How I’m de-aging my penis

Hi Friend,

Men - if you're not having robust boners at night, you're 70% more likely to die prematurely.
If you're grinding at the expense of your health, you're flaccid.

Women - the same is true for you too. You have similar arousal cycles as men each night (your clitoris engorges). It’s how our sex organs remain in good health. Sadly there isn’t as much data on female nocturnal arousal cycles and so in this email the focus is on male sexual health. That said, the insights and recommendations are equally applicable.

How long are you erect during your sleep?
Healthy men in their 20s can experience 3+ hours of nighttime erections in 3-5 erection episodes. This drops to under 50 minutes for those 75+ [1]

Why does this matter?
❌ Men with erection problems are 70% more likely to die early compared to those without, even when other factors are considered.
❌ Problems with erections often show up 3-5 years before heart disease does [2]

How do nighttime erections affect penis health?
It's a classic case of "use it or lose it."

Think of nighttime erections as how your penis works out.
Erections keep the tissue healthy by bringing in oxygen-rich blood - the more they last, the better.
Without these regular exercises, the penis can develop scar tissue over time, making it harder to get erections.

How to improve your nighttime erections
For these nighttime erections to happen, you need:
✅ Healthy nerves
✅ Good blood flow
✅ High sleep quality
✅ Balanced hormones (especially testosterone)

If any of these are off, it can affect erections.

How I measure my penis health

Semen Analysis - regular testing to track changes in sperm count, motility, and morphology.
Measurement of Nighttime Erections - as health indicators of physiological cardiovascular and sexual vascular health.
Blood Flow Testing - using ultrasound to measure penile blood flow.
Urine Flow Tests - assess max urination speed to ensure urinary health.
Questionnaires - scoring sexual function.
Prostate Health - regularly measure prostate size.
Core Health Practices - prioritize quality sleep, balanced diet, and regular exercise.

You can measure your nighttime erections and get your AndroAge (erection health age) score using the Adam Health sensor.

My AndroAge is below 20
My nighttime erections are the length of Titanic, 3 hours and 14 minutes

Stand tall. Be upright. Stay firm.
