The dorsal nerve of the penis is the deepest of three divisions of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.
The cavernous nerves are post-ganglionic parasympathetic nerves that facilitate penile erection and clitoral erection. [1] They arise from cell bodies in the inferior hypogastric plexus where they receive the pre-ganglionic pelvic splanchnic nerves (S2-S4). In the penis, there are both lesser cavernous nerves and a greater cavernous nerve.
The pudendal nerve is the main nerve of the perineum. [1]: 274 It is a mixed (motor and sensory) nerve and also conveys sympathetic autonomic fibers.It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well as the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter.
The pelvic splanchnic nerves contribute to the innervation of the pelvic and genital organs. [2] The nerves regulate the emptying of the urinary bladder, control opening and closing of the internal urethral sphincter, influence motility in the rectum as well as sexual functions like erection.
An erection (clinically: penile erection or penile tumescence) is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal, sexual attraction or libido, although erections can also be spontaneous.

The nerves composing it are of large size. They are distributed to the prostate seminal vesicle and the corpora cavernosa of the penis and urethra . 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 ...
The nerves that control one's ability to have a reflex erection are located in the sacral nerves (S2-S4) of the spinal cord. [8] Evidence supporting the possibility that a full bladder can stimulate an erection has existed for some time and is characterized as a 'reflex erection'. [9] A full bladder is known to mildly stimulate nerves in the ...
