Résumé
To investigate the curative effect of electroacupuncture on luteinized unruptured follicle syndrome(LUFS) and its mechanism. Methods:Sixty LUFS patients were randomly allocated to treatment (electroacupuncture) group and control (hCG) group. The follicular condition and ovarian arterial flow under color Doppler ultrasonogaphy and a change in reproductive endocrine level were observed in the patients before and after treatments. The ovulation rates and pregnancy rates were compared between the two groups,and the mechanism was investigated. Results:Both ovulation rate and pregnancy rate were significantly higher in the treatment group than in the control group (P＜0.01). There was a significant difference in the improvement in ovarian arterial flow between the treatment and control groups (P＜0.01). The improvement in endocrine level was significantly more marked in the treatment group than in the control group(P＜0.01). Conclusion:Electroacupuncture has a good effect on luteinized unrupture follicle syndrome. Its mechanism may be related to the improvement in ovarian arterial blood supply and the regulation of endocrine level.
