Dyspareunia is painful sexual intercourse due to somatic or psychological causes. The term dyspareunia covers both female dyspareunia and male dyspareunia, but many discussions that use the term without further specification concern the female type, which is more common than the male type. In females, the pain can primarily be on the external surface of the genitalia, or deeper in the pelvis upon deep pressure against the cervix. Medically, dyspareunia is a pelvic floor dysfunction and is frequently underdiagnosed. It can affect a small portion of the vulva or vagina or be felt all over the surface. Understanding the duration, location, and nature of the pain is important in identifying the causes of the pain. Numerous physical, psychological, and social or relationship causes can contribute to pain during sexual encounters. Commonly, multiple underlying causes contribute to the pain. The pain can be acquired or congenital. Symptoms of dyspareunia may also occur after menopause. Diagnosis is typically by physical examination and medical history. Underlying causes determine treatment. Many patients experience relief when physical causes are identified and treated. In 2020, dyspareunia has been estimated to globally affect 35% of women at some point in their lives.

Signs and symptoms

Those who experience pelvic pain upon attempted vaginal intercourse describe their pain in many ways. This reflects how many different and overlapping causes there are for dyspareunia. The location, nature, and time course of the pain help to understand potential causes and treatments. Some describe superficial pain at the opening of the vagina or surface of the genitalia when penetration is initiated. Others feel deeper pain in the vault of the vagina or deep within the pelvis upon deeper penetration. Some feel pain in more than one of these places. Determining whether the pain is more superficial or deep is important in understanding what may be causing the pain. Some patients have always experienced pain with intercourse from their very first attempt, while others begin to feel pain with intercourse after an injury or infection or cyclically with menstruation. Sometimes the pain increases over time. Pain may distract from feeling pleasure and excitement. Both vaginal lubrication and vaginal dilation decrease. When the vagina is dry and undilated, penetration is more painful. Fear of being in pain can make the discomfort worse. Pain may continue despite the original source being removed, due to the learned expectation of pain. Fear, avoidance, and psychological distress around attempting intercourse can become large parts of the experience of dyspareunia. Physical examination of the vulva (external genitalia) may reveal clear reasons for pain including lesions, thin skin, ulcerations or discharge associated with vulvovaginal infections or vaginal atrophy. An internal pelvic exam may also reveal physical reasons for pain including lesions on the cervix or anatomic variation. When there are no visible findings on vulvar exam that would suggest a cause for superficial dyspareunia, a cotton-swab test may be performed. This is a test to assess for localized provoked vulvodynia. A cotton tip applicator is applied at several points around the opening of the vagina; the patient reports the resulting pain on a scale from 0–10.

Causes

Dyspareunia in women

The cause of the pain may be anatomic or physiologic, including but not limited to lesions of the vagina, retroversion of the uterus, urinary tract infection, lack of lubrication, scar tissue, abnormal growths, or tender pelvic sites. Some cases may be psychosomatic, which can include fear of pain or injury, feelings of guilt or shame, ignorance of sexual anatomy and physiology, and fear of pregnancy. Common causes for discomfort on vaginal penetration include:

Dyspareunia in men

There are a number of physical factors that may cause sexual discomfort. Pain is sometimes experienced in the testicular or glans area of the penis immediately after ejaculation. Infections of the prostate, bladder, or seminal vesicles can lead to intense burning or itching sensations following ejaculation. Patients with interstitial cystitis may experience intense penis pain at the moment of ejaculation. Gonorrheal infections are sometimes associated with burning or sharp penile pains during ejaculation. Urethritis or prostatitis can make genital stimulation painful or uncomfortable. Anatomic deformities of the penis, such as exist in Peyronie's disease, may also result in pain during coitus. One cause of painful intercourse is due to the painful retraction of a too-tight foreskin, occurring either during the first attempt at intercourse or subsequent to tightening or scarring following inflammation or local infection. Another cause of painful intercourse is due to tension in a short and slender frenulum, frenulum breve, as the foreskin retracts on entry to the vagina irrespective of lubrication. In one study frenulum breve was found in 50% of patients who presented with dyspareunia. During vigorous or deep or tight intercourse or masturbation, small tears may occur in the preputial frenulum and can bleed and be very painful and induce anxiety, which can become chronic if left unresolved. If stretching fails to ease the condition, and uncomfortable levels of tension remain, a frenuloplasty procedure may be recommended. Frenuloplasty is an effective procedure, with a high chance of avoiding circumcision, giving good functional results and patient satisfaction. The psychological effects of these conditions, while little understood, are real, and are visible in literature and art.

Diagnosis

Differential diagnosis

Dyspareunia is a condition that has many causes and is not a diagnosis of itself. It is combined with vaginismus into genito-pelvic pain/penetration disorder in the DSM-5. Criteria for genito-pelvic pain/penetration disorder include multiple episodes of difficulty with vaginal penetration, pain associated with intercourse attempts, anticipation of pain due to attempted intercourse, and tensing of the pelvis in response to attempted penetration. To meet criteria for this disorder, a patient must experience the symptoms for at least six months and experience "significant distress". The differential diagnosis for dyspareunia is long because of its complicated and multifactorial nature. Often there are physiologic conditions underlying the pain, as well as psychosocial components that must be assessed to find appropriate treatment. A differential diagnosis of underlying physical causes can be guided by whether the pain is deep or superficial:

Treatment

The treatment for pain with intercourse depends on what is causing the pain. After proper diagnosis one or more treatments for specific causes may be necessary. For example: In addition, the following may reduce discomfort with intercourse:

History

Etymology

The word "dyspareunia" comes from Greek δυσ-, dys- "bad" and πάρευνος, pareunos "bedfellow", meaning "badly mated".

Classification

The previous Diagnostic and Statistical Manual of Mental Disorders, the DSM-IV, stated that the diagnosis of dyspareunia is made when the patient complains of recurrent or persistent genital pain before, during, or after sexual intercourse that is not caused exclusively by lack of lubrication or by vaginal spasm (vaginismus). After the text revision of the fourth edition of the DSM, a debate arose, with arguments to recategorize dyspareunia as a pain disorder instead of a sex disorder, with Charles Allen Moser, a physician, arguing for the removal of dyspareunia from the manual altogether. The most recent version, the DSM 5, has grouped dyspareunia under the diagnosis of Genito-Pelvic Pain/Penetration Disorder.
