See patient information handout on dyspareunia, written by the author of this article.

Dyspareunia is genital pain associated with sexual intercourse. Although this condition has historically been defined by psychologic theories, the current treatment approach favors an integrated pain model. Identification of the initiating and promulgating factors is essential to reaching a successful diagnosis. The differential diagnoses include vaginismus, inadequate lubrication, atrophy and vulvodynia (vulvar vestibulitis). Less common etiologies are endometriosis, pelvic congestion, adhesions or infections, and adnexal pathology. Urethral disorders, cystitis and interstitial cystitis may also cause painful intercourse. The location of the pain may be described as entry or deep. Vulvodynia, atrophy, inadequate lubrication and vaginismus are associated with painful entry. Deep pain occurs with the other conditions previously noted. The physical examination may reproduce the pain, such as localized pain with vulvar vestibulitis, when the vagina is touched with a cotton swab. The involuntary spasm of vaginismus may be noted with insertion of an examining finger or speculum. Palpation of the lateral vaginal walls, uterus, adnexa and urethral structures helps identify the cause. An understanding of the present organic etiology must be integrated with an appreciation of the ongoing psychologic factors and negative expectations and attitudes that perpetuate the pain cycle.

Dyspareunia is genital pain experienced just before, during or after sexual intercourse.1 Although this condition has historically been classified as a sexual disorder, an integrated and pain-model approach to the problem is gaining support. The current thinking about pain initiation and promulgation suggests an initial instigating factor that is then perpetuated by confounding factors.26 These factors may be physical or psychologic. Patients with dyspareunia may complain of a well-defined and localized pain, or express a general disinterest in and dissatisfaction with intercourse that stems from the associated discomfort. Although dyspareunia is present in both sexes, it is far more common in women, with the pain initiating in several areas, from vulvar surfaces to deep pelvic structures.

This article reviews the various causes of dyspareunia and describes the historical and physical clues leading to these diagnoses. Treatment options are beyond the scope of this article.


There are few reports of clinical trials relating to dyspareunia, and much of the literature derives from expert opinion. The lack of a single etiology for the pain contributes to the diagnostic difficulty. The incidence of dyspareunia depends on the definition used and the population sampled. In a national probability sample7 assessing the prevalence of sexual dysfunction in the United States, women with dyspareunia comprised a smaller group than women with decreased interest in sex, orgasmic difficulties, lack of pleasure or arousal difficulties. The prevalence of dyspareunia in this sample was 7 percent. In a study of primary care practices,8 the prevalence of dyspareunia was 46 percent among sexually active women, with dyspareunia defined as pain during or after intercourse. In a recent study9 involving 62 women, postpartum dyspareunia was noted in 45 percent.

As many as 60 percent of women experience dyspareunia when the term is broadly defined as episodes of pain with intercourse.10 Women with symptoms severe enough to require medical attention comprise a much smaller group. Many of those with persistent symptoms do not seek medical attention.8,10


Consistent characteristics of patients with dyspareunia are lacking. In one study,7 increasing age and college education were associated with a lower likelihood of dyspareunia. In another study,8 the incidence of dyspareunia was not associated with age, parity, marital status, race, income or educational level.

The most common pain with dyspareunia occurs during coitus, but some women experience pain afterward, while others report pain at both times.8 Pain before coitus may result from irritation of the external genitalia or the vasocongestion that occurs during the excitement phase. Patients with dyspareunia are more likely than the general population to report pain with insertion of a tampon or digit, or during a gynecologic examination.6

Psychologic Issues and Considerations

Psychologic theory historically treats dyspareunia as a symbol of unconscious conflict, stemming from phobic reactions, major anxiety conflicts, hostility or sexual aversions.4 The Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV),11 defines dyspareunia as a sexual pain disorder, a subcategory of sexual dysfunction. Dyspareunia is differentiated from vaginismus or problems resulting from inadequate lubrication. The pain must be persistent or recurrent, and cause marked distress or interpersonal difficulty. In one study,5 only the onset of pain and its location were useful discriminators.

