What causes lower abdominal pain resembling menstrual cramps after intercourse, and what should be done?
Many women previously did not experience dysmenorrhea, yet begin suffering from painful menstruation after initiating sexual intercourse with their husbands—leaving them utterly perplexed. Do you know what causes dysmenorrhea following sexual intercourse?

Why does lower abdominal pain resembling dysmenorrhea occur after intercourse—and what should be done?
Lower abdominal pain resembling dysmenorrhea after intercourse may stem from endometriosis or pelvic inflammatory disease (PID), requiring physician-guided pharmacological treatment.
1. Endometriosis: A common gynecological condition in women, endometriosis occurs when endometrial tissue—normally confined to the uterine cavity—migrates via the fallopian tubes into the pelvic cavity. Symptoms include dysmenorrhea, menstrual irregularities, and dyspareunia (painful intercourse). Under medical supervision, analgesics such as ibuprofen sustained-release capsules may be prescribed for pain relief. Hormonal therapies—including mifepristone tablets and medroxyprogesterone acetate tablets—may also be used. If symptoms persist despite conservative management, laparoscopic surgery may be necessary.
2. Pelvic Inflammatory Disease (PID): A common upper genital tract infection in women, PID is associated with compromised immune function, hormonal fluctuations, and invasion by exogenous pathogens. Clinical manifestations include lower abdominal pain, increased vaginal discharge, and fever. Treatment involves antibiotics prescribed by a physician—such as levofloxacin hydrochloride capsules or cefalexin capsules—as well as adjunctive therapy with compound metronidazole vaginal suppositories.
During recovery, patients should adhere to a light, bland diet and avoid spicy or irritating foods to prevent symptom exacerbation.
Dysmenorrhea results primarily from elevated intrauterine estrogen levels and increased prostaglandin synthesis, leading to localized vasoconstriction and uterine smooth muscle spasm. It is unrelated to frequency of sexual activity. Following intercourse, transient systemic and local vasodilation occurs, enhancing blood circulation—but this effect is short-lived and does not alleviate chronic dysmenorrhea. Conversely, overly frequent intercourse may disrupt the natural vaginal microbiota, increasing susceptibility to vaginitis. Therefore, moderate sexual activity benefits health, whereas excessive frequency should be avoided.
