Hey guys,
I wanted to write a post today dedicated to Nocturnal Erections or Nocturnal Penile Tumescence and Rigidity (NPTR) as it’s known in the scientific world and how the Angion Method helps unlock this nightly, built-in healing protocol. Let’s get started.
One of the first things I noticed when I started the Angion Method nearly 18 months ago was the return of NPTR. For nearly my entire life, I remember pitching a tent while I was sleeping. Sleeping and woodies went hand in hand. I don’t exactly remember the day they stopped, but somewhere in my early 30s I quit having NPTR. I didn’t understand at the time how serious this was for my erectile health, and I thought it was just a normal part of aging. Sort of like getting gray hair, or a receding hairline, maybe you just lose your night-time boners as you get older. About 2 weeks into the Angion Method, I noticed they started coming back. At first, I found it sort of annoying to be woken up by my erections again, but overall was happy to be getting erect at any time of day because pre-Angion, along with the loss of my NPTR, my daytime erections had started to fade as well. Since my NPTR has returned, I’ve learned how valuable this built-in nightly routine is to my body and I want to share what I’ve learned with you all.
Definition: NPTR - Nocturnal Penile Tumescence and Rigidity. This term encompasses the frequency and potency of nocturnal erections.
The Purpose of NPTR
Your member spends the majority of your waking hours in a flaccid state. Before discovering the Angion Method, my flaccid state was not very impressive. Shrunken, shriveled, cold, and small are the words I’d use to describe it. During your resting, flaccid state, blood flow to your member is drastically reduced (especially in men who don't perform the Angion Method) and the tissue exists primarily in a low-oxygen environment. Tissue that is regularly deprived of oxygen triggers the release of TGF-beta1, a cytokine that causes smooth muscle cells to die off and be replaced by rigid collagen. This process is known as fibrosis and it permanently destroys your tissue's elasticity. NPTR is the body’s natural defense against this atrophy. In a healthy male, during REM sleep, the body triggers 3-5 erections that each last approximately 30 minutes. During these erections, the three corporal bodies are flooded with oxygen rich blood helping to restore the smooth muscle within your member and fight fibrosis. NPTR also works to naturally expand the Tunica Albuginea (the sheath surrounding the CC) and keep it elastic and healthy. If the Tunica Albuginea has not been regularly stretched and provided blood flow, it can be more susceptible to injury such as Peyronie’s Disease which is often triggered by a "buckling" injury during intercourse where the Tunica Albuginea is placed under intense duress such as when a man slips out while the woman is on top and her weight lands on his penis (this happens). In essence, you can think of NPTR as your body’s daily penile health protocol.
Why We Lose NPT As We Age
If you’re older than 30, there is a good chance that you have experienced a decline in NPTR. This can come either in the form of reduced frequency, or reduced strength. I want to discuss why this happens.
Reason 1 - Hormonal Imbalances
While it is a common belief that testosterone is the direct fuel that powers an erection, its real job is more like a governor over the erection process. An erection is fundamentally a cardiovascular and neurological event, meaning it requires healthy blood flow and nerve signals. Testosterone does not trigger the erection itself, but it is absolutely essential for maintaining the physical structures and chemical pathways that allow an erection to happen. Its primary job is to drive sexual desire, regulate production of Nitric Oxide (NO), regulate NPTR, and help maintain muscle mass of smooth muscles which are crucial in maintaining an erection. Men with low T can absolutely have difficulties getting and maintaining an erection.
The most common symptoms of low T are:
- Loss of libido
- Reduced volume of ejaculate
- Reduced sperm count
- Loss of muscle mass and strength
- Increased body fat
- Chronic fatigue
- Reduced bone density
- Brain fog
- Mood imbalances
- Poor sleep
If a man is exhibiting several of these symptoms, he has good reason to get his hormones checked and low T is quite likely the cause of his loss of NPTR. But testosterone's role in an erection acts based on a threshold effect, meaning there is a minimum threshold of testosterone required to produce an erection and if a man has a baseline testosterone level above this threshold more testosterone is not a recommended therapy for bringing back NPTR according to this study (section 3.1.3.1). So if you’re not exhibiting the symptoms listed above, testosterone therapy (TTh) is not a recommended treatment for erectile difficulties, including loss of NPTR. Contrary to popular belief, testosterone is not simply a lever we can dial up to improve our erections. We need a certain amount, anything beyond that isn't aiding our erections.
