Lucie - some doctors are just ridiculous when it comes to thinking of other peoples feelings, they always tell me I'm obese or too overweight I'm a very mean way. On the other hand it's fantastic that he wants to get it sorted from my own and my friends experiences specialists always actually do something about it. Which of course is wonderful. I googled the thing your hubby might have and it doesn't sound too bad, I mean it can be fixed!! If that's what it is. Also it will be nice to have an answer, I really feel for all the people with unexplained infertility, could you imagine being told in the end that there is no reason. I hope you have an answer and get to making that baby.
Love
