I am on cycle just now and suffer from Atrophy, am trying Naltrexone rather than HCG to see what the effect will be on PCT.

Stopped taking the Naltrexone for a few days last week and sure enough my nuts shrunk well down, got them more or less back to full size after three days back on Naltrexone.

How do you explain changing testicular size in a vasectomised male?

Great read though!
My understanding is that having your vasa deferentia severed only prevents you from expelling sperm but does not effect your ability to get shutdown due to exogenous testosterone. The negative feedback loop is still in effect.

"After vasectomy, the testes remain in the scrotum where Leydig cells continue to produce testosterone and other male hormones that continue to be secreted into the blood stream."

And the naltrexone allows pulses of GnRH to occur as if no steroid hormones are present thus preventing spermogenise shutdown. In doing so allowing you to maintain full size of your nutz.
