Female pelvic muscles Male pelvic muscles. The pelvic floor or pelvic diaphragm is an anatomical location in the human body, [1] which has an important role in urinary and anal continence, sexual function and support of the pelvic organs. [2] The pelvic floor includes muscles, both skeletal and smooth, ligaments and fascia.
The coccygeus muscle completes the pelvic floor, which is also called the pelvic diaphragm. It supports the viscera in the pelvic cavity, and surrounds the various structures that pass through it. The levator ani is the main pelvic floor muscle and contracts rhythmically during female orgasm, and painfully during vaginismus. [4]
The same human pelvis, front imaged by X-ray (top), magnetic resonance imaging (middle), and 3-dimensional computed tomography (bottom). The pelvis (pl.: pelves or pelvises) is the lower part of an anatomical trunk, [1] between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton [2] (sometimes also called bony pelvis or pelvic skeleton).
The function of the muscle is fixation of the perineal body (central tendon of perineum), support of the pelvic floor, expulsion of semen in males and last drops of urine in both sexes. [2] The deep transverse perineal muscle lies in the same plane as the urethral sphincter and formerly the two muscles were described together as the constrictor ...
The bulbospongiosus muscles (in older texts bulbocavernosus and, for female muscle, constrictor cunni) are a subgroup of the superficial muscles of the perineum. [1] They have a slightly different origin, insertion and function in males and females. In males, these muscles cover the bulb of the penis, while in females, they cover the vestibular ...

Older texts have asserted the existence of a urogenital diaphragm, also called the triangular ligament, which was described as a layer of the pelvis that separates the deep perineal sac from the upper pelvis, lying between the inferior fascia of the urogenital diaphragm (perineal membrane) and superior fascia of the urogenital diaphragm.
Kegel exercise, also known as pelvic floor exercise, involves repeatedly contracting and relaxing the muscles that form part of the pelvic floor, now sometimes colloquially referred to as the "Kegel muscles". The exercise can be performed many times a day, for several minutes at a time but takes one to three months to begin to have an effect.
