The penis is not a muscle, but it does contain some muscle fibres that help with erectile function. The penis is made up of a mix of tissues, glands, and muscle fibres that work together to create an erection. The penis is also not a bone, despite popular nicknames like boner. It is made up of three cylinders: two corpora cavernosa and one corpus spongiosum, which fill with blood during an erection. The penis is surrounded by muscles that help to maintain an erection and control bladder and sexual function.
| Characteristics | Values |
|---|---|
| Is the penis a muscle? | No, it is not a muscle but contains a few muscle fibres and muscles around blood vessels that are involved with producing an erection. |
| Is the penis a bone? | No, it does not contain any bones. |
| What is the penis made of? | The penis is made up of a mix of tissues, glands, muscle fibres, blood vessels, veins, arteries, nerves, ligaments, skin, and collagen. |
| What is the function of the penis? | The penis is the male sex organ and is a part of the reproductive system. It is used for sexual pleasure, urination, and reproduction. |
| What is the average penis size? | Research shows that a person's perception of penis size is often skewed, with many overestimating the "normal" or average size. There is no consistent relationship between the size of a flaccid penis and its full erect length. |

What You'll Learn
The penis is not a muscle
The penis is made up of three parts: the root, the body, and the glans. The root is the most proximal, fixed part of the penis and is located in the superficial perineal pouch of the pelvic floor. It contains three erectile tissues (two crura and the bulb of the penis) and two muscles (ischiocavernosus and bulbospongiosus). The ischiocavernosus muscles surround the left and right crura of the penis and help maintain an erection by forcing blood from the cavernous spaces in the crura into the corpora cavernosa. The bulbospongiosus muscle is associated with the bulb of the penis and helps to empty the urethra of any residual semen and urine.
The body of the penis is located between the root and the glans and is composed of three cylinders of erectile tissue: two corpora cavernosa and the corpus spongiosum. The corpora cavernosa contains spongy tissue and arteries that fill with blood during arousal, causing an erection. The corpus spongiosum contains the urethra, which allows the passage of urine from the bladder to the urethral opening.
The glans is the most distal part of the penis and is formed by the distal expansion of the corpus spongiosum. It contains the opening of the urethra, called the external urethral orifice. While the penis may be referred to as a "boner" or "love muscle", these nicknames are inaccurate, as the penis does not contain any bones and is not primarily composed of muscle.

It is made up of a mix of tissues, glands, and muscle fibres
The penis is not a muscle, but it does contain a few muscle fibres. It is made up of a complex mix of tissues, glands, and muscle fibres. The penis is a male sex organ that is part of the male reproductive system. It is made up of three parts: the root, body, and glans. The root is the most proximal, fixed part of the penis, located in the superficial perineal pouch of the pelvic floor. The body is the free part of the penis, located between the root and glans and is suspended from the pubic symphysis. The glans is the most distal part of the penis and is conical in shape. It contains the opening of the urethra, called the external urethral orifice.
The penis contains soft, spongy tissue as well as muscles, fibrous tissue, veins, arteries, and the urethra. These structures allow the penis to perform its functions, including sexual reproduction and urination. During arousal, the penis fills with blood, causing an erection. The penis does not contain any bones, but there is a risk of injury called a "penile fracture" if it is bent too forcefully.
The penis contains a series of muscles around blood vessels that help produce an erection. The ischiocavernosus and bulbospongiosus muscles, as well as the smooth muscle tissue within the penis, work together to make the erection hard and steady. The muscles also help to seal off the blood during an erection and relax to allow the penis to return to a flaccid state afterward.
The penis also contains elastic tissues and fibres that help the erection stay hard and stiff. The corpora cavernosa and corpus spongiosum are the spongy tissue segments that hold blood for erectile function, while the tunica albuginea is the fibrous tissue that protects them. The penis relies on muscles both internally and externally to function properly and maintain its flexibility and range of motion.

