The penis is a fascinating bit of engineering, capable of providing pleasure, reproduction, and urination. Despite being colloquially referred to as a love muscle, the penis is not actually a muscle. Rather, it is composed of spongy tissue that fills with blood during an erection, causing it to swell and stiffen. This process is facilitated by the relaxation of muscles surrounding the corpus cavernosum, which is composed of two tubes of spongy tissue running along the penis. While the penis itself does not contain muscles, there are muscles located in its root and nearby that enable movement, urination, and sexual function.

What You'll Learn
The penis is not a muscle but a sex organ
The penis is the male sex organ used for reproduction and urination. It is located at the base of the pelvis, above the scrotum, and is composed of spongy tissue and arteries that fill with blood during an erection. While the penis itself does not contain any muscles, there are muscles located nearby that enable movement and help with sexual function.
The penis is made up of three cylinders of erectile tissue: two corpora cavernosa and the corpus spongiosum. These cylinders are covered by a sheath called the Buck fascia. The corpora cavernosa contain the spongy tissue and arteries, while the corpus spongiosum forms the glans penis, which is the most distal part of the penis and contains the opening of the urethra.
The root of the penis, which is the most proximal and fixed part, contains two muscles: the ischiocavernosus and the bulbospongiosus. The ischiocavernosus muscle helps to flex the anus and stabilize the erect penis, while the bulbospongiosus muscle is associated with the bulb of the penis and helps to empty residual semen and urine.
The penis is capable of flexing due to the surrounding muscles, particularly the pelvic floor muscles. This flexibility is important for proper penetration during sexual intercourse. However, it is important to note that over-bending or frequent flexing of the penis can lead to cracks or scars in the tissue, potentially resulting in abnormal curvature.
While the penis is not a muscle, it is a complex organ with a fascinating structure and functionality. Its ability to fill with blood and become erect is essential for reproduction and sexual pleasure.

It is made of spongy tissue and has no bones
The penis is not a muscle, but it does contain muscles. The penis is made of spongy tissue and has no bones. It is the male sex organ that is used for reproduction and urination. The penis transports urine from the bladder out of the body when a person urinates. After puberty, the penis also carries sperm and semen out of the body during ejaculation.
The penis is located at the base of the pelvis, above the scrotum, a sac of tissue that contains the testicles. The foreskin is a double-layered ring of tissue that covers the glans, the most distal part of the penis. The foreskin is composed of smooth muscle tissue, blood vessels, neurons, and mucous membranes. The foreskin is retractable and must be cleaned underneath to prevent a buildup of oils and irritants.
The root of the penis is the most proximal, fixed part of the penis and is not visible externally. The root contains three erectile tissues and two muscles: the ischiocavernosus and bulbospongiosus. The ischiocavernosus muscle helps to flex the anus and stabilize the erect penis. The bulbospongiosus contracts to empty the urethra of any residual semen and urine.
The body of the penis is the free part located between the root and the glans. It is composed of three cylinders of erectile tissue: two corpora cavernosa and the corpus spongiosum. The corpora cavernosa contain spongy tissue and arteries that run along their middle. When the muscles around the corpora cavernosa relax, blood flows into their open spaces, causing the penis to swell and stiffen.
The glans is the conical-shaped distal part of the penis that contains the opening of the urethra. The corpus spongiosum expands to form the glans, and it fills with blood at a reduced pressure to prevent the urethra from becoming occluded during erection.