Because of the differences in classification and the multiple etiologies, it has been difficult to accurately and consistently describe comorbid psychologic characteristics. Dyspareunia has been associated with a more negative attitude toward sexuality, with more sexual function impairment and with lower levels of relationship adjustment.6 Women with dyspareunia, not surprisingly, were found to have a lower frequency of intercourse and lower levels of desire and arousal, and to be less orgasmic with oral stimulation and intercourse.7 Complaints of pain with sexual intercourse were also associated with low physical and emotional satisfaction, as well as decreased general happiness. Depression and phobic anxiety were noted more often in patients with dyspareunia compared with control subjects,6 but other studies found no difference from norms with regard to psychopathology, marital adjustment or attitudes towards intercourse.5,12

Marital discord has been suggested as a major cause of dyspareunia, but whether the marital relationship suffered secondarily because of difficulty with sexual intercourse is unclear.12 The results of one study13 revealed that marital adjustment was inversely associated with dyspareunic pain rating and that only anxiety and marital adjustment were significant independent predictors of dyspareunic pain rating. Depression was not found to be a predictor when patients with dyspareunia were evaluated as a whole.13

Compared with patients with pelvic pain,2 patients with dyspareunia did not report a current or previous history of physical or sexual abuse.6,12 The role of previous sexual abuse in dyspareunia has been the subject of much study, but the results lack consistency because of methodologic flaws. There may be subsets of patients, such as those with sexual arousal disorders, with a higher sexual victimization rate.7

Given the lack of consistent study results, it is unlikely that currently available psychologic screening instruments would have a prominent role in the diagnosis of dyspareunia and related pain syndromes. A discussion of external factors, overall relationship satisfaction and current psychologic status may prove fruitful in certain patients, but its value is difficult to predict.


This integrated pain model emphasizes that physical and psychologic factors may be instigating causes and reasons for perpetuation of the symptoms. The optimal approach incorporates social learning and operant conditioning models with pain, psychologic and physical conditions. The Learning theory suggests that erroneous or negative expectations of sexual intercourse are the result of absent or faulty learning.4 The Developmental theory examines the impact of early influences on the formation of negative attitudes.14 The Operant Conditioning model supposes that negative events occur (i.e., a woman has a painful sexual experience), which then cause a conditioned negative response. This result leads to further dissatisfaction and decreased response, and sexual activities then become painful. In the Operant Conditioning theory, the woman does not initially present with a set of negative expectations, feelings or attitudes.4


Obtaining a history is of paramount importance for a diagnosis, but the process may be hampered by the woman's embarrassment when discussing the topic. The manner of questioning requires a nonjudgmental approach, with a mixture of directed and openended questions. The history should include pain descriptors: duration, intensity, location, exacerbating and ameliorating factors, and any associated physical or psychologic components15 (Tables 1 and 2).16 The physician distinguishes between primary and secondary dyspareunia based on whether the woman has ever had a history of successful sexual experiences. Previous treatments and the degree of response to them are important information. Not all physicians are comfortable or adept in dealing with this topic, and we must recognize our limitations and refer appropriately.

Asking patients during routine office visits if they experience discomfort with sexual intercourse or if they find it pleasurable will assist in identifying women who need additional evaluation.

In order to assess appropriate treatment response, it is useful to determine the duration of the problem and if it is present with other sexual partners. It is unwise to assume that the patient is in a monogamous relationship or is heterosexual. The goals of the history are to identify medical or gynecologic causes of pain, to define the sexual problems and to gather psychosocial information (Table 3).16

The pelvic examination may be deferred during the first office visit, depending on the intensity of the patient's discomfort. It is extremely important to allow the patient control over the situation, which means the patient must feel free to stop the examination at any time. Because many women do not have adequate knowledge of their genital structures or function, giving the patient a mirror during the examination involves her in the evaluation process and provides education.15

When tenderness is elicited during the examination, the physician can ascertain if this pain is similar to her dyspareunia. Special attention should be paid to the external genital structures, noting any lesions, leukoplakia or erythema. In patients with vulvar disease, the vulvar area may be exquisitely tender, and the patient may be unable to tolerate insertion of a speculum. The physician should carefully examine the vestibular area and Bartholin's ducts, Skene's ducts, urethra and meatus, using a moistened cotton-tipped applicator. Areas of erythema or tenderness should be noted. Some women have minute papillae of the vestibular skin, a normal variant that does not represent viral or other disease entities.

