Sexual Dysfunction



A woman's sexuality is a complex interplay of physical and emotional responses that affects the way she thinks and feels about herself. When a woman has a sexual problem, it can impact many aspects of her life, including her personal relationships and her own self-esteem. Many women are hesitant to talk about their sexuality with their health care professionals and many health professionals are reluctant to begin a discussion about sexuality with their patients. Instead, women may needlessly suffer in silence when their problems could be treated.

Sexual activity includes a wide variety of intimate activities, such as fondling, self-stimulation, oral sex, vaginal penetration and intercourse. Every woman differs in her sexual interest, response and expression. A woman's feelings about sexuality can change according to the circumstances and stages of her life. Women also can experience a variety of sexual problems, such as lack of desire, difficulty becoming aroused, difficulty having an orgasm or pain during sex. When a physical or emotional problem associated with sex persists, it's time to contact a health care professional.

Excitement/Arousal: The feeling that you want to have sex followed by physical changes that occur in your body as you become sexually excited. These include moistening of the vagina, relaxation of the muscles of the vagina; swelling of the labia, (skin folds that are part of the vulva), and the clitoris (a small, sensitive organ above the vagina, where the inner labia, which surrounds the vagina, meet that acts as a source of sexual excitement). The nipples also become erect.

Plateau: The above changes in the genitals continue, there is an increase in blood flow to the labia, the vagina grows longer and glands in the labia produce secretions. There is an overall increase in muscle tension.

Orgasm: Known as the peak of the sexual response, the muscles of the vagina and uterus contract leading to a strong, pleasurable feeling.

Resolution: You return to your normal state.

In a new sexual relationship, most women's sexual response can be described with this model. However, more contemporary research suggests that women's sexual response is both more complex and varied than this model suggests, particularly when involved in a long-term relationship. In 2001, the leader in this field, Rosemary Basson, PhD, introduced a new cycle for the female sexual response that focuses on women's need for intimacy.

These differences are important to understanding your sexual health as well as for accurately diagnosing and treating sexual dysfunction. The differences, in part, include recognizing that women's sexual responses are connected more to relationship and intimacy than to physical needs, and that the orgasm stage can be highly variable for women without actually being "dysfunctional."

Sexual dysfunctions are disturbances in one or more of the sexual response cycle's phases, or pain associated with arousal or intercourse. A study published in the Journal of the American Medical Association involving a national sample of 1,749 women estimated that sexual dysfunctions occur in 43 percent of women in the United States. According to this 1999 study, you may be at greater risk for sexual problems if you are:

single, divorced, widowed or separated

not a high school graduate

experiencing emotional or stress-related problems

experiencing a decline in your economic position

feeling unhappy, or physically and emotionally unsatisfied

a victim of sexual abuse or forced sexual contact

There are several types of sexual dysfunctions. They can be lifelong problems that have always been present, acquired problems that develop after a period of normal sexual function, or situational problems that develop only under certain circumstances or with certain partners. Causes of sexual dysfunctions can be psychological, physical or related to interpersonal relationships or sociocultural influences.

Psychological causes can include:

stress or anxiety from work or family responsibilities

concern about sexual performance

conflicts in the relationship with your partner

depression/anxiety

unresolved sexual orientation issues

previous traumatic sexual or physical experience

body image and self-esteem problems

Physical causes can include:

diabetes

heart disease

liver disease

kidney disease

pelvic surgery

pelvic injury or trauma

neurological disorders

medication side effects

hormonal changes, including those related to pregnancy and menopause

thyroid disease

alcohol or drug abuse

fatigue

Interpersonal relationship causes may include:

partner performance and technique
lack of a partner
relationship quality and conflict
lack of privacy
Sociocultural influence causes may include:

inadequate education
conflict with religious, personal, or family values
societal taboos
Lack of sexual desire is the most common sexual problem in women. The Association of Reproductive Health Professionals reports in the National Health and Social Life Survey that 33 percent of women lacked interest in sex for at least a few months in the previous year. Meanwhile, the Merck Manual of Diagnosis and Therapy estimates about 15 percent of postmenopausal women have declines in sexual desire.

