Soyosan(SYS) is used in infertile. An attempt was to evaluate the influences of SYS on the serum concentrations of FSH, LH and estrogen(E_2), the histolgical and optical changes of ovary, weight of rats.
The results of the study were as follows
1. Blood FSH level increased in experimental group as compared with control group on 5th day and 10th day, which showed no efficacy.
2. Blood LH level increased in experimental group as compared with control group on 5th day, which showed no efficacy.
3. Blood E_2 level decreased in experimental group as compared with control group on 5th day and increased on 10th day, which showed no efficacy.
4. In histolgical observations of ovary, ovulation increased in experimental group as compared control group on 5th day and decreased on 10th day, which showed no efficacy.
5. In optically observations of ovary, weight of ovary showed no change in exerimental group as compared with control group on 5th day and 10th day.
6. Weight of rats increased in experimental group as compared with control group on 5th day, which showed efficacy.
According to these results, SYS did not influence on the ovulation and ovary, but increased weight of rats.
