Erectile dysfunction (ED) is a very common sexual condition that affects men of all ages due to a variety of potential underlying factors. One study from 2013 concluded that ED affects over one-quarter of all men under 40. The condition becomes more common as men age.

The good news is that modern pharmaceutical research in recent decades has delivered treatments that prove quite effective at treating ED for many men. And more recently, telemedicine has advanced to the point where you can access these prescription treatments with just an internet connection and then get them delivered directly to your front door.

BlueChew ED medication is one of the most well-known options of this kind to treat erectile dysfunction, and its treatments are effective for many men. But how does it work, and what does successful treatment look like? One of the most common searches people perform on our website is for "BlueChew before and after pictures." On this page, we’ll show how BlueChew works using the latest 3D imaging technology.

What is an erection?

Contrary to popular beliefs that men can get an erection and have an orgasm at the drop of a hat, in reality, there are several intricate things happening in order to make that erection possible.

  • Psychologically, a man must be relaxed enough and in a healthy mindset to be properly aroused. If a man is under intense stress or dealing with depression, for example, ED may result. (Sleep disorders can ultimately cause ED as well.)
  • Physically, an erection is the result of signaling from the brain to the nerves in a man’s genital region. Erections can only happen if the brain can effectively signal to the parasympathetic nervous system (via the cavernous nerve) that it ought to happen.
  • Blood must be able to flow sufficiently into the spongy tissues of the penis. Underlying conditions like high blood pressure, atherosclerosis, and type 2 diabetes can lead to ED because of insufficient blood flow or long-term damage to nerves and blood vessels. (Thankfully, the prescription medications present in BlueChew have been shown in studies — such as a study from 2018 — and in medical practice to help many men with diabetes achieve erections in spite of ED.)

There are actually three kinds of erections:

Reflexogenic erection

Physical touching of a man's genitals stimulates a man and causes an erection.

Psychogenic erection

Absent any physical stimulation, a person’s memories and thoughts can cause an erection by themselves.

Nocturnal erection

When men are asleep, they get nocturnal erections.

Important penis anatomy to understand

Since we've already mentioned the cavernous nerve above, it's time to give a brief overview of the penis anatomy that is important for understanding erections.

Penis image labeled with important anatomical features

The penis is the largest part of the external male genitalia and is commonly divided into three parts:

  1. The root
  2. The body or shaft
  3. The glans

The root anchors the penis to the pelvic bones while both the body and the glans expand and harden noticeably during an erection. The body (or shaft) of the penis is composed of three columns: the two corpora cavernosa and the corpus spongiosum. These three corpora and associated blood vessels give the penis its erectile, sexual function.

  • The corpora cavernosa are made of sponge-like tissue that becomes engorged with blood during an erection.
  • The corpus spongiosum surrounds the penile urethra. It also becomes somewhat engorged but to a lesser extent than the corpora cavernosa. This is because the urethra must remain open to provide a viable channel for ejaculation.

The urethra allows urine and semen to exit the body. Meanwhile, the sensation of the penis is provided by the dorsal nerve of the penis, a branch of the pudendal nerve. Important signaling from the brain is received by the cavernous nerve.

What happens during an erection, step by step

What causes an erection varies depending on the type of erection. But to explore each step in the process of getting an erection, let’s consider the case of a reflexogenic erection.

  1. A pleasurable sensation in the penis — such as from a touch — is registered by the dorsal nerve of the penis, which sends information to the brain.
  2. Activating the parasympathetic nervous system, the brain sends a signal to the cavernous nerve, which triggers the release of nitric oxide (NO) from endothelial cells in the penis.
  3. There's a reason why many fitness buffs associate nitric oxide with improved blood flow during workouts. That's because, vascularly downstream, NO prompts the production of a molecule called cyclic guanosine monophosphate (cGMP), which causes blood vessels to dilate (widen in diameter). In this case, the NO released from cells in the penis causes cGMP to increase within the penis. This cGMP relaxes the smooth muscles in the blood vessels of the penis — yes, there are muscles inside of the blood vessels — and this relaxation causes the vessels to dilate. (This is called vasodilation.)
  4. Consequently, the dorsal artery of the penis and the deep cavernous arteries dilate, leading to about 20-40 times the normal amount of blood flow and filling the corpora cavernosa with blood.
  5. At the same time, the swelling of these tissues compresses veins and significantly reduces the outflow of blood through veins from the penis — particularly the emissary veins but also partly the deep dorsal and circumflex veins that the emissary veins drain into. (This is called venous occlusion.) The combination of vasodilation of arteries and venous occlusion means that an unusual amount of blood is now collecting within the penis. The corpora cavernosa continue to engorge, and the penis becomes fully erect, with assistance from the corpus spongiosum.
  6. So, why don't guys get permanent erections? This is where phosphodiesterase type 5 (PDE5) enters the picture. PDE5 is an enzyme that the body releases to bind to cGMP and metabolize it. PDE5 reduces how much cGMP is free to relax the smooth muscles of the blood vessels supplying blood to the penis. In other words, with enough PDE5 to metabolize cGMP, the blood vessels don't remain dilated, so blood flow reduces and returns to normal. As swelling subsequently reduces, this permits blood to depart the penis via veins that are no longer constricted. And thus, the erection subsides.

