Cats require long adjustment periods - anywhere from 2 weeks to several months.  You should seperate the cats for awhile and slowly start to re-introduce them.  Do what Spencer said about getting each of their scents on a towel and then swapping towels so they can get used to smelling the other.  For instance, rub the male with a towel and then put it under the female's food bowl then do the same thing with the female.  After doing this for a little while, start feeding them on opposite sides of a door so they're eating right next to each other but there's a door in between.  Let them get used to each other's scent for a week or even two before allowing them to see each other again.  Even if it doesn't work out after that, I'd still give a longer adjustment period and see if they could work things out.
