Obesity is linked to decreased testosterone and increased estrogen levels.

Insulin Resistance

Chronic Inflammation

Inflammation affects blood vessels and erectile function over time.

Symptoms often develop gradually.

  • Weak or soft erections

These symptoms may worsen with increasing weight.
