ADT and Testicle Size

I was on ADT from October 2016 to April 2017, first three months on Firmagon followed by 2 three month Lupron shots. My testicles shrinked considerably and testosterone was 44 in January 2018. My testicles have not returned to original size. Does it mean my testosterone is still low. If so, what does rapidly rising PSA (0.1 in January 2018, 0.2 in April 2018, and 0.9 in July 2018) imply?

This whole subject is of interest to me. Months before my one and only biopsy (which led to my diagnosis earlier this year), I had expressed concern to my urologist that my testicles both seemed notably swollen. He didn't seem the slightest bit interested or concerned at the time, and my PSA was heading up rapidly. Upon my insistence, he ordered an ultrasound of the scrotum and testicles, which came back negative, and he later stated that he felt the swelling was simply general pooling of fluids in the lower body and limbs from insufficient exercise and poor circulation. Weeks later, the biopsy led to a high risk PCa diagnosis.

Interestingly, the testicles both remained swollen until a couple of weeks into recent Casodex treatment, when the swelling seemed to dissipate considerably, and by chance, the PSA (not T), has since plummeted. Now, I'm learning here that ADT in-general is known to shrink them.

A guy hates to jump to conclusions, and maybe everyone else on earth already knew this, but there certainly does appear to be a correlation of sorts here, wherein swelling is proportional to PSA and or T levels.
