I am not aware of a relationship between high testosterone and high PSAs, although testosterone can add fuel to existing PCa.
Keep in mind that many young men have very high testosterone levels and very low PSAs.
Just my opinion, of course, but I would suggest that you have another PSA done much sooner than 6 months out...perhaps 1 to 2 months from when the most recent one was done.
MOST prostate cancers are slow growing....but NOT all of them....so I would err on the side of caution.
Just my two cents, for what it is worth.
