Prostatic plexus

The prostatic plexus arises from the inferior portion of the pelvic plexus. It is located in the prostate's fascial shell, and consists of a fairly big bundle of nerves. The nerves of the plexus are distributed to the corpora cavernose of the urethra and penis, and also to the vesiculae seminales of the prostate. Two sets of nerves supply the corpora cavernosa, which are known as the greater and lesser cavernous nerves. They originate from the anterior part of the plexus. The nerves travel forward, below the public arch, once they attach with the pudendal nerve branches. The nervous plexus supports the function of penile erection. Therefore, any injury or damage caused to it may result in erectile dysfunction of the penis. During surgery of the prostate, the surgeon must be cautious to maintain the integrity of the fascial shell to avoid any risk to the plexus. The venous prostatic plexus constitutes prostatic veins that are located partly in the prostate's fascial shell, as well as partly between the prostatic capsule and the shell. It connects with the vesical and pudendal plexuses.
