The penis is not a muscle, but it does contain a few muscle fibres that help with erections. The penis is a complex mix of tissues, glands, muscles, and fibres that work together to create an erection. 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, known as the corpus cavernosum penis. The spongy tissue in the penis fills with blood when a person gets an erection.

What You'll Learn
The penis is not a muscle
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, known as the corpus cavernosum penis. The corpus cavernosum contains spongy tissue and arteries that run along the middle of each. When the muscles around the corpus cavernosum relax, blood flows into its open spaces, causing the penis to swell and stiffen.
The penis is part of the male reproductive system, which includes the muscles of the perineal area and pelvic floor, as well as the crura and suspensory ligament. These internal structures assist in urinary and sexual function. The penis itself is not a muscle, but it does contain some muscle fibres that help with erectile function.
The penis is often referred to as a "boner" or "love muscle", which can be misleading. While the penis does contain some muscles, it is primarily made up of other tissues and glands. 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 also surrounded by muscles that help with sexual functions such as penetration and urination. These muscles include the ischiocavernosus muscles, the bulbospongiosus muscle, and the smooth muscle tissue within the penis itself. These muscles work together to make the erection hard and steady its direction for sexual penetration. Sexual arousal occurs when signals travel down the spinal cord through the nervous system, telling the penis to become erect.

The penis contains muscles
While the penis is not a muscle, it does contain muscles. These muscles are located in the root of the penis, which is the most proximal, fixed part of the penis located in the superficial perineal pouch of the pelvic floor. There are four muscles in the root of the penis: two bulbospongiosus muscles and two ischiocavernosus muscles. The bulbospongiosus muscles are associated with the bulb of the penis and contract to empty the urethra of any residual semen and urine. The ischiocavernosus muscles surround the left and right crura of the penis and contract to force blood from the cavernous spaces in the crura into the corpora cavernosa, which helps maintain an erection.
The penis also contains smooth muscle fibres around an extensive series of blood vessels within the penis. These muscles work together to create an erection. When a person is aroused, the smooth muscles in the arteries relax, opening them up and allowing the penis to fill with blood and an erection to occur. The ischiocavernosus, bulbospongiosus, and smooth muscle tissues within the penis work together to make an erection hard and steady its erect direction for sexual penetration.
The penis is a complex assortment of glands, specialised tissues, and muscle fibres that help with erectile function. The penis is also made up 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.

Muscles are involved in producing an erection
The penis is not a muscle, but it does contain some muscle fibres that help with erectile function. The penis is a complex assortment of glands, specialised tissues, and muscle fibres. 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 three cylinders covered in a sheath called the buck fascia. These cylinders include the corpus spongiosum and two corpora cavernosa, known as the corpus cavernosum penis. The corpus cavernosum contains spongy tissue and arteries that run along the middle of each. When the muscles around the corpus cavernosum relax, blood flows into its open spaces, creating pressure that causes the penis to swell and stiffen.
The root of the penis contains three erectile tissues (two crura and the bulb of the penis) and two muscles (ischiocavernosus and bulbospongiosus). The ischiocavernosus muscle surrounds the left and right crura of the penis. When a person is aroused, the ischiocavernosus muscle contracts to force blood from the cavernous spaces in the crura into the corpora cavernosa, which helps to maintain an erection. The bulbospongiosus muscle, associated with the bulb of the penis, also plays a role in maintaining an erection by increasing the pressure in the bulb.
During sexual arousal, the penis fills with blood, causing an erection. Erectile function is closely related to cardiovascular health. The rigidity of the erection enables a person to penetrate a partner and have sex. After ejaculation or loss of arousal, the penis can return to a flaccid state.

The penis contains no bones
The penis is not a muscle, but it does contain a few muscle fibres that help with erectile function. The penis is a complex assortment of glands, specialised tissues, and muscle fibres. It is made up of many different parts, including smooth muscle fibres around a series of blood vessels, as well as fibroelastic tissue, and some muscles at the base that help provide erectile support and propel semen through the penis during ejaculation.
The penis is not a bone, and there are no bones in the penis. The penis is near the pubic bone and the other bones that make up the pelvis, but it does not contain any bones itself. 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, known as the corpus cavernosum penis. The corpora cavernosa and corpus spongiosum are the spongy tissue segments that hold blood for erectile function. The tunica albuginea is the fibrous tissue that protects them.
The penis contains four muscles in its root: two bulbospongiosus muscles and two ischiocavernosus muscles. The bulbospongiosus muscles are associated with the bulb of the penis and help to empty the urethra of any residual semen and urine. 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 helps to maintain an erection.
The penis is definitely not a muscle, and it is not a bone. It is a unique organ with a complex structure that includes a variety of tissues, muscles, and glands.
