The pubococcygeus muscle or PC muscle 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. It is part of the levator ani group of muscles.

It controls urine flow and contracts during orgasm. It aids in urinary control and childbirth.
A strong PC muscle has also been linked to a reduction in urinary incontinence and proper positioning of the baby's head during childbirth.
Kegel exercises are a set of exercises designed to strengthen and give voluntary control over the pubococcygeus muscles. They are often referred to simply as "kegels", named after their inventor Dr. Arnold Kegel.[1] These exercises also serve to contract the cremaster muscle in men, as voluntary contraction of the pubococcygeus muscle also engages the cremasteric reflex, which lifts the testicles up, although this does not occur in all men. Kegel exercise have been prescribed to help men control premature ejaculation[2] and to treat urinary incontinence in both sexes.[3][4]
The pubococcygeus arises from the back of the pubis and from the anterior part of the obturator fascia, and is directed backward almost horizontally along the side of the anal canal toward the coccyx and sacrum, to which it finds attachment.
Between the termination of the vertebral column and the anus, the two pubococcygei muscles come together and form a thick, fibromuscular layer lying on the raphé (anococcygeal raphé) formed by the iliococcygei.
The greater part of this muscle is inserted into the coccyx and into the last one or two pieces of the sacrum.
This insertion into the vertebral column is, however, not admitted by all observers.
The pubococcygeus muscle is discussed in the feature film The Oh in Ohio (2006)[5][6], which focuses on female orgasmic dysfunction[7], and includes the pubococcygeus muscle to deepen a main character's awareness of what triggers the female orgasm[8].
