IuI with endometriosis

Hey guys! I recently signed up to participate in a research study for women with infertility, where I will have an opportunity to 3 cycles of iui with ovarian stimulation, all at no cost. I am really excited to participate, do any of you ladies out there have endo? Have you tried iui? Was it successful? I really would like to know what you're experiences are before I get into it. Answers please!!
