Objective:To analyze the clinical characteristics of patients with amenorrhea after induced abortion.Methods:The patients with amenorrhea after induced abortion in our hospital of the past 5 years were analyzed retrospectively.Some characteristics of the patients were recorded

including sex hormone level

results of hysteroscopy

diagnostic curettage pathological Results

as well as prognosis.Results:A total of 37 patients(1.4%) suffered amenorrhea 2 to 16 months after induced abortion

which sustained for 2 to 5 months.The occurrence of amenorrhea was positively related to the frequency of induced abortion(χ2 = 13.440

P = 0.001)

but had nothing to do with delivery(χ2 = 0.037

P = 0.847).Sex hormone level revealed premature ovarian failure or hypothalamic amenorrhea dysfunction in 8 patients(21.6%).Hysteroscopic examination revealed 11 patients had cervical adhesions(29.7%)

and 18 patients had intrauterine adhesions(48.6%).Inflammatory cells accounted for 64.0% in all scrapings.After active treatment

35 patients resumed menstrual cycle

but the other two patients found it ineffective.Conclusion:The induced abortion may lead to complication like postoperative amenorrhea.Cervical or uterine adhesions

and abnormal sex hormones are the main reasons for amenorrhea

and inflammatory response may also play a role in it.Postoperative amenorrhea may have a good prognosis after treatment.