Following visual inspection, the physician next performs a vaginal evaluation with one finger before performing the bimanual evaluation to minimize confusion arising from abdominal tenderness. Muscular pain can be assessed with insertion of one finger at the introitus as the patient performs a series of contraction and relaxation exercises. Vaginis mus may be apparent during this examination, but one fourth of women who tolerate pelvic examinations or tampon insertion have involuntary spasms during coitus.15 The lateral walls of the vagina should be palpated along the bladder and urethra anteriorly, and the posterior wall and fornices. Any tenderness or nodules, and the position of the uterus should be noted.

The vagina should be evaluated using a narrow and well-lubricated speculum. During assessment of mucosal integrity, the presence or absence of vaginal rugae, fissures or friable tissue should be noted. To assist in determining the degree of vaginal atrophy, the physician may use a scoring system, including such characteristics as skin elasticity, pubic hair, labial fullness and evaluation of the introital and vaginal depth.16 Inspection of the cervix may detect dysplastic lesions or evidence of infection, which dictates further evaluation, including obtaining a Papanicolaou smear, cultures or wet mounts. The fornices should be palpated around the cervix for nodules suggestive of endometriosis, and may also be the etiology for fixed adnexa or may result from pelvic inflammatory disease.

Description by Disease or Condition


The International Society for the Study of Vulvar Diseases classification of vulvodynia includes any type of vulvar pain.17 The etiology is often elusive, although infection is a possibility. Alternatively, vulvodynia may be the result of a reaction to chemicals that sets up a cyclic pattern of irritation and tissue response, much like eczema. In the past, the lack of an underlying etiology has led to considerable frustration on the part of patients and physicians.

The diagnosis remains one of exclusion because underlying conditions such as diabetes or regional enteritis may produce similar symptoms. Behçet's syndrome is an idiopathic disease; patients may present with oral and genital ulcers that can cause vulvar pain. Lichen sclerosis must be excluded in addition to common infectious etiologies including Candida, bacterial vaginosis and trichomonas.

The patient typically has a history of multiple treatments with little or no relief. The earliest manifestations of dyspareunia occur with sexual contact, but the symptoms then increase to the point that the pain interferes with nonsexual activities. Erythema over the posterior portion of the vulva, especially around the Bartholin gland openings, may be the only visible evidence.18

The condition is now better recognized, and treatment options are available. The various classifications and treatments have been described elsewhere.17


Vulvar vestibulitis, a subcategory of vulvodynia, is a chronic and painful inflammation of the vestibular structures. Inciting factors are unknown, but infections have been postulated. Candida and human papillomavirus (HPV) are found in some but not all cases.19,20 Histopathology reveals inflammatory infiltrate. The characteristics of this condition are slightly more distinct than those of vulvodynia, with a localized area of pain to palpation or with vaginal penetration. Point tenderness elicited with a cotton swab is quite common. Flat, non-ulcerated erythema of the vestibule may be focal or diffuse.17


Although the DSM-IV11 distinguishes between dyspareunia and vaginismus, when a patient presents with complaints of painful sex, she may be describing either condition or a combination of both. Vaginismus is involuntary spasms of the introital (bulbocavernosus) muscles.

Previous theories centered on psychologic etiologies, but recent discussions point to a conditioned response of the vaginal musculature.4 Negative attitudes toward sex and sexual ignorance have also been associated with vaginismus. Insertions of a finger, penis or tampon are common triggers of the spasm.


