Prostatitis, Prostate Cancer, and What Actually Affects Erectile Function

Three common claims about the prostate are wrong. Let's address the mechanism before discussing disease.

What the Prostate Actually Does

The prostate gland produces approximately 80-90% of the fluid volume of semen. Its main function is to liquefy seminal fluid at ejaculation. Prostate problems are common because the conditions for stagnation build easily in sedentary men.

How Prostatitis Develops

The core mechanism: pelvic stagnation.

The prostate produces a protein-rich secretion. If the prostate isn't emptied regularly and blood circulation in the pelvic region is poor, bacteria find an ideal nutrient-rich environment to settle and colonize. Bacteria available in the normal microbiome (staphylococcus, gut flora that shouldn't be in the pelvis) are sufficient — STIs are not the primary cause.

Once bacteria establish in protein-rich, low-flow conditions, chronic inflammation follows. Long-term unchecked prostatitis = chronic inflammation = elevated cancer risk.

For prevention: regular ejaculation helps, but masturbation alone is not enough. It empties the gland but doesn't eliminate pelvic stagnation. Reciprocating movement — cycling, horseback riding, sex, swimming — addresses the circulation component. If your lifestyle is sedentary (office work, extended driving), the pelvic region develops the conditions for prostatitis without these movement-based interventions.

Why Prostatitis Does Not Cause Impotence

The mechanism of erection:

• 1. Brain sends arousal signal
• 2. Endothelium of blood vessels near the penis secretes nitric oxide (stimulated by testosterone from Leydig cells)
• 3. Nitric oxide activates guanylate cyclase, producing cyclic GMP (cGMP)
• 4. cGMP relaxes smooth muscle in the corpus cavernosum (the spongy tissue of the penis)
• 5. The corpus cavernosum fills with blood → erection

The prostate is not in this sequence. It has no biochemical role in erection. The claim that prostatitis causes impotence is not supported by the mechanism.

What can happen: during ejaculation, blocked ducts from prostatitis can cause pain. That pain may produce a conditioned anxiety response that inhibits arousal. But this is psychological, not biochemical.

Prostate Cancer: What Actually Matters

What promotes it: hereditary poor anti-tumor immunity is the primary factor. Chronic prostatitis creates the inflammatory environment that raises cancer risk. Low testosterone — not high testosterone — is associated with development of prostate cancer. (Once cancer is established, cancer cells require testosterone to divide — but this is a different claim from "testosterone causes cancer.")

PSA monitoring: Prostate-Specific Antigen (PSA) is not an oncological marker — it is a surveillance marker. A single PSA test has no demonstrated impact on prostate cancer mortality (established in a 10-year study involving 500,000+ participants). What matters is tracking PSA dynamics over time.

Practice:

• Men over 40-45: test PSA every 6 months
• Track the trend, not absolute values
• PSA below 4 is generally considered acceptable
• Note: prostate massage, cycling, and sex can temporarily elevate PSA — test under neutral conditions
• A slow, gradual increase over years (1.5 → 2.2 → 3.1 → 4.2) warrants investigation. A stable value that stays in a range does not
