The spongiosum contains the urethra and is contiguous with the glans distally.
This study takes a topical approach to this subject, which throughout time, has encountered significant barriers in regards to communication, expressing sexual dysfunctions, and their manifestations between the two partners of the married couple.

The arterial supply to the penis is from the four terminal branches of the paired penile arteries, which are themselves branches of the internal pudendal arteries. The external iliac, obturator, vesical, and femoral arteries provide accessory arterial supply to the penile artery in some cases.
Venous outflow originates from postcavernous venules that coalesce to form emissary veins. These veins empty into the cavernous vein, erectile dysfunction deep dorsal vein, and the negi genitale pe penis dorsal vein depending on their origin within the penis.

Efferent innervation is from parasympathetic, sympathetic, and somatic sources. Somatosensory afferents course from the penis to central sites.

The maintenance of penile flaccidity and the erectile response are controlled via intercommunicating supraspinal and spinal reflex pathways. During the flaccid state, antierectile neural input, primarily via sympathetic efferents, acts to limit blood flow to the penis to a quantity sufficient to meet physiologic needs but insufficient for erection.
Following either physical or psychological sexual stimulation proerectile neural signals are sent to the penis primarily via parasympathetic tracts. This input initiates the erectile response via neurotransmitter release onto postsynaptic smooth muscle cells within the corporal bodies.
Nitric Oxide NO is the main proerectile neurotransmitter. This relaxation allows for increased blood flow and subsequent corporal engorgement with increasing penile rigidity. As the corpora become engorged, the emissary veins are compressed by within the tunica albuginea limiting venous outflow.
The increased arterial inflow and erectile dysfunction venous outflow increases intracorporal pressure and leads to erection.
