Vaginismus involves involuntary pelvic floor muscle tightening that makes penetration painful or impossible, often linked to fear, anxiety, or past trauma. Effective multidisciplinary treatments, including physical therapy, CBT, and gradual desensitization, achieve success rates of around 80%.

Introduction
Vaginismus is characterized by persistent or recurrent involuntary tightening of the pelvic floor muscles surrounding the outer vagina, often triggered by attempted penetration or even anticipation of it. This article provides a comprehensive overview of vaginismus and highlights advances in its diagnosis and treatment.1,2
What is vaginismus?
Vaginismus is a genito-pelvic pain/penetration disorder characterized by involuntary contraction of the perineal or pelvic floor muscles that surround the outer vagina when penetration is attempted. It can make sexual intercourse, tampon use, or gynecological examination painful or impossible.1,2
Clinically, the condition is categorized as primary or secondary. Primary vaginismus refers to lifelong inability to achieve penetration due to pain and reflex spasm, whereas secondary vaginismus develops after a period of previously pain-free penetration, often linked to infection, trauma, or psychological distress.2
Because of cultural and personal stigma surrounding sexual pain, the global prevalence remains uncertain. Population prevalence is unknown; clinical settings report 5–17%, and general population estimates are typically 1–6%.1,6
Etiology and risk factors
Physiologically, vaginismus represents a form of pelvic floor muscle hypertonicity, in which muscles such as the bulbospongiosus, pubococcygeus, and levator ani contract reflexively in anticipation of penetration.1,5 This involuntary reaction may be part of a fear-avoidance response to real or perceived pain.2
Psychological factors are prominent. Studies consistently show that women with vaginismus experience elevated levels of anxiety, depression, and low sexual self-efficacy, and that a history of sexual or emotional abuse significantly increases risk. In one meta-analysis, odds ratios for sexual and emotional abuse were 1.55 and 1.89, respectively, among women with vaginismus.4
Secondary vaginismus may be triggered by painful medical or gynecological conditions such as endometriosis, chronic infections, or vaginal atrophy. Restrictive cultural or religious attitudes toward sexuality and lack of sex education have also been identified as significant sociocultural risk factors, especially in regions where intercourse before marriage is stigmatized.2,3,5
Evidence supports the biopsychosocial model of vaginismus, which integrates biological muscle hypertonicity with psychological fear and sociocultural conditioning. The resulting cycle of anxiety, spasm, pain, and avoidance often perpetuates the condition if untreated.2,6
Clinical presentation and diagnosis
The hallmark of vaginismus is a woman’s inability to tolerate vaginal penetration despite the desire to do so. Many describe it as a sensation of “hitting a wall”. The diagnosis relies primarily on detailed sexual and psychological history, supported by a gentle pelvic examination to assess muscle tone and rule out differential diagnoses such as dyspareunia or provoked vestibulodynia.1,2,6
Recent reviews emphasize that vaginal spasm is not always present in vaginismus, and electromyographic studies reveal variable muscle activity, suggesting that fear and avoidance may be stronger diagnostic markers than spasm alone.1,2
Validated tools like the Female Sexual Function Index (FSFI) and structured interviews help assess sexual function and monitor treatment progress. When examination causes significant distress, examination under anesthesia may be considered to exclude anatomic pathology.7
Therapeutic approaches
Current evidence supports multimodal, multidisciplinary management addressing both physical and psychological components of vaginismus. The 2018 systematic review by Maseroli et al. found that successful penetration was achieved in approximately 79% of patients across 43 studies, increasing to 82% when only high-quality studies were analyzed.2,3,6,9
Common first-line interventions include pelvic floor physical therapy, cognitive-behavioral therapy (CBT), and graduated vaginal dilator use. Physical therapy employs education, relaxation, manual release of tension, and biofeedback-assisted muscle control. CBT targets maladaptive beliefs and fear-avoidance cycles through psychoeducation and systematic desensitization.2,3,5–7
Vaginal dilator therapy enables self-paced exposure, helping patients gradually regain control and reduce anticipatory anxiety. Couples-based therapy is also recommended to enhance communication and reduce partner-related anxiety.2,3,7
For refractory cases, botulinum toxin A (Botox) may be considered with caution: a 2012 meta-analysis suggested benefit (pooled OR≈8.7), and a 2017 cohort reported clinically meaningful improvements; however, guideline-level sources describe the overall evidence as limited and call for more randomized trials.6,8,7
Prognosis and long-term outcomes
Most women respond well to therapy when both physiological and psychological factors are addressed. In the meta-analysis by Maseroli et al., multimodal therapy yielded 79–82% success rates for penetrative intercourse. Favorable outcomes are clinically associated with early engagement in care and addressing coexisting contributors, though high-quality prognostic data remain limited.6,9
Delayed or inadequate treatment can lead to chronicity, persistent sexual distress, and relationship strain. Long-term follow-up studies remain limited, and recurrence data are scarce, though most women report sustained improvement after comprehensive therapy.2
Conclusions
Contemporary evidence underscores that vaginismus is a biopsychosocial condition requiring integrated care. Combining pelvic floor physical therapy to reduce muscle hypertonicity with psychological interventions to dismantle fear and avoidance remains the gold standard. Botox may help selected refractory cases, but current evidence is limited, and further RCTs are needed. Promoting open dialogue and destigmatization can empower women to seek timely help and restore sexual well-being.2,6,9
