Dyspareunia

What is dyspareunia?

Pain felt in the genital or pelvic area during (or after having) vaginal sex is called dyspareunia.

It can be divided into either superficial or deep dyspareunia. Superficial means it is felt on the surface of the genital region. Deep dyspareunia is felt deep in the pelvis. They have different causes and treatments and, although it's possible to experience both at the same time, most women find that their dyspareunia is predominantly one or the other type.

Superficial dyspareunia

This is pain felt in the lips of the vagina (labia), at the vaginal entrance (introitus) and the lower part of the vagina. It typically begins with penetration or very early on after intercourse has begun. It is sore and instant. It is usually quickly relieved by stopping penetration, although you may be sore to the touch afterwards for a little while. The causes of superficial dyspareunia are usually local problems of the labial, vaginal and perineal skin (the perineum is the area of skin between the vaginal opening and the back passage).

Deep dyspareunia

This is the term for pain felt deeper in the pelvis during or after intercourse. It can also spread to involve the fronts of the thighs. It may be sharp or dull, may stop when penetration stops or can continue for minutes or even hours. The causes of this type of pain usually lie rather deeper in the pelvis.

Understanding vulvodynia and why it causes painful sex

Vulvodynia is a leading cause of painful sex and affects up to 3.2 million women in the UK, yet it is often misdiagnosed and under-reported. It affects the vulva - the area surrounding the entrance to the vagina, including the labia and clitoris. Sally Turner shares her experience of living with the condition and uncovers the latest thinking on causes and treatments.

Pelvic inflammatory disease

Pelvic inflammatory disease (PID) is an internal infection which has usually passed into the womb (uterus) and its surrounding organs from the vagina or neck of the womb (cervix). It may also affect the lower abdominal area (pelvis) around these organs. It is important to treat it with antibiotics to prevent complications. In most cases the infection is passed on through sex (a sexually transmitted infection - STI).

Causes of superficial dyspareunia

Skin bridge

Formation of a little bridge of scar tissue at the very back of the vaginal entrance (introitus) is common after childbirth, particularly if you have had a cut between the vagina and back passage (anus) - a procedure called episiotomy. The scar tissue contains nerve endings and is very sensitive, and so it causes pain on penetration. The pain tends to become worse as having sex (intercourse) continues, as the skin bridge becomes rubbed by the continuing rubbing of penetration.

Intact hymen

The hymen is a membrane that lines the vaginal opening. Early in your sex life the hymen is broken down by the act of having sex. In many young women it will already have been stretched by use of tampons. The name 'intact hymen' is misleading, as the hymen does in fact have a small hole in it from birth. This hole becomes larger little by little as girls grow older. However, the hymen can be quite thick and the hole not quite large enough. This can mean that early in her sexual life a woman may feel pain from the hymen as it is forced open the first time she has intercourse. The pain is superficial, is felt at the entrance to the vagina as soon as penetration is attempted and may prevent it from taking place.

Vaginismus

Vaginismus causes a powerful and often painful contraction of the muscles around the entrance to the vagina, which makes penetration painful or impossible. It may also prevent the use of tampons and any sort of gynaecological examination. The spasm of vaginismus is not something you can cause deliberately; it's completely outside your control. It may seem to begin for no reason but can also result from a painful or worrying experience of sex, when it becomes a kind of protective reflex.

However, vaginismus is upsetting and dispiriting for both halves of a couple, as it can prevent the enjoyment of sex for many years and can prevent sex completely. Once it has begun, fear of failure and nervousness about not being able to have sex make it worse. It's important to seek help to break the cycle of anxiety and pain. Vaginismus is not difficult to treat but your doctor may need to refer you to a psychologist or a specialist physiotherapist.

Bartholinitis

Bartholin's glands are a pair of glands on either side of the vagina, in the tissues of the wall. They can become inflamed and tender causing Bartholinitis and this will lead to pain during sex. Occasionally, the glands swell during sex, so that it starts off as painless but then becomes painful as it continues.

See the separate leaflet called Bartholin's Cyst and Abscess for more details.

