Is this you?
- You used to wake up hard most mornings; now rarely
- It happened gradually over months or years
What the research says
Morning erections (NPT, nocturnal penile tumescence) are a marker of vascular and hormonal health. Their disappearance is clinically meaningful.
How tantra approaches this
Once medical causes are ruled out, tantric and Daoist practice can re-engage the systems that produce NPT — circulation, parasympathetic tone, libido.
When to see a doctor instead
Always — get cardiovascular and hormonal evaluation.
