Zita West Supplements?

Has anyone ever had their dh taking any Zita West supplements? My dh has low sperm count (according to the at-home tests) & I was looking online for some sperm boosting vitamins. I found the Vitamen supplement & was wondering if anyone had any successful stories from using that stuff?  http://www.zitawest.com/buy/supplements/fertility-and-conception/
