OBJECTIVETo explore the best therapy for infertility caused by polycystic ovary syndrome (PCOS).

METHODSOne hundred and twenty patients were randomized into three groups, a clomi-phene group (group A), an acupuncture-moxibustion + Chinese medicine group (group B) and a clomiphene + acupuncture-moxibustion+ Chinese medicine group (group C), 40 cases in each one. In the group A, since the 5th day of menstruation, clomiphene was prescribed for oral administration. In the group B, on the 5th day of menstruation, warm needling therapy was applied at Zhongji (CV 3), Guanyuan (CV 4), Guilai (ST 29), etc. Additionally, the Chinese herbal medication for tonifying the kidney and activating blood circulation was provided. In the group C, the therapy as the group B was combined on the basis of the treatment as the group A. The treatment lasted continuously for 3 menstrual cycles. The endometrial thickness, endometrial type and cervical mucus score on human chorionic gon adotropin (HCG) day, and ovulatory cycle rate, clinical pregnancy rate and abortion rate after treatment were observed in the patients of the three groups.

RESULTS1) HCG day cervical mucus score, endometrial thickness and endometrial morphology (A type rate): the results in the group C were better than those in the group A (all P<0.01); the results in the group B were better than those in the group A (all P<0.05). The difference in the endometrial thickness was not significant in comparison between the group C and the group B (P>0.05). The cervical mucus score and endometrial morphology (A type rate) in the group C were better than those in the group B (both P<0.05). 2) The ovulatory cycle rates in the group A and group (C were higher than that in the group B (both P<0.05), the pregnancy rate in the group C was higher than that in the other groups (both P<0.05), and the early abortion rate in the group C was lower than that in the group A and group B (both P<0.01). 3) Follicle diameter from 18 mm to 20 mm and endometrial thickness: the differences were not significant between the normal pregnancy patients and the early abortion patients (both P>0.05). The endometrial morphology A type rate in the normal pregnancy patients was higher than that in the early abortion patients (P<0.05).

CONCLUSIONThe combined therapy of acupuncture, herbal medicine and clomiphene improves the pregnancy rate and reduces early abortion rate by effectively improving HCG day cervical mucus, endometrial thickness and morphology. The efficacy is apparently superior to the simple medication with clomiphene and the combined application of acupuncture and herbal medicine.
