TTC: Hypospadias

I am 29 and my bf is 25. I've had Type 1 Diabetes since the age of 10. I currently have two healthy boys ages 9 and 6 born through c-sections. Three years ago was diagnosed with chronic hypertension, gastroparesis, and peripheral neuropathy. I divorced the father of my two boys and would like to start a family with my new bf as he has no biological children yet. We have been TTC for about 3 months now and no luck. Went to my ob/gyn and he told me that everything was fine on my end. My bf however was born with hypospadias and I am starting to believe that is why I am not getting pregnant. Has anyone ever heard of this or run into any trouble?
