Sucess with 1st IUI ??????

I am getting ready to do my 1st IUI within the next month and I was just wondering what my sucess rate would be to get pregant on my first try? I am gunna be taking gonal F and my hubby also has a low sperm count and I am just wondering if we really have a chance because we are using all the money we have saved for this procedure and if it does not work the first time we wil have to wait a whole year to save up the money again as it cost $3,000 total for one IUI cycle in AZ . So if any of you ladies can give me some good sucess stories with a !st try IUI I would really love it I need all the words of hope I can get

Thanks Jenny
