Does Low Testosterone Cause Erectile Dysfunction?

Does Low Testosterone Cause Erectile Dysfunction?

Erectile dysfunction has been a problem of men since time immemorial. It’s the unavoidable curse that puts an end to a man’s ability to enjoy the best things in life. Erectile dysfunction isn’t just about the inability to get an erection; it’s the emasculation and humiliation that men feel in those critical situations.

An average man would experience erectile dysfunction at least once before he reaches the age of 40. For some men, having erectile dysfunction is a normal occurrence after the age of 50.

Impotence manifests differently for men, but the severity and probability of impotence could be directly related to low testosterone levels.

To understand why erectile dysfunction happens, it’s important to understand how a normal erection works:

What happens when men get aroused?

Arousal begins with some form of mental stimulation. A man’s sensitivity to sexual arousal is determined by testosterone levels. The brain contains plenty of androgen receptors which when stimulated, creates the notion of libido, or sex drive.

Sexual arousal begins an exchange of messages from the brain to the corpora cavernosa and other blood vessels to simultaneously contract and dilate to increase blood flow to the penis.

The increased pressure and volume prompts the cavernous spaces to expand, creating a hard erection. Once the peak erection size and hardness is achieved, the tunica albuginea, or the membrane surrounding the cavernous spaces, traps the blood to sustain an erection.

The penile artery supplies the blood that fills the cavernous spaces to create an erection. The artery is highly susceptible to damage, stenosis, and occlusion, which could prevent a healthy volume of blood to flow to the penis.

Conditions such as atherosclerosis and high blood pressure could cause erectile dysfunction because it limits the amount of blood that can be trapped in cavernous spaces.

Erectile dysfunction caused by vascular origins is not as common as many people think. Vascular problems normally occur with age, and this could aggravate the actual cause of erectile dysfunction.

The most common cause of erectile dysfunction is low testosterone. With low testosterone, the main drive that initiates an erection is severely impaired.

The desire and motivation to have sex are directly associated with testosterone levels, and having low testosterone levels would greatly reduce the interplay of neurons and androgen receptors, which control penile tumescence.

Not all vascular and hormonal origins of erectile dysfunction result in a complete inability to gain an erection. For most men who suffer from erectile dysfunction, they randomly experience erections, but the threat of erectile dysfunction is ever-present.

In most cases, erectile dysfunction manifests as a weaker erection. Some men may be able to get an erection, but the size and hardness of the erection are significantly reduced. In most cases, men are not aware that they have erections that are smaller than they should be.

According to the Erection Quality Scale (EQS), there are 5 possible erection levels, starting with zero (0) as the complete inability to gain an erection and four (4) as the peak erection size and hardness.

Most men assume that erections are just as hard as they ever will be, but by understanding the EQS and how erections work, you’ll learn that there is a way to gain your peak erection size and hardness.

The Erection Quality Scale (please create a graphic)

erectile dysfunctionClass 0  – Zero change in erection size and hardness

Class 1 – Penis is slightly larger, but not hard

Class 2 – Penis is hard, but not hard enough for penetration

Class 3 – Penis is hard enough for penetration but with reduced size and hardness

Class 4 – Fully-erect penis, completely hard and rigid.

Reduced erection size and hardness may not be considered as erectile dysfunction. Most men have a Class 3 erection and are oblivious to the idea that they may not be getting the biggest and hardest erections they could have. Older men who notice “shrinking” erection are likely to be experiencing Class 3 erections.

Testosterone levels normally decline as men age, and this greatly affects the quality of erections that a man would experience. Reduced testosterone levels would limit the stimulation of the androgenic receptors in the brain, which would reduce the interplay between neuroreceptors during penile tumescence.

Low testosterone isn’t the lone cause of weaker erections in men. Poor blood flow can also reduce erection size and hardness. Men with hypertension, high cholesterol, and diabetes could be experiencing smaller-than-usual erections.

How to Increase Erection Size

Blood flow

Increasing blood flow is a recurring objective for increasing penile size and hardness. Since erections depend highly on optimal blood flow for its size and hardness, the most common solution for erection-related problems is to increase blood flow as much as possible.

