Experiencing Pain During Intercourse? 5 Possible Medical Reasons Behind It

Pain during sexual intercourse is not something women should ignore or consider a normal part of sex. While occasional discomfort may occur due to inadequate lubrication or nervousness, recurring or severe pain can indicate an underlying medical condition that needs attention.

Medically known as dyspareunia, pain during intercourse can occur at the vaginal opening or deeper inside the pelvis. Its location, intensity, and timing, along with other symptoms, can help identify the possible cause.

Dr Lavanya Kiran, Director and Lead Consultant, Obstetrics and Gynaecology, KIMS Hospitals, Electronic City, Bengaluru, explains that persistent pain during penetration should be evaluated by a gynaecologist, as treatment depends on the underlying cause.

Here are five possible medical reasons behind pain during intercourse.

1. Vaginal Dryness

Vaginal dryness is a common cause of pain during intercourse.

According to the American College of Obstetricians & Gynecologists, when the vagina does not produce enough natural lubrication, penetration can cause friction, soreness, irritation, or a burning sensation.

Hormonal changes during menopause, after childbirth, and while breastfeeding can reduce vaginal lubrication. Certain medications and insufficient sexual arousal may also contribute to dryness.

Women may experience discomfort mainly at the vaginal opening, particularly during penetration. Using a water-based or silicone-based lubricant can help reduce friction. However, persistent dryness, especially when accompanied by other symptoms, should be discussed with a doctor.

2. Vaginal or Pelvic Infections

Vaginal infections and sexually transmitted infections (STIs) can cause inflammation, irritation, and pain during intercourse.

Yeast infections may cause itching, soreness and thick vaginal discharge, while bacterial vaginosis can lead to unusual discharge and an unpleasant, fishy smell. Some STIs, including chlamydia and gonorrhoea, can cause inflammation of the cervix or pelvic organs.

Infections may also cause burning during urination, lower abdominal pain, or bleeding after sex.

However, some infections produce few or no noticeable symptoms.

If an infection is suspected, a medical assessment is important to establish the cause and provide appropriate treatment. Depending on the diagnosis, treatment may involve antifungal medicines, antibiotics, or treatment for the affected partner.

3. Endometriosis

Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside it, commonly affecting the ovaries, fallopian tubes and other areas within the pelvis.

This tissue can trigger inflammation, scarring, and pelvic pain.

According to a study published in the Journal of Medicine and Life, some women with endometriosis experience deep pain during intercourse, particularly when penetration is deep.

The discomfort may worsen before or during menstruation.

Other symptoms can include painful periods, chronic pelvic pain, pain during bowel movements or urination during periods, and difficulty conceiving.

Painful intercourse alone does not confirm endometriosis, but recurring deep pain, especially when linked to the menstrual cycle, warrants a gynaecological assessment. Treatment may include pain relief, hormonal medicines or surgery, depending on the severity of symptoms and individual needs.

4. Ovarian Cysts, Fibroids and Other Pelvic Conditions

Certain conditions affecting the reproductive organs can cause pain or pressure during deep penetration.

Ovarian cysts, which are fluid-filled sacs on or inside an ovary, may cause pelvic discomfort, particularly when they become large or are associated with complications. Uterine fibroids, which are non-cancerous growths in the uterus, can also cause pelvic pressure or pain, depending on their size and location.

Other pelvic conditions, including pelvic inflammatory disease and adhesions (scar tissue), may contribute to discomfort during intercourse.

Women may experience deep pelvic pain, lower abdominal discomfort, heavy periods, or pain outside sexual activity. Persistent symptoms require medical evaluation, which may include a pelvic examination or ultrasound.

Sudden, severe pelvic pain, particularly with vomiting, dizziness, or fainting, requires urgent medical attention because it may indicate a complication such as ovarian torsion or a ruptured cyst.

5. Pelvic floor dysfunction

The pelvic floor consists of muscles that support the bladder, bowel, and reproductive organs. These muscles need to relax and coordinate properly during penetration.

When the muscles become excessively tight or do not relax as they should, penetration can cause pain, burning or a feeling of resistance. This is known as pelvic floor dysfunction and may occur alongside chronic pelvic pain or after childbirth.

Some women may also experience pain during tampon insertion or gynaecological examinations. The discomfort may be felt at the vaginal opening or deeper in the pelvis.

Treatment depends on the cause and may include pelvic floor physiotherapy, relaxation techniques and exercises guided by a trained professional. Women should avoid starting strengthening exercises such as Kegels without assessment, as these may worsen symptoms when the pelvic floor muscles are already too tight.

When To See a Gynaecologist?

Occasional discomfort does not always indicate a medical problem. However, pain that keeps returning, becomes severe, or interferes with sexual activity should not be ignored.

Consult a gynaecologist if intercourse causes persistent pain, or if it is accompanied by unusual discharge, itching, bleeding after sex, painful periods, or pelvic pain. Seek urgent medical care for sudden severe pelvic pain, heavy bleeding, fever or fainting.

Final Word

Pain during intercourse is a symptom, not something women have to tolerate. Identifying its cause can help ensure appropriate treatment and make sexual activity more comfortable. Open communication with a doctor is an important first step towards better reproductive and sexual health.