Erection occurs when the spongy tissue fills with blood
The penis is not a muscle, but it does contain muscles that enable movement. It is made up of spongy tissue and arteries that fill with blood when a person is sexually aroused, resulting in an erection.
The penis consists of three cylindrical chambers: the paired corpora cavernosa and the corpus spongiosum. The corpora cavernosa are contained within a bilayered, collagenous sheath called the tunica albuginea. They are composed of variously sized sinusoids supported by a fibrous skeleton. The fibrous skeleton provides structural support and is constructed of tunica albuginea surrounded by smooth muscle trabeculae, which regulate blood flow in and out of the sinusoids. The corpus spongiosum is a single tubular structure located just below the corpora cavernosa. It is composed of spongy tissue and arteries that run along its middle.
When a person becomes sexually aroused, the muscles around the corpus cavernosum relax, allowing blood to flow into its open spaces. This blood flow increases by approximately 20 to 40 times the expanding sinusoids of the corpora cavernosa. As these sinusoids fill with blood, the outer portions of the corpora near the tunica albuginea start to occlude venous outflow. The pressure in the corpora cavernosa rises, causing the penis to swell and stiffen. The pressure in the corpus spongiosum is only one-third to one-half of that in the corpora cavernosa, as the tunical covering ensures minimal venous occlusion.
The ischiocavernosus and bulbocavernosus muscles forcefully compress the spongiosum and penile veins during the rigid-erection phase, resulting in further engorgement and increased pressure in the glans and spongiosum. The bulbocavernosus muscles also aid in maintaining an erection by increasing the pressure in the bulb of the penis.

The penis has muscles nearby that make movement possible
While the penis is often referred to as the "love muscle", it is not actually a muscle. The penis is made of spongy tissue that fills with blood when a person gets an erection. However, there are muscles located nearby that make movement possible. These muscles are crucial for functions such as penetration and urination.
The root of the penis, located in the superficial perineal pouch of the pelvic floor, contains two muscles: the ischiocavernosus and the bulbospongiosus. The ischiocavernosus muscle surrounds the left and right crura of the penis and helps maintain erection by forcing blood into the corpora cavernosa. The bulbospongiosus is associated with the bulb of the penis and aids in maintaining erection by increasing pressure, as well as emptying the urethra of residual fluids.
The penis also has surrounding muscles that play a role in its movement and function. The pelvic floor muscles, located at the base of the penis, create a supportive floor for various organs, including the prostate and bladder. These muscles enable control over urination and contribute to sexual function. Additionally, the ischiocavernosus muscle, situated just below the perineum, assists in stabilising the erect penis and facilitating movement during sexual intercourse.
Kegel exercises are recommended for those seeking to improve their control over the penis. These exercises strengthen the pubococcygeal (PC) muscles, which act as a sling for the pelvic organs. By enhancing the strength of these muscles, individuals may experience improved bladder control and sexual function, potentially leading to a more satisfying sexual experience.

Penis size is often overestimated
While the penis is not a muscle, it does contain muscles that help with movement, urination, and penetration. Interestingly, penis size is often overestimated, and many people wish for a larger penis when, in reality, they have a normal-sized one. Research shows that the average penis size is much smaller than what most people believe it to be, and it usually looks very different from what is portrayed in pornography. The porn industry has been known to showcase male adult film stars with large penises, which does not reflect the true average size. As a result, individuals who watch porn tend to be more dissatisfied with their penis size than those who do not.
Several factors contribute to the overestimation of penis size. Firstly, popular studies that rely on self-reported measurements can lead to inaccurate data. Individuals may provide responses that they believe will be viewed more favourably, resulting in overestimation. Secondly, the perception of penis size as an indicator of testosterone levels and sexual abilities is a common misconception. This belief can cause anxiety and impact self-confidence, especially when comparing oneself to unrealistic standards set by the porn industry.
It is important to understand that penis size does not determine sexual satisfaction or ability to please a partner. Confidence plays a more significant role in satisfaction, both in and out of the bedroom. Additionally, trying new sexual positions, such as doggy style, can enhance sexual experiences regardless of penis size.
For those still concerned about penis size, it is recommended to seek advice from a therapist or mental health expert. Open communication with a partner can also help ease anxiety and improve sexual satisfaction. While penile traction devices and stretching exercises are advertised as methods to increase size, there is little scientific evidence to support their effectiveness. Surgical implantation of a synthetic device is the only option proven to achieve a permanent increase in size, but it is important to carefully consider the risks and complications associated with such procedures.
