PSA on TRT

What the number means, why it moves on a protocol, and how it sits with related markers.

What it is

Prostate specific antigen is a protein the prostate leaks into the blood. It is the screening number for prostate trouble and it rises a little on testosterone.

The range

How to read the lab range

Under 4 ng/mL is the cut-off most labs use, and under 2.5 is often quoted as comfortable. On testosterone, a rise of more than 1.4 within a year is a change commonly flagged to a urologist.

Questions people ask

Does TRT cause prostate cancer?

Current evidence says no for men screened before starting. It can make an existing cancer grow, which is why PSA is checked before and during.

Why did my PSA jump?

Cycling, sex or an infection in the two days before the draw can lift it. Any confirmed rise is one for your doctor, not something to read alone.
