In this video, Dr. Rena Malik explains what morning erections really indicate about your hormonal health, blood flow, and overall sexual function. She breaks down the medical reasons behind changes in morning wood and what it means for your long-term health. Watch now to understand what your body is telling you—and what to do about it.

05:36 BottomlineIf you've noticed fewer morning erections as you get older, you're not alone. But here’s the truth: morning wood — medically called nocturnal penile tumescence — is more than just a random biological event. It’s a powerful indicator of your overall vascular, hormonal, and neurological health.

What it means if you stop getting them
And most importantly — how to fix it
What Is Morning Wood, Really?
Contrary to popular belief, morning erections aren't just a result of sexual dreams. They are a natural physiological process that happens during REM sleep, the phase when dreaming is most intense.
During REM sleep, there’s increased activity in the parasympathetic nervous system — the part of your nervous system responsible for relaxation and "rest and digest" functions. This state promotes blood flow to the genitals, leading to spontaneous erections multiple times throughout the night.
Most men wake up during or just after REM sleep, which is why they often notice an erection first thing in the morning.
How Often Should You Have Morning Erections?
Healthy males typically have 3 to 5 erections per night, even without any sexual stimulation. This starts as early as childhood and peaks during adolescence.
Teens: Up to 40% of total sleep time involves erections, with episodes lasting up to 40 minutes each.
Adults: As men age past puberty, this reduces to around 20% of sleep time, or about 90 minutes total per night.
Interestingly, REM sleep remains fairly consistent throughout adult life (about 100 minutes per night), meaning that changes in morning wood aren't caused by reduced REM sleep — but by other physiological changes.
Why Morning Erections Decline With Age
There are several age-related factors that contribute to the decline in frequency, firmness, or duration of morning erections:
Reduced Blood Flow
A 2020 study of healthy men aged 20–60 found that although all age groups still experienced nighttime erections, blood flow decreased with age:
Age 20s: blood flow increased to 268% of baseline during erections
Age 50s: only about 200% — still strong, but notably reduced
Hormonal Changes
Testosterone is a key driver of sexual health, and low levels can impair both spontaneous and intentional erections. One of the earliest signs of low testosterone is the disappearance of nocturnal or morning erections.
Vascular Health
Erections require healthy arteries and capillaries. As men age, issues like high blood pressure, cholesterol buildup, and vascular stiffness can impair blood flow.
Nerve Function
Proper nerve signaling is required to trigger nocturnal erections. Neurological disorders (diabetes, spinal injuries, etc.) or chronic stress can impair this.
What It Means If Morning Erections Disappear
If you're no longer waking up with erections — or if it's happening far less frequently — this is a red flag. It doesn't just affect your sex life; it's a biomarker for your overall health.
Morning wood requires:
Healthy blood vessels
Balanced hormones (especially testosterone)
Good sleep (especially REM sleep)
Proper nerve function
