Vaginismus is a condition in which involuntary muscle spasm interferes with vaginal intercourse or other penetration of the vagina. [2] This often results in pain with attempts at sex. [2] Often it begins when vaginal intercourse is first attempted. [3] Vaginismus may be considered an older term for pelvic floor dysfunction. [7]

Contents

The formal diagnostic criteria specifically require interference during vaginal intercourse and a desire for intercourse, but the term vaginismus is sometimes used more broadly to refer to any muscle spasm occurring during the insertion of objects into the vagina, sexually motivated or otherwise, including speculums and tampons. [6] [8]

The underlying cause is generally a fear that penetration will hurt. [3] Risk factors include a history of sexual assault, endometriosis, vaginitis, or a prior episiotomy. [2] Diagnosis is based on the symptoms and examination. [2] It requires there to be no anatomical or physical problems (e.g., pelvic floor dysfunction, vulvodynia, vestibulodynia, etc) and a desire for penetration. [3] [9]

Treatment may include behavior therapy such as graduated exposure therapy and gradual vaginal dilation. [2] [3] Surgery is not generally indicated. [6] Botulinum toxin (botox), a muscle spasm treatment, is being studied. [2] There are no epidemiological studies of the prevalence of vaginismus. [10] Estimates of how common the condition is are varied. [11] One textbook estimates that 0.5% of women are affected, [2] but rates in clinical settings indicate that 5%–17% of women experience vaginismus. [10] Outcomes are generally good with treatment. [6]

Signs and symptoms

Physical symptoms may include burning, and sharp pain or pressure in and around the vagina upon penetration. [12] Psychological symptoms include increased anxiety. [12] Pain during vaginal penetration varies. [13]

Despite being fairly common, there is low social awareness of vaginismus and women have difficulty finding support, even through the healthcare system. [14] A 2023 integrative review found that studies on vaginismus show it often takes years to receive a diagnosis. [14]

Causes

Primary vaginismus

Vaginismus occurs when penetrative sex or other vaginal penetration cannot be experienced without pain. It is commonly discovered among teenage girls and women in their early twenties, as this is when many girls and young women first attempt to use tampons, have penetrative sex, or undergo a Pap smear. Awareness of vaginismus may not happen until vaginal penetration is attempted. Reasons for the condition may be unknown. [15]

A few of the main factors that may contribute to primary vaginismus include:

The cause of primary vaginismus is often unknown. [19]

Lamont has classified vaginismus [20] by severity. Lamont describes four degrees of vaginismus: In first-degree vaginismus, the person's pelvic floor has a spasm that can be relieved by reassurance. In second-degree, the spasm is present but maintained throughout the pelvis even with reassurance. In third-degree, the person elevates the buttocks to avoid being examined. In fourth-degree (also known as grade 4) vaginismus, the severest form, the person elevates the buttocks, retreats, and tightly closes the thighs to avoid examination. Pacik expanded Lamont's classification to include a fifth degree, in which the person experiences a visceral reaction such as sweating, hyperventilation, palpitations, trembling, shaking, nausea, vomiting, losing consciousness, wanting to jump off the table, or attacking the doctor. [21]

Although the pubococcygeus muscle is commonly thought to be the primary muscle involved in vaginismus, Pacik identified two more spastic muscles in people who were treated under sedation. These include the entry muscle (bulbocavernosum) and the mid-vaginal muscle (puborectalis). Spasm of the entry muscle accounts for the common complaint that people often report when trying to have intercourse: "It's like hitting a brick wall". [15]

Secondary vaginismus

Secondary vaginismus occurs when a person who has previously been able to achieve penetration develops vaginismus. This may be due to physical causes, such as a yeast infection or trauma during childbirth, psychological causes, or a combination of causes. The treatment for secondary vaginismus is the same as for primary vaginismus, although, in these cases, previous experience with successful penetration can assist in resolution of the condition. Peri-menopausal and menopausal vaginismus, often due to a drying of the vulvar and vaginal tissues as a result of reduced estrogen, may occur as a result of "micro-tears" first causing sexual pain then leading to vaginismus. [22]

Mechanism

Specific muscle involvement is unclear, but the condition may involve the levator ani, bulbocavernosus, circumvaginal, or perivaginal muscles. [11]

