Endometriosis

The exact cause of endometriosis is still unknown, but research has identified several risk factors that may increase the likelihood of developing the condition. Some cannot be changed, while others relate to hormonal patterns and menstrual history. Commonly recognized risk factors include:

• Early onset of menstruation
• Short menstrual cycles
• Prolonged exposure to estrogen
• A close blood relative with endometriosis
• Uterine or menstrual flow abnormalities
• Low body mass index
• Alcohol consumption

Because many of these factors are unavoidable, early awareness and ongoing medical care are critical. Tracking symptoms, noticing changes in menstrual patterns, and advocating for evaluation when pain feels excessive or progressive can support earlier diagnosis and better long-term management.

Endometriosis can develop years after a first period, may improve during pregnancy, and typically resolves after menopause. This creates a span of 20 to 30 years during which symptoms may affect quality of life. For many people, the condition is ultimately identified when fertility challenges arise, a symptom that is less easily mistaken for typical menstrual discomfort or digestive issues.

Symptoms vary widely and do not always correlate with the stage of the disease.

Common symptoms include:

• painful periods that worsen over time
• chronic pelvic pain
• pain during or after sex
• heavy menstrual bleeding
• digestive symptoms such as bloating, diarrhea, or constipation
• fatigue
• difficulty conceiving

The Mayo Clinic notes that symptom severity does not necessarily reflect disease stage—some people with mild disease experience severe pain, while others with advanced disease may have few symptoms.

Lubricants do not treat endometriosis itself, but they can reduce friction and irritation during intimacy, particularly when vaginal tissues are sensitive due to inflammation, hormonal changes, or pelvic floor tension. Medical literature supports the use of lubrication to reduce superficial pain and tissue irritation during intercourse.

No. Medical and sex therapy literature consistently emphasizes that intimacy does not need to involve penetration to be fulfilling or healthy. External stimulation, mutual touch, oral sex, and non-penetrative use of pleasure devices are commonly recommended options for people experiencing dyspareunia.

Sexual health research published in The Journal of Sexual Medicine highlights that flexible definitions of intimacy are associated with better relationship satisfaction and reduced anxiety in individuals with chronic pelvic pain.

An orgasm is a feeling of intense physical pleasure and a release of tension, accompanied by involuntary, rhythmic contractions of the pelvic floor muscles. Some women actually feel pelvic contractions or a quivering of the uterus during orgasm, while some do not. Some women describe fireworks all over their body, while others describe the feeling as a tingle. 

Orgasms vary in intensity and frequency as well as the amount of stimulation necessary to trigger one. In fact, less than a third of women consistently have orgasms with sexual activity. Plus, orgasms often change with age, medical issues, or with the use of medications. 

If a woman is happy with the climax of her sexual activities, there's no need for concern. However, if one is bothered by lack of orgasm or with the intensity of orgasm, a conversation with one’s medical doctor should be initiated. Lifestyle changes and sex therapy may be beneficial.

Yes. Endometriosis is one of the leading causes of chronic pelvic pain.

Inflammation, scar tissue, and nerve sensitivity can cause persistent discomfort in the pelvic region even outside of menstruation. Over time, the nervous system may become more sensitive to pain signals, which can make symptoms more intense.

Studies summarized by the National Institutes of Health show that chronic pelvic pain is strongly associated with endometriosis and other pelvic inflammatory conditions.

Endometriosis is sometimes discovered during fertility evaluations.

Scar tissue and inflammation can interfere with ovulation, egg quality, or the movement of eggs through the fallopian tubes. However, many people with endometriosis are still able to conceive naturally or with medical assistance.

The American College of Obstetricians and Gynecologists (ACOG) reports that endometriosis is found in a significant percentage of people experiencing infertility.
