Study out today indicates ibuprofen even at a fairly low regular use may harm male fertillity. Six ibuprofen tablets can affect men's fertility libido | Daily Mail Online

I would have hubby drop ibuprofen immediately for if he takes it regularly (if he can get by without it, that is.)

Also, ladies, use ibuprofen sparingly if you can. We don't know what the effects of it are.

And please check out the little box at the end of the article - taking paracetemol/acetomenophen, aka Tylenol, during pregnancy may harm your baby's ovaries and testicles (this is less cut and dry than the ibuprofen but since paracetemol/acetomenophen are oft-touted as totally safe during pregnancy you may want to cut back on it if possible.)
