@dr.t__np's PSA claims for TRT patients, fact-checked

What did @dr.t__np actually say?

The creator, presenting as a nurse practitioner running a TRT clinic, made several specific claims about PSA elevation: that high PSA "doesn't mean cancer" and is "99% of the time" benign, that MRI is "97-98% effective" and is the gold standard over biopsy, that biopsies are only "about 47% accurate," and that common activities like riding a motorcycle or sexual activity can spike PSA. They also said prostatitis and BPH are the usual culprits in older men on TRT.

These claims are a mix of genuinely good reassurance and some numbers that deserve scrutiny. The overall message, that a single elevated PSA is not a death sentence, is clinically reasonable. But the specific percentages the creator throws out are either unsourced or oversimplified in ways that could mislead patients.

Does the science back this up?

Partially, yes. The American Urological Association (AUA) does recommend multiparametric MRI (mpMRI) as a preferred diagnostic step before biopsy in many clinical scenarios, particularly for men with elevated PSA but no prior biopsy. The PRECISION trial (Kasivisvanathan et al., 2018, NEJM) found MRI-targeted biopsy detected more clinically significant cancers and fewer insignificant ones compared to standard biopsy. That is a real result.

But "97-98% effective" is not a number you will find cleanly attributed to prostate MRI in any landmark trial. MRI sensitivity for clinically significant prostate cancer is typically cited between 74-93% depending on the study and cancer grade (Weinreb et al., 2016, European Urology). The 47% biopsy accuracy figure also needs context. Standard 12-core systematic biopsy does have real limitations, but accuracy varies considerably based on PSA level, prostate volume, and cancer grade. Calling it flatly 47% accurate strips all that nuance away.

What did they get wrong (or right)?

Credit where it is due: the creator is right that a single high PSA should not trigger immediate panic or biopsy. Repeat testing after eliminating confounders, like sexual activity, vigorous exercise, or recent prostate manipulation, is standard practice. The AUA and the National Comprehensive Cancer Network (NCCN) both support this approach. The creator is also correct that prostatitis and BPH are common, often reversible causes of PSA elevation in men on TRT.

Where they went wrong is with the "99%" framing. PSA is a real cancer screening tool, and dismissing it that broadly is a problem. Among men with PSA between 4-10 ng/mL, approximately 25% will have prostate cancer on biopsy (Catalona et al., 1994, JAMA). That is not a trivial number to round down to 1%. The creator also describes BPH as "benign prosthetic hypertrophy," which is an error. The correct term is benign prostatic hyperplasia. A small slip, but worth noting in a video watched 42,000 times by men making decisions about their health.

What should you actually know?

PSA is not a binary cancer alarm, but it is not meaningless noise either. Elevated PSA in men on TRT deserves a systematic workup, not dismissal. Testosterone therapy itself does not appear to significantly raise PSA in most men with normal baseline levels, a finding supported by the TRAVERSE trial (Lincoff et al., 2023, NEJM), but men on TRT should still have baseline PSA checked before starting and monitored regularly.

If your PSA comes back elevated, your provider should first rule out confounders and repeat the test. If it stays elevated, referral to urology and consideration of mpMRI is appropriate per AUA 2023 guidelines. Biopsy is not automatically the next step, but it is also not as inaccurate as this video implies. Your urologist will factor in your PSA density, free-to-total PSA ratio, and MRI findings before recommending anything invasive. No TikTok, including this one, replaces that conversation.
