By Dr. Zarina Vitebsky, DPT, MSPT, PRPC, TPS, LPF, DN on 10/29/2023

Overview

The penis is a male reproductive organ that is responsible for sexual function and urination. It is composed of three main parts: the root, the shaft, and the glans. The root is the base of the penis, which attaches to the pelvic bones. The shaft is the main body of the penis, and the glans is the rounded tip. The penis also contains three chambers of spongy tissue that fill with blood during an erection.

Importance of Understanding Penis Anatomy

Understanding penis anatomy is crucial for overall sexual health and function. It allows individuals to identify any potential issues or dysfunctions and seek appropriate treatment. It also helps in communication with healthcare professionals, as well as partners, about any concerns or problems related to the penis.

Introduction to Potential Dysfunctions

There are various potential dysfunctions that can affect the penis, including erectile dysfunction, premature ejaculation, and Peyronie's disease. Erectile dysfunction is the inability to achieve or maintain an erection, while premature ejaculation is the inability to control ejaculation. Peyronie's disease is a condition where scar tissue forms in the penis, causing it to curve during an erection.

Overview of How Pelvic Floor Physical Therapy (PFPT) Can Treat Dysfunctions

Pelvic floor physical therapy (PFPT) is a specialized form of physical therapy that focuses on the muscles, ligaments, and tissues in the pelvic floor. It can be used to treat various dysfunctions related to the penis, such as erectile dysfunction, premature ejaculation, and Peyronie's disease. PFPT can help improve blood flow, strengthen pelvic floor muscles, and address any underlying issues that may be causing the dysfunction.

Penis Anatomy

External Structures

The external structures of the penis include the shaft, glans, and foreskin. The shaft is the main part of the penis and is made up of three cylindrical columns of tissue called the corpora cavernosa. The glans, also known as the head of the penis, is the sensitive, rounded end of the penis. The foreskin is a retractable fold of skin that covers the glans in uncircumcised males.

Internal Structures

The internal structures of the penis include the corpora cavernosa, corpus spongiosum, and urethra. The corpora cavernosa are two chambers that run along the length of the penis and are responsible for the majority of the penis's rigidity during an erection. The corpus spongiosum is a smaller chamber that surrounds the urethra, which is the tube that carries urine and semen out of the body.

Blood Supply and Nerve Innervation

The penis receives its blood supply from the internal pudendal artery, which branches off from the internal iliac artery. The nerve innervation of the penis comes from the pudendal nerve, which is responsible for sensation and motor control of the pelvic floor muscles.

Role of Pelvic Floor Muscles in Penis Function

The pelvic floor muscles play a crucial role in penis function, including maintaining erections, controlling ejaculation, and supporting the bladder and bowel. Dysfunction in these muscles can lead to issues such as erectile dysfunction, premature ejaculation, and urinary incontinence. Pelvic floor physical therapy (PFPT) can help treat these dysfunctions by strengthening and relaxing the pelvic floor muscles through exercises and manual therapy techniques.

Potential Dysfunctions

Erectile Dysfunction

Erectile dysfunction (ED) is the inability to achieve or maintain an erection sufficient for sexual activity. It can be caused by various factors such as physical conditions (e.g. diabetes, heart disease), psychological factors (e.g. stress, anxiety), and lifestyle choices (e.g. smoking, excessive alcohol consumption).

ED can have a significant impact on sexual function and relationships. It can lead to feelings of inadequacy, frustration, and low self-esteem for the individual experiencing it. It can also cause strain and tension in intimate relationships.

Psychological factors can also play a role in ED. Performance anxiety, relationship issues, and past traumas can all contribute to difficulties with achieving or maintaining an erection.

Premature Ejaculation

Premature ejaculation (PE) is a common sexual dysfunction where a man ejaculates sooner than he or his partner would like during sexual activity. It can be caused by physical factors such as hormonal imbalances or inflammation of the prostate, as well as psychological factors such as anxiety, guilt, or relationship issues.

PE can have a significant impact on sexual function and relationships. It can lead to feelings of frustration, embarrassment, and shame for the individual experiencing it. It can also cause strain and tension in intimate relationships.

Psychological factors can also play a role in PE. Performance anxiety, relationship issues, and past traumas can all contribute to difficulties with controlling ejaculation.

Peyronie's Disease

Peyronie's disease is a condition where scar tissue forms in the penis, causing it to curve or bend during an erection. It can be caused by trauma to the penis, genetics, or underlying medical conditions such as diabetes or high blood pressure.

Peyronie's disease can have a significant impact on sexual function and relationships. It can cause pain during erections, difficulty with penetration, and feelings of embarrassment or shame. It can also lead to strain and tension in intimate relationships.