That's what happens during a normal erection. But what happens during untreated ED?

Erectile dysfunction is the inability to get and/or maintain a penile erection that is firm and/or enduring enough for sex. Below is an interactive, 3D animated picture showing the penis of a man before pursuing ED treatment such as BlueChew. You can interact with the picture by zooming in or out, rotating it, or clicking specific anatomical objects to gain deeper information.

As you see in the image above, the penis is unable to become fully erect. There are many possible underlying causes for ED. It can occur due to physical or psychological causes that affect any of the areas of the brain, reproductive hormones, emotions, nerves, muscles, and/or blood vessels that are involved with the phenomenon of erection.

However, some underlying causes are more common than others. The most common physical causes of ED include heart disease, atherosclerosis (clogged blood vessels), high blood pressure, nerve damage, type 2 diabetes, and stroke, among others. The most common psychological causes include stress, anxiety, depression, or communication issues with the sexual partner. (Complicating matters, ED itself can cause stress, anxiety, depression, and communication issues.)

Some men with ED are able to get a full erection, but it doesn't last long enough to engage in sexual activity. Other men aren't able to get fully erect — as the 3D picture below depicts — or don't see any physically noticeable changes in their penis.

A doctor is able to determine whether ED medication, such as the ones offered by BlueChew, would be a good first course of action. And if so, the doctor can also help you determine which specific medication — sildenafil, tadalafil, vardenafil, or avanafil — is the best starting point for you.

The ED medications available from BlueChew can be very effective in treating erectile dysfunction caused by common physiological factors like insufficient blood flow. No available medications actually cure ED because they do not address underlying health issues that cause it. Instead, they provide treatment by allowing men to achieve erections.

For those who prefer static pictures to interactive animations, below you can see a labeled picture showing what happens when ED medication from BlueChew enables the normal increase in blood flow that occurs inside the penis after the brain signals to the cavernous nerve that an erection should occur. In contrast to the cross-section image of the non-erect penis much earlier in this article, here you can see how the spongy corpora cavernosa (and, to a lesser extent, the corpus spongiosum that surrounds the urethra) have engorged with blood to enable an erection.

The influx of blood to the penis also causes constriction of veins that would have allowed blood to leave the penis. Here is an image showing how that buildup of blood culminates in an erection.

Chewable treatments from BlueChew contain sildenafil, tadalafil, or vardenafil — the same active ingredients found in prescription Viagra, Cialis, and Levitra, respectively. All of these medications are classified as PDE5 inhibitors because they all facilitate vasodilation in the penis in a similar way.

As described earlier, when the brain activates the parasympathetic nervous system via the cavernous nerve in the penis, it triggers the release of nitric oxide (NO), which, in turn, triggers the production of a molecule called cyclic GMP (cGMP). That molecule acts to relax the smooth muscles in the blood vessels of the penis, and this relaxation causes them to dilate, leading to much more than the normal amount of blood entering the spongy tissues of the penis and causing an erection. PDE5 is the enzyme that binds to and neutralizes cGMP, subsequently causing blood vessels to return to their normal, pre-dilated state and ending an erection.

A PDE5 inhibitor — the type of ED medication you get in BlueChew — binds with the PDE5 enzyme in your body so that it can't bind with the cGMP. This intervention has proven to be effective for many men with ED to achieve erections that are strong, safe, and long-lasting enough for satisfying sex.

Will BlueChew work this way for everyone?

BlueChew will not work this effectively for everyone — it's not a universal treatment because:

  • The underlying causes of ED are sometimes not physiological; if your ED has psychological roots, then this will likely not be your solution.
  • When physiological causes are at work, sometimes underlying health conditions make the use of PDE5 treatments unsafe or inadvisable.

For many men with ED, though, the medications in BlueChew are safe and effective ways to get an erection.
