I'm pretty sure they are. Imperium of man can count on trillions of fertile people willing to have children. Astartes simply don't need to fill that role. I can't even imagine how they could handle that...situations were they could knew women, have a relationship, spending time with them. More, looking at their task, having children could be a very dangerous lever for Chaos to push on.

I really hope they are sterile. Last thing we need is a sort of soap-opera novel talking about Astartes and theyr family/love issues.

C'mon, this is simply a non-exixtant issue. They are the cosen to protect their kind and the living weapon of the Emperor: not even the thought of sex/children is something that could trouble their mind even for a second.
