I have had a raised PSA for 14 years, it fluctuates so it doesn't always go up. I have had 2 biopsies one of these taking 28 samples, both were negative, I have also had 3 scans, 2 of these being mpMRI scans, also showing nothing. I was put back on Finasteride to help reduce enlargement again, I have been on it for a year but this time it has only dropped to 5.88, which of course is not a true reading because I'm on Finasteride, although flow is vastly improved, so that's my story. My question is, can high levels of testosterone (a very high sex drive) lead to an increase in PSA? this is the only question I can't get an answer to, any help gratefully appreciated.
