MsRipple!
I am sorry that you are facing this diagnosis. It is devastating ... but not hopeless!
One thing that our fertility clinic did, after his diagnoses of Azoospermia, was to test again - normally, and then another one separately, giving him some medication to widen the vessels, to see if then there were more sperm (there weren't). Then he was sent to a urologist, who also did a few tests. DH's results ranged from 0 - 250k, those that were there were either abnormal or not moving.
The urologist wanted to try something before moving onto TESE (where he said the results could be could or not, since sometimes DH was producing and other times not - and he had ruled out obstructive Azoospermia). He had to take Tamoxifen for 6 weeks. We actually had really good results (8 MIO sperm) and were able to freeze 6 vials of sperm.
When we moved forward with IVF, they managed to get a few sperm each time from fresh samples, so they didn't use the frozen samples ... but no luck. For the last try (ICSI # 6, transfer #9), we tried TESE ... I was all prepped for my egg retrieval, when they told me that the TESE sample was useless, so they would be thawing 3 straws from the frozen sperm (from 2 years before)... it brought us our miracle!!
If you want to read more details of our journey, feel free to take a peek at my pregnancy journal (the first two posts describe it all in detail).
Wishing you the best of luck and much much strength on this rocky journey. It is so very hard, but you do have options. And allow the emotions to happen - I still grieve for not being able to get pregnant naturally and not being able to give our little miracle a sibling - because I just can't go through it all again! It breaks my heart every time I hear of others being successful and being able to have another child. I loved pregnancy. I loved childbirth ... it is hard
