Retrograde Ejaculation, Sudafed, and Waiting

We had our follow up with our fertility clinic yesterday.

We got good news, bad news, and a “You should wait.”

We’ve been TTC for 24 cycles now. DH doesn’t ejaculate during oral, and I suggested to him about 18 months ago that I believed RE was the cause. At this time, I had suggested the Sudafed regimen. He had done it one cycle and told me it was crazy.

Doctor’s tests confirm not only the RE but that the Sudafed regimen is working. So, the bad news is that he is ejaculating into his bladder.

The good news is that he was able to produce an “antegrade” (not in the bladder) sample and that sample was straight up amazing.

0.6 mL sample with over 100M healthy mobile sperm.

However, the doc doesn’t have a way to increase his ejaculate volume.

Given these results, the doc says we should try the Sudafed regimen for 6 more months and then look into other options like IUI.

And though I should be grateful that he thinks we can get pregnant on our own, part of me is just tired of waiting. Can anyone else tell me their experience with this? Any suggestions to boost semen production (not sperm health)?
