OP - Back to your original question; yes, you need hCG. You don't have to take it but the downside is not good. If you've read the threads here then you know what I am talking about. hCG also back fill all three CHOL pathways which is a good thing when you are shut down.
See the link below, it's been posted here many times. It's Dr. John Crisler's white paper on the use of hCG.

Don't read it...study it.
Print it out and give it to your Physician to read and understand.
This will hopefully get you on a hCG protocol.
I see nothing in your posts about your E2 levels. Most, not all, but most men need an anti aromatase inhibitor to keep control over testosterone converting to Estradiol. Very important and let me say that one more time...very important.
