The pubococcygeus (PC) muscle is a key component of the pelvic floor. It supports the pelvic organs, plays a role in urinary and fecal continence, and contributes to sexual function. Diseases or dysfunctions of this muscle can lead to a range of symptoms, affecting quality of life. In this guide, we explore the anatomy, common conditions, causes, symptoms, diagnostics, treatment options, prevention, and answers to common questions about pubococcygeus muscle diseases.
Pubococcygeus Muscle Diseases refer to any conditions that impair the normal function of the pubococcygeus muscle. These conditions can involve muscle weakness, overactivity, injury, or scarring. They may result in pelvic floor dysfunction and lead to issues such as stress urinary incontinence, pelvic pain, or pelvic organ prolapse.
Pathophysiology
Structure and Anatomy
-
Location:
The pubococcygeus muscle is part of the pelvic floor muscles. It stretches from the pubic bone to the coccyx (tailbone) and forms a supportive sling under the pelvic organs. -
Attachments:
It attaches along the inner side of the pubic bone and extends to the coccyx, working together with other pelvic muscles to stabilize the pelvic floor.
Blood Supply
- Arterial Supply:
The muscle receives blood primarily from branches of the internal pudendal artery and sometimes contributions from the inferior gluteal artery. Good blood flow is crucial for muscle health and healing.
Nerve Supply
- Innervation:
The pubococcygeus muscle is mainly innervated by the pudendal nerve and segments of the sacral spinal nerves (S2–S4). This nerve supply helps control muscle contractions and sensory feedback, which is important for continence and sexual function.
Functions
- Support of Pelvic Organs:
It holds the bladder, uterus (in women), and rectum in place. - Continence Control:
The muscle helps control the flow of urine and feces by contracting around the urethra and anus. - Sexual Function:
Contraction of the muscle is involved in sexual arousal and orgasm. - Stability:
By contributing to pelvic floor integrity, it supports overall core stability.
Types of Pubococcygeus Muscle Diseases
The conditions affecting the pubococcygeus muscle can vary in severity and presentation. Some of the common types include:
- Pelvic Floor Dysfunction:
General weakness or poor coordination of pelvic floor muscles. - Stress Urinary Incontinence:
Leakage of urine during activities that increase abdominal pressure (e.g., coughing, sneezing). - Pelvic Organ Prolapse:
Descent or dropping of pelvic organs due to weakened support. - Chronic Pelvic Pain Syndrome:
Persistent pain in the pelvic region related to muscle tension or spasms. - Myofascial Pain Syndrome:
Pain and tightness in the muscle, often with trigger points that cause referred pain. - Overactive Pelvic Floor (Hypertonicity):
Excessive muscle tension that can lead to pain and dysfunction. - Postpartum Pelvic Floor Disorders:
Muscle injury or weakening due to childbirth. - Post-Surgical Pelvic Floor Dysfunction:
Conditions developing after surgeries like hysterectomy or prostatectomy.
Common Causes of Pubococcygeus Muscle Diseases
- Childbirth:
Vaginal delivery can stretch or injure the pelvic floor. - Aging:
Muscle weakening occurs naturally over time. - Obesity:
Extra weight increases pressure on the pelvic floor. - Heavy Lifting:
Repeated strain from lifting can weaken the muscle. - Chronic Cough:
Conditions like bronchitis or asthma increase intra-abdominal pressure. - High-Impact Sports:
Activities such as running or jumping can stress the pelvic floor. - Pelvic Surgery:
Surgical interventions may inadvertently affect muscle function. - Hormonal Changes:

Some individuals may have a natural predisposition to weaker pelvic support. - Trauma or Injury:
Accidents or falls impacting the pelvic region. - Repetitive Movements:
Certain jobs or exercises involving repeated stress on the pelvic area. - High Parity:
Multiple pregnancies can contribute to pelvic floor weakening. - Neurological Disorders:
Conditions affecting nerve signals can impair muscle control. - Infections:
Pelvic infections can lead to inflammation and subsequent muscle weakness. - Poor Posture:
Chronic slouching or poor body mechanics can affect pelvic alignment. - Sedentary Lifestyle:
Lack of exercise leads to general muscle atrophy. - Excessive Strain from Lifting Heavy Objects:
Without proper technique, repeated heavy lifting can cause injury. - Connective Tissue Disorders:
Diseases that affect collagen and tissue strength. - Stress:
High stress can contribute to muscle tension and dysfunction.
