Regaining Natural T Production

[nuke2]

I've ill-advisedly engaged in TRT treatment without hcg for almost a year now. My T dose has almost doubled from my starting dose. I've also recently taken a DIY,walgreens sperm count test. It registered low. (I did forget on step in the procedure. I forgot to stir the sample. This could be a factor.)

I'm assuming the synthetic T alone has suppressed my natural T and sperm levels to very low or effectively zero.
- Is there any point in taking hcg now? I've been told the hcg could re-trigger my natural production while on synthetic T.
- Is this true?
- If I want to regain my natural production(total T:400-600), do I need to stop everything?
- If so, for how long?
- Is there anything I can do to expedite the transition or make it less painful?

Thanks!
