I was just sitting here wondering, my boyfriend is a type one diabetic. I am deeply in love with him and plan on spending the rest of my life with him. We had briefly discussed having children together. I was wondering is there any complications that a 30 year old man or so could have with fertility if they are diabetic? Also what are the chances of passing it on if he is the one with type one juvinille diabetes? I had read 7-10% also your experiences. I was just wondering if maybe it is a concern he doesnt express?
