Penile erection depends on both psychogenic and mechanical stimuli. Nevertheless, in order for the body to properly react to these stimuli, an intact nervous system is essential. Therefore, erectile dysfunction is a common finding among men with SCI. [1]
This condition prevents the full retraction of the foreskin with or without an erection. [1] It is a simple and normally painless procedure that is performed in a urologist's office. First the physician applies a local anesthetic, such as lidocaine/prilocaine cream on the frenulum and surrounding area. If the patient retains any feeling there ...
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.
Likewise, although a man's ability to get a psychogenic erection when mentally aroused may be impaired after a higher-level SCI, he may still be able to get a reflex or "spontaneous" erection. [ 21 ] [ 27 ] These erections may result in the absence of psychological arousal when the penis is touched or brushed, e.g. by clothing, [ 43 ] but they ...
The goal of nocturnal penile tumescence testing is to determine whether one can experience an erection while sleeping after reporting that they are unable to experience an erection while awake. On average, one has 3–5 episodes of NPT each night, and each episode lasts 30–60 minutes, although the duration is reduced with advanced age. [ 16 ]
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.
After maximum erection is obtained, the subject’s penis subsequently becomes flaccid again (3:55). Also visible in this demonstration are the tightening of the subject’s scrotum and the elevating of his testicles during arousal. This conscious process can be compared with the same subject's unconscious nocturnal erection process.
Because of the significant skeletal muscle contractions it causes, electroejaculation is not used in stallions — except in rare cases, under general anesthesia. [citation needed] In humans, electroejaculation is usually carried out under a general anesthetic. [1] An electric probe is inserted into the rectum adjacent to the prostate gland ...
