Dyspareunia (Painful Intercourse)

Types of dyspareunia

Many people have more than one contributing factor. For example, vulvodynia often leads to protective pelvic floor tightening, which then becomes a pain source of its own.

How dyspareunia develops

Pain during sex sets up a cycle. Expecting pain reduces arousal and lubrication and tightens the pelvic floor muscles. That makes penetration more painful, which reinforces the expectation of pain. Over time, the nervous system can become sensitized, so even light touch hurts. This is why treating only the original trigger, such as an infection, sometimes does not fully resolve the pain.

Causes and risk factors

Hormonal changes

Menopause is the most common cause of acquired dyspareunia in older women. Falling estrogen thins and dries the vaginal tissue (vaginal atrophy). Up to half of postmenopausal women have symptoms. Breastfeeding, some hormonal contraceptives and cancer treatments such as aromatase inhibitors cause similar changes.

Vulvar pain conditions

• Vulvodynia: chronic vulvar pain without another identifiable cause, lasting at least 3 months. Provoked vestibulodynia is the most common cause of entry pain in premenopausal women.
• Vaginismus: involuntary tightening of the pelvic floor muscles with attempted penetration.
• Lichen sclerosus and lichen planus: inflammatory skin conditions that cause fissures and narrowing.

Pelvic conditions

• Endometriosis: the classic cause of deep dyspareunia, especially when lesions are behind the uterus.
• Adenomyosis and fibroids.
• Pelvic adhesions after surgery or infection.
• Interstitial cystitis (bladder pain syndrome) and irritable bowel syndrome.
• Pelvic floor dysfunction: overactive, tender pelvic muscles.

After childbirth

Painful sex is common in the first months after birth, especially after perineal tears or episiotomy, and while breastfeeding lowers estrogen. Most improve by 6 to 12 months, but persistent pain deserves assessment.

Infections

Vaginitis from yeast, bacterial vaginosis or trichomonas; genital herpes; and sexually transmitted infections leading to pelvic inflammatory disease.

Psychological factors

Anxiety, depression, relationship difficulties and past sexual trauma can contribute to and maintain the pain cycle. They are part of the picture, not a sign that the pain is "imagined."

Diagnosis

A careful, unhurried history is the most important step. The clinician asks about the location, timing and duration of pain, whether it is lifelong or new, menstrual, obstetric and sexual history, contraception, menopause, bladder and bowel symptoms, and emotional well-being.

The examination is adapted to the person's comfort and can be stopped at any time:

1. Visual exam of the vulva for skin changes, atrophy, scarring or lesions.
2. Cotton swab test: light touches at points around the vaginal opening to map pain (key for diagnosing vestibulodynia).
3. Single-finger exam to assess pelvic floor muscle tone and tenderness, and pain from the bladder or cervix.
4. Speculum and bimanual exam if tolerated, to check for tenderness, masses or nodules.

Tests may include vaginal swabs, STI tests, vaginal pH, a skin biopsy for suspected lichen sclerosus, and transvaginal ultrasound. Laparoscopy may be offered to diagnose and treat suspected endometriosis.

Treatment

Medical treatments

• Lubricants and vaginal moisturizers for dryness.
• Low-dose vaginal estrogen (cream, tablet or ring) for menopausal atrophy. Very little is absorbed, and it is safe for most women. Vaginal DHEA (prasterone) and oral ospemifene are alternatives.
• Topical lidocaine applied before sex for vestibulodynia.
• Treating infections and skin conditions, for example with antifungals, antibiotics or strong steroid ointment for lichen sclerosus.
• Nerve pain medicines such as amitriptyline or gabapentin for some vulvodynia.
• Hormonal suppression or surgery for endometriosis.

Pelvic floor physical therapy

A specialized physical therapist teaches pelvic floor relaxation, uses manual therapy and biofeedback, and may guide the use of graduated vaginal dilators. It is a first-line treatment for vaginismus, vulvodynia and pelvic floor dysfunction.

Psychological and sex therapy

Cognitive behavioral therapy, mindfulness-based approaches and sex therapy reduce pain and improve sexual function. Couples therapy helps partners communicate and find intimacy without pain while treatment works.

Surgery

Vestibulectomy, removal of the painful tissue at the vaginal entrance, is an option for severe provoked vestibulodynia not helped by other treatments. Surgery may also release scar tissue or treat endometriosis.

Outlook

With proper diagnosis and treatment, most people with dyspareunia improve, though it may take several months and more than one approach. Early treatment prevents the pain cycle from becoming entrenched. For practical, symptom-focused guidance on causes by location, see painful intercourse: why sex hurts.

Frequently asked questions

What is dyspareunia?

Dyspareunia is the medical term for persistent or recurrent pain with sexual intercourse. It can be felt at the vaginal entrance (superficial) or deep in the pelvis (deep), and it can be lifelong or develop later. It is common and usually treatable.

What is the most effective treatment for dyspareunia?

It depends on the cause. Vaginal estrogen works well for menopausal dryness, pelvic floor physical therapy for vaginismus and muscle tension, and topical or nerve pain treatments for vulvodynia. Many people do best with a combination that includes psychological support.

What is the difference between superficial and deep dyspareunia?

Superficial dyspareunia is pain at the vaginal opening with initial penetration, often from dryness, vulvodynia, infection or muscle spasm. Deep dyspareunia is pain inside the pelvis with deeper thrusting, typically from endometriosis, adhesions, adenomyosis or bladder and bowel conditions.

Can dyspareunia be cured?

Many cases resolve completely once the cause is treated, such as an infection or menopausal dryness. Chronic conditions such as vulvodynia or endometriosis may need ongoing management, but most people achieve comfortable sex with the right combination of treatments.
