2nd sperm test confirmed ZERO

My husband got his results back from his second sperm test. It was confirmed ZERO again. He also got hormonal bloodwork back and everything looked good except testosterone was a little low. The doctor said that shouldn’t be causing a zero.

Now we just have to wait back on genetic testing to see if he’s just not producting any sperm at all. If all that checks out then he will have to do a biopsy to see if there is a blockage.

This is all just very overwhelming for us. We are trying to prepare ourselves for all options. Does anyone have any advice or words of wisdom?
