How to improve Low Sperm Motility?

Today DH and I went to RE and mostly all tests were good; however, we were told that his sperm motility is a little  low. Does anyone know what we can do improve it? Any ideas and suggestions are greatly appreciated! Thanks!

I've heard that extra zinc in the mans diet really helps sperm. Not sure about motility wise but I know I've read and heard that before!

The fertility books in my little library point to Vitamin C as a key nutrient to sperm motility.  There's the obvious pill supplement he can take, but there's plenty of veggies and fruits to meet the daily needs.  Vitamin A is another good nutrient for motility, too.

I read about garlic and korean ginseng being good for sperm production and motility.
