Why this publication exists

Prostate supplement marketing often moves faster than the evidence. Prostate Pathways is designed as an independent editorial bridge: understand the symptom or ingredient first, inspect the evidence, then make a purchasing decision only if it still makes sense.

For example, BPH is a noncancerous enlargement of the prostate and can cause weak stream, urgency, frequency, nocturia and trouble emptying the bladder. Those symptoms can also have other causes. NIDDK explains BPH and its treatment options.
