Classification of Sexual Dysfunction in Male
Sexual Dysfunction may Classified in to 4 categories
Sexual Desire Disorder or Hypoactive sexual desire disorder
- Decreased libido is characterized by a lack or absence for some time of sexual desire or libido for sexual activity or of sexual fantasies.
Causes:
- Decrease in the production of testosterone in men
- Ageing
- Fatigue
- Medications (such as the SSRIs) or psychiatric conditions, such as depression and anxiety.
Sexual Arousal Disorder
Sexual arousal disorders were previously known as impotence in men, though these have now been replaced with less judgmental terms.
Impotence is now known as erectile dysfunction.
For people of all genders, these conditions can manifest themselves as an aversion to and avoidance of sexual contact with a partner.
In men, there may be partial or complete failure to attain or maintain an erection, or a lack of sexual excitement and pleasure in sexual activity.
There may be physiological origins to these disorders, such as decreased blood flow or lack of vaginal lubrication. Chronic disease can also contribute, as well as the nature of the relationship between the partners.
Additionally, the condition post-orgasm illness syndrome (POIS) may cause symptoms when aroused, including adrenergic-type presentation; rapid breathing, paresthesia, palpitations, headaches, aphasia, nausea, itchy eyes, fever, muscle pain and weakness and fatigue.
Duration
From the onset of arousal, symptoms can persist for up to a week in patients.
The etiology of this condition is un known, however it is believed to be a pathology of either the immune system or autonomic nervous systems.
It is defined as a rare disease by the NIH but the prevalence is unknown. It is not thought to be psychiatric in nature, but it may present as anxiety relating to coital activities and thus may be incorrectly diagnosed as such. There is no known cure or treatment.[1][3]
Erectile dysfunction
Erectile dysfunction or impotence is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis.
Causes:
- Damage to the Nervi erigentes which prevents or delays erection, or
- Diabetes
- Cardiovascular disease, which simply decreases blood flow to the tissue in the penis, many of which are medically treatable.
- Psychological or physical. Psychological erectile dysfunction can often be helped by almost anything that the patient believes in; there is a very strong placebo effect.
- Erectile dysfunction from vascular disease is seen mainly amongst older individuals who have atherosclerosis.
- Vascular disease is common in individuals who have diabetes, peripheral vascular disease, hypertension and those who smoke. Anytime blood flow to the penis is impaired, erectile dysfunction is the end result.
other causes
- Drugs Individuals who take drugs that lower blood pressure or antipsychotics, antidepressants, sedatives, narcotics, antacids or alcohol can have problems with sexual function and loss of libido.
- Hormone deficiency is a relatively rare cause of erectile dysfunction.
- In individuals with testicular failure, as in Klinefelter syndrome, or those who have had radiation therapy, chemotherapy or childhood exposure to mumps virus, the testes may fail and not produce testosterone. Other hormonal causes of erectile failure include brain tumors, hyperthyroidism, hypothyroidism or disorders of the adrenal gland.
Orgasm Disorder
Anorgasmia is classified as persistent delays or absence of orgasm following a normal sexual excitement phase in at least 75% of sexual encounters. The disorder can have physical, psychological, or pharmacological origins. SSRI antidepressants are a common pharmaceutical culprit, as they can delay orgasm or eliminate it entirely. A common physiological culprit of anorgasmia is menopause; one in three women report problems obtaining an orgasm during sexual stimulation following menopause.
Premature ejaculation is when ejaculation occurs before the partner achieves orgasm, or a mutually satisfactory length of time has passed during intercourse. There is no correct length of time for intercourse to last, but generally, premature ejaculation is thought to occur when ejaculation occurs in under two minutes from the time of the insertion of the penis. For a diagnosis, the patient must have a chronic history of premature ejaculation, poor ejaculatory control, and the problem must cause feelings of dissatisfaction as well as distress the patient, the partner or both.
- Historically attributed to psychological causes, new theories suggest that premature ejaculation may have an underlying neurobiological cause which may lead to rapid ejaculation.
- Post-orgasmic Disorder
Post-orgasmic disorders cause symptoms shortly after orgasm or ejaculation. Post-coital tristesse (PCT) is a feeling of melancholy and anxiety after sexual intercourse that lasts for up to two hours. Sexual headaches occur in the skull and neck during sexual activity, including masturbation, arousal or orgasm.
Other factors
- In men, post orgasmic illness syndrome (POIS) causes severe muscle pain throughout the body and other symptoms immediately following ejaculation. The symptoms last for up to a week.
- POIS may involve adrenergic symptoms: rapid breathing, paresthesia, palpitations, headaches, aphasia, nausea, itchy eyes, fever, muscle pain and weakness and fatigue.
- The etiology of this condition is unknown; but it may present as anxiety relating to coital activities and thus may be incorrectly diagnosed as such. There is no known cure or treatment.
- Dhat syndrome is another condition which occurs in men. It is a culture-bound syndrome which causes anxious and dysphoric mood after sex, but is distinct from the low-mood and concentration problems (acute aphasia) seen in post orgasm illness syndrome.[1][3]
Sexual pain Disorder
- In men, structural abnormalities of the penis like Peyronie’s disease can make sexual intercourse difficult and/or painful. The disease is characterized by thick fibrous bands in the penis that lead to excessive curvature during erection.
- It has an incidence estimated at 0.4–3% or more, is most common in men 40–70, and is of uncertain cause.
- Risk factors include genetics, minor trauma (including that occurring during cystoscopy or transurethral resection of the prostate), chronic systemic vascular diseases, smoking, and alcohol consumption.
- Priapism is a painful erection that occurs for several hours and occurs in the absence of sexual stimulation. This condition develops when blood gets trapped in the penis and is unable to drain.
- If the condition is not promptly treated, it can lead to severe scarring and permanent loss of erectile function. The disorder is most common in young men and children. Individuals with sickle-cell disease and those who use certain medications can often develop this disorder.
Causes:
- Anxiety Disorder
- Panic disorder
- Aging
- Prostatic Trouble
- Injury to spinal cord
