I suppose I could read the full report if I cared enough to, but I've already refuted Stogi's poorly thought post and I really don't care if his balls rot off. 
Well first of all, you can't believe everything you read. Secondly, Marijuana has been known to decrease the sperm count for a long time, but why is it only now that it has become a "health" factor? Thirdly, those that use marijuana are way more likely to use other drugs which the article does not address. And lastly, the way ANY marijuana experiment is held except those that set and supply predetermined amounts of the drug will always be defective at the core. So like I said before, this article isn't scientific relevant,, it's merely a survey.
So ya....try and be a bigger dick...
