Multiples are usually a result of fertility medications which are sometimes combined with IUI. You can do IUI with or without medications. Most people opt for the combo of meds + iui to increase your chances for successful conception. Talk to your dr. about what would be the best protocol for your specific situation. Good Luck
I've read ALOT of success stories with IUIs. I have heard that it can take about 3 times for it to work. I just did my first IUI and I got a BFN today. Multiples are a possability with any fertility treatment. About multiples Jon and Kate Plus 8 did IUI. Multiples are definatly a risk. I'm hoping for better luck next time. Good luck to you... I hope you get your BFP soon
