Definition and Diagnosis
Vaginismus, classified within genito-pelvic pain/penetration disorder, involves persistent difficulty with vaginal penetration, marked pelvic floor muscle tightening or tension during attempted penetration, and significant fear or anxiety about pain or penetration, causing distress.
Epidemiology
Exact prevalence is difficult to establish due to underreporting, but it is a recognized and clinically significant cause of sexual difficulty and, in some cases, unconsummated marriage, occurring across cultures with variable rates reported in gynecological and sexual health clinics.
Risk Factors
Risk factors include a history of painful gynecological conditions, prior sexual trauma or abuse, restrictive or fear-based sexual upbringing, anxiety disorders, and prior painful attempts at penetration that establish a conditioned fear-tension-pain cycle.
Symptoms and Subtypes
Core features include difficulty with vaginal insertion of a penis, finger, tampon, or speculum, marked pelvic floor tightening on attempted penetration, and pronounced fear or anxiety anticipating pain, often leading to avoidance of gynecological exams or sexual activity altogether.
Diagnosis
Diagnosis is clinical, based on history and, where tolerated, gynecological examination to rule out organic causes of pain such as infection, endometriosis, or dermatologic conditions, alongside assessment of associated fear, anxiety, and pelvic floor muscle tension.
Treatment
Treatment typically combines pelvic floor physical therapy, progressive vaginal dilator training, and psychosexual therapy addressing fear and anxiety, often with partner involvement. Botulinum toxin injection to the pelvic floor musculature is used in refractory cases.
Prognosis
Prognosis is generally favorable with structured, gradual desensitization and pelvic floor therapy, and many individuals achieve comfortable penetration and improved sexual function with sustained treatment.
