Fertilaid with IUI cycle

I had my first IUI using Gonal-F 225 and trigger shot April 14 and IUI on April 15 and 16 and it was negative 11 post IUI. Going to try again has anyone had luck using Fertilaid or any other supplements?  My DH has low morpholog. Not sure why it failed so quickly. I have never had to deal with fertility issues when I had my 2 children in my early twenties with my first husband.