Diagnosis

The diagnosis of vaginismus, as well as other diagnoses of female sexual dysfunction, can be made when "symptoms are sufficient to result in personal distress." [23] The DSM-IV-TR defines vaginismus as "recurrent or persistent involuntary spasm of the musculature of the outer third of the vagina that interferes with sexual intercourse, causing marked distress or interpersonal difficulty". [23]

Treatment

A 2012 Cochrane review found little high-quality evidence regarding the treatment of vaginismus. [24] Specifically, it is unclear whether systematic desensitisation is better than other measures, including nothing. [24]

Psychological

According to a 2011 study, those with vaginismus are twice as likely to have a history of childhood sexual interference and held less positive attitudes about their sexuality, whereas no correlation was noted for lack of sexual knowledge or (nonsexual) physical abuse. [25]

Dilators for treating vaginismus

Often, when faced with a person experiencing painful intercourse, a gynecologist will recommend reverse Kegel exercises and provide lubricants. [8] [26] [27] Although vaginismus has not been shown to affect a person's ability to produce lubrication, additional lubricant can be helpful in achieving penetration. This is because women may not produce natural lubrication if anxious or in pain. Achieving sufficient arousal during foreplay is crucial for the release of lubrication, which can ease sexual penetration and pain-free intercourse.

Strengthening exercises such as Kegel exercises were previously considered a helpful intervention for pelvic pain, but new research suggests that these exercises, which strengthen the pelvic floor, may not be helpful or may make conditions caused by overactive muscles such as vaginismus worse. Exercises that stretch or relax the pelvic floor may be a better treatment option for vaginismus. [28] [29] [30]

To help develop a treatment plan that best fits their patient's needs, a gynecologist or general practitioner may refer a person experiencing painful intercourse to a physical therapist or occupational therapist. These therapists specialize in the treatment of disorders of the pelvic floor muscles, such as vaginismus, pelvic floor dysfunction, dyspareunia, vulvodynia, constipation, and fecal or urinary incontinence. [29] [30] After performing a manual exam internally and externally to assess muscle function and isolate possible trigger points for pain or muscle tightness, therapists develop a treatment plan consisting of muscle exercises, muscle stretches, dilator training, electrostimulation, and/or biofeedback. [29] Treatment of vaginismus often involves Hegar dilators (sometimes called vaginal trainers), progressively increasing the size of the dilator inserted into the vagina. The technique is used to practice conscious diaphragmatic breathing (breathing in deeply allowing one's belly to expand) and allowing the pelvic floor muscles to lengthen during inhale; then exhale, bringing belly in and repeat. [31] [32] Research suggests pelvic floor physical or occupational therapy is one of the safest and most effective treatments for vaginismus. [30]

Many people find vaginal trainers like dilators helpful, but some often need more information on how to use them than is provided, or also seek out lubricant, topical anaesthetic or escitalopram, [14] a medicine commonly used to treat depression and anxiety. [33]

Neuromodulators

Botulinum toxin A (Botox) has been considered as a treatment option, with the idea of temporarily reducing the hypertonicity of the pelvic floor muscles. No random controlled trials have been done with this treatment, but experimental studies with small samples have found it effective, with sustained positive results through 10 months. [11] [34] Similar in its mechanism of treatment, lidocaine has also been tried as an experimental option. [11] [35]

Anxiolytics and antidepressants are other pharmacotherapies that have been offered to people in conjunction with other psychotherapy modalities and to people with high levels of anxiety from their condition. [11] Evidence for these medications is limited. [11]

Epidemiology

There are no epidemiological studies of the prevalence of vaginismus. [10] Estimates of how common the condition is varies. [11] A 2016 textbook estimated about 0.5% of women are affected, [2] while rates in Morocco and Sweden were estimated at 6%. [36]

Among those who attend clinics for sexual dysfunction, rates may be as high as 12% to 47%. [2] [37]

History

The term vaginismus was developed by James Marion Sims in 1866 to describe the “hymeneal hyperaethesia with a spasmodic contraction of the sphincter vaginae” that, under examination, “will produce such agony as to cause the patient to shriek out, complaining at the same time that the pain is that of thrusting a sharp knife into the sensitive part.” [38] At that time, the condition was understood to be biological in origin and medically treatable. During the 1930-1960s, under the influence of Freudian psychology, gynecologists increasingly understood vaginismus as psychological in origin. As psychology turned away from Freudian ideas and toward behaviorism, the condition was re-cast as a learned fear or anxiety response. [39]

The Netflix miniseries Unorthodox depicted a young woman suffering from extreme pain during intercourse, which she was told was due to vaginismus.

