How can you address low sperm motility?

You can't (mostly): Most experts say you can't. Even if low you don't need to boost motility already in a normal range. Common sense like reduced alcohol and no tobacco helps some men, but it's a very small change. Men with anatomic abnormalities sometimes improve mot through surgery. Some fertility specialists and uroplogists have good experiences with using supplements and drugs, but no good studies back this up.
