The deep transverse perineal muscle (transversus perinei profundus) lies in the perineum, a part of the pelvic floor. It arises from the inferior rami of the ischium and runs to the median plane , where it interlaces in a tendinous raphe with the other deep transverse perineal muscle of the opposite side.
The muscles surrounded by the deep perineal fascia are the bulbospongiosus, ischiocavernosus, and superficial transverse perineal. The fascia is attached laterally to the ischiopubic rami and fused anteriorly with the suspensory ligament of the penis or clitoris.
superficial transverse perinei; The perineum attaches across the gap between the inferior pubic rami bilaterally and the perineal body. This grouping of muscles constricts to close the urogenital openings. The perineum supports and functions as a sphincter at the opening of the vagina. Other structures exist below the perineum that support the ...
Contains superficial perineal muscles: transversus perinei superficialis, bulbospongiosus, ischiocavernosus: Inferior fascia of urogenital diaphragm, or perineal membrane: A membranous layer of the deep fascia: Deep perineal pouch: Contains the deep perineal muscles: transversus perinei profundus, sphincter urethrae membranaceae
The perineal membrane has two distinct portions that span the opening of the anterior pelvic outlet. [2]The ventral (anterior) portion is associated with the compressor urethra and urethrovaginal sphincter muscles (previously called deep transverse perineal muscles), and is continuous with the insertion of the arcus tendineus fascia pelvis.

For women, there is a 20.5% risk for having a surgical intervention related to stress urinary incontinence. The literature suggests that white women are at increased risk for stress urinary incontinence. [12] Though pelvic floor dysfunction is thought to more commonly affect women, 16% of men have been identified with pelvic floor dysfunction. [13]
The membranous layer of the superficial fascia of the perineum (Colles' fascia) is the deeper layer (membranous layer) of the superficial perineal fascia.It is thin, aponeurotic in structure, and of considerable strength, serving to bind down the muscles of the root of the penis.
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]
