Hi Liz,
Any ‘tweaking’ of the prostate or other stimulation such as ejaculation, DRE, prostate G-spot milking, anal sex, biopsies, etc, etc,, inevitably increase PSA levels, albeit temporarily.
Personally, if I was your old feller, I would hang out for a template biopsy rather than a TRUS.
If you like, read my other posts on this subject.
No doubt Matron will admonish me for advocating wasting our NHS hundreds of thousands of pounds, but where is the economy of a TRUS biopsy, having to be followed by a template biopsy shortly afterwards?
Hope it turns out OK for you both.
Cheers, John