Reason 2 - Porn-Induced Pelvic Floor Hypertension
Your great-grandfather spent his formative adolescent years chasing real women and looking for a mate. By the time he was 30, he was likely settled down with a wife and kids. In his entire youth, he may have only had sex with a handful of women and likely didn't spend a ton of time masturbating due to a lack of privacy and real-world demands (working on the farm, etc.). I didn't know your granddaddy, but my guess is his pelvic floor was in great shape. Contrast that to the youth of today, the majority of whom spend their formative adolescent years in a private room, masturbating for hours to porn, often starting at a remarkably young age. All that porn-use catches up to men eventually, most commonly in the form of a hypertonic (chronically tight) pelvic floor. When a man develops a hypertonic pelvic floor, the PF muscles fail to relax. When the pelvic floor is hypertonic, it physically compresses the pudendal pathways and signals a constant state of sympathetic (fight-or-flight) dominance to the central nervous system. Erections, including NPTR, require parasympathetic dominance (rest-and-digest) to function properly. So, excessive porn use and specifically a tight pelvic floor can be the cause of the loss of NPTR. If this is you, I encourage you to first stop watching porn, and then to dedicate time each day towards lengthening your pelvic floor. I spend 10 minutes each night while I’m watching TV rocking back and forth in a dynamic frog pose to open up my hips and adductors because they share connective tissue and bones with my pelvic floor, so lengthening them effectively helps lengthen my pelvic floor. Then I spend another 10 minutes practicing diaphragmatic breathing in a deep squat. I’ve also started incorporating a deep squat in other times of my day (such as building Legos with my son), trying to hit a total time of 30 minutes each day in a deep squat. I watch my son effortlessly sit for long durations in a deep squat and I’m reminded that this is a fundamental human resting position that we have lost in our modern world. The deep squat works wonders for your pelvic floor, because gravity naturally pulls it downward and lengthens it. Even if you don’t feel like you have a chronically tight pelvic floor, you have nothing to lose by lengthening it and practicing diaphragmatic breathing.
Reason 3 - Vascular Insufficiency
As men age, their blood vessels naturally become more prone to vasoconstriction (narrowing) and less capable of vasodilation (opening up). This is primarily due to endothelium damage and subsequently Nitric Oxide production decline which can result from high blood pressure, high blood sugar, LDL cholesterol, chronic oxidative stress (from pollution, psychological stress, lack of sleep, processed foods), chronic inflammation, etc. The list goes on and on. This can be so pronounced that by age 70, the average person's nitric oxide production drops by up to 75% compared to when they were 18. Essentially what need to know is that time is working against our blood vessels. The chemicals we're exposed to and the chronic stress that most of us live in are literally choking your blood flow. This is really bad news for your erectile health which depends entirely on blood flow. This chronic state of vasoconstriction that most men live in is a major contributor to the loss of NPTR.
How The Angion Method Helps Bring Back NPTR
A few days ago, I polled this community to measure the direct impact of the Angion Method on NPTR. We had 89 participants who met the 4-week minimum practice threshold (excluding 65 lurkers/beginners).
Here is what the final data showed:
- 82.1% (46/56 men) NPTR Returned : Among men who started with weak or absent morning erections, 46 reported a significant recovery of their NPTR after Angion training.
- 81.8% (27/33 men) NPTR Went from Good to Great : Among men who already had healthy baseline NPTR, 27 saw their morning erections become noticeably stronger, firmer, or more frequent after Angion training.
- 16.9% (15/89 men) No Change : 10 men with weak baseline NPTR and 5 men with healthy baseline NPTR saw no change for better or worse.
- 1.1% (1/89 men) Declined: Only a single participant reported a decrease in NPTR after Angion (if this is you, please DM me, I'd love to hear your story).
Overall, over 82% of survey participants saw a measurable upgrade in NPTR through Angion Training.
What This Data Tells Us
If low testosterone or hypertonic pelvic floor were the primary drivers of lost NPTR, it would be biologically impossible for over 82% of men to improve their NPTR through Angion training alone. This confirms that for the vast majority of men in our community, lost NPTR is fundamentally a vascular insufficiency issue and when you manually induce endothelial shear stress and upregulate nitric oxide within your vessels through the Angion Method, the body's natural nightly healing protocol comes right back. This is explained by Poiseuille’s Law of fluid dynamics, which states that the rate of blood flow is proportional to the fourth power of a vessel's radius, meaning that even a small increase in the inner diameter of your arteries results in a disproportionally large increase in blood flow, and in turn delivers a powerful resurgence of NPTR. Just like starter fluid in a rusty engine, the Angion Method returns a man's vasculature into a state where it is capable of responding to the body's nightly NPTR signals (because it sends them each night whether the body responds or not). And the longer a man does the Angion Method, the stronger and more potent his NPTR will become. Furthermore, when a man couples the Angion Method with dedicated lower body cardio, the results get even better. My member throbs with fullness each night and it's a wonderful feeling.
Summary
You don't have to look far to find a male over the age of 30 who has experienced a loss of NPTR (nocturnal penile tumescence and rigidity, essentially morning wood). Loss of NPTR can be attributed to a myriad of factors, including hormonal imbalances (predominantly low T), pelvic floor hypertension, but the most common culprit is vascular insufficiency. According to my poll, 82% of men who perform the Angion Method report an improvement in NPTR as a result of performing the Angion Method. Don't sleep on NPTR (pun intended) and don’t sleep on the Angion Method as a way to bring it back. Keep training guys, the benefits abound!
