Despite the penis being commonly referred to as a 'love muscle', it is not a muscle. It is a complex organ made up of erectile tissue, connective tissue, and blood vessels. Erections occur when the muscles around the corpus cavernosum relax, allowing blood to flow and engorge the organ. The corpora cavernosa, or erectile tissue, is responsible for the majority of the penis's rigidity during an erection. The bulbospongiosus and ischiocavernosus muscles also play a role in maintaining erections by compressing the veins to prevent them from draining blood from the corpora cavernosa.

What You'll Learn
The penis is not a muscle
Despite the popular moniker "love muscle", the penis is not a muscle. It is made of spongy tissue that fills with blood when a person gets an erection. The corpus cavernosum contains this spongy tissue and arteries that run along its middle. When the muscles surrounding the corpus cavernosum relax, blood flows into the open spaces, creating pressure that causes the penis to stiffen and swell.
While the penis is not a muscle, it does contain a few muscle fibres that manage the blood that makes up erections. The ischiocavernosus, bulbospongiosus, and bulbocavernosus muscles are integral for maintaining an erection. Rhythmic contractions of the bulbospongiosus muscle during ejaculation force blood from the bulb, creating a pressure wave that expels semen from the urethra.
The penis can be flexed, stretched, and moved due to the presence of these muscles. The urethralis muscle, for example, surrounds the pelvic portion of the urethra and the bulbourethral glands. Contractions of this muscle release seminal fluid during ejaculation and empty the bladder during urination.
The penis is also surrounded by other muscles that enable movement, such as penetration and urination. Kegel exercises can strengthen these muscles, improving bladder control and sexual function.
Erections are a result of the parasympathetic nervous system (PSNS) and are an involuntary response to arousing stimuli. When a person is aroused, the smooth muscles in the arteries relax and open up, allowing blood to flow into the penis and creating a hard erection.

The penis is not a bone
The penis is often referred to as the "love muscle", which is why many people assume it is a muscle. However, this is a misconception. While the penis is not a muscle, certain muscles are involved in the process of achieving and maintaining an erection. For example, during sexual arousal, the brain signals the release of nitric oxide, which causes the muscles within the penis to relax and allow blood to flow and engorge the organ, resulting in 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 corpus cavernosum contains spongy tissue and arteries that run along its middle. 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 penis is capable of fluctuating between a spongy softness and a bony rigidity due to its unique fibroskeleton design. However, despite its rigidity, the penis does not contain any bones.

Muscles are involved in achieving an erection
While the penis is not a muscle, certain muscles are involved in the process of achieving and maintaining an erection. The penis is a complex organ made up of erectile tissues, connective tissues, and blood vessels. It is composed of a network of blood vessels and smooth muscle, allowing it to expand and accommodate the increased blood flow that occurs during an erection.
The muscles involved in achieving an erection include the ischiocavernosus and bulbocavernosus muscles, which compress the spongiosum and penile veins, resulting in further engorgement and increased pressure in the glans and spongiosum. The bulbospongiosus muscle covers the CSP and extends nearly the entire length of the penis. It sends transversely directed fibres from the edges of the urethral groove to meet at a median septum. Rhythmic contractions of this muscle during ejaculation force blood from the bulb, creating a pressure wave that forcefully expels semen from the urethra.
The ischiourethral muscles extend from the ventral surface of the ischium and crura, passing around the ischial arch into the pelvic cavity, and ending at the ventral layer of the urethralis muscle. They may assist erection by compressing the dorsal veins of the penis. The urethralis muscle surrounds the pelvic portion of the urethra and the bulbourethral glands, and its contractions force the release of seminal fluid during ejaculation and the emptying of urine during urination.
During sexual arousal, the brain signals the release of nitric oxide, which causes the muscles within the penis to relax, allowing blood to flow and engorge the organ, resulting in an erection. The corpora cavernosa, or erectile tissue, is responsible for most of the penis's rigidity during an erection. The smooth muscles in the arteries relax, opening them up and allowing the penis to fill with blood and achieve a hard erection.

Erection is a reflex
Despite the nickname "love muscle", the penis is not a muscle. It is made of spongy tissue that fills with blood when a person gets an erection. Erections occur when the muscles around the corpus cavernosum relax, allowing blood to flow into its open spaces. This pressure causes the penis to swell and stiffen.
The parasympathetic nervous system (PSNS) is responsible for bringing about an erection. The PSNS is the opposite of the sympathetic nervous system (SNS), which controls the fight-or-flight response. While the SNS is activated when a person is anxious, the PSNS kicks in when they are relaxed, dilating the arteries in the penis and encouraging blood flow.
The ischiocavernosus and bulbospongiosus muscles are also involved in maintaining an erection. The ischiocavernosus muscle is involved in the flip movement of the penis during erection, while the bulbospongiosus muscle is involved in the cup movement, or substantial engorgement of the glans penis.

The penis is a complex organ
The penis is composed of three cylinders: two corpora cavernosa and one corpus spongiosum. These tissues fill with blood during arousal, leading to an erection. The corpora cavernosa is responsible for most of the penis's rigidity during an erection. The corpus spongiosum surrounds the urethra and helps maintain the penis's shape and structure.
The bulbospongiosus and ischiocavernosus muscles are essential for maintaining an erection. They compress the veins to prevent blood from draining from the corpora cavernosa, resulting in further engorgement and increased pressure. The urethralis muscle surrounds the pelvic portion of the urethra and is responsible for releasing seminal fluid during ejaculation and emptying the bladder during urination.
The penis has two main functions: intercourse and urination. For intercourse, the penis must be erect. Erection occurs when the brain signals the release of nitric oxide, causing the muscles within the penis to relax and allowing blood to flow and engorge the organ. The parasympathetic nervous system (PSNS) is responsible for bringing about an erection, while the sympathetic nervous system (SNS) controls the fight-or-flight response, which can interfere with achieving or maintaining an erection.

Frequently asked questions
No, a boner is not a muscle. The penis is not a muscle or a bone but rather a complex organ made up of erectile tissues, connective tissues, and blood vessels.
An erection is an involuntary response to erotic stimuli. When a person is aroused, the muscles around the corpus cavernosum relax, allowing blood to flow and engorge the penis, resulting in an erection.
The corpus cavernosum is one of the three cylinders that make up the penis. It contains spongy tissue and arteries that run along its middle.
The other two cylinders are the corpus spongiosum and the urethra.
To improve erection strength, you can try Kegel exercises. These exercises strengthen the pubococcygeal (PC) muscles, which can help improve sexual function.
