How do you introduce a female into a home with an adult male who is a little territorial?

I just adopted a female rottweiler, approximately 1 year from the pound the day before getting put to sleep. She is loving, gentle and responds to some commands. I arranged for my boyfriend to bring my male rott, 2 years to the park to meet her. Both dogs were on leashes with pinch collars. They were equally aggressive, with my male dog more out of control than I had anticipated. He has gone through 2 obedience courses. He has been the only Housedog for the past 3 months. He was raised from 10weeks with a female alpha rott, who regretfully was killed by a car in sept 98. Anyway, the dogs were taken to my home and separated after a few hours of a shaky introduction. The female does wiggle her tail while getting closer, but turns aggressive when he does. It is still the first night of meeting as I write to you. I need some help figuring tactics to introduce them. They currently are in separate areas of the house. I am willing to muzzle them both, but am fearful of allowing them to be off leash in the same proximity of each other.
