Вагинизм: причины, симптомы и методы лечения.

Involuntary muscle spasm that interferes with vaginal penetration

The formal diagnostic criteria specifically requires interference during vaginal intercourse and a desire for intercourse. However, the term vaginismus is sometimes used more broadly to refer to any muscle spasm occurring during the insertion of some or all types of objects into the vagina, sexually motivated or otherwise, including the usage of 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 dilatation. Botulinum toxin (botox), a muscle spasm treatment, is being studied. Estimates of how common the condition is are varied. Psychological symptoms include increased anxiety. Despite it being a fairly common female sexual dysfunction, there is low social awareness of vaginismus and women around the world face difficulties finding support, even through the healthcare system. An integrative review published in 2023 found that studies on vaginismus show it often takes years to finally receive a diagnosis
negative emotional reaction towards sexual stimulation, e. g. disgust both at a deliberate level and also at a more implicit level
strict conservative moral education, which also can elicit negative emotions

The cause of primary vaginismus is often unknown. Vaginismus has been classified by Lamont according to the severity of the condition. Lamont describes four degrees of vaginismus: In first degree vaginismus, the person has spasm of the pelvic floor that can be relieved with 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 vaginismus (also known as grade 4 vaginismus), the most severe form of vaginismus, the person elevates the buttocks, retreats and tightly closes the thighs to avoid examination. Pacik expanded the Lamont 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 additionally involved 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 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, while in some cases it may be due to psychological causes, or to 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 a more rapid 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.

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

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". Specifically it is unclear if systematic desensitisation is better than other measures including nothing.

Often, when faced with a person experiencing painful intercourse, a gynecologist will recommend reverse Kegel exercises and provide some additional lubricants. Although vaginismus has not been shown to affect a person's ability to produce lubrication, providing additional lubricant can be helpful in achieving successful penetration. This is due to the fact that 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 contribute to the ease of sexual penetration and pain free intercourse. Though strengthening exercises such as Kegel exercises were previously considered to be a helpful intervention for pelvic pain, new research suggests that these exercises, which function to strengthen the pelvic floor, may not be helpful or may make conditions that are caused by over active 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 the needs of their patient, a gynecologist or general practitioner may refer a person experiencing painful intercourse to a Pelvic floor 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. Research suggests pelvic floor physical or occupational therapy is one of the safest and most effective treatments for vaginismus.

Botulinum toxin A (Botox) has been considered as a treatment option, under the idea of temporarily reducing the hypertonicity of the pelvic floor muscles. Although no random controlled trials have been done with this treatment, experimental studies with small samples have shown it to be 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, or if these people's experience high levels of anxiety from their condition. Among those who attend clinics for sexual dysfunction, rates may be as high as 12 to 47%.

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 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.

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, main character struggles with painful sex and later is diagnosed with vaginismus.
