The penis is not a muscle or a bone. It is a complex organ made up of erectile tissue, connective tissue, and blood vessels. While the penis itself does not contain any muscles, certain muscles are involved in the process of achieving and maintaining an erection. Smooth muscles, which are not under voluntary control, are essential for developing an erection properly. During an erection, smooth muscles in the arteries and veins relax, allowing blood to flow into the penis and resulting in an erection. The bulbospongiosus and ischiocavernosus muscles are also involved in the process of achieving an erection by compressing the veins to prevent blood from draining from the corpora cavernosa.

What You'll Learn
The penis is not a muscle
During sexual arousal, the brain signals the release of nitric oxide, causing the muscles within the penis to relax and allow blood to flow and engorge the organ, resulting in an erection. The corpora cavernosa, or erectile tissue, is responsible for the majority of the penis's rigidity during an erection. It is composed of a network of blood vessels and smooth muscle, allowing it to expand and accommodate increased blood flow.
The penis is made up of three cylinders covered in a sheath called the buck fascia. These cylinders include the corpus spongiosum and two corpora cavernosa, also known as the corpus cavernosum penis. The corpus cavernosum contains spongy tissue and arteries that run along its middle. When the muscles around the corpus cavernosum relax, blood flows into its open spaces, leading to an erection.
The bulbospongiosus and ischiocavernosus muscles are also involved in the process of achieving an erection. They compress the veins to prevent them from draining blood from the corpora cavernosa. Additionally, the bulbospongiosus muscles compress the bulb of the penis and the corpus spongiosum, aiding in emptying the spongy urethra.
While the penis itself is not a muscle, there are muscles nearby that enable movement and support the organ. Stretching and exercising these muscles can help improve sexual performance and control.

Smooth muscles help achieve an erection
While the penis is not a muscle, it does contain smooth muscles that play a crucial role in achieving and maintaining an erection. An erection occurs when the penis fills with blood, causing it to harden and enlarge. This process is made possible by the relaxation of smooth muscles in the arteries and veins of the penis.
Smooth muscles, found throughout the body, function primarily through contraction and expansion. During an erection, the smooth muscles in the walls of arteries relax, allowing blood to flow into the penis. Simultaneously, the smooth muscles in the veins relax to accommodate the increased blood flow and prevent it from flowing out, leading to the engorgement of the penis. This partial restriction of blood flow out of the penis results in the stiffened nature of an erection.
The penis consists of two main parts: the corpora cavernosa and the corpus spongiosum. The corpora cavernosa are two chambers that run the length of the penis and contain a network of blood vessels, erectile tissue, arteries, and veins. The corpus spongiosum, located ventrally, contains the urethra. When the muscles around the corpora cavernosa relax, blood rushes into the open spaces, causing an erection.
Additionally, the bulbospongiosus and ischiocavernosus muscles play a role in maintaining an erection by compressing the veins to prevent blood from draining out of the corpora cavernosa. This compression further contributes to the engorgement and hardness of the penis during an erection.
It is important to note that the penis also has skeletal muscles outside of the corpora cavernosa, but these muscles are not directly responsible for producing an erection. However, exercises such as Kegel or pelvic floor exercises can help strengthen the pelvic floor muscles, improving sexual function and potentially enhancing erections.

Pelvic muscles can make the penis larger, briefly
The penis is not a muscle, but it does have a series of smooth muscles (that are not under voluntary control) to develop an erection properly. Smooth muscles in the arteries and veins of the penis relax to allow blood to flow into and collect within the penis, causing an erection.
While the penis itself does not have muscles that can be exercised to increase its size, the pelvic floor muscles can be exercised to improve sexual health and performance. Pelvic floor exercises, such as Kegels, can help strengthen the pelvic floor muscles, which are important for controlling urinary and bowel functions, as well as sexual function by controlling blood flow to the penis.
By contracting the pelvic floor muscles, one can very briefly make the penis harder and larger, especially during an erection. This increase in hardness and size is known as "thrusting pressure" and only lasts for a few seconds.
It is important to note that there is no exercise or product that has been proven to increase penis size. However, staying active and exercising the pelvic floor muscles can help improve sexual performance and overall health.

Muscles outside the corpora cavernosa do not cause erection
The penis is not a muscle, but it does contain muscles and is surrounded by muscles that enable movement. The penis is made up of three cylinders: two corpora cavernosa and one corpus spongiosum. The corpora cavernosa are two columns of spongy tissue in the shaft of the penis, and they are filled with erectile tissue. This tissue contains nerves, blood vessels, and muscle fibres.
Erection occurs when blood rushes to the penis, and fibrous elastic tissue, smooth muscle, and collagen help support the penis as it transitions from a flaccid to an erect state. Smooth muscles, which are not under voluntary control, are essential for proper erections. Smooth muscles are found in the walls of arteries and veins. During an erection, these muscles relax, allowing blood to flow into the penis and resulting in engorgement.
While there are skeletal muscles outside the corpora cavernosa, they do not produce an erection. The bulbospongiosus and ischiocavernosus muscles are responsible for compressing the veins to prevent them from draining blood from the corpora cavernosa. This compression leads to further engorgement and increased pressure in the glans and corpus spongiosum.

Kegel exercises can improve sexual function
While the penis is not a muscle, it does contain muscles that make movement possible. The penis is made up of three cylinders: two corpora cavernosa and one corpus spongiosum. The corpora cavernosa contain spongy tissue and arteries that run along their middle. The corpus spongiosum contains the urethra.
During an erection, muscles around the corpora cavernosa relax, allowing blood to flow into the penis. Smooth muscles in the arteries and veins of the penis help with this process by relaxing and expanding to collect and hold more blood. This results in the stiffened nature of the penis during an erection.
Kegel exercises can help improve sexual function by strengthening the pelvic floor muscles, which support the pelvic organs. These muscles are vital to sexual function as they play a role in arousal, pleasure, and orgasm response. For men, Kegel exercises can improve erectile function and potentially make orgasms more intense. Women may also find that their orgasms are more intense, and that penetration becomes more comfortable. Additionally, Kegel exercises may improve vaginal lubrication, increase blood flow to the genitals, and enhance sexual arousal.
To perform a Kegel exercise, start by finding the correct muscles. This can be done while urinating by temporarily stopping the flow of urine and noticing which muscles are tightened. For women, this will be felt in the vagina, and for men, in the anus. Another way to locate these muscles is by placing a finger in the vagina or rectum and pretending to try and avoid passing gas.
Once you have located the correct muscles, the proper way to perform a Kegel is to imagine your urethra is a telescope that you are pulling up and into your body. While your abdominal muscles will slightly contract, avoid contracting your buttocks or pulling your abdominals too tightly. Breathe as you normally would during this exercise, inhaling and remaining relaxed, then exhaling as if blowing out birthday candles while simultaneously contracting your pelvic floor muscles. Hold the contraction for 5 seconds, then relax for 5 seconds. Repeat this process 10 times.
