I can't say my husband has tried EVERYTHING to improve his sperm quality but we definitely have tried and its stayed exactly the same!!! He was on menivet, we tried a powder drink called sperm max from the health food shop. Dh very rarely drinks (maybe 4 beers a month if that!). He Does not do any form of drugs and does not smoke. And he isn't the skinniest but he isn't over weight. My husbands sperm has remained at 0% motility. low sperm count and lots of abnormal sperm for 4 years so I am sceptical abut it improving. Good luck with your journey
