Effects of Unkei-to on FSH, LH and estradiol in anovulatory young women with hyper- or hypo-functioning conditions.

Eight weeks treatment with Unkei-to induced a significant increase in plasma follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol levels in hyper- (robust) and hypo- (asthenia) functioning patients with first- and second-grade amenorrhea. We observed no significant differences in the rate of change of these hormones between hyper- and hypo-functioning patients. Ovulation occurred in 61.3% and 66.7% of patients with first-grade amenorrhea, and in 27.3% and 22.4% of patients with second-grade amenorrhea, respectively. No significant difference was observed in the ovulation rate after an 8-week treatment with Unkei-to between hyper- and hypo-functioning patients. These results indicate that Unkei-to is effective in improving gonadotropin and estradiol secretion in the treatment of either hyper- or hypo-functioning anovulatory women.
