From: Effects of alcohol use on sperm chromatin structure, a retrospective analysis
Breaks the alcohol consumption of 209 human male infertility subjects into four categories: none (0 drinks/week), rare (0.5- < 3 drinks/week), moderate (3.5–10 drinks/week), and heavy (> 10 drinks/week). The bars on the left denote the average %HDS (High DNA Stainability) of the men in each category and the bars on the right denote the average Total DFI (DNA Fragmentation Index) of the men in each category on a sperm chromatin analysis test
