The effect of phytoestrogens (Cimicifuga racemosa) in combination with clomiphene in ovulation induction in women with polycystic ovarian syndrome: A clinical trial study.

OBJECTIVE

Phytoestrogens can be used as an alternative to clomiphene for ovulation induction in patients with polycystic ovarian (PCO). In this study, we evaluated the impact of phytoestrogens (Cimicifuga racimosa) in combination with clomiphene on the endometrium thickness and follicle number in women with PCO.

MATERIALS AND

METHODS

This study was a prospective clinical trial conducted in the infertility research center of Milad Hospital in Mashhad, Iran, during 2016 and 2017 on 100 women with PCO syndrome. The patients were randomly divided into two equal groups. The patients in both groups were treated by clomiphene citrate 50 mg, twice a day for 5 days, from the second day of the menstrual cycle and for three consecutive cycle periods. The intervention group received Cimicifuga racemosa tablets 10 mg twice a day for 10 days from the second day of the menstrual cycle, in addition to the mentioned standard treatment. The two groups were compared in terms of the number and size of follicles and endometrial thickness on the ultrasound.

RESULTS

There was no significant differences between the number of medium (p=0.288), large (p=0.086), and total (p=0.288) follicles between the two groups. Also, no significant difference was observed in endometrial thickness between the two groups (p=0.227).

CONCLUSION

As a result, adding Cimicifuga racemosa to clomiphene could not increase the endometrial thickness and the number of follicles in PCO patients.
