Vaginismus is a condition in which involuntary muscle spasm interferes with vaginal intercourse or other penetration of the vagina. This often results in pain with attempts at sex.

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.

The underlying cause is generally a fear that penetration will hurt.

Treatment may include behavior therapy such as graduated exposure therapy and gradual vaginal dilation. Botulinum toxin (botox), a muscle spasm treatment, is being studied. Estimates of how common the condition is are varied. One textbook estimates that 0.5% of women are affected, but rates in clinical settings indicate that 5–17% of women experience vaginismus. Outcomes are generally good with treatment.

Signs and symptoms

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

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

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.

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

chronic pain conditions like vulvodynia and harm-avoidance behavior
negative emotional reaction toward sexual stimulation, e.g. disgust both at a deliberate level and a more implicit level
strict conservative moral education, which also can elicit negative emotions

The cause of primary vaginismus is often unknown.

Lamont has classified vaginismus 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.

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".

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.

Mechanism

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

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." 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".

Treatment

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

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.

Often, when faced with a person experiencing painful intercourse, a gynecologist will recommend reverse Kegel exercises and provide lubricants. 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.

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. 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. 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. Research suggests pelvic floor physical or occupational therapy is one of the safest and most effective treatments for vaginismus.

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, a medicine commonly used to treat depression and anxiety.

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. Similar in its mechanism of treatment, lidocaine has also been tried as an experimental option.

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. Evidence for these medications is limited.

Epidemiology

There are no epidemiological studies of the prevalence of vaginismus. Estimates of how common the condition is varies.

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

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." At that time, the condition was understood to be biological in origin and medically treatable. During the 1930s–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.

In popular culture

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

The Netflix show Lady Dynamite season 1 episode 8 titled A Vaginismus Miracle comedically deals with Vaginismus issues.

The animated Netflix show, Big Mouth, season 8 episode 9 features a section explaining "What is vaginismus?"

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