The pubococcygeus (PC) muscle is a critical part of the pelvic floor. It plays a role in supporting pelvic organs, controlling urine flow, and contributing to sexual function. When the PC muscle becomes hypertrophied (enlarged), it may result in discomfort, altered function, or even pelvic pain. Understanding this condition—from its underlying anatomy to treatment options—can help individuals recognize symptoms early and seek appropriate care.
Pubococcygeus muscle hypertrophy is a condition where the PC muscle grows larger than its normal size. This may occur as a result of:
- Overuse or repetitive strengthening exercises (for example, frequent or excessive pelvic floor exercises)
- Compensatory changes due to injury or weakness in other pelvic muscles
- Certain medical conditions or hormonal influences
Hypertrophy of the PC muscle might lead to symptoms such as pelvic pain, urinary difficulties, or sexual dysfunction.
Pathophysiology:
Anatomy and Structure
-
Location:
The pubococcygeus muscle is a key component of the pelvic floor. It stretches from the pubic bone (the front of the pelvis) to the coccyx (tailbone) and forms a supportive sling around the pelvic organs. -
Shape and Composition:
It is a part of the levator ani muscle group. The muscle fibers are arranged in a way that they can contract and relax, supporting the bladder, uterus (in women), and rectum.
Blood Supply
- Main Vessels:
The PC muscle receives blood from branches of the internal pudendal artery and other small pelvic vessels. Adequate blood supply ensures that the muscle gets the oxygen and nutrients required for both everyday function and recovery from strain.
Nerve Supply
- Innervation:
The pelvic floor muscles, including the PC muscle, are mainly innervated by the pudendal nerve and nerves from the sacral plexus (S2–S4). These nerves control the contraction and relaxation of the muscle and help transmit pain signals if the muscle is overworked or injured.
Functions
The pubococcygeus muscle plays several important roles:
- Support of Pelvic Organs:
It helps support the bladder, uterus, and rectum, preventing conditions like prolapse. - Control of Urinary and Fecal Continence:
The muscle contributes to the control of the urinary sphincter, helping prevent incontinence. - Sexual Function:
In both men and women, the PC muscle assists in sexual performance by controlling blood flow and contributing to orgasm. - Stabilization of the Core:
It also provides stability to the pelvic region, which supports the lower back and contributes to posture.
Types of Pubococcygeus Muscle Hypertrophy
While hypertrophy is typically described by its severity, it may be classified in a few different ways:
-
Physiological Hypertrophy
- Description: Occurs as a normal response to exercise, such as during targeted pelvic floor training (e.g., Kegel exercises).
- Impact: Often beneficial, as it strengthens pelvic support, but if overdone, it may lead to tightness or discomfort.
-
Pathological Hypertrophy
- Description: Abnormal muscle enlargement due to chronic strain, injury, or hormonal changes.
- Impact: Can cause pelvic pain, urinary issues, or sexual dysfunction.
-
Compensatory Hypertrophy
- Description: Occurs when other pelvic floor muscles are weakened or injured, and the PC muscle compensates by overworking.
- Impact: This type of hypertrophy is often associated with imbalances and may lead to discomfort or dysfunction.
Common Causes of Pubococcygeus Muscle Hypertrophy
- Excessive Kegel Exercises:
Overdoing pelvic floor exercises without proper technique. - Chronic Pelvic Floor Tension:
Ongoing stress or tension in the pelvic region. - Improper Exercise Form:

Improving posture, managing stress, balancing exercise routines, and avoiding activities that overstrain the pelvic floor are beneficial.
13. Is surgery ever required?
Surgery is rarely needed and is usually reserved for severe cases or when other treatments have not helped.
14. How long does it take to recover?
Recovery time varies; mild cases may improve within weeks, while chronic or severe hypertrophy may take longer with proper treatment.
15. Can preventive measures stop pubococcygeus muscle hypertrophy?
Yes, by using correct exercise techniques, maintaining a balanced workout routine, and managing stress, you can reduce the risk of developing hypertrophy.
