Home > Pubococcygeus muscle
The pubococcygeus muscle or PC muscle is an important muscle in the human body. It is a hammock-like muscle, found in both sexes, that stretches from the pubic bone to the coccyx (tail bone) forming the floor of the pelvic cavity and supporting the pelvic organs . Also known as the PC muscle, it controls urine flow and contracts during orgasm. It surrounds the rectum, the vagina (in women) and bladder openings. It aids in urinary control, and childbirth. A well-toned pubococcygeus muscle can enhance sex and orgasm in both sexes. Kegel exercises are a set of exercises designed to strengthen and give voluntary control over the pubococcygeus muscles. These exercises are often referred to simply as "kegels."
A strong pc muscle has also been attributed to a reduction in urinary incontinence and proper positioning of the baby's head during childbirth.
