Prostate

PSA (corrected for 5-ARI)

If you are taking a 5-alpha reductase inhibitor (finasteride or dutasteride), your measured PSA is suppressed.

What it is

If you are taking a 5-alpha reductase inhibitor (finasteride or dutasteride), your measured PSA is suppressed. The corrected value estimates what your PSA would read off the medication so it can be compared against normal reference ranges.

What affects your levels

The multiplier applied depends on how long you have been on the medication: about 1.5x under 12 months, 2.0x between 12 and 24 months, 2.3x between 2 and 7 years, and 2.5x beyond 7 years. This reflects the cumulative suppression of PSA over time.

Signs and symptoms

The corrected value itself has no symptoms. It is a tool for interpretation. Any urinary or prostate-related symptoms should be discussed with your doctor.

Foods that help

Dietary choices that support prostate and metabolic health apply equally here: vegetables, legumes, whole grains, fatty fish, and cooked tomato products.

Foods to limit

Limit heavy alcohol and ultra-processed foods. The corrected value and its trend over time should be interpreted together with your doctor.
