It is formed by the folded lower border of the aponeurosis of the external abdominal oblique muscle as is extends between the ASIS and the pubic tubercle.
It includes the deep transverse perineal muscle which runs from the ischial ramus to the central perineal tendon and is innervated by the perineal branch of the pudendal nerve.

 Fibromyalgia Information for YourUrologist
Often, in cases of irritable bladder and bowel, the lower internal oblique muscle and possibly lower rectus abdominus are involved.
The anterior and middle fibers of the bulbospongiosus and ischiocavernosus muscles contribute to erection by reflex and voluntary contraction that compresses the erectile tissue of the bulb of the penis and also its dorsal vein.
Contraction of the ischiocavernosus muscle maintains and enhances penile erection by retarding the return of blood through the crus penis.

 Heart and Metabolism
The nitric oxide penetrates the smooth muscle cell, where it stimulates the enzyme guanylate cyclase to produce cyclic guanosine 3′5′-monophosphate (cGMP), which is the active second messenger within the cell.
As the skeletal muscle fatigues, there is a decrease in the intracavernosal pressure back to those values seen during the full erection phase, allowing circulation to return to the cavernosal tissue.
Parasympathetic stimulation leads to smooth muscle relaxation that results in an active increase in arterial inflow, active relaxation of the cavernosal sinusoids, and a passive reduction in venous outflow (the veno-occlusive mechanism).

Contraction of the smooth muscle in the bladder wall and the involuntary sphincter of the bladder is regulated by parasympathetic nerves (pelvic splanchnics arising from S2-4).
The major contents of the superficial pouch are columns of erectile tissue and thin sheets of muscle covering the erectile tissue and the posterior portion of the perineal membrane, nerves supplying these muscles and the overlying skin (perineal branches of the pudendal nerve), and blood vessels supplying the region (branches of internal pudendal vessels).

 BioMed Central | Full text | Pudendal nerve decompression in perineology : a case series
Caudally, at the level of the anus, the nerve gives medially the inferior rectal nerves (usually two branches) which innervate the anal sphincter (and probably the pubo-rectalis) and the skin of the posterior perineum and anterolaterally the transversus perinei branch (for this muscle, for the ischiocavernosus muscle and maybe for the urethral sphincter) [4].

 Prostatitis: Myofascial Pain Syndrome?
It is not surprising, therefore, that chronic pelvic floor dysfunction is often combined with smooth muscle dysfunction of the lower urinary tract, and both may be maintained by upregulated sacral reflexes.
Given the association of muscle dysfunction and nociception, chronic pelvic pain in some men could be considered a myofascial pain condition that is caused and maintained by central neurogenic mechanisms.

 Electromyography of Male Rat Perineal Musculature during Copulatory Behavior
Electromyogram (EMG) recordings were made from the bulbospongiosus (BS) and ischiocavernosus (IC) muscles of the awake male rat in order to evaluate the roles played by these muscles in the implementation of penile intromission during a copulatory encounter.
On EMGs recorded from the IC muscle, the initial low-amplitude phase at the initiation of each behavioral component was distinguished from the late high-amplitude phase whenever the male accomplished mounting or intromission.
In the BS muscle, however, the spectra of the two phases differed at a specific range of 400-600 Hz.
