I have scoured the online community for an answer but am yet to find if it exists here.
I had RP in 2014, my post RP PSA lingered at 0.1 for a few months but then rose and when it got to 0.24 I was offered salvage external RT. This took place in 2016. Thereafter, the result was a satisfactory 0.1 but last October it had risen to 0.2. My oncologist says it could be a mere test variation or indicative of recurrence. Equally, it could indicate urinary tract infection. My next blood test will soon show if this was a one-off or something more worrisome.
My reason for posting is to ask f anyone knows whether post RP sexual activity resulting in dry orgasms can raise PSA as pre-treatment sexual activity is claimed also to do? I am minded to avoid such activity until after the test but it would be helpful to know if there has been any published research on this subject.
