperm may cause infertility or increase the chances of miscarriage, if the damage is extensive (eg. present in the overwhelming majority of sperm). Some studies suggest that DNA damage can be caused by oxidative stress. Antioxidants, such as Vitamin E, which are present in some foods, can prevent damage to cells from "free radicals", which are naturally present by-products of metabolism. We ask whether there is a correlation between sperm DNA damage and Vitamin E
