I am very sorry to hear that. Sending you :grouphug:
My husband also has azoospermia. Although we did not do the mTese, we did not do any exploratory surgery to find any sperm. RE said he had a pretty slim chance in even finding sperm and our insurance would not cover something like that. We choose donor sperm.
I was reading your signature and it looks like you went with the best doctor (Dr. Schlegal) there is for this kind of stuff. Many ladies in the azoospermia board have said that he is the best in the business and world reknowned for azoospermia. Unfortunately, I haven’t heard of anything else that will help out.
I know it is very hard. I have been in your shoes. For me, it was just something I had to come to terms with and let go of that fact that I would never have my husband’s biological child. Even now, that we have our 14 month old son, I still wonder about getting pregnant from my husband. I don’t use birth control and so I still wonder , what if, it could still happen. I still hold out hope, but I doubt it.
Since it is still so early for you and DH on what to do next, keep in mind there are many other options out there for you. We realized in the end, we wanted a child, no matter what. We went with donor sperm. This option is not for everyone and it a decision only you and your DH can make. There is also donor embryos, adoption. I wish you all the best!
