In this episode of Intellectual Medicine, Dr. Stephen Petteruti challenges the common belief that a low PSA is always good news. He explains that PSA is not a cancer marker by itself, but a natural substance produced by the prostate, and that testosterone plays an important role in normal PSA production. If testosterone is low, PSA may also appear unusually low, which can create a false sense of reassurance. Dr. Stephen discusses why men, especially those over 50 or 60, should evaluate PSA in the context of hormone health, vitality, and overall risk rather than reacting to a single number. He also cautions against fear-based decisions around prostate biopsy, radiation, or surgery, arguing that men deserve a broader, more informed approach to prostate health. The episode also explores testosterone therapy, MRI before biopsy, body fat reduction, and the need for clinicians who understand both prostate cancer and whole-person men’s health.Timestamps:(00:27) Why Dr. Stephen says to avoid prostate biopsy(00:49) Can a PSA level be too low?(01:19) Why conventional prostate treatments are questioned(01:37) The connection between low testosterone and prostate cancer risk(02:27) Why PSA should be interpreted with testosterone(03:20) What happens to PSA when testosterone therapy begins(04:00) Why a low PSA may not always be reassuring(05:01) When a rising PSA may reflect hormonal balance(06:01) Why MRI should come before biopsy(06:38) Why prostate health needs a broader medical perspective(07:35) How PSA is useful but often misinterpreted(10:21) Why body fat matters for cancer risk(10:41) When low PSA should prompt a testosterone check(11:21) Why testosterone therapy should be medically guided(12:44) Final warning about low PSA and scare tactics