Vulvodynia

This is a very troublesome condition where the vulval area becomes painful and extremely sensitive to pressure and touch. It can be accompanied by severe pain on attempted penetration. It can also cause the vulval area to be painful when touched and during activities of everyday living. It can lead to frustration and depression, as symptoms can be very long-standing. The causes are uncertain but may involve the nerves in the area becoming much more sensitive than normal and the way the brain communicates with these nerves changing in some way. Treatment includes the use of emollient soap substitutes, creams that numb the area, medicines that lessen pain, physiotherapy and cognitive behavioural therapy.

Lichen sclerosus

This is a scarring skin condition which may affect women of any age, including children. It can affect men too. It results in thinning of the skin of the genital area, together with formation of white patches. It may be caused by the immune system. It causes itching and pain, which can last for a very long time. It's often mistaken for thrush as it can be very itchy and sometimes slightly sore. Lichen sclerosus carries a small risk risk of cancer of the genital skin. For this reason it should be diagnosed and treated - treatment is usually with regular application of creams.

See the separate leaflet called Lichen Sclerosus for more details.

Female genital mutilation

Female genital mutilation (which used to be known as female circumcision) involves varying degrees of mutilating surgery to the genitals of a girl. In the more extreme forms, the vagina is stitched shut. Following genital mutilation there is usually permanent scarring, which may lead to damaged nerves and pain. Any of these issues can cause pain on penetration and may make sex impossible.

Vaginal abnormalities

Very rarely, abnormalities of the vagina itself make sex painful or even impossible. These include pieces of extra tissue inside the vagina which are present at birth (vaginal septa).

Causes of superficial and deep dyspareunia

Vaginal trauma

The vagina is pretty flexible and strong and usually recovers well from the stretch and (sometimes) small tears of childbirth. However, more significant injury to the vagina - for example, from difficult childbirth or mutilation - can lead to scarring and then to pain and difficulty during sex (intercourse).

Vaginal or genital infection

Infections of the vagina and the area around it cause inflammation of the tissues and so commonly cause pain on having sex. Infection may be with thrush (candida - a yeast that often lives in the bowel), with viruses such as herpes and with germs (bacteria). A wide range of bacterial infections can infect the vagina. Some (but by no means all) are sexually transmitted. The vagina is not always sore and itchy before sex but becomes so afterwards. There is often a coloured discharge and you may notice an offensive smell.

See the separate leaflets called Vaginal Thrush (Yeast Infection), Genital Herpes and Bacterial Vaginosis for more details.

Vaginal dryness

Sometimes pain during sex is due to lack of lubrication, meaning that the vagina is too dry. Normally, the vagina produces secretions which keep it moist and these increase when you become sexually aroused. If there isn't enough foreplay, or you are not aroused enough, you may not produce enough secretions to make penetration comfortable.

However, it isn't always as simple as that. There may be reasons why you don't produce the secretions that you should. These can include psychological reasons such as nervousness because sex has previously been uncomfortable; anxiety around becoming pregnant; or anxiety around waking your sleeping children. Dryness can also be for physical reasons - the vagina tends to be drier after the menopause (see below). Some medicines can cause vaginal dryness, including some contraceptive methods. Vaginal dryness is also associated with a condition called Sjögren's syndrome, in which the body's secretions are generally rather reduced. Finally, pregnancy itself can make the vagina dry during intercourse (although it can also have the opposite effect).

Vaginal atrophy

After the menopause the levels of hormones in your body fall - particularly the level of oestrogen. Oestrogen is the hormone that keeps the vaginal wall strong and resistant. It increases the blood supply and the level of secretions and makes the wall softer and more stretchy. Therefore, when oestrogen levels fall after the menopause, the tissues become thinner, less stretchy and less well lubricated. Sometimes they can become as fragile and delicate as the vaginal tissues of young girls (who have not yet reached puberty and started their periods). There are lots of very effective treatments for this problem.

See the separate leaflet called Vaginal Dryness (Atrophic Vaginitis) for more details.

Causes of deep dyspareunia

Deep dyspareunia can be caused by the genital organs themselves but may also be caused by other structures in the tummy (abdomen) that can be easily knocked during sex (intercourse). There are therefore many possible causes of deep pain in the tummy during sex.

