My DH also has
male factor issues with a very low morphology (1%), borderline motility
and a count that seems to fluctuate from good to poor.
I have him taking a ton of vitamins, minerals and herbs, including B, C, D, E, folic acid, l-carnitine, l-glutamine, zinc, selenium, coenzyme Q10, lycopene, a multi-vitamin and maritime pine bark (an antioxidant).
