Iui Chances Of Twins. I think that the chances of getting pregnant from IUI are pretty slim no matter what but before you do one with that many follicles I would think long and hard about whether you are willing to do a selective reduction. Fraternal twins occurs when two different eggs are fertilized by two different. Mothers of twins and higher order multiples are more likely to experience high blood pressure and preeclampsia which can lead to seizures gestational diabetes infection and even death. The chances of twins do not increase with iui they increase with the number.
IUI and IVF also carry different chances of fraternal or identical twins. IUI is a modest intervention with similarly modest results. It was one fertilized egg that split after conception instead of 2 fertilized eggs which is the where the increased risk of multiples and IUI comes from. In that case one in 89 couples conceive fraternal twins. This can help women or couples achieve pregnancy even when certain infertility factors exist such as low sperm count or mild endometriosis. On its own IUI does not increase the risk of twins.
If you use gonadotropins to produce multiple eggs your chance of conceiving multiples is about 30 percent.
IVF 41 in Jan 2012 converted to IUI on 1712 BFN. It was one fertilized egg that split after conception instead of 2 fertilized eggs which is the where the increased risk of multiples and IUI comes from. Eighty percent of the time the twins conceived while their mother was using Clomid were fraternal twins. IVF 41 in Jan 2012 converted to IUI on 1712 BFN. It is estimated that the risk of having twins while undergoing Clomid treatment is 10 while the risk of triplets is less than 1. I achieved a successful pregnancy.