Cervical pain

The neck of the womb (cervix) should not normally be painful. However, if can become infected by many of the organisms which can infect the vagina - particularly herpes. If the cervix becomes inflamed then knocking it with the penis during sex may cause deep pain in the pelvis and sometimes across the fronts of the thighs. The cervix may also become tender and sensitive if you have an intrauterine contraceptive device, particularly if it is sitting a little too low or falling out. This can cause sudden sharp pains in the cervix during sex. (Fortunately cervical cancer is very rare and does not usually cause painful sex.)

Endometriosis

Endometriosis is a condition in which little bits of womb (uterine) lining become embedded in other parts of the body. Most usually this is in the ovaries, the Fallopian tubes that link the womb to the ovaries, and the cervix. These bits of tissue bleed whenever you have a period. This blood tends to cause scar tissue formation with sticking of organs to one another, and the whole pelvis can become painful.

Endometriosis is typically found in young women, and may only become apparent when they come off the contraceptive pill if they have been taking it for a while. This is because 'the pill' suppresses it and is, in fact, a treatment for endometriosis. Endometriosis causes pain on sex, typically pain that comes on with deep penetration and continues for some time after penetration is over. It also causes painful periods, and women with endometriosis can find it difficult to get pregnant.

See the separate leaflet called Endometriosis for more details.

Ovarian cysts

The presence of cysts on the ovaries can cause pain during sex (intercourse). This is because the ovaries can be knocked by the penis during intercourse and this can cause the cysts to leak fluid. It's not unusual to have cysts on the ovaries, as cyst formation is a normal part of the period (menstrual) cycle. However, these 'physiological cysts' are typically very small. Larger cysts are more likely to leak and cause pain, and can be a sign of endometriosis, especially in younger women. In women who have passed their menopause, ovarian cysts are worrying, as they can be a sign of ovarian cancer. See the separate leaflet called Ovarian Cyst.

Another, harmless form of pain from the ovary is called 'Mittelschmerz'. This is pain when an egg is released from the ovary. Pain from Mittelschmerz may not be related to sex at all, and typically lasts for two or three days in the middle of the month - but sex may make it worse when it's there.

Fibroids and growths in the womb

Fibroids are non-cancerous (benign) growths in the muscle of the womb, which can cause the womb itself to become quite bulky. This is not always painful but it can lead to discomfort during sex. See the separate leaflet called Fibroids.

Causes related to womb position

In some women the womb tilts backwards, rather than forwards; the ovaries then tend to fall backwards too. This can lead to them being knocked in positions involving deep penetration. This can result in deep pain in the pelvis that is more noticeable with deep penetration and which settles slowly when penetration stops or when you change your position.

Bowel pain

During intercourse the bowel is also knocked and moved. If the bowel is sensitive or tender then this can be the origin of pain during sex. This is particularly likely in women who have Crohn's disease, ulcerative colitis or irritable bowel syndrome, all of which are conditions that cause the bowel to be painful.

See the separate leaflets called Irritable Bowel Syndrome, Crohn's Disease and Ulcerative Colitis.

Pelvic inflammatory disease

This is a condition of the Fallopian tubes, the womb and, sometimes, the ovaries. It is caused by infection and makes these organs inflamed. As they tend to move during sex, this is painful. The pain is typically felt deep in the pelvis, is worse with deep penetration and settles slowly when penetration stops. Pelvic inflammatory disease also tends to make you feel unwell, and may cause a temperature and a vaginal discharge. See the separate leaflet called Pelvic Inflammatory Disease.

Bladder pain

The bladder sits on top of your womb, just behind and above your pubic bone. Like the womb, the bladder moves and gets pressed on during intercourse. So, if the bladder is inflamed, this may hurt. Typical causes include urine infections and interstitial cystitis. This is a condition in which the bladder becomes sensitive and painful. It behaves like a urine infection but no infection is present.

Summary

Symptoms of dyspareunia (pain felt in the pelvis during or after sex) are distressing and depressing. They can affect your sex life, your fertility and even your relationship. Many of the causes have a very simple solution and it is important to seek help if you are experiencing problems.