The comedy feature film Lady Parts's main character struggles with painful sex and later is diagnosed with vaginismus. [40] [41]

Vulvodynia is a chronic pain condition that affects the vulvar area and occurs without an identifiable cause. Symptoms typically include a feeling of burning or irritation. It has been established by the ISSVD that for the diagnosis to be made symptoms must last at least three months.

<span class="mw-page-title-main">Urinary incontinence</span> Uncontrolled leakage of urine

Urinary incontinence (UI), also known as involuntary urination, is any uncontrolled leakage of urine. It is a common and distressing problem, which may have a large impact on quality of life. Urinary incontinence is common in older women and has been identified as an important issue in geriatric health care. The term enuresis is often used to refer to urinary incontinence primarily in children, such as nocturnal enuresis. UI is an example of a stigmatized medical condition, which creates barriers to successful management and makes the problem worse. People may be too embarrassed to seek medical help, and attempt to self-manage the symptom in secrecy from others.

Dyspareunia is painful sexual intercourse due to somatic or psychological causes. The term dyspareunia covers both female dyspareunia and male dyspareunia, but many discussions that use the term without further specification concern the female type, which is more common than the male type. In females, the pain can primarily be on the external surface of the genitalia, or deeper in the pelvis upon deep pressure against the cervix. Medically, dyspareunia is a pelvic floor dysfunction and is frequently underdiagnosed. It can affect a small portion of the vulva or vagina or be felt all over the surface. Understanding the duration, location, and nature of the pain is important in identifying the causes of the pain.

Persistent genital arousal disorder (PGAD), originally called persistent sexual arousal syndrome (PSAS), is spontaneous, persistent, unwanted and uncontrollable genital arousal in the absence of sexual stimulation or sexual desire, and is typically not relieved by orgasm. Instead, multiple orgasms over hours or days may be required for relief.

Sexual dysfunction is difficulty experienced by an individual or partners during any stage of normal sexual activity, including physical pleasure, desire, preference, arousal, or orgasm. The World Health Organization defines sexual dysfunction as a "person's inability to participate in a sexual relationship as they would wish". This definition is broad and is subject to many interpretations. A diagnosis of sexual dysfunction under the DSM-5 requires a person to feel extreme distress and interpersonal strain for a minimum of six months. Sexual dysfunction can have a profound impact on an individual's perceived quality of sexual life. The term sexual disorder may not only refer to physical sexual dysfunction, but to paraphilias as well; this is sometimes termed disorder of sexual preference.

<span class="mw-page-title-main">Pelvic floor dysfunction</span> Medical condition

Pelvic floor dysfunction is a term used for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. The condition affects up to 50 percent of women who have given birth. Although this condition predominantly affects women, up to 16 percent of men are affected as well. Symptoms can include pelvic pain, pressure, pain during sex, urinary incontinence (UI), overactive bladder, bowel incontinence, incomplete emptying of feces, constipation, myofascial pelvic pain and pelvic organ prolapse. When pelvic organ prolapse occurs, there may be visible organ protrusion or a lump felt in the vagina or anus. Research carried out in the UK has shown that symptoms can restrict everyday life for women. However, many people found it difficult to talk about it and to seek care, as they experienced embarrassment and stigma.

Sexual medicine or psychosexual medicine as defined by Masters and Johnsons in their classic Textbook of Sexual Medicine, is "that branch of medicine that focuses on the evaluation and treatment of sexual disorders, which have a high prevalence rate." Examples of disorders treated with sexual medicine are erectile dysfunction, hypogonadism, and prostate cancer. Sexual medicine often uses a multidisciplinary approach involving physicians, mental health professionals, social workers, and sex therapists. Sexual medicine physicians often approach treatment with medicine and surgery, while sex therapists often focus on behavioral treatments.

<span class="mw-page-title-main">Uterine prolapse</span> Medical condition

Uterine prolapse is a form of pelvic organ prolapse in which the uterus and a portion of the upper vagina protrude into the vaginal canal and, in severe cases, through the opening of the vagina. It is most often caused by injury or damage to structures that hold the uterus in place within the pelvic cavity. Symptoms may include vaginal fullness, pain with sexual intercourse, difficulty urinating, and urinary incontinence. Risk factors include older age, pregnancy, vaginal childbirth, obesity, chronic constipation, and chronic cough. Prevalence, based on physical exam alone, is estimated to be approximately 14%.

