Vaginismus: Common and Can Be Assessed — Causes and an Individual Approach

Finding attempts at intercourse painful or impossible is an experience that many women do not raise on their own for a long time. The American College of Obstetricians and Gynecologists (ACOG) reports that women tend not to discuss problems with sexual function with healthcare professionals unless they are asked ¹. This article explains, with sources, what vaginismus is, what factors it arises from, how an obstetrician and gynaecologist carries out the assessment and what results scientific studies have reported.

Vaginismus is an involuntary contraction of the pelvic floor muscles that makes intercourse difficult or impossible ^1,2. The contraction can also occur when a tampon, a finger or an examination instrument (speculum) is inserted ³. If a woman has never been able to have intercourse, this is called “lifelong (primary) vaginismus” ³; the form that develops later is called “acquired (secondary)” and is considered separately in studies ⁴. The contraction is not voluntary; even when the person wants to, her body does not allow it ². The diagnostic criteria cited by ACOG also include fear or anxiety about pain ¹; in studies, fear of intercourse has been measured and seen to decrease with treatment ³.

How common is it?

Its true frequency in the population is hard to measure, because the subject is often not raised even with a doctor ¹. A study published from Türkiye describes vaginismus as “a common sexual dysfunction” in the country ⁵. The data from the same study are noteworthy: in a sample of 54 women who attended a psychiatry department with sexual problems, 75.9% of the primary diagnoses were vaginismus ⁵. This figure reflects the distribution among the women who attended, not the frequency in the population; even so, it shows how often vaginismus comes up in outpatient clinics of this kind ⁵.

The same study also shows that vaginismus is often accompanied by other sexual function problems. Among 36 women with lifelong vaginismus, painful intercourse (dyspareunia) was also present in 47.2%, difficulty reaching orgasm in 22.2% and low sexual desire in 16.6% ⁵. The author notes that cultural factors may play a part in how this condition arises and recommends a “multidimensional assessment” for sexual function problems ⁵. In practice, this means that the assessment does not focus only on the contraction; pain, desire, relationship dynamics and the distress the person feels about the condition are considered together ^1,5.

Why does it happen?

Vaginismus has more than one cause; a cycle between body and mind is described. In the diagnostic criteria cited by ACOG, fear or anxiety about pain sits alongside tightening of the pelvic floor muscles ¹: expecting pain tightens the muscles, tight muscles make penetration painful or impossible, and each negative attempt reinforces the fear. In the randomised study, fear of intercourse, pain and sexual distress were measured together and decreased with treatment, which shows both sides of this cycle ³. ACOG defines sexual function problems in terms of the distress the person experiences and proposes a framework in which physical, psychological and relationship factors are assessed together ¹.

Fear of pain is a defining part of this cycle; ACOG also lists negative attitudes towards sex and a history of sexual trauma among the factors that may contribute ¹. The same guideline sees information about the anatomy of the external genital area (vulva) and the vagina, and about the pelvic floor, as one component of treatment ¹. Physical contributing factors are also reviewed: ACOG recommends looking for gynaecological causes through history-taking and examination; these include the postnatal period (birth trauma, dryness related to breastfeeding) and the genitourinary syndrome of menopause (changes involving dryness and pain) ¹. One of the tasks of a gynaecological assessment is to distinguish between these factors.

How is the assessment carried out?

The first consultation begins with a conversation. Questions cover how long the symptom has lasted, whether there has been any previous experience of intercourse, tampons or examination, where the pain is and what it is like, the level of fear and the partner’s attitude. ACOG recommends that the doctor asks these questions, because women do not talk about it unless they are asked ¹. The guideline recommends a detailed history and an examination looking for gynaecological causes at the first assessment ¹; whether and when a pelvic examination is carried out is decided jointly by the doctor and the person ⁶. Because insertion of the examination instrument can also trigger the contraction ³, this step is as much a part of building trust as of the assessment itself.

By the end of the assessment, it becomes clear whether the vaginismus is lifelong (primary) or acquired (secondary), and what accompanying sexual function problems and physical contributing factors there are; the plan is then drawn up individually on this basis, taking the person’s priorities into account. This framework covers gynaecological assessment and treatment and, where needed, collaboration with mental health professionals; ACOG also recommends considering consultation with, or referral to, mental health professionals ¹. The aim is not to apply a particular method but to arrive at a plan that fits the person’s situation. A recent review of studies from 2015–2025 also reports that integrated approaches combining psychological and physical methods stand out ².

What approaches are there, and what do studies say?

A step-by-step behavioural approach involves learning to relax the pelvic floor muscles, using graded dilators (vaginal dilators) under the woman’s own control, and involving the partner; ACOG recommends pelvic floor muscle training and psychological methods ^1,3. The main randomised study is an example of this: 70 women with lifelong vaginismus and their partners were allocated either to an intensive programme of at most three two-hour sessions in one week, in which the woman did the exercises herself accompanied by her partner and a female clinician, or to a waiting list ³. In the treatment group, 31 of 35 women (89%; 95% confidence interval 72–96%) were able to have intercourse; on the waiting list, 4 of 35 (11%) ³.

A 2018 review carried out two separate analyses: when 43 observational studies (1,660 women) were pooled, about 79% of women (95% confidence interval 74–83%) were able to have intercourse regardless of the method, and 82% in moderate-to-high-quality studies; in the analysis of 3 randomised studies (264 women), a trend in favour of the active approach was seen, but the difference did not reach statistical significance ⁴. The authors report that no method was superior to another and urge caution, because the observational data had no comparison group ⁴. In a 2026 review covering 18 studies and 863 women, rates by method ranged from 78% (dilator use) to 86% (combined psychosexual approach) ².

Limits of the evidence and realistic expectations

These percentages are high, but they need to be read in context. A 2012 review by the independent evidence network Cochrane examined 5 studies; with 282 women in the 4 studies able to provide data, it could not show a clinical or statistical difference between systematic desensitisation and control conditions, no meta-analysis could be carried out, and it asked for the results to be interpreted with caution ⁷. This does not mean that the method is ineffective, but that at that time there were few high-quality comparative studies ⁷. The 2018 review does not find any method superior to another ⁴. The 2026 review, for its part, states that integrated approaches appear to be the most effective and draws attention to differences in definitions between studies ².

How long the process takes varies from person to person. In the randomised study, 90% of the women who were able to have intercourse had done so within the first two weeks; however, this result comes from a selected group of 70 people enrolled in an intensive programme ³. In the 2018 review, the rate was lower (68%) in studies that selected participants using the criterion of “unconsummated marriage” ⁴. For women who also have pain, desire or relationship problems, the plan needs to cover these areas as well ^1,5. What shapes expectations is not a promise but the individual picture that emerges from the assessment. Vaginismus is a condition that can be addressed with scientific methods, and in studies the great majority of women benefited ⁴.
