RESUMEN
<p><b>OBJECTIVE</b>To explore the effect of Yijing Huoxue Cuyun Decoction (YHCD) in adjusting hypoestrogenemic response induced by clomiphene.</p><p><b>METHODS</b>Infertile patients caused by ovulation disturbance were randomly divided into 2 groups. The 60 patients in the observed group were treated with clomiphine plus YHCD, and the 58 patients in the control group were given clomiphine plus estradiol valerate.</p><p><b>RESULTS</b>By scoring on the cervical relaxation and improvement of cervical mucus, 38 patients (63.3%) in the observed group had Insler score of more than 8 points, while that in the control group was only 25 (43.1%), comparison between the two groups showed significant difference (P < 0.05). The endometrium thickening in the observed group was 0.98 +/- 0.19 cm, significantly different to that in the control group (0.85 +/- 0.21 cm, P < 0.01). Twenty-five patients in the observed group (41.7%), and fourteen patients in the control group (24.1%), respectively got pregnancy, the pregnant rate in the former was obviously higher than that in the latter (P < 0.05).</p><p><b>CONCLUSION</b>YHCD can ameliorate hypoestrinemia induced by clomiphene and increase the pregnant rate in patients.</p>
