Assuming eggs are released as expected but due to tubal occlusion, an ovulated egg is unable to be fertilized by sperm or to reach the endometrial cavity. If sperms do reach an egg, they may not be able to penetrate the egg’s covering. Then if an egg is fertilized, two-thirds of all human embryos fail to develop successfully.

"IUI" simply increases the chance of pregnancy, but fertilization may not occur for a variety of reasons. Tubal obstruction will prevent access of sperm to the released egg. Ask your GYN physician about a hysterosalpingogram (HSG) if pregnancy attempts continue to be negative.
