Overview

Information

An impairment during any stage of the sexual response cycle (desire, arousal, orgasm, and resolution) that prevents the individual or couple from experiencing satisfaction as a result of sexual activity.

CAUSES, INCIDENCE, AND RISK FACTORS
Sexual dysfunction can be present throughout life or may develop after an individual has previously experienced normal sexual responses. The impairment may develop gradually over time, or may occur suddenly and present itself either as total or partial dysfunction in one or more stages of the sexual response cycle. The cause of sexual dysfunction may be physical, psychological, or both.

Emotional factors include both interpersonal problems (such as marital/relationship disharmony, or lack of trust and open communication between partners) and psychological problems within the individual (depression, sexual fears or guilt, past sexual trauma, and so on).

Physical factors include drugs (alcohol, nicotine, narcotics, stimulants, antihypertensives, antihistamines, or most psychotherapeutic drugs); complications related to back, prostate, or vascular (blood vessel) surgeries; neurological problems caused by trauma (such as spinal cord injuries) or disease (such as diabetic neuropathy, multiple sclerosis, tumors, and, rarely, tertiary syphilis); failure of various organ systems (such as the circulatory and respiratory systems); endocrine disorders (thyroid, pituitary, or adrenal gland problems); hormonal deficiencies (low testosterone or androgens); and some fetal development abnormalities.

Sexual dysfunction disorders are generally classified into four categories: sexual desire disorders, sexual arousal disorders, orgasm disorders, and sexual pain disorders.

Sexual desire disorders or decreased libido may have a hormonal cause from a decrease in normal androgen or testosterone hormone production. Other causes may be aging, fatigue, pregnancy, medications, or psychiatric conditions such as depression and anxiety.

Sexual arousal disorders are sometimes referred to as frigidity in women and impotence in men. For men and women there may be 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 medical causes to these disorders, such as blood flow problems or lack of lubrication. Chronic disease and the nature of the relationship between the partners are other possible causes.

Orgasm disorders are a persistent delay or absence of orgasm following a normal sexual excitement phase. The disorder can occur in both women and men.

Sexual pain disorders affect women almost exclusively and are known as dyspareunia (painful intercourse) and vaginismus (an involuntary spasm of the musculature of the vagina that interferes with intercourse). Dyspareunia may be caused by insufficient lubrication in the female. Insufficient lubrication may be caused by breastfeeding, irritation from contraceptive creams and foams, aging, or by fear and anxiety. Vaginismus may be caused by a sexual trauma such as rape or incest.

Sexual dysfunctions are more common in the early adult years, with the majority of people seeking care for such conditions during their late twenties into their thirties. The incidence increases again in the geriatric population, typically with gradual onset of symptoms that are associated most commonly with organic causes of sexual dysfunction.

Increased risk is associated with a history of diabetes, degenerative neurological disorders, chronic psychological problems, alcohol use and drug abuse, difficulty maintaining relationships, or chronic disharmony with the current sexual partner.

PREVENTION
Open, informative, and accurate communication regarding sexual issues and body image between parents and their children may prevent children from developing anxiety or guilt about sex and carrying those emotional responses into their adulthood.

Review all medications, both prescription and over-the-counter, for possible side effects that relate to sexual dysfunction. Avoiding drug and alcohol abuse may help prevent sexual dysfunction.

Couples developing and practicing adequate communication may be able to avoid some problems within their relationship that could potentially create some forms of sexual dysfunction.

People who are victims of sexual trauma such as sexual abuse or rape at any age should receive comprehensive treatment, including individual counseling and group therapy. Such care may prove beneficial in allowing them to fully enjoy voluntary sexual experiences with a partner of their choice.

SYMPTOMS

• men or women
  • lack of interest or desire in sex (loss of libido)
  • inability to feel aroused
  • pain with intercourse (much less common in men than women)
  • infertility
• men
  • inability to attain an erection
  • inability to maintain an erection adequately for intercourse
  • delay or absence of ejaculation despite adequate stimulation
  • inability to control timing of ejaculation
• women:
  • inability to relax vaginal muscles enough to allow intercourse
  • inadequate vaginal lubrication preceding and during intercourse
  • inability to attain female orgasm

SIGNS AND TESTS
Specific physical findings and testing procedures depend on the form of sexual dysfunction being investigated. In any case, a complete history and physical examination should be done to identify predisposing illness or conditions; highlight possible fears, anxieties, or guilt specific to sexual behaviors or performance; and elicit any history of prior sexual trauma. A physical examination of both the partners should include all systems and not be limited to the reproductive system.

TREATMENT
Treatment measures depend on the cause of the sexual dysfunction. Organic causes that are reversible or treatable are usually managed medically or surgically. Physical therapy and mechanical aides may prove helpful for some people experiencing sexual dysfunction due to physical illnesses, conditions, or disabilities. For men, the medication sildenafil (Viagra) often helps improve both organic and psychological sexual dysfunction by increasing blood flow to the penis. Men on nitrates for coronary heart disease should not take sildenafil, because it may cause dangerous drug interactions. Mechanical aids and penile implants are sometimes used. Men with androgen deficiency sometimes benefit from testosterone shots. Women with androgen deficiency can take smaller doses of testosterone orally or apply it topically with a cream.

Behavioral treatments involve many different techniques to treat problems associated with orgasm and sexual arousal disorders. Self-stimulation and the Masters and Johnson treatment strategies are only two of many behavioral therapies used.

Simple, open, accurate, and supportive education about sex and sexual behaviors or responses may be all that is required. Some couples may require joint counseling to address interpersonal issues and communication styles. Psychotherapy may be required to address anxieties, fears, inhibitions, or poor body image.

PROGNOSIS AND OUTCOME
The prognosis (probable outcome) depends on the form of sexual dysfunction. In general, the probable outcome is good for physical (organically caused) dysfunctions resulting from treatable or reversible conditions. It should be noted, however, that many organic causes do not respond to medical or surgical treatments. In functional sexual problems resulting from either relationship problems or psychological factors, the prognosis may be good for temporary or mild dysfunction associated with situational stressors or lack of accurate information. However, those cases associated with chronically poor-functioning relationships or deep-seated psychiatric problems typically do not have positive outcomes.

COMPLICATIONS
Some forms of sexual dysfunction may cause infertility.

Persistent sexual dysfunction may cause depression in some individuals. The importance of the disorder to the individual (and couple, when applicable) needs to be determined. Sexual dysfunction that is not addressed adequately may lead to conflicts or potential breakups within couples.