Psychological factors can also play a role in Peyronie's disease. The physical changes in the penis can cause feelings of insecurity and low self-esteem, which can affect sexual function and relationships.

Other Dysfunctions

In addition to the above dysfunctions, there are other potential dysfunctions that can affect the penis. These include priapism, a prolonged and painful erection, and penile fracture, a rare but serious injury that occurs when the erect penis is bent forcefully.

Both priapism and penile fracture can have a significant impact on sexual function and relationships. They can cause physical pain and discomfort, as well as psychological distress and strain in intimate relationships.

Role of Pelvic Floor Physical Therapy

Definition and Goals of PFPT

Pelvic Floor Physical Therapy (PFPT) is a specialized form of physical therapy that focuses on the muscles, ligaments, and tissues of the pelvic floor. The pelvic floor is a group of muscles that support the pelvic organs, including the bladder, rectum, and penis. The main goal of PFPT is to improve the function and strength of these muscles to alleviate symptoms and improve overall quality of life.

How PFPT Can Help with Penis Dysfunctions

Penis dysfunctions, such as erectile dysfunction, premature ejaculation, and pain during intercourse, can be caused by a variety of factors, including pelvic floor muscle dysfunction. PFPT can help by addressing any underlying issues with the pelvic floor muscles, which may be contributing to these dysfunctions. By improving the strength and function of these muscles, PFPT can help improve sexual function and alleviate symptoms.

Techniques Used in PFPT for Penis Dysfunctions

There are several techniques used in PFPT to address penis dysfunctions:

1. Manual Therapy: This involves hands-on techniques to release tension and improve mobility in the pelvic floor muscles. This can include massage, stretching, and trigger point release.

2. Biofeedback: This technique uses sensors to measure muscle activity and provides visual or auditory feedback to help patients learn how to relax and contract their pelvic floor muscles properly.

3. Therapeutic Exercises: Specific exercises are prescribed to strengthen and improve the function of the pelvic floor muscles. These may include Kegels, squats, and other targeted movements.

Benefits of PFPT for Penis Dysfunctions

PFPT can offer numerous benefits for those experiencing penis dysfunctions:

• Improved sexual function and satisfaction

• Reduced pain and discomfort during intercourse

• Increased bladder and bowel control

• Improved overall pelvic floor muscle function and strength

• Reduced risk of future pelvic floor issues

Treatment of Specific Dysfunctions

Erectile Dysfunction

Erectile dysfunction is a common condition where a man is unable to achieve or maintain an erection sufficient for sexual intercourse. Pelvic floor physical therapy (PFPT) can be an effective treatment for this dysfunction. PFPT techniques such as pelvic floor muscle exercises, biofeedback, and manual therapy can help improve blood flow and muscle function in the pelvic region, leading to improved erectile function.

Expected outcomes of PFPT for erectile dysfunction may include increased ability to achieve and maintain an erection, improved sexual satisfaction, and increased confidence and self-esteem. A case study from our clinic of a 45-year-old man with erectile dysfunction showed significant improvement in erectile function after 12 weeks of PFPT, with the patient reporting increased frequency and quality of erections.

Premature Ejaculation

Premature ejaculation is a common sexual dysfunction where a man ejaculates too quickly during sexual activity, often before he or his partner is satisfied. PFPT can be an effective treatment for this condition by addressing underlying pelvic floor muscle dysfunction and improving control over ejaculation.

PFPT techniques used for premature ejaculation may include pelvic floor muscle exercises, relaxation techniques, and behavioral therapy. Expected outcomes of PFPT for premature ejaculation may include improved control over ejaculation, increased sexual satisfaction, and improved relationship dynamics.

Peyronie's Disease

Peyronie's disease is a condition where scar tissue forms in the penis, causing it to curve or bend during erections. This can lead to pain, difficulty with intercourse, and psychological distress. PFPT can be an effective treatment for Peyronie's disease by addressing pelvic floor muscle dysfunction and improving penile blood flow.

PFPT techniques used for Peyronie's disease may include pelvic floor muscle exercises, manual therapy, and stretching techniques. Expected outcomes of PFPT for this condition may include reduced pain, improved penile curvature, and improved sexual function.

Other Dysfunctions

In addition to the above-mentioned dysfunctions, PFPT can also be beneficial for other pelvic floor-related dysfunctions such as urinary incontinence, pelvic pain, and post-prostatectomy dysfunction. PFPT techniques used for these conditions may include pelvic floor muscle exercises, biofeedback, and manual therapy.

Expected outcomes of PFPT for these dysfunctions may include improved bladder control, reduced pain, and improved sexual function.