The American College of Obstetricians and Gynecologists (ACOG) reports that a woman's sexual response tends to peak in her mid-30s to early 40s. That's not to say, however, that a woman can't have a full physical and emotional response to sex throughout her life. In fact, the 1999 JAMA study found that except for lubricating disorders, the prevalence of many sexual problems among women tends to decrease with age. Most women will have a passing sexual problem at some point in their lives, and that is normal.

If your relationship or sexual problem is new, try having an open, honest talk with your partner to relieve concerns and clear up disagreements or conflicts. Women who learn to tell their partners about their sexual needs and concerns have a better chance at a more satisfying sex life. If the sexual problem persists, do discuss your concerns with your health care professional. Most sexual problems can be treated.

Sexual Problems
Often, sexual desire is affected by a woman's relationship with her sexual partner. The more a woman enjoys the relationship, the greater her desire for sex. The stresses of daily living can affect desire, however, and occasionally feeling uninterested in sex is no cause for concern. But when sexual fantasies or thoughts and desire for sexual activity are persistently reduced or absent causing distress or relationship difficulties, the problem is known as hypoactive sexual desire disorder, or inhibited sexual desire disorder. The Merck Manual of Diagnosis and Therapy estimates hypoactive sexual desire disorder occurs in about 20 percent of women.

Sexual aversion disorder is diagnosed when you avoid all or almost all genital sexual contact with a sexual partner to the point that it causes personal distress and relationship difficulties. This condition may affect women who have experienced some type of sexual abuse, or who grew up in a rigid atmosphere in which sex was taboo. A study in the journal Archives of Sexual Behavior found that among patients with panic disorder, 75 percent had sexual problems, and that sexual aversion disorder was the most common complaint, affecting 50 percent of women with the disorder.

Sexual arousal disorder is the persistent or recurrent inability to reach or sustain the lubrication and swelling reaction in the arousal phase of the sexual response to the point that it causes personal distress. It is the second most common sexual problem among women, affecting 15 to 20 percent of women, and most frequently occurs in postmenopausal women. Low estrogen levels after menopause can make vaginal tissue dry and thin and reduce blood flow to genitals. As a result, the arousal phase of the sexual response may take longer and sensitivity of the vaginal area may decline. However, this can happen at any age.

Female orgasmic disorder refers to the persistent absence or recurrent delay in orgasm after sufficient stimulation and arousal, causing personal distress. About 10 percent of women never attain an orgasm, regardless of stimulation or situation. About half of women regularly have an orgasm during intercourse, according to the Merck Manual.

Most women are biologically able to experience orgasm. Never having an orgasm, or not having one in certain situations, are problems that can often be resolved by learning how the female body responds, how to ensure adequate stimulation and/or how to overcome inhibitions or anxieties.

Some medications, including but not limited to those used to treat high blood pressure, depression and psychosis, can reduce your sexual desire and sexual arousal and interfere with orgasm. If you are taking such drugs and experiencing sexual side effects, talk with your health care professional about changing your dosage or prescription.

Another type of sexual arousal disorder has the opposite effect. Some women may always feel sexually aroused, an experience that can be quite uncomfortable and upsetting. Although most health care professionals recognize hyperactive sexual desire as a problem, it is not an official condition according to the DMS-IV. Women who have a hyperactive sexual drive tend to be very demanding sexually because their desire for sex is constant.

Sexual Disorders Involving Pain
Pain during or after intercourse, called dyspareunia, occurs in nearly two out of three women at some time during their lives, according to ACOG. Like other sexual disorders, it can have physical and/or emotional causes. The most common cause of pain during sex is inadequate vaginal lubrication occurring from a lack of arousal, medications or hormonal changes. Painful sex also can be a sign of illness, infection, cysts or tumors requiring medical treatment or surgery, another reason why you should discuss the problem with your health care professional.

Another type of sexual pain disorder is vaginismus, which is the involuntary spasm of the muscles at the opening of the vagina, making anything entering the vagina painful. Vaginismus can have medical causes, including:

scars in the vagina from an injury, childbirth or surgery

irritations from douches, spermicides or latex in condoms

pelvic infections

Vaginismus also can have psychological causes. It can be a response to a fear, such as fear of losing control or fear of pregnancy. It can also stem from pain or trauma such as rape or sexual abuse.

Another type of sexual pain disorder is vulvodynia. It is defined as any pain in the vulva. It could be outside the vulva on the labia, or an itching, burning or sharp pain within.
