What You'll Learn
The penis is not a muscle
Despite the common misconception, the penis is not a muscle. While the penis does contain muscle fibres and muscles at its base that help with erectile support, these muscles are not the primary component of the penis. Instead, the penis is a complex structure composed of various tissues, blood vessels, and nerves.
The penis is made up of three main parts: the root, the body, and the glans. The root, located in the pelvic floor, contains erectile tissues and muscles, including the ischiocavernosus and bulbospongiosus muscles. These muscles play a crucial role in achieving and maintaining erections by forcing blood into the corpora cavernosa, which are two cylinders of erectile tissue in the body of the penis. The body of the penis is suspended from the pubic symphysis and is composed of three cylinders of erectile tissue: two corpora cavernosa and one corpus spongiosum.
The glans, the most distal part of the penis, is formed by the expansion of the corpus spongiosum. It contains the opening of the urethra, which allows for the passage of urine and semen. While the penis does not contain any bones, it is surrounded by bones, including the pubic bone and the pelvic bones. These bones provide protection and structural support to the internal reproductive system, including the penis.
During sexual arousal, the penis fills with blood, causing an erection. This process is facilitated by the muscles and muscle fibres within and around the penis, as well as elastic tissues and fibres that help maintain the erection. However, it is important to note that the size and firmness of an erection can vary, and there is no direct correlation between the size of a flaccid penis and its length when erect. Additionally, the sensitivity of the penis may decrease with age, and issues with achieving and maintaining erections can become more common.
While nicknames like "boner" and "love muscle" are commonly used, they are not anatomically accurate. The penis is a complex organ that relies on the coordination of various structures and systems to function properly. Understanding the true anatomy of the penis can help dispel misconceptions and promote better sexual and reproductive health.

The penis contains muscle fibres
The penis is not a muscle, but it does contain muscle fibres. It is part of the male reproductive system and is made up of a mix of tissues, glands, and muscle fibres that work together to create an erection. The penis is not a bone either, despite nicknames like "boner" that may suggest otherwise.
The penis contains soft, spongy tissue, muscles, fibrous tissue, veins, arteries, and the urethra. These components allow the penis to perform its functions, including erection, ejaculation, and urination. The penis is designed with the right amount of flexibility to enable sexual intercourse, reproduction, 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, forcing blood into the corpora cavernosa to help maintain an erection. The bulbospongiosus muscle, associated with the bulb of the penis, contracts to empty the urethra of residual semen and urine and aids in maintaining erection by increasing pressure in the bulb.
The body of the penis, located between the root and the glans, is composed of three cylinders of erectile tissue: two corpora cavernosa and the corpus spongiosum. The corpora cavernosa contain spongy tissue and arteries that fill with blood during arousal, causing the penis to swell and stiffen. The corpus spongiosum, which is formed by the bulb of the penis, contains the urethra and expands to form the glans penis.
The penis relies on muscles both internally and externally to function. The ischiocavernosus, bulbospongiosus, and smooth muscle tissue within the penis work together to achieve and maintain an erection. These muscles help to seal off blood during an erection, force semen out during ejaculation, and relax to allow the penis to return to a flaccid state.

Muscles are involved in producing an erection
While the penis is not a muscle, it does contain some muscle fibres that help with erectile function. The ischiocavernosus muscles, bulbospongiosus muscle, and the smooth muscle tissue within the penis all work together to make an erection hard and steady. 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 and 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 ischiocavernosus muscle forces blood from the cavernous spaces in the crura into the corpora cavernosa, providing additional rigidity during the rigid erection phase. The bulbospongiosus muscle contracts to empty the spongy urethra of any residual semen and urine, and the anterior fibres also aid in maintaining an erection by increasing the pressure in the bulb of the penis.
The activation of the parasympathetic nerves leads to reduced intracellular calcium levels, causing cavernosal and arterial smooth muscle relaxation. This effect increases blood flow by approximately 20 to 40 times the expanding sinusoids of the corpora cavernosa. As these sinusoids enlarge, the outer portions of the corpora near the tunica albuginea start to occlude venous outflow. The pressure in the corpora cavernosa will rise to averages around 100 mmHg in most men. The pressure in the corpus spongiosum is approximately one-third of that found in the corpora cavernosa.
The penis is not a muscle, but it does have muscles nearby that make movement possible. The muscles of the perineal area and pelvic floor, as well as the crura and suspensory ligament, are internal structures that assist in urinary and sexual function. Kegel exercises can help improve cock control by strengthening the pubococcygeal (PC) muscles, which work as a sling to keep pelvic organs in place. They also help control bladder and sexual function.

Muscles help the penis return to a flaccid state
The penis is not a muscle, but it does contain some muscle fibres and is surrounded by muscles that play a crucial role in its function. The penis is made up of a mix of tissues, glands, and muscle fibres that work together to achieve an erection. While the penis itself is not a muscle, the muscles in and around it are essential for it to transition from a flaccid to an erect state and back.
The penis contains smooth muscle fibres around an extensive series of blood vessels. These muscles, along with fibrous elastic tissue, help support the penis as it transitions from a flaccid to an erect state. When a person is aroused, blood rushes to the penis, and these muscles, along with fibrous elastic tissue, collagen, and erectile tissue, help the penis stiffen and harden as it fills with blood.
The ischiocavernosus and bulbospongiosus muscles are located in the root of the penis. The bulbospongiosus muscle is associated with the bulb of the penis and helps to empty the urethra of residual semen and urine. It also aids in maintaining an erection by increasing the pressure in the bulb of the penis. The ischiocavernosus muscle surrounds the left and right crura of the penis and helps maintain an erection by forcing blood from the cavernous spaces in the crura into the corpora cavernosa.
The muscles in and around the penis work together to achieve and maintain an erection. However, they also play a role in returning the penis to a flaccid state. After ejaculation or loss of arousal, the muscles in the penis relax, allowing the penis to return to its flaccid state. This relaxation of muscles results in a reduction in blood flow to the penis, causing it to soften and return to its original size.
While the penis is not a muscle itself, the muscles associated with it are crucial for its function and ability to transition between states. These muscles work in conjunction with other tissues and structures in the penis to enable it to perform its reproductive and urinary functions effectively.

Muscles can be strengthened with Kegel exercises
While the penis is not a muscle, it does contain a few muscle fibres that help with erectile function. These muscles work together to make your erection hard and steady its erect direction for sexual penetration.
Kegel exercises are a great way to strengthen these muscles and improve your overall penis health. Kegels are commonly known for their benefits to women, but they can be extremely advantageous to men as well. These exercises strengthen the pelvic floor muscles, which support bladder and bowel control. They also help control sexual function by aiding in the control of blood flow to the penis, creating an erection and controlling ejaculation.
To perform Kegel exercises, you must identify the correct muscles to engage. These are the pelvic floor muscles, which can be activated by imagining that you're trying to stop yourself from urinating or passing gas. Once you've located these muscles, squeeze them as if you're trying to stop urine from coming out, hold for five seconds, and then release. Repeat this step eight to ten times, and then do three to five sets. As you become more comfortable with the exercises, you can gradually increase the duration of the squeeze and hold, as well as the number of repetitions or sets.
It's important to keep a few things in mind while performing Kegel exercises. Firstly, don't push down; instead, focus on squeezing your pelvic muscles together tightly as if you're trying to lift something up. Secondly, try to keep your stomach muscles relaxed throughout the exercise. Lastly, remember to relax your pelvic floor muscles between each squeeze.
By incorporating Kegel exercises into your routine and consistently practising them, you can strengthen the muscles associated with the penis and improve your overall sexual function, bladder control, and ejaculatory control.