Muscles are involved in producing an erection
The penis is not a muscle, but it does contain some muscle fibres and is surrounded by muscles that are involved in producing an erection. The penis is made up of a mix of tissues, glands, and muscle fibres that work together to create an erection.
During an erection, the penis fills with blood, causing it to stiffen and harden. This process is supported by the muscles around the penis, which help to maintain the erection and increase the pressure in the penis, making it hard and steady for sexual penetration. The ischiocavernosus muscles, bulbospongiosus muscle, and the smooth muscle tissue within the penis all work together to achieve this.
The ischiocavernosus muscles surround the left and right crura of the penis and help to force blood from the cavernous spaces in the crura into the corpora cavernosa, which aids in maintaining an erection. The bulbospongiosus muscle is associated with the bulb of the penis and helps to empty the urethra of any residual semen and urine. It also aids in maintaining erection by increasing the pressure in the bulb of the penis.
Additionally, the muscles in the perineal area and pelvic floor, as well as the crura and suspensory ligament, are internal structures that assist in sexual function and contribute to achieving and maintaining an erection. These muscles work together with the tissues and glands in the penis to facilitate sexual arousal and erection.
While the penis itself is not a muscle, the muscles surrounding it and the muscle fibres within it play a crucial role in producing an erection and supporting sexual function.

There are no bones in the penis
While the penis is near the pubic bone and the other bones of the pelvis, it is not a bone itself. There are no bones in the penis, nor are there any in the reproductive system in general. The most important bones for the penis are actually buried beneath the surface, where they protect and create structure for internal structures of the reproductive system that lead to or connect with the penis.
The penis is not a muscle either, though it does contain a few muscle fibres and use muscles to function. The ischiocavernosus muscles, bulbospongiosus muscle, and the smooth muscle tissue within the penis all work together to make an erection hard and steady its erect direction for sexual penetration. The penis is made up of a mix of tissues, glands, and muscle fibres that work together to create an erection. The penis is a collection of blood vessels, vascular structures, connective tissue, and nerves. The majority of the penis's structure is designed to collect and capture blood, inflate, and become firm enough for penetrative sexual intercourse.
The penis is made up of three parts: the root, body, and glans. The root is the most proximal, fixed part of the penis and is not visible externally. The body is the free part of the penis, located between the root and glans. It is composed of three cylinders of erectile tissue – two corpora cavernosa and the corpus spongiosum. The glans are the most distal part of the penis and is conical in shape. It contains the opening of the urethra, termed the external urethral orifice.
The penis can gain a notable amount of length when erect, known as a "grower", or it can stay around the same length, known as a "shower". The average change in length between showers and growers is only an inch and a half.

The penis is part of the male reproductive system
The penis is indeed part of the male reproductive system, which is responsible for sexual function and urination. The penis is also used for sexual intercourse and contains many sensitive nerve endings.
The penis has three parts: the root, body, and glans. The root is the most proximal, fixed part of the penis and is located in the superficial perineal pouch of the pelvic floor. It contains three erectile tissues and two muscles: the ischiocavernosus and bulbospongiosus. The body is the free part of the penis, located between the root and glans. It is composed of three cylinders of erectile tissue: two corpora cavernosa and the corpus spongiosum. The glans is the most distal part of the penis and is conical in shape. It contains the opening of the urethra, termed the external urethral orifice.
The penis does not contain any bones or major muscles. However, it does contain some muscle fibres that help with erectile function. The ischiocavernosus, bulbospongiosus, and smooth muscle tissue within the penis work together to make the erection hard and steady. The penis is a collection of blood vessels, vascular structures, connective tissue, and nerves. The majority of its structure is designed to collect and capture blood, inflate, and become firm enough for penetrative sexual intercourse.
The penis is surrounded by other parts of the male reproductive system, both internal and external. The external structures include the scrotum, testicles, and epididymis. The internal organs include the vas deferens, prostate, and urethra. The male reproductive system also includes the brain, which controls the release of sex hormones and is involved in arousal.
