Sorry, but tamsulosin won't reduce prostate size. It's an alpha-blocker, which relaxes smooth muscle of the internal urinary sphincter and the prostate itself. So it has a similar effect to the TURP, but there may come a point when you need more than tamsulosin can do (or in a few cases, if you can't handle alpha-blockers, or don't want to take them), and then the TURP will be needed.
There are hormone therapy drugs to reduce prostate size, finasteride and dutasteride. They are dihydrotestosterone synthesis inhibitors (sometimes called 5𝞪-reductase inhibitors, as 5𝞪-reductase converts testosterone to dihydrotestosterone). They have some of the same side effects as the prostate cancer hormone therapy drugs, but they don't remove testosterone, so not so drastic. Removal of dihydrotestosterone will result in a significant (but not full) shut down of prostate and seminal vesicle function, loss of body hair on arms, pits, legs, chest, conversely a reversal of baldness, and significant reduction of libido but not to the same extent as prostate cancer hormone therapy drugs which also remove testosterone.
One big warning with finasteride and dutasteride is they halve your PSA readings, so you must remember to double all your PSA readings when on these for the purpose of assessing prostate cancer risk.
One thing that's a bit strange about your situation is that if you are short of testosterone, BPH is quite unlikely, but it may be that your TRT has kept you with normal or even higher than normal levels, in which case BPH is a possibility.
