Is it true that older men produce more daughters?

I've been reading articles online and they say that older men are more likely to produce girls. My husband will be 35 in February and we just found out that we are having a girl. Does this really mean that we won't ever have a boy due to his age? (I'm 28 btw). Anyone have a husband around or over age 35 and have a boy? I'm hoping the study on this isn't completely true because I'd like to have a boy eventually.
