There are lots of things that can be done to increase the numbers and motility of sperm. Lulu is spot-on with the Zinc, Vitamin E and C are also really important, as are Omega 3 oils. It takes 116 days to make entirely new sperm, so don't despair - get hubby onto some supplements, and have another test done in around 3 months time. I have often seen sperm counts double, and motility increase dramatically from just using the nutrients listed above - all the best to you two xxx