Inadequate lubrication in younger women is associated with an inhibited arousal phase, but estrogen deficiency predominates as a reason in older women. It is important to ascertain if the patient senses arousal and lubrication. Patients who lack adequate arousal may be counseled in foreplay techniques. Instability of the relationship and interpersonal conflict may contribute to lack of arousal.21 Unfortunately, psychologic factors may now be part of a vicious circle. Although the lack of arousal and difficulty in lubrication initially stemmed from irritation or unsatisfactory sexual techniques, they then become a repetitive and expected component of coitus.22

Presacral neurectomy surgery for the treatment of chronic pelvic pain can interfere with the normal lubrication response. The couple with penetration difficulty because of inadequate lubrication will most likely have tried various agents, but some of these products are more suitable than others for satisfactory intercourse. A variety of water-based products (i.e., Astroglide, Replens) have been well received.


The etiology for postpartum dyspareunia remains unclear. In one study,9 45 percent of the patients had entry pain, a small percentage had pain at the site of vulvar repair and the remaining 39 percent had nonfocal pain. Only a slight difference in pain existed between women having a first delivery versus those having a second delivery. Over one quarter of the women in this study who underwent cesarean section had pain, while 41 percent of lactating women had dyspareunia. The median time to resolution of the nonfocal dyspareunia was 5.5 months, and tenderness persisted up to one year.

Description by Pain Location

Pain may occur before entry, with entry or once the penis is in the vagina. The timing of the pain can provide clues to the etiology. Table 4 and Table 5 list the common diagnoses and associated conditions. In most studies,5,6 the majority of women report pain with vaginal entry. In another study8 of 248 women, deep pain accounted for more than one half of those presenting with dyspareunia, while pain at entry or pain at both sites were considerably less common. The discrepancies in study results may reflect different subgroups of patients.8

Entry dyspareunia may result from a variety of conditions affecting the labia or vestibule. A history of pain with entry is most commonly associated with vaginismus and inadequate lubrication from incomplete arousal.12 Entry pain is also suggestive of atrophy, vulvodynia and transient causes such as fungal or bacterial vaginitis and vulvar dystrophies. Atrophic changes from inadequate estrogen levels may also cause entry dyspareunia, although the pain typically extends into the vaginal area as well.

Ulcerations and fissures are apparent with careful inspection. Herpes simplex virus (HSV) or HPV infections may cause superficial dyspareunia, although the impact of HPV in this situation is disputed.20,23 Lesions associated with HSV are easily identified or the patient may report a history of previous eruptions with sexual pain limited to times of active infection. On examination, tenderness along the urethra or bladder suggests urethritis, urethrodiverticulum or urethral syndrome.24


Atrophic changes and inadequate lubrication cause problems with dryness or friction with penile movement. The vaginal barrel may not distend and elongate in response to the arousal phase, and this may cause discomfort, particularly in certain positions or with penile impact on the cervix.

The pain associated with deep thrusting is often described as “something being bumped into.” Etiologies include endometriosis, pelvic adhesions and pelvic congestion.2427 Adnexal pathology, endometritis and scarring from pelvic inflammatory disease are less frequent causes of dyspareunia. A minority of women with uterine retroversion and pelvic relaxation have pain.

The urinary system is also a source of dyspareunia. Cystitis or interstitial cystitis cause pain as the bladder fills. Reports of symptoms include suprapubic pressure, frequency, nocturia and urgency without dysuria. Dyspareunia may be part of the initial presentation, which then proceeds to a persistent chronic pain.27 Inflammatory bowel disease and irritable bowel syndrome may cause dyspareunia, but they are more often associated with other diagnoses of chronic pelvic pain.27

Additional Studies

Examination of the labia, vagina and cervix is greatly enhanced with the use of a colposcope. Application of acetic acid highlights any acetowhite lesions but may cause the patient significant discomfort.

Vulvar biopsy is easily performed, especially with the use of a colposcope, to aid in the detection of areas of leukoplakia or acetowhite areas. Application of Monsel's solution, cautery or silver nitrate stick is usually sufficient for any minor bleeding caused by the biopsy. A fine suture may also be used to close the biopsy site, but this is rarely needed. In cases of true vestibulitis, results of the cultures and the biopsy are negative or reveal only reactive or inflammatory changes.18
