They continue into the dorsal aspect of the shaft forming the two corpora cavernosa that are separated by the septum of the penis. [5] During arousal, the root and the corpora cavernosa engorge with blood and become rigid . Meanwhile, the corpus spongiosum remains pliable making the urethra a viable channel for semen during ejaculation. [6]
In humans, the glans is located over the distal ends of the corpora cavernosa and is a continuation of the corpus spongiosum of the penis. At the summit appears the urinary meatus and at the base forms the corona glandis. An elastic band of tissue, known as the frenulum, runs on its ventral surface.
A penile implant is an implanted device intended for the treatment of erectile dysfunction, Peyronie's disease, ischemic priapism, deformity and any traumatic injury of the penis, and for phalloplasty or metoidioplasty, including in gender-affirming surgery. Men also opt for penile implants for aesthetic purposes.
The corpora cavernosa are innervated by lesser and greater cavernous nerves and form most of the penis containing blood vessels that fill with blood to help make an erection. [8] The crura are the proximal parts of the corpora cavernosa. The corpus spongiosum is an erectile tissue surrounding the urethra.
The function of the corpus spongiosum in erection is to prevent the urethra from pinching closed, thereby maintaining the urethra as a viable channel for ejaculation. To do this, the corpus spongiosum remains pliable during erection while the corpora cavernosa penis become engorged with blood.
An inflatable penile implant inserted into corpus cavernosum of the penis. Phalloplasty requires an implanted penile prosthesis to achieve an erection. Penile prostheses are implanted devices intended to restore the erectile rigidity in cisgender men and to build a neophallus (new penis) in transgender men. Penile implants have been used in ...

The ligament attaches by its apex onto the symphysis pubis and linea alba, and by its base onto the dorsal and lateral aspects of the corpora cavernosa penis. [1]The midline lamina splits inferiorly/distally to attach onto each corpus cavernosus penis lateral to the groove of the deep dorsal vein of penis, whereas each lateral lamina attaches distally onto the lateral aspect of the ...
