Prostatic plexus can refer to:

Prostatic plexus (nervous)

Injury to the prostatic plexus (during prostatic resection for example) is highly likely to cause erectile dysfunction.

It is the source for the middle rectal plexus, vesical plexus, prostatic plexus, and uterovaginal plexus.

The prostatic veins form a well-marked prostatic plexus which lies partly in the fascial sheath of the prostate and partly between the sheath and the prostatic capsule.

The nerves supplying the corpora cavernosa consist of two sets, the lesser and greater cavernous nerves, which arise from the forepart of the prostatic plexus, and, after joining with branches from the pudendal nerve, pass forward beneath the pubic arch.
