I now have comprehensive content from multiple authoritative textbooks. I have enough to write a thorough 10-mark answer. Let me compose the full answer.

Dyspareunia - Definition, Causes, Clinical Features & Management

Definition

Dyspareunia is defined as recurrent or persistent genital pain that occurs before, during, or after sexual intercourse. The word is derived from the Greek dyspareunia meaning "badly mated." It is predominantly a condition affecting women, though it can occur in men.
Under DSM-5, dyspareunia has been subsumed into the broader category of Genitopelvic Pain/Penetration Disorder (GPPPD), which encompasses: difficulty having intercourse, genitopelvic pain, fear of pain or penetration, and tension of the pelvic floor muscles. For clinical purposes, however, dyspareunia remains a distinct and useful diagnostic entity.
Dyspareunia is distinct from pain caused merely by lack of vaginal lubrication and from vaginismus (involuntary spasm of the outer one-third of the vagina), though the conditions frequently coexist and can lead to one another.
(Smith and Tanagho's General Urology, 19th Ed.; Kaplan & Sadock's Synopsis of Psychiatry)

Classification

Dyspareunia may be classified based on location of pain:
TypeLocationCommon Causes
Superficial (Introital)At the hymen/vestibuleVestibulitis, vaginismus, hymenal remnants, Bartholin gland infection
Vaginal (Mid-vaginal)Introitus to cervixVaginitis, cervicitis, lack of lubrication, vaginal atrophy
Deep (Pelvic)Supracervical/deep pelvicEndometriosis, fibroids, ovarian cysts, PID
It is also classified as:
  • Primary (Lifelong) - present from the first sexual experience
  • Secondary (Acquired) - onset after a period of pain-free intercourse
  • Generalised vs Situational

Epidemiology

  • Affects approximately 7-32% of women over their lifetime
  • Relatively uncommon in premenopausal women (~5%), but prevalence rises to 12-45% postmenopausally
  • Most common at extremes of reproductive age (young women - psychorelational causes; older women - vulvovaginal atrophy)
(Campbell-Walsh-Wein Urology; Smith & Tanagho's General Urology)

Causes / Etiology

Dyspareunia has both organic (physical) and psychogenic causes; in practice, they often coexist.

A. Organic (Physical) Causes

1. Structural/Anatomical
  • Congenitally imperforate or unusually thick hymen
  • Infected or painful hymenal remnants
  • Episiotomy scars, perineal tear scars
  • Vaginal stenosis (post-radiation or post-surgery)
  • Persistent hymen, protuberant labia
2. Infective / Inflammatory
  • Vaginitis (bacterial vaginosis, candidiasis, trichomoniasis)
  • Cervicitis
  • Bartholinitis (Bartholin gland infection)
  • Pelvic Inflammatory Disease (PID)
  • Genital herpes, gonorrhoea
3. Hormonal / Atrophic
  • Postmenopausal vaginal atrophy - thinning of vaginal mucosa, reduced lubrication (Genitourinary Syndrome of Menopause - GSM)
  • Testosterone deficiency
  • Long-term oral contraceptive pill use (mild vaginal thinning, reduced lubrication)
  • Postpartum hypoestrogenism (especially in breastfeeding mothers)
4. Dermatological / Vulvar Conditions
  • Vulvodynia / Vestibulodynia
  • Lichen sclerosus
  • Lichen planus
  • Neuroproliferative disorders of the vulvar vestibule
5. Pelvic / Deep Causes
  • Endometriosis (postcoital pain attributed to uterine contractions during orgasm)
  • Uterine leiomyoma (fibroids)
  • Ovarian cysts
  • Uterine retroversion
  • Pelvic congestion syndrome
6. Iatrogenic
  • Approximately 30% of all surgical procedures on the female genital area result in temporary dyspareunia
  • Mesh erosion after pelvic organ prolapse surgery
  • Radiation-induced vaginal stenosis
(Kaplan & Sadock's Comprehensive Textbook of Psychiatry; Smith & Tanagho's General Urology)

B. Psychogenic / Psychological Causes

  • Anxiety and tension about the sexual act causing involuntary pelvic floor muscle contraction
  • History of rape or childhood sexual abuse (chronic pelvic pain is a common sequela)
  • Negative attitudes towards sex from upbringing in conservative or restrictive cultures
  • Depression, anxiety disorders, catastrophising ("this pain will be unbearable")
  • Loss of self-efficacy
  • Partner-related issues (coercive intercourse before adequate arousal)
  • Anticipatory anxiety from previous painful episodes creating a vicious cycle
(Kaplan & Sadock's Synopsis of Psychiatry; Smith & Tanagho's General Urology)

Clinical Features

History

  • Pain before, during, or after intercourse
  • Location: introital (superficial) vs deep (pelvic)
  • Character: burning, tearing, stabbing, aching, throbbing
  • Duration, frequency, onset (primary vs secondary)
  • Associated symptoms: vaginal discharge, dryness, abnormal bleeding, urinary symptoms
  • Menstrual history - cyclical relationship (suggests endometriosis)
  • Contraceptive history, obstetric history, prior pelvic surgery or infections
  • Psychosexual history: relationship dynamics, history of abuse

