Adenomyosis is when the cells of the uterine lining grow into the muscular wall of the uterus. It is similar to endometriosis and can cause similar symptoms, such as pain and heavy bleeding in menstruation. There may also be no symptoms.
Adenomyosis is a relatively widespread condition. According to a qualitative analysis of 16 research studies, 20–88.8% of women who experienced adenomyosis symptoms had the condition, with an average of 30–35%. Most women receive a diagnosis within the ages of 32–38 years.
However, these figures
This article gives an overview of adenomyosis, including symptoms, causes, diagnosis, complications, and treatment.
Adenomyosis is a gynecologic condition where the cells that
During a person’s menstrual cycle, these “trapped” cells undergo stimulation by the hormones of the menstrual cycle, similar to the mucous membrane lining of the uterus. This can make menstrual cramps and bleeding more severe than usual.
The symptoms of adenomyosis vary throughout the menstrual cycle because of rising and falling levels of estrogen, which affect the shedding of the uterus lining.
Symptoms usually go away or improve after menopause, when a person’s estrogen levels naturally decrease.
Adenomyosis and endometriosis are very similar, but there are differences.
In adenomyosis, cells lining the uterus grow into the uterus muscle. In endometriosis, these cells grow outside the uterus, sometimes on the ovaries and fallopian tubes.
These two conditions are equally widespread, though endometriosis occurs more often in women in their
It is possible for a person to have both endometriosis and adenomyosis. The symptoms of both conditions should subside after menopause.
Adenomyosis symptoms vary widely among people. Around
Possible symptoms of adenomyosis include:
- heavy menstrual bleeding
- very painful periods
- pain during sex
- bleeding between periods
- worsening uterine cramps
- an enlarged and tender uterus
- general pain in the pelvic area
- a feeling that there is pressure on the bladder and rectum
- pain while having a bowel movement
Doctors are not sure what causes adenomyosis, but
- Fetal development: Adenomyosis may be present in a person before birth when the uterus first forms in a fetus.
- Inflammation: Inflammation that occurs in a person’s uterus during uterine surgery could also increase the risk of adenomyosis.
- Invasive tissue: Injury to the uterus, such as during a cesarean delivery or other surgery, may also cause adenomyosis. This is because the endometrial-like tissue grows into the muscle.
- Estrogen: Conditions that increase the time of exposure to estrogen may include menopause, a higher body mass index, or past use of hormonal contraceptives.
- Age: This condition can affect individuals of any age. However, many people do not receive a diagnosis of adenomyosis until during or after menopause after having a hysterectomy.
- Pregnancy: A high percentage of females with adenomyosis have had multiple pregnancies.
- Uterine surgery: Having previous surgery on the uterus, including cesarean delivery,
may increasethe risk of adenomyosis.
Diagnosing adenomyosis begins with a consultation with a doctor. They will likely take a medical history and perform a physical and pelvic exam.
A person will often feel tenderness in her uterus during the pelvic exam. If a doctor thinks that the uterus feels slightly enlarged and they suspect adenomyosis, they may consider other tests,
- Ultrasound: This allows the doctor to examine pockets of the uterus lining tissue in the muscle of the uterus.
- MRI: An MRI scan is a common way for the doctor to see the inner uterus muscle.
- Endometrial biopsy: Sometimes, the doctor will want to take a small sample of the endometrial tissue in the uterus for testing. While it will not help diagnose adenomyosis, it will rule out other causes of a person’s symptoms.
However, these tests will not give a definite diagnosis. It is only possible to definitively diagnose adenomyosis once a person has had a hysterectomy and a specialized doctor called a pathologist examines the uterus under the microscope.
Without treatment, adenomyosis may remain the same or worsen.
Treatment is not necessary if a person has no symptoms, is not trying to get pregnant, or is nearing menopause, which is when most people find relief from their symptoms.
However, there are many different treatment options
- Anti-inflammatory medications: Medications, such as ibuprofen, can reduce pain and discomfort.
- Medications: Oral contraceptive pills, progestin intrauterine devices, or injections (Depo-Provera) can help ease symptoms. In addition, doctors can prescribe gonadotropin-releasing hormone agonists or antagonists, but usually only in the short term, as they can induce false or temporary menopause. In rare cases, healthcare professionals may prescribe them for the long term if a person does not respond to other treatments.
- Uterine artery embolization: This involves placing a tube in a major artery in the groin and injecting small particles into the affected area. This stops the blood supply from reaching the area, shrinking the adenomyosis and reducing symptoms.
- Hysterectomy: The only definitive treatment for adenomyosis is the complete removal of the uterus. It may be an unsuitable option for a person who still wants to become pregnant unless all therapies have failed and they wish to prioritize pain relief over pregnancy.

Research into the relationship between adenomyosis, infertility, and pregnancy complications is still ongoing. One 2017 study showed that in patients with adenomyosis, the rate of pregnancy loss before 12 weeks of pregnancy is
A person who is not trying to get pregnant or not experiencing any symptoms may not require treatment. However, anyone who suspects adenomyosis should speak with their doctor for evaluation.

Adenomyosis is not a life threatening condition on its own.
Although the condition will go away once a person reaches menopause, it can cause severe discomfort and lead to complications before then.
An individual should consult their doctor if they suspect adenomyosis or endometriosis. Several treatments can help alleviate the symptoms.