Vulvar vestibulitis syndrome (VVS), vestibulodynia, or simply vulvar vestibulitis, is vulvodynia localized to the vulvar vestibule. It tends to be associated with a highly localized "burning" or "cutting" type of pain. Until recently, "vulvar vestibulitis" was the term used for localized vulvar pain: the suffix "-itis" would normally imply inflammation, but in fact there is little evidence to support an inflammatory process in the condition. "Vestibulodynia" is the term now recognized by the International Society for the Study of Vulvovaginal Disease.

A vaginal dilator is an instrument used to gently stretch the vagina. They are used when the vagina has become narrowed, such as after brachytherapy for gynecologic cancers, and as therapy for vaginismus and other forms of dyspareunia.

Vaginal contractions are contractions of the pelvic muscles surrounding the vagina, especially the pubococcygeus muscle. Vaginal contractions are generally an involuntary muscular response to orgasm. Women can control the muscles of the vagina to perform vaginal contractions at will. Vaginal contractions can enhance the sexual experience and pleasure for both parties during sexual intercourse.

A vaginal disease is a pathological condition that affects part or all of the vagina.

Female genital disease is a disorder of the structure or function of the female reproductive system that has a known cause and a distinctive group of symptoms, signs, or anatomical changes. The female reproductive system consists of the ovaries, fallopian tubes, uterus, vagina, and vulva. Female genital diseases can be classified by affected location or by type of disease, such as malformation, inflammation, or infection.

Sex after pregnancy is often delayed for several weeks or months, and may be difficult and painful for women. Painful intercourse is the most common sexual activity-related complication after childbirth. Since there are no guidelines on resuming sexual intercourse after childbirth, the postpartum patients are generally advised to resume sex when they feel comfortable to do so. Injury to the perineum or surgical cuts (episiotomy) to the vagina during childbirth can cause sexual dysfunction. Sexual activity in the postpartum period other than sexual intercourse is possible sooner, but some women experience a prolonged loss of sexual desire after giving birth, which may be associated with postnatal depression. Common issues that may last more than a year after birth are greater desire by the man than the woman, and a worsening of the woman's body image.

A vestibulectomy is a gynecological surgical procedure that can be used to treat vulvar pain, specifically in cases of provoked vestibulodynia. Vestibulodynia is a chronic pain syndrome that is a subtype of localized vulvodynia where chronic pain and irritation is present in the vulval vestibule, which is near the entrance of the vagina. Vestibulectomy may be partial or complete.

Vaginal stenosis is an abnormal condition in which the vagina becomes narrower and shorter due to the formation of fibrous tissue. Vaginal stenosis can contribute to sexual dysfunction, dyspareunia and make pelvic exams difficult and painful. The lining of the vagina may also be thinner and drier and contain scar tissue. This condition can result in pain during sexual intercourse or a pelvic exam. Vaginal stenosis is often caused by radiation therapy to the pelvis, an episiotomy, or other forms of surgical procedures. Chemotherapy can also increase the likelihood of developing vaginal stenosis. Vaginal stenosis can also result from genital reconstructive surgery in people with congenital adrenal hyperplasia.

Pelvic floor physical therapy (PFPT) is a specialty area within physical therapy focusing on the rehabilitation of muscles in the pelvic floor after injury or dysfunction. It can be used to address issues such as muscle weakness or tightness post childbirth, dyspareunia, vaginismus, vulvodynia, constipation, fecal or urinary incontinence, pelvic organ prolapse, and sexual dysfunction. Licensed physical therapists with specialized pelvic floor physical therapy training address dysfunction in individuals across the gender and sex spectra, though PFPT is often associated with women's health for its heavy focus on addressing issues of pelvic trauma after childbirth.

<span class="mw-page-title-main">Vaginal introital laxity</span> Medical condition

Vaginal introital laxity is a symptom of pelvic floor dysfunction characterised by a sensation of looseness at vaginal external opening, also known as the vaginal introitus. Possible causes include pelvic organ prolapse (POP), post-pregnancy and vaginal delivery and menopause. Consequences may include experiencing sexual dysfunction, ranging from dyspareunia, increased vaginal “wind” to overactive bladder (OAB). These consequences may lead to adverse significant impacts on women’s sexual health, body image and quality of life. Vaginal laxity is often underreported, with approximately 80% of women not seeking treatment or discussing their concerns.
