Since it does not flow out of the body, it stimulates the surrounding tissues, causing uterine muscle contraction or tissue fibrosis, which induces dysmenorrhea.

② Uterine adenomyoma: It is more common in women over 40 years old, multiparous women, and women who have had multiple abortions and curettages. It is also a common cause of secondary dysmenorrhea.

③ Cervical or uterine cavity adhesions: more common in patients with repeated abortions, endometrial tuberculosis, etc.

④ Reproductive tract malformation: mechanical obstruction such as excessive anteversion of the uterus and vaginal septum, which makes menstrual blood flow poorly and causes blood accumulation and induces secondary dysmenorrhea

⑤ Pelvic inflammation: It is also a common cause of secondary dysmenorrhea. It causes persistent pain in the lower abdomen, which may radiate to the waist, and is sometimes accompanied by a feeling of heaviness and distension in the anus.