Physical Examination

  • External genitalia: erythema, skin lesions (lichen sclerosus, herpes), vulvodynia testing with cotton-tipped swab (Q-tip test), Bartholin gland swelling
  • Vagina: evidence of atrophy (pale, dry, friable mucosa), vaginitis (discharge), scars, stenosis
  • Cervix: cervicitis, motion tenderness
  • Bimanual palpation: uterine tenderness, adnexal masses, uterosacral nodularity (endometriosis), uterine retroversion
  • Pelvic floor: assessment of muscle tone, trigger points

Investigations

  • Vaginal swabs for culture and sensitivity (exclude infections)
  • Pap smear / cervical cytology
  • Serum estrogen, FSH, LH, testosterone (hormonal assessment)
  • Pelvic ultrasound (fibroids, ovarian cysts, endometrioma)
  • Laparoscopy (diagnosis of endometriosis, adhesions)
  • pH of vaginal secretions (atrophic vaginitis - elevated pH >5)
  • Vulvar biopsy if dermatological lesion suspected

Management

Management must address both physical and psychological components. Failure to address both leads to suboptimal outcomes.

General Principles

  • Thorough history and meticulous physical examination
  • Treat the underlying cause
  • Multidisciplinary approach: gynaecologist, psychosexual therapist, physiotherapist
  • Patient and partner education
  • Encourage adequate foreplay and lubrication

A. Treatment of Specific Causes

CauseTreatment
Vaginal atrophy / GSMTopical/systemic oestrogen, vaginal moisturisers, lubricants
VaginitisAppropriate antibiotics/antifungals (e.g., metronidazole for BV, fluconazole for candidiasis)
EndometriosisHormonal therapy (OCP, GnRH analogues, progestins), laparoscopic ablation/excision
Bartholin abscessIncision and drainage, Word catheter insertion
Lichen sclerosusTopical high-potency corticosteroids (clobetasol)
Vulvodynia/vestibulodyniaTopical anaesthetics, tricyclic antidepressants, gabapentin, vestibulectomy
Hymenal remnantsSurgical excision (hymenectomy)
Post-radiation stenosisVaginal dilators, topical oestrogen, surgery
Mesh erosionSurgical removal of eroded mesh

B. Physical Therapies

  • Pelvic floor physiotherapy - first-line for high pelvic floor muscle tone, trigger point release, biofeedback
  • Vaginal dilators - graduated use for stenosis, vaginismus, or fear of penetration
  • Lubricants and moisturisers - water-based lubricants for intercourse; non-hormonal vaginal moisturisers (e.g., Replens) for daily use

C. Hormonal Therapies

  • Topical vaginal oestrogen (oestradiol cream, ring, tablet) - for atrophic vaginitis; safe even in most women with breast cancer history
  • Ospemifene - selective oestrogen receptor modulator (SERM) for postmenopausal dyspareunia
  • Testosterone - for testosterone deficiency-related dyspareunia

D. Psychological / Psychosexual Therapies

  • Sex therapy / psychosexual counselling - addresses anxiety, negative cognitions, relationship issues
  • Cognitive Behavioural Therapy (CBT) - addresses catastrophising, avoidance behaviour
  • Sensate focus exercises - progressive non-coital sexual exercises (Masters and Johnson technique)
  • Couples therapy - partner involvement is important
  • Psychological support for victims of sexual trauma
(Smith & Tanagho's General Urology, 19th Ed.; Campbell-Walsh-Wein Urology; Kaplan & Sadock's Comprehensive Textbook of Psychiatry)

Dyspareunia in Men

Though uncommon, dyspareunia can occur in men and is usually organic in origin:
  • Peyronie's disease (sclerotic plaques causing penile curvature)
  • Prostatitis
  • Gonorrhoea or herpetic infection
  • Vasocongestion without orgasm release ("blue balls")
  • Postejaculatory pain (involuntary perineal muscle spasm; may be a side effect of antidepressants)

Key Points Summary

  1. Dyspareunia = recurrent/persistent genital pain before, during, or after intercourse
  2. DSM-5 reclassifies it under Genitopelvic Pain/Penetration Disorder
  3. Can be superficial, vaginal, or deep based on location
  4. Causes are organic (structural, hormonal, infective, dermatological, pelvic) or psychogenic (anxiety, abuse, cultural factors)
  5. 30% of surgical procedures on female genitalia result in temporary dyspareunia
  6. Postmenopausal atrophy is the most common cause in older women; Vaginal atrophy/GSM affects 10-40% of postmenopausal women
  7. Thorough examination including pelvic floor tone is essential
  8. Management is multimodal: treat underlying cause + physiotherapy + psychosexual therapy
  9. Pelvic floor physiotherapy is a cornerstone of treatment
  10. Always involve the partner in therapy and counselling
