Episode notes
Erectile Dysfunction Is Common And Linked To Heart Health
- Erectile dysfunction is common and rising, affecting as many as 6 in 10 men over their lifetime.
- IFOP data shows prevalence increased over the last 15 years and it's often linked to cardiovascular risk factors like diabetes and high blood pressure.
How Erections Work From Brain To Blood Flow
- Erections begin in the brain with sensory and mental stimulation and cannot be controlled by willpower alone.
- Physiologically arousal relaxes penile arteries, filling the corpora cavernosa so blood is trapped and the penis expands.
Vascular Damage Directly Causes Erectile Problems
- Physical causes include damaged or narrowed penile arteries from diabetes, high blood pressure, high cholesterol, or smoking.
- The cavernous bodies need oxygen, so systemic vascular disease directly impairs erection mechanics.
