The chance of a successful IUI procedure resulting in pregnancy will always depend on the fertility factors surrounding each individual patient. However, we have found that IUI yields about a 5-10% pregnancy rate per cycle in couples, whereas the monthly conception rate without treatment might only be 1-3%. In conjunction with gonadotropin (an injectable hormone), IUI yields a 15-20% success rate.
While this “low tech” approach can prove successful, success rates in general are often higher with a “high tech” approach like in vitro fertilization (IVF), which bypasses many of the hurdles to fertilization. If you do not achieve pregnancy after 3-6 cycles of IUI, your doctor will likely discuss moving forward with IVF treatment.