In fact, increasing blood flow is so impactful in erectile function that it’s the focal activity of erectile dysfunction medication.

Vasodilation is the key function that helps improve blood flow as it dilates blood vessels to allow a greater blood volume to pass through the blood vessels. This is done by increasing nitric oxide levels in the blood and inhibiting the PDE-5 enzyme.

Nitric oxide helps regulate blood pressure by allowing the smooth muscles in blood vessels to relax, allowing them to dilate. This function effectively improves blood flow issues caused by obstructions in the bloodstream and increases the volume of blood that flows to the corpora cavernosa of the penis. The restriction of PDE-5 prolongs the vasodilatory effects of nitric oxide, allowing for a more robust erection.


Testosterone is the key agent that increases sex drive, and an increase in testosterone greatly increases the sensitivity to sexual stimulus, increasing the likelihood of sexual arousal.

Roughly 60% of all erectile dysfunction cases are related to low testosterone levels. The reduced sensitivity to sexual stimulus limits the amount of acetylcholine released by the brain to trigger the release of Nitric Oxide compounds to dilate blood vessels.

In cases where testosterone is in the “below average” level, which isn’t too low to be considered abnormal, the effect on erection size and hardness is still significant as it can reduce overall flaccid and erect size.

Erection is primarily responsible for the chain of events that lead to an erection, from getting sexually aroused, to focusing blood flow to the penis to gain an erection.

By optimizing your testosterone levels, you can maximize your natural erection size and reduce instances of erectile dysfunction and improve your erection size and hardness.

Penile Tissue Elasticity

The penis is made up of slightly elastic tissue that stretches to contain the engorged cavernous spaces during an erection. The peak size is predetermined by the volume of blood that the cavernous spaces can contain at any given point, and how much the penile tissue can expand to accommodate the increased blood flow.

In theory, certain muscle fibers and tissue can be stretched through an exercise to become more flexible, much like how people stretch before working out.

When it comes to penis enlargement, exerting an external force to forcibly stretch the penile tissue may be beneficial for the tissue and fibers to be more adaptable to the increased blood volume and pressure brought about by penile tumescence.

In any case, penile tissue elasticity is an important aspect of penis enlargement since it limits the growth and peak erection size, but it shouldn’t be a major concern for men who have regular erections.

By having regular, robust erections, men can prevent the rigidity of penile tissue as the tissue regularly expands and contracts during an erection.

Testosterone Supplements

Performance-enhancing testosterone supplements are highly capable of normalizing and even increasing your peak erection size. The best testosterone-boosting supplements, such as Male UltraCore, are equipped with testosterone-boosting ingredients and vasodilators to greatly enhance your physical and sexual performance.

Male UltraCore is powered by potent standardized extracts and natural ingredients that work together to efficiently elevate testosterone levels and promote a healthy circulatory system.

Unlike erectile dysfunction drugs that work exclusively on inducing erections, Male UltraCore has a comprehensive performance-enhancement formula that increases libido, sexual performance, size, and stamina to help you deliver the intimate performance that your partner will never forget.

Male UltraCore does not require a prescription to purchase, and it directly addresses the root causes of erectile dysfunction, unlike drugs that only tackle the symptom.


Erectile dysfunction is one of the many problems that men with low testosterone face on a daily basis. Low testosterone is a tremendous problem for men, but it has a remarkably simple solution. Taking testosterone supplements every day will help restore your normal testosterone levels.

Weaker erections are just as bad as having erectile dysfunction. Having weaker erections is an indication that your testosterone levels are declining, and it may not take long before it develops into a full-blown case of ED.

Erectile dysfunction is not a condition that develops overnight. More often than not, there are telltale signs that your body is slowly declining, and you need to take action before it develops into something much worse.

Prevention is always better than cure. I’m sure any man who has erectile dysfunction would jump at the opportunity to take testosterone supplements back when the symptoms started, rather than taking erectile dysfunction pills just to induce an erection.
