TRT can readily play into a PSA reading, TRT also tends to increase BPH which increases PSA, sex within 48 hours of test, various factors along with the phase of the moon and how you were holding your mouth when they drew the blood (ok, just kidding with those two) can affect PSA. I have read that prostatitis is notoriously difficult to diagnos and cure.
Things to look at before you go the biopsy route, probably better to get a PHI test, and possibly a PCA 3 test.
More reliable results than a simple PSA. However, you need to understand there is no definitive diagnosis for prostate cancer other than positive biopsy. Negative (blind, not targeted) biopsy is not necessarily definitive.
Suggest if you need more testing you obtain PHI, PCA3 and then if you need more diagnostics move on to 3T multiparametric MRI with Diffusion Weighted Imaging and a PIRADS score. This MRI can be then used (if something found to target) for a Targeted MRI or Fusion Biopsy.
