Symptoms of输囊管 (likely referring to "biliary duct" or "cystic duct") obstruction

Symptoms of fallopian tube blockage (commonly referring to tubal occlusion) vary and mainly include the following aspects: 1. **Infertility**: Tubal blockage prevents the sperm and egg from combining to form a fertilized egg, making it one of the primary causes of female infertility. This symptom usually can only be diagnosed after a period of attempted conception. 2. **Dysmenorrhea and menstrual irregularities**: Pelvic congestion caused by inflammation may lead to淤血性痛经 (stagnant blood dysmenorrhea), typically starting about a week before menstruation and worsening as the menstrual period approaches. Additionally, if the inflammation involves the ovaries, it may impair ovarian function and cause menstrual irregularities. 3. **Abdominal discomfort**: Patients often experience varying degrees of dull pain or discomfort in the lower abdomen. Pain, soreness, distension, and a sensation of pressure in the lower back and sacral area may also occur. These symptoms tend to worsen after physical exertion. 4. **Other symptoms**: Additional systemic symptoms may include increased vaginal discharge, pain during intercourse, fatigue, and mental depression. These symptoms are often associated with acute or chronic inflammatory infections of the fallopian tubes. If these symptoms occur, it is recommended to seek timely medical evaluation for early detection and treatment.
