The penis is not a muscle, but it does contain a few muscle fibres and muscles that help with erectile function. The penis is a complex assortment of glands, specialised tissues, blood vessels, vascular structures, connective tissue, and nerves. The ischiocavernosus muscles, bulbospongiosus muscle, and the smooth muscle tissue within the penis work together to make an erection hard and steady its erect direction for sexual penetration.

What You'll Learn
The penis is not a muscle, but it does contain muscle fibres or muscles
The penis is not a muscle, but it does contain muscle fibres and muscles that play a crucial role in its function. While nicknames like “boner” and “love muscle” are commonly used, they are not anatomically accurate. The penis is a complex structure composed of various tissues, glands, blood vessels, and nerves, with muscle fibres and muscles supporting its erectile function.
The penis contains smooth muscle fibres around blood vessels, as well as fibroelastic tissue, connective tissue, and some muscles at its base. These muscles, including the ischiocavernosus and bulbospongiosus, help facilitate erections by managing the blood flow into the corpora cavernosa, which are the spongy tissue segments that fill with blood during an erection. Additionally, the bulbospongiosus muscle aids in emptying residual semen and urine from the urethra.
The penis also relies on external muscles for movement and function. These include the muscles of the perineal area and pelvic floor, as well as the crura and suspensory ligament, which are internal structures that contribute to both urinary and sexual function. Sexual arousal triggers signals that travel through the nervous system, instructing the penis to become erect with the support of these muscles.
While the penis itself is not a muscle, the presence of muscle fibres and muscles within and around it are essential for its ability to achieve and maintain erections, as well as for other reproductive and urinary functions. These muscles work in conjunction with the tissues, glands, and blood vessels of the penis to enable its various functions. Understanding the anatomy of the penis can help promote good penis health and dispel common misconceptions.

The penis is part of the male reproductive system or sex organ
The penis is indeed part of the male reproductive system and sex organ. It is made up of a complex assortment of glands, specialised tissues, and some muscle fibres that help with erectile function. The penis is not a muscle, although it does contain a few muscle fibres that help manage the trapped blood that makes up erections. The penis is also surrounded by muscles that enable movement and help make penetration and urination possible.
The penis has three parts: the root, body or shaft, and the glans. The root is the most proximal, fixed part of the penis, 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 the 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 is the male organ for sexual intercourse and contains many sensitive nerve endings. The corpora cavernosa and corpus spongiosum are made up of spongy tissue and arteries that fill with blood during sexual arousal, causing the penis to become hard and rigid. This process is managed by the muscles around the corpora cavernosa, which relax to allow blood flow and pressure that results in an erection.
The penis is part of the male reproductive system, which includes external genitalia such as the penis, testes, and scrotum, as well as internal parts like the prostate gland, vas deferens, and urethra. The system is responsible for sexual function, fertility, and reproduction, with the penis specifically designed for urination and sexual intercourse.

The penis contains spongy tissue and blood vessels
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 complex assortment of glands, specialised tissues, and blood vessels. The penis contains spongy tissue and blood vessels, which fill with blood when a person gets an erection. The corpora cavernosa and corpus spongiosum are the spongy tissue segments that hold blood for erectile function. The corpus spongiosum is a single structure that lies in the ventral groove between the two corpora cavernosa. The urethra passes through the corpus spongiosum.
The corpora cavernosa are two chambers of the penis that fill with blood to create an erection. The corpora cavernosa contain erectile tissue and are each surrounded by the tunica albuginea, a dense fibrous sheath of connective tissue with relatively few elastic fibres. The corpora cavernosa communicate freely through an incomplete midline septum. The erectile tissue within the corpora cavernosa contains arteries, nerves, muscle fibres, and venous sinuses lined with flat endothelial cells. When the muscles around the corpora cavernosa relax, blood flows into its open spaces, causing the penis to swell and stiffen.
The penis is drained by three venous systems: the superficial, intermediate, and deep. Venous drainage of the penis occurs through the superficial dorsal vein, the deep dorsal and circumflex veins, and the circumflex or deep dorsal veins. The penile shaft is composed of three erectile columns: the two corpora cavernosa and the corpus spongiosum, as well as the columns' enveloping fascial layers, nerves, lymphatics, and blood vessels, all covered by skin.
The penis is not a bone either, nor does it contain any bones. However, there is an injury called "penile fracture" that can occur when an erect penis is bent forcefully.

The penis is made up of glands, tissues, and ligaments
The penis is not a muscle, but it does contain some muscle fibres that help with erectile function. The penis is made up of glands, tissues, and ligaments.
The penis is anatomically divided into two continuous areas: the body, or external portion, and the root. The root of the penis is the most proximal, fixed part of the penis and is located in the superficial perineal pouch of the pelvic floor. It is not visible externally. The root contains three erectile tissues (two crura and the bulb of the penis), and two muscles (ischiocavernosus and bulbospongiosus). The ischiocavernosus muscles, bulbospongiosus muscle, and the smooth muscle tissue within the penis work together to make erections hard and steady.
The body of the penis 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 corpora cavernosa contain erectile tissue and are each surrounded by the tunica albuginea, a dense fibrous sheath of connective tissue. The corpus spongiosum is a long cylindrical body of tissue that extends through the body of the penis to the tip, where it expands into a mushroom-shaped structure called the glans penis. The glans penis 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 root and body of the penis are spanned by three masses of erectile tissue. The erectile tissues fill with blood during sexual arousal, producing an erection. The penis is supported by two ligaments that attach it to the surrounding structures: the suspensory ligament and the fundiform ligament.

The penis can be referred to as a grower or a shower
The penis is not a muscle, but rather a collection of blood vessels, vascular structures, connective tissue, and nerves. It does, however, contain some muscle fibres that help with erectile function. The ischiocavernosus muscles, bulbospongiosus muscle, and the smooth muscle tissue within the penis work together to make an erection hard and steady.
Now, onto the colloquial terms "grower" and "shower". A "shower" refers to a penis that does not change much in length from its flaccid to its erect state. On the other hand, a "grower" is a penis that experiences a notable increase in length when erect. The average change in length between showers and growers is only about an inch and a half, and this difference does not seem to have any impact on one's sex life. Tissue elasticity, collagen levels, and genetics all play a role in determining whether someone is a shower or a grower, and these factors can change over time, causing one's category to potentially change as well.
