Hello, I understand your feeling and you enthusiasm to know. There might be two possible reasons Let's put it in your understanding way. Let us take a computer as a example and let us compare your uterus, ovaries, tubes as the hardware of the computer if every gross thing is fine with the hardware then there should be a problem with the software. Here the softwares are hormones which are main reason for fertility you need to check in for that. If that is not the case then the failures of iui might be the centers error. Please cross check. Thank you
